World J Pediatr 2024; 20:643-652. [PMID: 38864998 PMCID: PMC11269412 DOI: 10.1007/s12519-024-00818-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 05/13/2024] [Indexed: 06/13/2024]
Abstract
BACKGROUND Although not universal, active care is being offered to infants weighing < 500 g at birth, referred to as ultra-low birth weight (ULBW) infants appropriate for gestational age. These infants have the greatest risk of dying or developing major morbidities. ULBW infants face challenges related to fluid and heat loss as well as skin injury in the initial days of life from extreme anatomical and physiological immaturity of the skin. Although there is an emerging literature on the outcomes of ULBW infants, there is a paucity of evidence to inform practice guidelines for delivering optimal care to this cohort of infants. DATA SOURCES A comprehensive review of the literature was performed using the PubMed and Embase databases. Searched keywords included "thermoregulation or body temperature regulation", "incubator humidity", "skin care", "infant, extremely low birth weight" and "ultra-low birth weight infants". RESULTS Evidences for thermoregulation, incubator humidity, and skincare practices are available for preterm infants weighing < 1500 g at birth but not specifically for ULBW infants. Studies on thermoregulation, incubator humidity, or skincare practices had a small sample size and did not include a sub-group analysis for ULBW infants. Current practice recommendations in ULBW infants are adopted from research in very and/or extremely low birth weight infants. CONCLUSIONS This narrative review focuses on challenges in thermoregulation, incubator humidity, and skincare practices in ULBW infants, highlights current research gaps and suggests potential developments for informing practices for improving health outcomes in ULBW infants.

Temperature probe placement in very preterm infants during delivery room stabilization: an open-label randomized trial. Pediatr Res 2024; 96:190-198. [PMID: 38443526 PMCID: PMC11257937 DOI: 10.1038/s41390-024-03115-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 02/01/2024] [Accepted: 02/17/2024] [Indexed: 03/07/2024]
Abstract
BACKGROUND Variation in practice exists for temperature probe positioning during stabilization of very preterm infants (<32 weeks gestation). We explored the influence of temperature probe sites on thermoregulation. METHODS An open-label, stratified, balanced, parallel, randomized trial was conducted. Inborn infants were randomly assigned temperature probe to the axilla or to the upper back. The primary outcome was normothermia (local range: 36.8-37.3 °C and World Health Organization (WHO) range: 36.5-37.5 °C) at admission to the neonatal intensive care unit. RESULTS Between 1 November 2018 and 4 July 2022, 178 infants were randomly assigned to one of the two sites (n = 89 each), 175 included in the final analysis. Normothermia (local range) was achieved for 39/87 infants (44.8%) assigned to the upper back compared to 28/88 infants (31.8%) assigned to the axilla [risk difference:13%; 95% CI -1.3-27.3]. Normothermia (WHO range) was achieved for 78/87 infants (89.7%) assigned to the upper back compared to 70/88 infants (79.6%) assigned to the axilla [risk difference:10.1%; 95% CI -0.5-20.7]. No infant recorded temperatures >38 °C or developed skin injury. CONCLUSIONS In very preterm infants, upper back site was equally effective as the axilla in maintaining normothermia, with no increase in adverse events. CLINICAL TRIAL REGISTRATION The study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12620000293965). IMPACT Substantial variation in practice exists for the site of securing a temperature probe during delivery room stabilization of very preterm infants and the influence of temperature probe site on thermoregulation remains unknown. In this study, upper back site was equally effective as the axilla in maintaining normothermia, with no increase in adverse events. Clinicians could adopt upper back site for maintaining normothermia. This study may contribute data to future international participant data prospective meta analysis of randomized controlled trials worldwide on temperature probe positioning in very preterm infants, increasing translation of research findings to optimize thermoregulation and clinical outcomes.

Abstract
AIM Hypothermia poses a threat to the health and lives of newborns. Therefore, it is essential to identify the factors that influence neonatal hypothermia and provide targeted intervention suggestions for clinical practice to reduce its occurrence. METHODS We conducted a literature search to identify factors influencing neonatal hypothermia and performed a meta-analysis to determine the prevalence of neonatal hypothermia and its associated factors. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of cohort and case-control studies, while the Agency for Healthcare Research and Quality (AHRQ) was used to evaluate the quality of cross-sectional studies. RESULTS Eighteen studies involving 44 532 newborns from 13 countries were included. The incidence of neonatal hypothermia was 52.5% (95% CI: 0.37, 0.68). Factors such as no skin-to-skin contact, prematurity, low birth weight, delayed breastfeeding, asphyxiation and resuscitation after birth, low APGAR score, not wearing a cap, and caesarean section were found to affect neonatal hypothermia. CONCLUSION Multiple factors influence neonatal hypothermia, and clinicians can utilise these factors to develop targeted intervention measures to prevent and reduce the incidence of neonatal hypothermia.

Lateral kangaroo position for thermal stability of extremely preterm: Non-inferiority randomized controlled trial. Nurs Crit Care 2024. [PMID: 38850068 DOI: 10.1111/nicc.13102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/09/2024] [Accepted: 05/23/2024] [Indexed: 06/09/2024]
Abstract
BACKGROUND Kangaroo care (KC) is an evidence-based best practice that can prevent major health complications in preterm infants. However, there is a lack of evidence on the feasibility and safety of placing extremely preterm infants under 28 weeks gestational age in KC position. AIM To compare thermal stability 60 min after the first KC session in the lateral versus prone position in extremely preterm infants under 28 weeks gestational age. STUDY DESIGN This is a single-centre, randomized, non-inferiority, parallel clinical trial. The patients were extremely preterm infants during their first 5 days of life. Infants in the intervention group received KC in the lateral position while those in the control group received KC in the prone position. All infants receiving KC were inside their polyethylene bags but maintained skin-to-skin contact. The primary outcome was the axillary temperature of the infants, and the secondary outcome was the development of intraventricular haemorrhage. RESULTS Seventy infants were randomized (35 per group). The mean gestational age was 26 +1(1+1) in both groups. In the first KC session, the infant temperature at 60 minutes was 36.79°C (0.43) in lateral KC position, and 36.78°C (0.38) in prone KC position (p = .022). In lateral KC position, 7.69% (2) of the children who, according to the cranial ultrasound performed before the first session, had no haemorrhage presented with intraventricular haemorrhage after the first session. In prone KC position, new haemorrhages appeared after the first session in 29.17% (7) (p = .08). CONCLUSIONS The lateral KC position is an alternative to the conventional prone KC position and maintains normothermia in infants under 28 weeks gestational age. RELEVANCE TO CLINICAL PRACTICE Extremely preterm infants are candidates for KC. Lateral KC position is an evidence-based best practice that can be applied to preterm infants under 28 weeks GA. This evidence is particularly useful in performing umbilical catheterization on these patients.

Abstract
AIM(S) To identify, synthesise and map systematic reviews of the effectiveness of nursing interventions undertaken in a neonatal intensive care unit or special care nursery. DESIGN This scoping review was conducted according to the JBI scoping review framework. METHODS Review included systematic reviews that evaluated any nurse-initiated interventions that were undertaken in an NICU or SCN setting. Studies that reported one or more positive outcomes related to the nursing interventions were only considered for this review. Each outcome for nursing interventions was rated a 'certainty (quality) of evidence' according to the Grading of Recommendations, Assessment, Development and Evaluations criteria. DATA SOURCES Systematic reviews were sourced from the Cochrane Database of Systematic Reviews and Joanna Briggs Institute Evidence Synthesis for reviews published until February 2023. RESULTS A total of 428 articles were identified; following screening, 81 reviews underwent full-text screening, and 34 articles met the inclusion criteria and were included in this review. Multiple nursing interventions reporting positive outcomes were identified and were grouped into seven categories. Respiratory 7/34 (20%) and Nutrition 8/34 (23%) outcomes were the most reported categories. Developmental care was the next most reported category 5/34 (15%) followed by Thermoregulation, 5/34 (15%) Jaundice 4/34 (12%), Pain 4/34 (12%) and Infection 1/34 (3%). CONCLUSIONS This review has identified nursing interventions that have a direct positive impact on neonatal outcomes. However, further applied research is needed to transfer this empirical knowledge into clinical practice. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE Implementing up-to-date evidence on effective nursing interventions has the potential to significantly improving neonatal outcomes. PATIENT OR PUBLIC CONTRIBUTION No patient or public involvement in this scoping review.

Abstract
Abnormal temperature in preterm infants is associated with increased morbidity and mortality. Infants born prematurely are at risk of abnormal temperature immediately after birth in the delivery room (DR). The World Health Organization (WHO) recommends that the temperature of newly born infants is maintained between 36.5-37.5oC after birth. When caring for very preterm infants, the International Liaison Committee on Resuscitation (ILCOR) recommends using a combination of interventions to prevent heat loss. While hypothermia remains prevalent, efforts to prevent it have increased the incidence of hyperthermia, which may also be harmful. Delayed cord clamping (DCC) for preterm infants has been recommended by ILCOR since 2015. Little is known about the effect of timing of DCC on temperature, nor have there been specific recommendations for thermal care before DCC. This review article focuses on the current evidence and recommendations for thermal care in the DR, and considers thermoregulation in the context of emerging interventions and future research directions. IMPACT: Abnormal temperature is common amongst very preterm infants after birth, and is an independent risk factor for mortality. The current guidelines recommend a combination of interventions to prevent heat loss after birth. Despite this, abnormal temperature is still a problem, across all climates and economies. New and emerging delivery room practice (i.e., delayed cord clamping, mobile resuscitation trolleys, early skin to skin care) may have an effect on infant temperature. This article reviews the current evidence and recommendations, and considers future research directions.

