Dunne EA, O'Donnell CPF, Nakstad B, McCarthy LK. Thermoregulation for very preterm infants in the delivery room: a narrative review. Pediatr Res 2024; 95:1448-1454. [PMID: 38253875 PMCID: PMC11126394 DOI: 10.1038/s41390-023-02902-w] [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: 05/08/2023] [Revised: 10/28/2023] [Accepted: 11/02/2023] [Indexed: 01/24/2024]
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.

Abstract
Maternal, placental, and neonatal factors were compared between infants born at ≤29 weeks of gestational age with admission hyperthermia (>37.5○C) and euthermia (36.5-37.5○C). Admission hyperthermia was associated with longer duration of face-mask positive-pressure ventilation and infant's temperature ≥37.5○C in the delivery room. Infants born preterm with admission hyperthermia had greater odds of developing necrotizing enterocolitis and neurodevelopmental impairment.

Abstract
AIM We aimed to explore whether hypothermia during the transfer of extremely low birth weight (ELBW) infants was associated with increased morbidity and mortality. METHODS Retrospective cohort study of transfers of ELBW infants by the London Neonatal Transfer Service between April 2015 and January 2017. Hypothermia was defined as an axillary temperature below 36.5°C. RESULTS Hypothermia was recorded in 36-47% of the 146 transfers depending on the time point of measurement from admission at the referring unit to admission at the receiving unit. Infants with hypothermia had a lower gestational age [25.1 (24.1-26.6) versus 26.0 (25.3-27.0) weeks, p < 0.001], birth weight [750 (600-830) versus 800 (730-885) gr, p = 0.004) and age at referral [1 (0.8-3) versus 1.5 (1-4) hours, p = 0.049] compared to infants without hypothermia. Infants with hypothermia had a longer median (IQR) duration of invasive ventilation [22(6-44) days] compared to infants without hypothermia [10 (4-21) days, p = 0.002]. Infants with hypothermia had a higher incidence of a patent ductus arteriosus and mortality before discharge from neonatal care compared to infants without hypothermia (79% vs. 27%, p = 0.043 and 29% vs. 13%, p = 0.025, respectively). CONCLUSION Among ELBW infants, hypothermia during transfer was common, particularly in infants of lower gestational age. Hypothermia was associated with a longer duration of ventilation and increased mortality before discharge from neonatal care.

Abstract
AIM To evaluate delivery room (DR) interventions to prevent hypothermia and improve outcomes in preterm newborn infants <34 weeks' gestation. METHODS Medline, Embase, CINAHL and CENTRAL were searched till 22nd July 2022. Randomized controlled trials (RCTs), non-RCTs and quality improvement studies were considered. A random effects meta-analysis was performed, and the certainty of evidence was evaluated using GRADE guidelines. RESULTS DR temperature of ≥23 °C compared to standard care improved temperature outcomes without an increased risk of hyperthermia (low certainty), whereas radiant warmer in servo mode compared to manual mode decreased mean body temperature (MBT) (moderate certainty). Use of a plastic bag or wrap (PBW) improved normothermia (low certainty), but with an increased risk of hyperthermia (moderate certainty). Plastic cap improved normothermia (moderate certainty) and when combined with PBW improved MBT (low certainty). Use of a cloth cap decreased moderate hypothermia (low certainty). Though thermal mattress (TM) improved MBT, it increased risk of hyperthermia (low certainty). Heated-humidified gases (HHG) for resuscitation decreased the risk of moderate hypothermia and severe intraventricular hemorrhage (very low to low certainty). None of the interventions was shown to improve survival, but sample sizes were insufficient. CONCLUSIONS DR temperature of ≥23 °C, radiant warmer in manual mode, use of a PBW and a head covering is suggested for preterm newborn infants <34 weeks' gestation. HHG and TM could be considered in addition to PBW provided resources allow, in settings where hypothermia incidence is high. Careful monitoring to avoid hyperthermia is needed.

[PMID: 36054141 PMCID: PMC9439247 DOI: 10.1371/journal.pone.0273946] [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: 12/22/2021] [Accepted: 08/18/2022] [Indexed: 11/18/2022] Open
Abstract
Introduction
In very low birth weight (VLBW) infants, hypothermia immediately following birth is common even in countries rich in medical resources. The purpose of this study is to design a standard prevention bundle that decreases the rate of hypothermia among infants after birth and to investigate efficacy