Abstract
OBJECTIVE Hypothermia on admission to the neonatal intensive care unit (NICU) is associated with an increased risk of death in preterm infants. There are currently no evidence-based recommendations for thermal care before cord clamping (CC). We wished to determine whether placing very preterm infants in a polyethylene bag (PB) before CC, compared with after CC, results in more infants with a temperature in the normal range on NICU admission. DESIGN Randomised controlled trial. SETTING Tertiary maternity hospital. PATIENTS Inborn infants<32 weeks' gestational age (GA). INTERVENTIONS Infants were randomly assigned to have a PB placed before or after CC. MAIN OUTCOME Rectal temperature within the normal range (36.5°C-37.5°C) on NICU admission. RESULTS Between July 2020 and September 2022, 198/220 (90%) eligible infants were enrolled in this study; 99 (44 (44%) girls) were randomly assigned to BEFORE and 99 (53 (54%) girls) to AFTER. Median (IQR) GA 29 (27-31) vs 29 (27-31) weeks, mean (SD) birth weight 1206 (429) vs 1138 (419) g, respectively. The proportion of infants who had normal temperature on NICU admission did not differ between the groups (BEFORE 54/99 (55%) vs AFTER 55/98 (56%), p 0.824). The proportion of infants with a temperature outside of the normal range was similar between the groups; hypothermia (BEFORE 34/99 (34%) vs AFTER 33/98 (34%), hyperthermia (BEFORE 10/99 (10%) vs AFTER 10/98 (10%)). CONCLUSIONS Placing a PB before CC did not increase the proportion of preterm infants with normal temperature on NICU admission. A large proportion of preterm infants had abnormal temperature. Further studies on thermoregulation before CC are needed. TRIAL REGISTRATION NUMBER NCT04463511.

Preclinical validation of NeoWarm, a low-cost infant warmer and carrier device, to ameliorate induced hypothermia in newborn piglets as models for human neonates. Front Pediatr 2024; 12:1378008. [PMID: 38633325 PMCID: PMC11021732 DOI: 10.3389/fped.2024.1378008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 03/18/2024] [Indexed: 04/19/2024] Open
Abstract
Introduction Approximately 1.5 million neonatal deaths occur among premature and small (low birthweight or small-for gestational age) neonates annually, with a disproportionate amount of this mortality occurring in low- and middle-income countries (LMICs). Hypothermia, the inability of newborns to regulate their body temperature, is common among prematurely born and small babies, and often underlies high rates of mortality in this population. In high-resource settings, incubators and radiant warmers are the gold standard for hypothermia, but this equipment is often scarce in LMICs. Kangaroo Mother Care/Skin-to-skin care (KMC/STS) is an evidence-based intervention that has been targeted for scale-up among premature and small neonates. However, KMC/STS requires hours of daily contact between a neonate and an able adult caregiver, leaving little time for the caregiver to care for themselves. To address this, we created a novel self-warming biomedical device, NeoWarm, to augment KMC/STS. The present study aimed to validate the safety and efficacy of NeoWarm. Methods Sixteen, 0-to-5-day-old piglets were used as an animal model due to similarities in their thermoregulatory capabilities, circulatory systems, and approximate skin composition to human neonates. The piglets were placed in an engineered cooling box to drop their core temperature below 36.5°C, the World Health Organizations definition of hypothermia for human neonates. The piglets were then warmed in NeoWarm (n = 6) or placed in the ambient 17.8°C ± 0.6°C lab environment (n = 5) as a control to assess the efficacy of NeoWarm in regulating their core body temperature. Results All 6 piglets placed in NeoWarm recovered from hypothermia, while none of the 5 piglets in the ambient environment recovered. The piglets warmed in NeoWarm reached a significantly higher core body temperature (39.2°C ± 0.4°C, n = 6) than the piglets that were warmed in the ambient environment (37.9°C ± 0.4°C, n = 5) (p < 0.001). No piglet in the NeoWarm group suffered signs of burns or skin abrasions. Discussion Our results in this pilot study indicate that NeoWarm can safely and effectively warm hypothermic piglets to a normal core body temperature and, with additional validation, shows promise for potential use among human premature and small neonates.

Cheng K, Zhu H, Zhou Z, Chen W, Yang A. Value of brain tissue oxygen saturation in neonatal respiratory distress syndrome: a clinical study. Eur J Transl Myol 2024; 34:11863. [PMID: 38372644 PMCID: PMC11017171 DOI: 10.4081/ejtm.2024.11863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Accepted: 10/02/2023] [Indexed: 02/20/2024] Open
Abstract
Neonatal respiratory distress syndrome (NRDS) is one of the major causes of pre-term mortality and morbidity among very-low-birth-weight infants (VLBWI) in low- and middle-income countries (LMIC). Some of the neonates pass away despite admission and care in intensive care units (ICUs). The present clinical trial seeks the application value of elevating oxygen saturation in the brain cells of pre-term neonates born with NRDS. Near-infrared spectroscopy (NIRS) was used to monitor the neonates' microscopic cerebral oxygenation levels do determine hemoglobin concentration in brain tissues, whereas the pulse oximetry was used to measure oxygenation levels among the patients. In statistical analyses, the Analysis of Variance (ANOVA), and descriptive statistics was deployed in the Jupyter Notebook environment using Python language. High saturation of oxygen in the brain tissues result in important biological and physiological processes, including enhanced oxygen supply to cells, reduced severity of NRDS, and balancing oxygen demand and supply. The correlations of oxygen saturation with systemic saturation of oxygen, the saturation of oxygen in brain tissues, the association between brain-specific and systemic saturation, and the impact of these outcomes on clinical practices were deliberated. Also, the pH gas values, the saturation of oxygen in neonates' brain tissues, metabolic acidosis, the effect of acid-base balance and cerebral oxygen supply, and the oxygenation of brain tissues and the pH values emerged as important variables of oxygenation of brain tissues in pre-term neonates. Oxygen saturation in brain cells influence vital physiological and biological processes. Balancing acid-base saturation or levels is needed despite the challenging achievement. Oxygenation of brain tissues improve the brain's overall functioning.

Transferring an extremely premature infant to an extra-uterine life support system: a prospective view on the obstetric procedure. Front Pediatr 2024; 12:1360111. [PMID: 38425664 PMCID: PMC10902175 DOI: 10.3389/fped.2024.1360111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 02/02/2024] [Indexed: 03/02/2024] Open
Abstract
To improve care for extremely premature infants, the development of an extrauterine environment for newborn development is being researched, known as Artificial Placenta and Artificial Womb (APAW) technology. APAW facilitates extended development in a liquid-filled incubator with oxygen and nutrient supply through an oxygenator connected to the umbilical vessels. This setup is intended to provide the optimal environment for further development, allowing further lung maturation by delaying gas exposure to oxygen. This innovative treatment necessitates interventions in obstetric procedures to transfer an infant from the native to an artificial womb, while preventing fetal-to-neonatal transition. In this narrative review we analyze relevant fetal physiology literature, provide an overview of insights from APAW studies, and identify considerations for the obstetric procedure from the native uterus to an APAW system. Lastly, this review provides suggestions to improve sterility, fetal and maternal well-being, and the prevention of neonatal transition.

Abstract
BACKGROUND Very preterm infants (less than 32 weeks gestational age) experience acute morbidity during their stay in a neonatal intensive care unit. Because of their prematurity and frequent laboratory testing, they experience anemia, requiring correction with packed red blood cell (PRBC) transfusion(s). PRBC transfusions have been linked to neonatal morbidity, such as necrotizing enterocolitis, but never signs and symptoms of physiological stability. OBJECTIVE The secondary data analysis aimed to examine very preterm infants' physiological stability before, during, and after PRBC transfusions. METHODS A within-case, mixed-methods design was used in a secondary data analysis for 16 transfusion cases from 13 very preterm infants. RESULTS The findings showed very preterm infants with physiological variables falling within defined limits based on gestational age during the transfusion. Two contrasting case exemplars will be presented. DISCUSSION PRBC transfusions are necessary and prevent morbidity in very preterm infants. Observing instability during transfusions and prospectively studying hypothermia, cardiac instability, and thermal gradients is essential to design interventions to decrease morbidity associated with PRBC transfusions.

Abstract
Background Admission hypothermia is still an underappreciated major challenge for new-born survival in low-resource settings. The WHO recommends skin-to-skin contact as the simplest and safest way for maintaining the body temperature even during transportation. Quality improvement initiatives for hospitalised new-borns have shown benefits like a reduction in neonatal morbidity and mortality. This study was undertaken in a resource-constrained public hospital in southern India with an aim to reduce neonatal hypothermia at admission to <20%. Method It was a prospective, quality improvement study undertaken over 20 weeks. All neonates born in the selected delivery room (DR), requiring transportation to the neonatal intensive care unit, were included. The primary outcome indicators were the mean axillary temperature of neonates measured upon arrival at the neonatal intensive care unit and the percentage of neonates with hypothermia at admission. Improving the thermoregulatory practices and ambient DR temperature to >25˚C, transportation by the kangaroo method, and a portable infant warmer (PIW) were implemented in three successive Plan-Do-Study-Act (PDSA) cycles. Result In the third PDSA cycle, the mean admission temperature (36.51˚C ±0.82) was significantly (p<0.0001) higher when compared with the baseline phase (35.41˚C ±1.09), and there was a significant (p<0.001) reduction in hypothermia (33.33%). The aim was achieved in the last two weeks of the third cycle with a reduction in hypothermia to 17.6%. Conclusion Implementation of appropriate thermoregulatory practices and low-cost strategies like the kangaroo method and PIW using quality improvement methodology significantly reduced admission hypothermia.

Abstract
BACKGROUND Are thermoregulation and golden hour practices in extremely preterm (EP) infants comparable across the world? This study aims to describe these practices for EP infants based on the neonatal intensive care unit's (NICUs) geographic region, country's income status and the lowest gestational age (GA) of infants resuscitated. METHODS The Director of each NICU was requested to complete the e-questionnaire between February 2019 and August 2021. RESULTS We received 848 responses, from all geographic regions and resource settings. Variations in most thermoregulation and golden hour practices were observed. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission, and having local protocols were the most consistent practices (>75%). The odds for the following practices differed in NICUs resuscitating infants from 22 to 23 weeks GA compared to those resuscitating from 24 to 25 weeks: respiratory support during resuscitation and transport, use of polyethylene plastic wrap and servo-control mode, commencing ambient humidity >80% and presence of local protocols. CONCLUSION Evidence-based practices on thermoregulation and golden hour stabilisation differed based on the unit's region, country's income status and the lowest GA of infants resuscitated. Future efforts should address reducing variation in practice and aligning practices with international guidelines. IMPACT A wide variation in thermoregulation and golden hour practices exists depending on the income status, geographic region and lowest gestation age of infants resuscitated. Using a polyethylene plastic wrap, commencing humidity within 60 min of admission and having local protocols were the most consistent practices. This study provides a comprehensive description of thermoregulation and golden hour practices to allow a global comparison in the delivery of best evidence-based practice. The findings of this survey highlight a need for reducing variation in practice and aligning practices with international guidelines for a comparable health care delivery.

Abstract
Hypothermia occurs frequently among clinically unstable neonates who are not suitable to place in skin-to-skin care. This study aims to explore the existing evidence on the effectiveness, usability, and affordability of neonatal warming devices when skin-to-skin care is not feasible in low-resource settings. To explore existing data, we searched for (1) systematic reviews as well as randomised and quasi-randomised controlled trials comparing the effectiveness of radiant warmers, conductive warmers, or incubators among neonates, (2) neonatal thermal care guidelines for the use of warming devices in low-resource settings and (3) technical specification and resource requirement of warming devices which are available in the market and certified medical device by the US Food and Drug Administration or with a CE marking. Seven studies met the inclusion criteria, two were systematic reviews comparing radiant warmers vs. incubators and heated water-filled mattresses vs. incubators, and five were randomised controlled trials comparing conductive thermal mattresses with phase-change materials vs. radiant warmers and low-cost cardboard incubator vs. standard incubator. There was no significant difference in effectiveness between devices except radiant warmers caused a statistically significant increase in insensible water loss. Seven guidelines covering the use of neonatal warming devices show no consensus about the choice of warming methods for clinically unstable neonates. The main warming devices currently available and intended for low-resource settings are radiant warmers, incubators, and conductive warmers with advantages and limitations in terms of characteristics and resource requirements. Some devices require consumables which need to be considered when making a purchase decision. As effectiveness is comparable between devices, specific requirements according to patients' characteristics, technical specification, and context suitability must play a primary role in the selection and purchasing decision of warming devices. In the delivery room, a radiant warmer allows fast access during a short period and will benefit numerous neonates. In the neonatal unit, warming mattresses are low-cost, effective, and low-electricity consumption devices. Finally, incubators are required for very premature infants to control insensible water losses, mainly during the first one to two weeks of life, mostly in referral centres.

Abstract
OBJECTIVES Neonatal sepsis is one of the leading causes of neonatal deaths in neonatal intensive care units. Hence, it is essential to review the evidence from systematic reviews on interventions for reducing late-onset sepsis (LOS) in neonates. METHODS PubMed and the Cochrane Central were searched from inception through August 2020 without any language restriction. Cochrane reviews of randomized clinical trials (RCTs) assessing any intervention in the neonatal period and including one or more RCTs reporting LOS. Two authors independently performed screening, data extraction, assessed the quality of evidence using Cochrane Grading of Recommendations Assessment, Development and Evaluation, and assessed the quality of reviews using a measurement tool to assess of multiple systematic reviews 2 tool. RESULTS A total of 101 high-quality Cochrane reviews involving 612 RCTs and 193,713 neonates, evaluating 141 interventions were included. High-quality evidence showed a reduction in any or culture-proven LOS using antibiotic lock therapy for neonates with central venous catheters (CVC). Moderate-quality evidence showed a decrease in any LOS with antibiotic prophylaxis or vancomycin prophylaxis for neonates with CVC, chlorhexidine for skin or cord care, and kangaroo care for low birth weight babies. Similarly, moderate-quality evidence showed reduced culture-proven LOS with intravenous immunoglobulin prophylaxis for preterm infants and probiotic supplementation for very low birth weight (VLBW) infants. Lastly, moderate-quality evidence showed a reduction in fungal LOS with the use of systemic antifungal prophylaxis in VLBW infants. CONCLUSIONS The overview summarizes the evidence from the Cochrane reviews assessing interventions for reducing LOS in neonates, and can be utilized by clinicians, researchers, policymakers, and consumers for decision-making and translating evidence into clinical practice.

Abstract
The objective of the study was to determine if using the hypothermia-detecting bracelet (named BEMPU) improves the duration of Kangaroo Mother Care (KMC) at home by one hour. This parallel-group randomized controlled trial was conducted at a step-down nursery of a teaching hospital. Neonates between 1000 and 2000 g were randomized to BEMPU and control groups at the time of discharge. BEMPU was applied at the wrist of each newborn in the BEMPU (intervention) group. Parents were advised to keep the BEMPU in place till 4 weeks post-discharge. The BEMPU generates a beep sound as an alarm when a newborn's temperature drops below 36.5 °C. Parents in both groups were trained to provide KMC at home. Parents in the BEMPU group received the "KMC chart" and "BEMPU beep chart," while the control group received the "KMC chart" only. In the "KMC chart," parents entered information about KMC hours on a real-time basis, and in the "BEMPU beep chart," they entered information about alarm beeps from BEMPU on a real-time basis till 4 weeks post-discharge. Independent samples t-test was used to compare mean KMC hours between the two groups. A total of 128 neonates participated in the study (64 in BEMPU and 64 in Control groups). The mean(SD) gestational age for the BEMPU group was 34.04(2.84) weeks vs 34.75(2.70) weeks for the control group. In BEMPU group, mean(SD) daily time spent doing KMC was significantly higher in 1st week [4.78(2.93) vs. 3.22(2.44) h, p = 0.003], in 2nd week [4.52(3.43) vs. 2.84(2.95) h, p = 0.008], in 3rd week [4.23(3.71) vs. 2.30(2.70) h, p = 0.003], in 4th week [3.72(3.30) vs. 1.95(2.65) h, p = 0.003] as compared to control group. BEMPU improved the daily duration of KMC hours at home compared to the control group over four weeks.

Abstract
Purpose Kangaroo care is a complementary humanistic intervention based on a family-centered care model. This study investigated the effects of a locally contextualized, structured kangaroo care education program on weight gain, breastfeeding rate and length of hospitalization for premature infants. Patients and Methods This longitudinal quasi-experimental study with pre- and post-intervention design involved 96 infants born between 28 and 37 weeks of gestation for three months, and was carried out at a neonatal intensive care unit in Malaysia. The experimental group received a structured education program and careful monitoring of their kangaroo care practices, while the control group received routine care without a structured education program. The institutional review board approved the study design and registered at ClinicalTrials.gov (NCT04926402). Results The kangaroo care hours performed by mothers at baseline in the experimental and control group was 4.12 and 0.55 hours per week, respectively. At three months post-discharge, the experimental group had significantly higher weight gain, higher breastfeeding rates and shorter lengths of hospitalization than the control group. Conclusion A locally contextualized and structured kangaroo care education program is effective in the performance of kangaroo care. One hour per day of kangaroo care is positively associated with an extended period of breastfeeding, improved weight gain and shorter hospitalization of premature infants.

Maintaining normal temperature immediately after birth in late preterm and term infants: A systematic review and meta-analysis. Resuscitation 2022; 180:81-98. [PMID: 36174764 DOI: 10.1016/j.resuscitation.2022.09.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Revised: 09/15/2022] [Accepted: 09/17/2022] [Indexed: 11/22/2022]
Abstract
AIM Prevention of hypothermia after birth is a global problem in late preterm and term neonates. The aim of this systematic review and meta-analysis was to evaluate delivery room strategies to maintain normothermia and improve survival in late preterm and term neonates (≥34 weeks' gestation). METHODS Medline, Embase, CINAHL, CENTRAL and international clinical trial registries were searched. Randomized controlled trials (RCTs), quasi-RCTs and observational studies were eligible for inclusion. Risk of bias for each study and GRADE certainty of evidence for each outcome were assessed. RESULTS 25 RCTs and 10 non-RCTs were included. Room temperature of 23 °C compared to 20 °C improved normothermia [Risk Ratio (RR), 95% Confidence Interval (CI): 1.26, 1.11-1.42)] and body temperature [Mean Difference (MD), 95% CI: 0.30 °C, 0.23-0.37 °C), and decreased moderate hypothermia (RR, 95% CI: 0.26, 0.16-0.42). Skin to skin care (SSC) compared to no SSC increased body temperature (MD, 95% CI: 0.32, 0.10-0.52), reduced hypoglycemia (RR, 95% CI: 0.16, 0.05-0.53) and hospital admission (RR, 95% CI: 0.34, 0.14-0.83). Though plastic bag or wrap (PBW) alone or when combined with SSC compared to SSC alone improved temperatures, the risk-benefit balance is uncertain. Clinical benefit or harm could not be excluded for the primary outcome of survival for any of the interventions. Certainty of evidence was low to very low for all outcomes. CONCLUSIONS Room temperature of 23 °C and SSC soon after birth may prevent hypothermia in late preterm and term neonates. Though PBW may be an effective adjunct intervention, the risk-benefit balance needs further investigation.

Mild controlled hypothermia for necrotizing enterocolitis treatment to preterm neonates: low technology technique description and safety analysis. Eur J Pediatr 2022; 181:3511-3521. [PMID: 35840777 DOI: 10.1007/s00431-022-04558-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 06/22/2022] [Accepted: 07/04/2022] [Indexed: 11/03/2022]
Abstract
UNLABELLED We performed a quality improvement project to necrotizing enterocolitis (NEC) and published our results about the initiative in 2021. However, aspects on the safety of the cooling and how to do therapeutic hypothermia with low technology to preterm infants are not described in this previous reporter. Thus, we aim to describe the steps and management to apply hypothermia in preterm infants using low technology and present the safety aspects regarding the initiative. We performed a quality improvement project to NEC in a reference hospital for neonatology (intensive care unit). Forty-three preterm infants with NEC (modified Bell's stage II/III) were included: 19 in the control group (2015-2018) and 24 in the hypothermic group (2018-2020). The control group received standard treatments. The hypothermia group received standard treatment and underwent passive cooling (35.5 °C, used for 48 h after NEC diagnosis). We reported cooling safety to NEC, assessing hematological and gasometrical parameters, coagulation disorders, clinical instability, and neurological disorders. We described how to perform cooling to preterm infants using incubators' servo-control and the occurrence and management of dysthermia during the cooling. We turn-off the incubator and used the esophageal probe to monitor the temperature every 15 min; if the temperature dropped, the incubator was turned on with a rewarming speed of 0.5 °C/h. The participants' average weights and gestational ages were 1186 g and 32 weeks, respectively. There were no differences among hematological indices, serum parameters (sodium, potassium, creatinine, lactate, and bicarbonate), pH, pCO2, and pO2/FiO2 between the groups during treatment and after rewarming. We did not observe dysthermia, bradycardia, hemodynamic instability, apnea, seizure, bleeding, peri-intraventricular hemorrhage, or any alterations in ventilatory parameters due to the cooling technique in preterm babies. This simple technique was performed without intercurrences through a rigorous team evaluation, with a target cooling speed of 0.5 °C/h. The target temperature was successfully reached between the second and third hours of life with the incubator control in 21 children; ice bags were used in only three cases. The temperature was maintained at the expected level during the programmed cooling period. CONCLUSION Mild controlled hypothermia for preterm infants with NEC is safe. The cooling of preterm infants could be performed through passive methods, using the servo-control of the incubators for temperature management. WHAT IS KNOWN • Mild controlled hypothermia to NEC treatment is feasible and associated with a decrease in NEC surgery, short bowel, and death. • Mild controlled hypothermia to preterm is feasible and can be performed through low technology and passive cooling. WHAT IS NEW • Mild controlled hypothermia to preterm is safe and does not associate with safety adverse effects during and after the cooling. • Preterm infants can be cooled through passive methods by just using the servo control of the incubator, presenting acceptable temperature variance, without dysthermia, achieving and remaining at the target temperature with a proper cooling speed. Mild controlled temperature for preterm infants does not need an additional cooling device.

Abstract
Background In January 2019, a new device called the Amplatzer Piccolo Occluder was approved by the US Food and Drug Administration for percutaneous closure of patent ductus arteriosus in infants weighing more than 700 g and of postnatal age more than 3 days. Premature low-weight infants are predisposed to hypothermia when transported outside of the thermo-neutral environment. At our institution, 90% of extremely preterm low-weight infants developed transient moderate hypothermia in the cardiac catheterisation suite. Methods We conducted a study testing multiple hypotheses aimed at preventing hypothermia in the cardiac catheterisation suite. Interventions included increasing ambient room temperature, reducing exposure to cold environment and reducing overall time spent in the remote location. The primary outcome was the proportion of patients who developed transient hypothermia at the start of the procedure in the cardiac catheterisation suite. The secondary measures included mean core body temperature at four different instances, as well as anaesthesia time, procedure time and radiation exposure. Results During the study period, 10 patients were enrolled in each group. The postintervention group saw a reduction in transient hypothermia from 90% to 40% (absolute risk reduction 50%, p=0.02). Data analysis showed an improvement in mean core body temperature (35.4°C vs 36.4°C, p<0.01) as well as a smaller percentage drop in temperature (4% vs 1.3%, p<0.01) between the two groups, both of which were statistically significant. The anaesthesia time, procedure time and radiation exposure reduced between the two groups. Conclusion The application of the interventions reduced hypothermia in this high-risk population. The implementation of a protocol with collaboration of a multidisciplinary team is indispensable in providing optimal care to extremely preterm infants.

Abstract
Thermoregulation is an essential component to the stability and long-term outcomes of newborns and critically-ill neonates. A thermoneutral environment (TNE) is an environment in which a neonate maintains a normal body temperature while minimizing energy expenditure and oxygen consumption. Neonates who experience thermal stability within a TNE demonstrate enhanced growth, decreased respiratory support, decreased oxygen requirements, increased glucose stability, reduced mortality, and reduced morbidities associated with hyperthermia and hypothermia. Heat exchange occurs between the neonate and surrounding environment through four mechanisms: evaporation, conduction, convection, and radiation. By recognizing the methods by which heat is lost or gained, the neonatal provider can prevent adverse conditions related to abnormal thermal control and support a thermoneutral neonatal environment.

Abstract
BACKGROUND Lack of appropriate temperature management has been associated with significant adverse outcomes in preterm and low birthweight neonates. There is a lack of similar investigations in the late preterm (340-366) and term (≥370) neonate population. Our aim was to identify key risk factors as well as clinical outcomes associated with hypothermia in this population. METHODS A retrospective chart review was conducted at the Ottawa Hospital including all eligible infants ≥340 weeks' gestation over a one-month period in November 2020. Infant, maternal, and delivery room variables were collected, including prematurity, maternal temperature, delivery mode, birthweight, and premature rupture of membranes, as well as clinical outcomes such as NICU/SCN admission and length of stay. Regression models were generated, adjusted for covariates, and stepwise regression was performed. RESULTS Four hundred forty infants were included in the analysis; 26.8% (118/440) were hypothermic within 6 hours of delivery. In the multivariable analysis, prematurity, low 5 minute Apgar score (< 7) or need for resuscitation, maternal hypertension, and absence of premature rupture of membranes > 18 hours or suspected maternal infection were significantly associated with hypothermia within 6 hours of delivery (p < 0.05). Multivariable analysis of clinical outcomes demonstrated a significant association between hypothermia within 6 hours of delivery and NICU/SCN admission (OR = 2.87; 95% CI 1.36, 6.04), need for respiratory support or diagnosis of respiratory distress syndrome (OR = 3.94; 95% CI 1.55, 10.50), and length of stay (exp(β) = 1.20; 95% bootstrap CI 1.04, 1.37). CONCLUSIONS Our results suggest there are similar factors associated with hypothermia in our study population of infants born at ≥340 weeks' gestation compared to prior studies in preterm and low-birthweight infants. Furthermore, hypothermia is associated with higher risk of adverse outcomes, which highlights the need to prevent hypothermia in all newborns.

Abstract
BACKGROUND Postnatal Care (PNC) is one of the healthcare-packages in the continuum of care for mothers and children that needs to be in place to reduce global maternal and perinatal mortality and morbidity. We sought to identify the essential components of PNC and develop signal functions to reflect these which can be used for the monitoring and evaluation of availability and quality of PNC. METHODS Systematic review of the literature using MESH headings for databases (Cinahl, Cochrane, Global Health, Medline, PubMed, and Web of Science). Papers and reports on content of PNC published from 2000-2020 were included. Narrative synthesis of data and development of signal function through 7 consensus-building workshops with 184 stakeholders. RESULTS Forty-Eight papers and reports are included in the systematic review from which 22 essential components of PNC were extracted and used to develop 14 signal functions. Signal functions are used in obstetrics to denote a list of interventions that address major causes of maternal and perinatal morbidity or mortality. For each signal function we identified the equipment, medication and consumables required for implementation. The prevention and management of infectious diseases (malaria, HIV, tuberculosis) are considered essential components of routine PNC depending on population disease burden or whether the population is considered at risk. Screening and management of pre-eclampsia, maternal anaemia and mental health are recommended universally. Promotion of and support of exclusive breastfeeding and uptake of a modern contraceptive method are also considered essential components of PNC. For the new-born baby, cord care, monitoring of growth and development, screening for congenital disease and commencing vaccinations are considered essential signal functions. Screening for gender-based violence (GBV) including intimate partner- violence (IPV) is recommended when counselling can be provided and/or a referral pathway is in place. Debriefing following birth (complicated or un-complicated) was agreed through consensus-building as an important component of PNC. CONCLUSIONS Signal functions were developed which can be used for monitoring and evaluation of content and quality of PNC. Country adaptation and validation is recommended and further work is needed to examine if the proposed signal functions can serve as a useful monitoring and evaluation tool. TRIAL REGISTRATION The systematic review protocol was registered: PROSPERO 2018 CRD42018107054 .

Abstract
AIM Thermal instability is harmful on the newborn infant. We sought to draw up practical guidelines on maintaining homeothermy alongside skin-to-skin contact. METHODS A systematic analysis of the literature identified relevant studies between 2000 and 2021 in the PubMed database. Selected publications were evaluated, and their level of evidence were graded, in order to underpin the development of clinical guidelines. RESULTS We identified 7 meta-analyses and 64 clinical studies with a focus on newborn infants homeothermy. Skin-to-skin contact is the easiest and most rapidly implementable method to prevent body heat loss. Alongside skin-to-skin contact, monitoring the newborn infant's body temperature with a target of 37.0°C is essential. For newborn infants <32 weeks of gestation, a skullcap and a polyethylene bag should be used in the delivery room or during transport. To limit water loss, inhaled gases humidification and warming is recommended, and preterm infants weighing less than 1600 g should be nursed in a closed, convective incubator. With regard to incubators, there are no clear benefits for single vs. double-wall incubators as well as for air vs. skin servo control. CONCLUSION Alongside skin-to-skin contact, a bundle of practical guidelines could improve the maintenance of homeothermy in the newborn infant.

Abstract
IMPORTANCE Bronchopulmonary dysplasia (BPD) has multifactorial etiology and long-term adverse consequences. An umbrella review enables the evaluation of multiple proposed interventions for the prevention of BPD. OBJECTIVE To summarize and assess the certainty of evidence of interventions proposed to decrease the risk of BPD from published systematic reviews. DATA SOURCES MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, and Web of Science were searched from inception until November 9, 2020. STUDY SELECTION Meta-analyses of randomized clinical trials comparing interventions in preterm neonates that included BPD as an outcome. DATA EXTRACTION AND SYNTHESIS Data extraction was performed in duplicate. Quality of systematic reviews was evaluated using Assessment of Multiple Systematic Reviews version 2, and certainty of evidence was assessed using Grading of Recommendation, Assessment, Development, and Evaluation. MAIN OUTCOMES AND MEASURES (1) BPD or mortality at 36 weeks' postmenstrual age (PMA) and (2) BPD at 36 weeks' PMA. RESULTS A total of 154 systematic reviews evaluating 251 comparisons were included, of which 110 (71.4%) were high-quality systematic reviews. High certainty of evidence from high-quality systematic reviews indicated that delivery room continuous positive airway pressure compared with intubation with or without routine surfactant (relative risk [RR], 0.80 [95% CI, 0.68-0.94]), early selective surfactant compared with delayed selective surfactant (RR, 0.83 [95% CI, 0.75-0.91]), early inhaled corticosteroids (RR, 0.86 [95% CI, 0.75-0.99]), early systemic hydrocortisone (RR, 0.90 [95% CI, 0.82-0.99]), avoiding endotracheal tube placement with delivery room continuous positive airway pressure and use of less invasive surfactant administration (RR, 0.90 [95% CI, 0.82-0.99]), and volume-targeted compared with pressure-limited ventilation (RR, 0.73 [95% CI, 0.59-0.89]) were associated with decreased risk of BPD or mortality at 36 weeks' PMA. Moderate to high certainty of evidence showed that inhaled nitric oxide, lower saturation targets (85%-89%), and vitamin A supplementation are associated with decreased risk of BPD at 36 weeks' PMA but not the competing outcome of BPD or mortality, indicating they may be associated with increased mortality. CONCLUSIONS AND RELEVANCE A multipronged approach of delivery room continuous positive airway pressure, early selective surfactant administration with less invasive surfactant administration, early hydrocortisone prophylaxis in high-risk neonates, inhaled corticosteroids, and volume-targeted ventilation for preterm neonates requiring invasive ventilation may decrease the combined risk of BPD or mortality at 36 weeks' PMA.

Ending Neonatal Deaths From Hypothermia in Sub-Saharan Africa: Call for Essential Technologies Tailored to the Context. Front Public Health 2022; 10:851739.

Abstract
Neonatal death represents a major burden in Sub-Saharan Africa (SSA), where the main conditions triggering mortality, such as prematurity, labor complications, infections, and respiratory distress syndrome, are frequently worsened by hypothermia, which dramatically scales up the risk of death. In SSA, the lack of awareness on the procedures to prevent hypothermia and the shortage of essential infant devices to treat it are hampering the reduction of neonatal deaths associated to hypothermia. Here, we offer a snapshot on the current available medical solutions to prevent and treat hypothermia in SSA, with a focus on Kenya. We aim to provide a picture that underlines the essential need for infant incubators in SSA. Specifically, given the inappropriateness of the incubators currently on the market, we point out the need for reinterpretation of research in the field, calling for technology-based solutions tailored to the SSA context, the need, and the end-user.

Rosa-Mangeret F, Benski AC, Golaz A, Zala PZ, Kyokan M, Wagner N, Muhe LM, Pfister RE. 2.5 Million Annual Deaths-Are Neonates in Low- and Middle-Income Countries Too Small to Be Seen? A Bottom-Up Overview on Neonatal Morbi-Mortality. Trop Med Infect Dis 2022; 7:64. [PMID: 35622691 PMCID: PMC9148074 DOI: 10.3390/tropicalmed7050064] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Revised: 03/25/2022] [Accepted: 04/11/2022] [Indexed: 12/29/2022] Open
Abstract
(1) Background: Every year, 2.5 million neonates die, mostly in low- and middle-income countries (LMIC), in total disregard of their fundamental human rights. Many of these deaths are preventable. For decades, the leading causes of neonatal mortality (prematurity, perinatal hypoxia, and infection) have been known, so why does neonatal mortality fail to diminish effectively? A bottom-up understanding of neonatal morbi-mortality and neonatal rights is essential to achieve adequate progress, and so is increased visibility. (2) Methods: We performed an overview on the leading causes of neonatal morbi-mortality and analyzed the key interventions to reduce it with a bottom-up approach: from the clinician in the field to the policy maker. (3) Results and Conclusions: Overall, more than half of neonatal deaths in LMIC are avoidable through established and well-known cost-effective interventions, good quality antenatal and intrapartum care, neonatal resuscitation, thermal care, nasal CPAP, infection control and prevention, and antibiotic stewardship. Implementing these requires education and training, particularly at the bottom of the healthcare pyramid, and advocacy at the highest levels of government for health policies supporting better newborn care. Moreover, to plan and follow interventions, better-quality data are paramount. For healthcare developments and improvement, neonates must be acknowledged as humans entitled to rights and freedoms, as stipulated by international law. Most importantly, they deserve more respectful care.

Abstract
INTRODUCTION PEA POD™ air displacement plethysmography quickly and noninvasively estimates neonatal body fat percentage (BF%). Low PEA POD™ BF% predicts morbidity better than classification as small-for-gestational-age (SGA; <10th centile), but PEA PODs are not widely available. We examined whether skinfold measurements could effectively identify neonates at risk; comparing skinfold BF%, PEA POD™ BF% and birthweight centiles' prediction of hypothermia - a marker of reduced in utero nutrition. METHODS Neonates had customized birthweight centiles calculated, and BF% prospectively estimated by: (i) triceps and subscapular skinfolds using sex-specific equations; and (ii) PEA POD™. Medical record review identified hypothermic (<36.5 °C) episodes. RESULTS 42/149 (28%) neonates had hypothermia. Skinfold BF%, with an area under the curve (AUC) of 0.66, predicted hypothermia as well as PEA POD™ BF% (AUC = 0.62) and birthweight centile (AUC = 0.61). Birthweight <10th centile demonstrated 11.9% sensitivity, 38.5% positive predictive value (PPV) and 92.5% specificity for hypothermia. At equal specificity, skinfold and PEA POD™ BF% more than doubled sensitivity (26.2%) and PPV increased to 57.9%. CONCLUSION Neonatal BF% performs better to predict neonatal hypothermia than birthweight centile, and may be a better measure of true fetal growth restriction. Estimation of neonatal BF% by skinfold measurements is an inexpensive alternative to PEA POD™.

Abstract
BACKGROUND Thermal management of the newborn at birth remains an actual challenge. This systematic review aimed to summarize current evidence on the use of thermal servo-controlled systems during stabilization of preterm and VLBW infants immediately at birth. METHODS A comprehensive search was conducted including MEDLINE/Pubmed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database through December 2021. PRISMA guidelines were followed. Risk of bias was appraised using Cochrane RoB2 and Risk Of Bias In Non-Randomized Studies of Interventions (ROBIN-I) tools, and certainty of evidence using GRADE framework. RESULTS One randomized controlled trial and one observational study were included. Some aspects precluded the feasibility of a meaningful meta-analysis; hence, a qualitative review was conducted. Risk of bias was low in the trial and serious in the observational study. In the trial, the servo-controlled system did not affect normothermia (36.5-37.5°C) but was associated with increased mild hypothermia (from 22.2 to 32.9%). In the observational study, normothermia (36-38°C) increased after the introduction of the servo-controlled system and the extension to larger VLBW infants. CONCLUSION Overall, this review found very limited information on the use of thermal servo-controlled systems during stabilization of preterm and VLBW infants immediately at birth. Further research is needed to investigate the opportunity of including such approach in the neonatal thermal management in delivery room. REGISTRATION PROSPERO (CRD42022309323).

Lateral Kangaroo Care in Hemodynamic Stability of Extremely Preterm Infants: Protocol Study for a Non-Inferiority Randomized Controlled Trial CANGULAT. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 19:293. [PMID: 35010554 PMCID: PMC8750690 DOI: 10.3390/ijerph19010293] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/15/2021] [Accepted: 12/23/2021] [Indexed: 06/14/2023]
Abstract
INTRODUCTION This study aims to assess the efficacy of the modified kangaroo care lateral position on the thermal stability of preterm neonates versus conventional kangaroo care prone position. MATERIAL AND METHODS A non-inferiority randomized parallel clinical trial. Kangaroo care will be performed in a lateral position for the experimental group and in a prone position for the control group preterm. The study will take place at the neonatal intensive care unit (NICU) of a University Hospital. The participants will be extremely premature infants (under 28 weeks of gestational age) along the first five days of life, hemodynamically stable, with mother or father willing to do kangaroo care and give their written consent to participate in the study. The sample size calculated was 35 participants in each group. When the premature infant is hemodynamically stable and one of the parents stays in the NICU, the patient will be randomized into two groups: an experimental group or a control group. The primary outcome is premature infant axillary temperature. Neonatal pain level and intraventricular hemorrhage are secondary outcomes. DISCUSSION There is no scientific evidence on modified kangaroo care lateral position. Furthermore, there is little evidence of increased intraventricular hemorrhage association with the lateral head position necessary in conventional or prone kangaroo care in extremely premature newborns. Kangaroo care is a priority intervention in neonatal units increasing the time of use more and more, making postural changes necessary to optimize comfort and minimize risks with kangaroo care lateral position as an alternative to conventional prone position kangaroo care. Meanwhile, it is essential to ensure that the conventional kangaroo care prone position, which requires the head to lay sideways, is a safe position in terms of preventing intraventricular hemorrhage in the first five days of life of children under 28 weeks of gestational age.

Abstract
BACKGROUND The thermal servo-controlled systems are routinely used in neonatal intensive care units (NICUs) to accurately manage patient temperature, but their role during the immediate postnatal phase has not been previously assessed. OBJECTIVE To compare two modalities of thermal management (with and without the use of a servo-controlled system) immediately after birth. STUDY DESIGN AND SETTING Multicentre, unblinded, randomised trial conducted 15 Italian tertiary hospitals. PARTICIPANTS Infants with estimated birth weight <1500 g and/or gestational age <30+6 weeks. INTERVENTION Thermal management with or without a thermal servo-controlled system during stabilisation in the delivery room. PRIMARY OUTCOME Proportion of normothermia at NICU admission (axillary temperature 36.5°C-37.5°C). RESULTS At NICU admission, normothermia was achieved in 89/225 neonates (39.6%) with the thermal servo-controlled system and 95/225 neonates (42.2%) without the thermal servo-controlled system (risk ratio 0.94, 95% CI 0.75 to 1.17). Thermal servo-controlled system was associated with increased mild hypothermia (36°C-36.4°C) (risk ratio 1.48, 95% CI 1.09 to 2.01). CONCLUSIONS In very low birthweight infants, thermal management with the servo-controlled system conferred no advantage in maintaining normothermia at NICU admission, while it was associated with increased mild hypothermia. Thermal management of preterm infants immediately after birth remains a challenge. TRIAL REGISTRATION NUMBER NCT03844204.

Abstract
Hypothermia in pediatrics is mainly about small body size. The key thermal factor here is the large surface-to-volume ratio. Although small mammals, including human infants and children, are adapted to higher heat losses through their elevated metabolic rate and thermogenic capacity, they are still at risk of hypothermia because of a small regulatory range and an impending metabolic exhaustion. However, some small mammalian species (hibernators) use reduced metabolic rates and lowered body temperatures as adaptations to impaired energy supply. Similar to nature, hypothermia has contradictory effects in clinical pediatrics as well: In neonates, it is a serious risk factor affecting respiratory adaptation in term and developmental outcome in preterm infants. On the other hand, it is an important self-protective response to neonatal hypoxia and an evidence-based treatment option for asphyxiated babies. In children, hypothermia first enabled the surgical repair of congenital heart defects and promotes favorable outcome after ice water drowning. Yet, it is also a major threat in various prehospital and clinical settings and has no proven therapeutic benefit in pediatric critical care. All in all, pediatric hypothermia is an ambiguous issue whose harmful or beneficial effects strongly depend on the particular circumstances.

Abstract
Objectives To determine a 10-year trend of survival, morbidities and care practices, and predictors of in-hospital mortality in very preterm neonates (VPTN, gestation 22 to <32 weeks) in the Malaysian National Neonatal Registry. Design Retrospective cohort study. Setting 43 Malaysian neonatal intensive care units. Patients 29 010 VPTN (without major malformations) admitted between 1 January 2009 and 31 December 2018. Main outcome measures Care practices, survival, admission hypothermia (AH, <36.5°C), late-onset sepsis (LOS), pneumothorax, necrotising enterocolitis grade 2 or 3 (NEC), severe intraventricular haemorrhage (sIVH, grade 3 or 4) and bronchopulmonary dysplasia (BPD). Results During this 10-year period, there was increased use of antenatal steroid (ANS), lower segment caesarean section (LSCS) and early continuous positive airway pressure (eCPAP); but decreased use of surfactant therapy. Survival had increased from 72% to -83.9%. The following morbidities had decreased: LOS (from 27.9% to 7.1%), pneumothorax (from 6.0% to 2.7%), NEC (from 8.1% to 4.7%) and sIVH (from 12.2% to 7.5%). However, moderately severe AH (32.0°C-35.9°C) and BPD had increased. Multiple logistic regression analyses showed that lower birth weight, no ANS, no LSCS, admission to neonatal intensive care unit with <100 VPTN admissions/year, no surfactant therapy, no eCPAP, moderate and severe AH, LOS, pneumothorax, NEC and sIVH were significant predictors of mortality. Conclusion Survival and major morbidities had improved modestly. Failure to use ANS, LSCS, eCPAP and surfactant therapy, and failure to prevent AH and LOS increased risk of mortality.

Abstract
BACKGROUND Understanding the effect of early kangaroo mother care on survival of mild-moderately unstable neonates <2000 g is a high-priority evidence gap for small and sick newborn care. METHODS This non-blinded pragmatic randomised clinical trial was conducted at the only teaching hospital in The Gambia. Eligibility criteria included weight <2000g and age 1-24 h with exclusion if stable or severely unstable. Neonates were randomly assigned to receive either standard care, including KMC once stable at >24 h after admission (control) versus KMC initiated <24 h after admission (intervention). Randomisation was stratified by weight with twins in the same arm. The primary outcome was all-cause mortality at 28 postnatal days, assessed by intention to treat analysis. Secondary outcomes included: time to death; hypothermia and stability at 24 h; breastfeeding at discharge; infections; weight gain at 28d and admission duration. The trial was prospectively registered at www.clinicaltrials.gov (NCT03555981). FINDINGS Recruitment occurred from 23rd May 2018 to 19th March 2020. Among 1,107 neonates screened for participation 279 were randomly assigned, 139 (42% male [n = 59]) to standard care and 138 (43% male [n = 59]) to the intervention with two participants lost to follow up and no withdrawals. The proportion dying within 28d was 24% (34/139, control) vs. 21% (29/138, intervention) (risk ratio 0·84, 95% CI 0·55 - 1·29, p = 0·423). There were no between-arm differences for secondary outcomes or serious adverse events (28/139 (20%) for control and 30/139 (22%) for intervention, none related). One-third of intervention neonates reverted to standard care for clinical reasons. INTERPRETATION The trial had low power due to halving of baseline neonatal mortality, highlighting the importance of implementing existing small and sick newborn care interventions. Further mortality effect and safety data are needed from varying low and middle-income neonatal unit contexts before changing global guidelines.

"Assessing Today for a Better Tomorrow": An observational cohort study about quality of care, mortality and morbidity among newborn infants admitted to neonatal intensive care in Guinea. PLoS One 2021; 16:e0254938. [PMID: 34460846 PMCID: PMC8405010 DOI: 10.1371/journal.pone.0254938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Accepted: 07/06/2021] [Indexed: 12/05/2022] Open
Abstract
Background Neonatal mortality in Guinea accounts for about 30% of all fatalities in children younger than five years. Countrywide, specialized neonatal intensive care is provided in one single clinic with markedly limited resources. To implement targeted measures, prospective data on patient characteristics and factors of neonatal death are needed. Objective To determine the rates of morbidity and mortality, to describe clinical characteristics of admitted newborns requiring intensive care, to assess the quality of disease management, and to identify factors contributing to neonatal mortality. Methods Prospective observational cohort study of newborns admitted to the hospital between mid-February and mid-March 2019 after birth in other institutions. Data were collected on maternal/prenatal history, delivery, and in-hospital care via convenience sampling. Associations of patient characteristics with in-hospital death were assessed using cause-specific Cox proportional-hazards models. Results Half of the 168 admitted newborns underwent postnatal cardiopulmonary resuscitation. Reasons for admission included respiratory distress (49.4%), poor postnatal adaptation (45.8%), prematurity (46.2%), and infections (37.1%). 101 newborns (61.2%) arrived in serious/critical general condition; 90 children (53.9%) showed clinical signs of neurological damage. Quality of care was poor: Only 59.4% of the 64 newborns admitted with hypothermia were externally heated; likewise, 57.1% of 45 jaundiced infants did not receive phototherapy. Death occurred in 56 children (33.3%) due to birth asphyxia (42.9%), prematurity (33.9%), and sepsis (12.5%). Newborns in serious/critical general condition at admission had about a fivefold higher hazard to die than those admitted in good condition (HR 5.21 95%-CI 2.42–11.25, p = <0.0001). Hypothermia at admission was also associated with a higher hazard of death (HR 2.00, 95%-CI 1.10–3.65, p = 0.023). Conclusion Neonatal mortality was strikingly high. Birth asphyxia, prematurity, and infection accounted for 89.3% of death, aggravated by poor quality of in-hospital care. Children with serious general condition at admission had poor chances of survival. The whole concept of perinatal care in Guinea requires reconsideration.

Abstract
Neonatal resuscitation is a coordinated, team-based series of timed sequential steps that focuses on a transitional physiology to improve perinatal and neonatal outcomes. The practice of neonatal resuscitation has evolved over time and continues to be shaped by emerging evidence as well as key opinions. We present the revised Neonatal Resuscitation Guidelines for Singapore 2021. The recommendations from the International Liaison Committee on Resuscitation Neonatal Task Force Consensus on Science and Treatment Recommendations (2020) and guidelines from the American Heart Association and European Resuscitation Council were compared with existing guidelines. The recommendations of the Neonatal Subgroup of the Singapore Resuscitation and First Aid Council were derived after the work group discussed and appraised the current available evidence and their applicability to local clinical practice.

European consensus recommendations for neonatal and paediatric retrievals of positive or suspected COVID-19 patients. Pediatr Res 2021; 89:1094-1100. [PMID: 32634819 DOI: 10.1038/s41390-020-1050-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 06/15/2020] [Accepted: 06/17/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND The 2020 novel coronavirus (SARS-Cov-2) pandemic necessitates tailored recommendations addressing specific procedures for neonatal and paediatric transport of suspected or positive COVID-19 patients. The aim of this consensus statement is to define guidelines for safe clinical care for children needing inter-facility transport while making sure that the clinical teams involved are sufficiently protected from SARS-CoV-2. METHODS A taskforce, composed of members of the European Society of Paediatric and Neonatal Intensive Care (ESPNIC) Transport section and the European Society for Paediatric Research (ESPR), reviewed the published literature and used a rapid, two-step modified Delphi process to formulate recommendations regarding safety and clinical management during transport of COVID-19 patients. RESULTS The joint taskforce consisted of a panel of 12 experts who reached an agreement on a set of 17 recommendations specifying pertinent aspects on neonatal and paediatric COVID-19 patient transport. These included: case definition, personal protective equipment, airway management, equipment and strategies for invasive and non-invasive ventilation, special considerations for incubator and open stretcher transports, parents on transport and decontamination of transport vehicles. CONCLUSIONS Our consensus recommendations aim to define current best-practice and should help guide transport teams dealing with infants and children with COVID-19 to work safely and effectively. IMPACT We present European consensus recommendations on pertinent measures for transporting infants and children in times of the coronavirus (SARS-Cov-2 /COVID-19) pandemic. A panel of experts reviewed the evidence around transporting infants and children with proven or suspected COVID-19. Specific guidance on aspects of personal protective equipment, airway management and considerations for incubator and open stretcher transports is presented. Based on scant evidence, best-practice recommendations for neonatal and paediatric transport teams are presented, aiming for the protection of teams and patients. We highlight gaps in knowledge and areas of future research.

Physiologic Changes during Sponge Bathing in Premature Infants. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18052467.

Abstract
In this study, we observed physiological reactions of premature infants during sponge bathing in the neonatal intensive care unit (NICU). The infants’ body temperature, heart rate, and oxygen saturation were monitored to examine hypothermia risks during bathing. The participants of the study were 32 premature infants who were hospitalized right after their birth in the V hospital in Korea between December 2012 and August 2013. The informed consents of the study were received from the infants’ parents. The infants were randomly assigned into two-day and four-day bath cycle groups and their physiological reactions were monitored before bathing as well as 5 and 10 min after bathing. The collected data were analyzed using the SPSS statistical package through t-test. A significant drop in body temperature was noted in both groups; that is, 4-day bathing cycle and 2-day bathing cycle (p < 0.001). However, there were no significant changes in heart rate or transcutaneous oxygen levels. There was no significant change between groups at each measurement point. In order to minimize the physiological instability that may be caused during bathing, the care providers should try to complete bathing within the shortest possible time and to make bathing a pleasant and useful stimulus for infants.

Abstract
We report the case of a preterm small for gestational age male infant born at 24 weeks of gestation with a birth weight of 268 g who was discharged from our hospital without the requirement for home oxygen therapy or tube feeding. He did not experience severe intraventricular hemorrhage, periventricular leukomalacia, hearing disability, or any other serious complications. At that time (February 2019), according to the University of Iowa's Tiniest Babies Registry, he was the tiniest male infant in the world to survive without any serious complications other than severe retinopathy of prematurity that required laser therapy. Although the survival rate of infants with extremely low birth weight is improving worldwide, a high mortality rate and incidence of severe complications remain common for infants weighing <300 g at birth, particularly in male infants. In recent years, there have been frequent discussions regarding the ethical and social issues involved in treating extremely preterm infants weighing <400 g. Despite the challenges, reports of such infants surviving are increasing. Neonatal medicine has already achieved great success in treating infants weighing 400 g or more at birth. However, lack of evidence and experience may make physicians reluctant to treat infants weighing less than this. The present case demonstrates that intact survival of a marginally viable male infant with a birth weight of <300 g is possible with minimal handling and family involvement beginning shortly after birth. Our detailed description of the clinical course of this case should provide invaluable information to physicians around the world who treat such infants. This report will aid in the progress of neonatal medicine and help to address many of the social and ethical issues surrounding their care.

Abstract
BACKGROUND We assessed the efficacy of Embrace Nest Infant Warmer versus Cloth Wrap in preventing hypothermia during short-term transport from the emergency department (ED) to the neonatal intensive care unit (NICU). METHODS Neonates weighing ≥1500 g coming to the ED were randomized for transport to the NICU. Axillary temperature was measured. RESULTS A total of 120 newborns (60 per group) were enrolled. From ED exit to NICU entry, the mean (SD) temperature increased in the Embrace group by 0.37 °C (0.54), whereas it reduced by 0.38 °C (0.80) in the Cloth group (p < 0.001). Hypothermia cases reduced in the Embrace group from 39 (65%) to 21 (35%), while it increased from 21 (35%) to 39 (65%) in the Cloth group (p = 0.001) from ED exit to NICU entry. The thermoregulation for 24 h after admission to the NICU was superior in the Embrace group. CONCLUSIONS Embrace showed significantly better thermoregulation in neonates. Further studies should be done to measure its effectiveness in different environments and distances.

Abstract
OBJECTIVE Hypothermia is believed to affect more than half of Ethiopian neonates. The goal of this study is to determine risk factors for newborn hypothermia in neonates admitted to public hospitals in the east Wollega zone of western Ethiopia's neonatal intensive care unit. DESIGN Unmatched case-control study using neonates admitted to the intensive care unit. SETTING Neonatal intensive care units at public hospitals in western Ethiopia. PATIENTS Neonates admitted to intensive care units. MAIN OUTCOMES The cases were all neonates with hypothermia (less than 36.5°C) and the controls were all neonates with a body temperature of greater or equal to 36.5°C when admitted to the neonatal intensive care unit for other reasons. RESULTS The study involved the participation of 73 cases and 146 controls. The study found that delayed breastfeeding initiation after 1 hour (adjusted OR (AOR)=3.72; 95% CI: 1.39 to 10.00), admission weight less than 2500 g (AOR=3.43; 95% CI: 1.18 to 9.97), cardiopulmonary resuscitation at birth (AOR=3.42; 95% CI: 1.16 to 10.10.08), lack of immediate skin-to-skin contact with their mother (AOR=4.54; 95% CI: 1.75 to 11.81), night-time delivery (AOR=6.63; 95% CI: 2.23 to 19.77) and not wearing a cap (AOR=2.98; 95% CI: 1.09 to 8.15) were all associated with newborn hypothermia. CONCLUSIONS Neonatal hypothermia was associated with obstetric, neonatal and healthcare provider factors. As a result, special consideration should be given to the thermal care of low birthweight neonates and the implementation of warm-chain principles with low-cost thermal protection in Ethiopian public health facilities.

Abstract
BACKGROUND Incubators and radiant warmers are essential equipment in neonatal care, but the typical 1,500 to 35,000 USD cost per device makes it unaffordable for many units in low and middle-income countries. We aimed to determine whether stable preterm infants could maintain thermoregulation for 48 h in a low-cost incubator (LCI). METHODS The LCI was constructed using a servo-heater costing 200 USD and cardboard infant-chamber. We conducted this open-labeled non-inferiority randomized controlled trial in a tertiary level teaching hospital in India from May 2017 to March 2018. Preterm infants on full feeds and receiving incubator or radiant warmer care were enrolled at 32 to 36 weeks post-menstrual age. We enrolled 96 infants in two strata (Strata-1< 33 weeks, Strata-2 ≥ 33 weeks at birth). Infants were randomized to LCI or standard single-wall incubator (SSI) after negative incubator cultures and monitored for 48 h in air-mode along with kangaroo mother care. The incubator temperature was adjusted manually to maintain skin and axillary temperatures between 36.5 °C and 37.5 °C. During post-infant period after 48 h, SSI and LCI worked for 5 days and incubator temperatures were measured. The primary outcome was maintenance of skin and axillary temperatures with a non-inferiority margin of 0.2 °C. Failed thermoregulation was defined as abnormal axillary temperature (< 36.5 °C or >37.5 °C) for > 30 continuous-minutes. Secondary outcomes were incidence of hypothermia and required incubator temperature. Trial registration details: Clinical Trial Registry - India (CTRI/2015/10/006316). FINDINGS Prior to enrollment 79(82%) infants were in radiant warmer and 17(18%) infants were in incubator care. Median weight at enrollment in Strata-1 and Strata-2 for SSI vs. LCI was 1355(IQR 1250-1468) vs. 1415(IQR 1280-1582) and 1993(IQR 1595-2160) vs. 1995(IQR 1632-2237) grams. Mean skin temperature in Strata-1 and Strata-2 for SSI vs. LCI was 36.8 °C ± 0.2 vs. 36.7 °C ± 0.18 and 36.8 °C ± 0.22 vs. 36.7 °C ± 0.19. Mean axillary temperature in Strata-1 and Strata-2 for SSI vs. LCI was 36.9 °C ± 0.19 vs. 36.8 °C ± 0.16 and 36.8 °C ± 0.2 vs. 36.8 °C ± 0.19. Mixed-effect model done for repeated measures of skin and axillary temperatures showed the estimates were within the non-inferiority limit; -0.07 °C (95% CI -0.11 to -0.04) and -0.06 °C (95% CI -0.095 to -0.02), respectively. Failed thermoregulation did not occur in any infants. Mild hypothermia occurred in 11 of 48(23%) of SSI and 16 of 48(33%) of LCI, OR 1.28 (95%CI 0.85 to 1.91). Incubator temperature in LCI was higher by 0.7 °C (95%CI 0.52 to 0.91). In the post-infant period SSI and LCI had excellent reliability to maintain set-temperature with intra-class correlation coefficient of 0.93 (95%CI 0.92 to 0.94) and 0.96 (95%CI 0.96 to 0.97), respectively. INTERPRETATION Maintenance of skin and axillary temperature of stable preterm infants in LCI along with kangaroo mother care was non-inferior to SSI, but at a higher incubator temperature by 0.7 °C. No adverse events occurred and LCI had excellent reliability to maintained set-temperature. FUNDING Food and Drug Administration (Award number P50FD004895).

Abstract
To date, 18 living recommendations for the clinical care of pregnant and postpartum women with COVID-19 have been issued by the National COVID-19 Clinical Evidence Taskforce. This includes recommendations on mode of birth, delayed umbilical cord clamping, skin-to-skin contact, breastfeeding, rooming-in, antenatal corticosteroids, angiotensin-converting enzyme inhibitors, disease-modifying treatments (including dexamethasone, remdesivir and hydroxychloroquine), venous thromboembolism prophylaxis and advanced respiratory support interventions (prone positioning and extracorporeal membrane oxygenation). Through continuous evidence surveillance, these living recommendations are updated in near real-time to ensure clinicians in Australia have reliable, evidence-based guidelines for clinical decision-making.

Arch Dis Child Fetal Neonatal Ed 2020; 105:675-679. [PMID: 32350064 DOI: 10.1136/archdischild-2020-318915] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/17/2020] [Accepted: 03/30/2020] [Indexed: 02/06/2023]
Abstract
Some neural circuits within infants are not fully developed at birth, especially in preterm infants. Therefore, it is unclear whether reflexes that affect breathing may or may not be activated during the neonatal stabilisation at birth. Both sensory reflexes (eg, tactile stimulation) and non-invasive ventilation (NIV) can promote spontaneous breathing at birth, but the application of NIV can also compromise breathing by inducing facial reflexes that inhibit spontaneous breathing. Applying an interface could provoke the trigeminocardiac reflex (TCR) by stimulating the trigeminal nerve resulting in apnoea and a reduction in heart rate. Similarly, airflow within the nasopharynx can elicit the TCR and/or laryngeal chemoreflex (LCR), resulting in glottal closure and ineffective ventilation, whereas providing pressure via inflations could stimulate multiple receptors that affect breathing. Stimulating the fast adapting pulmonary receptors may activate Head's paradoxical reflex to stimulate spontaneous breathing. In contrast, stimulating the slow adapting pulmonary receptors or laryngeal receptors could induce the Hering-Breuer inflation reflex or LCR, respectively, and thereby inhibit spontaneous breathing. As clinicians are most often unaware that starting primary care might affect the breathing they intend to support, this narrative review summarises the currently available evidence on (vagally mediated) reflexes that might promote or inhibit spontaneous breathing at birth.

BMC Pregnancy Childbirth 2020; 20:646. [PMID: 33097025 PMCID: PMC7585226 DOI: 10.1186/s12884-020-03343-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 10/15/2020] [Indexed: 01/21/2023] Open
Abstract
Background Thermal control after birth is an essential part of neonatal care. However, the relationship between neonatal temperature at and after admission is unknown. This study aimed to evaluate the change between neonatal temperature at admission and at day 1, and its impact on mortality. Methods Retrospective observational study at the Beira Central Hospital, Mozambique. Axillary temperatures were recorded at admission and at day 1 in 1,226 neonates who were admitted to the Special Care Unit between January 1 and December 31, 2017. The relationship between mortality rate and temperature change was evaluated with a matrix plot and a forest plot (obtained from a logistic regression model as odds ratios with 95% confidence intervals). Results Normothermia was found in 415 neonates (33.8%) at admission and in 638 neonates (52.0%) at day 1. Mortality rate was highest in (i) neonates who remained in severe/moderate hypothermia (74%), (ii) neonates who rewarmed from hypothermia (40–55%), and (iii) neonates who chilled to severe/moderate hypothermia (38–43%). Multivariable analysis confirmed that temperature change from admission to day 1 was an independent predictor of mortality (p < 0.0001). Conclusions In a low-resource setting, one out of three neonates was found hypothermic at day 1 irrespectively of admission temperature. Relevant thermal deviations occurred in a high proportion of newborns with normothermia at admission. Being cold at admission and becoming cold or hyperthermic at day 1 were associated with increased likelihood of mortality. Appropriate actions to prevent both hypothermia and hyperthermia represent both a challenge and a priority during postnatal period.
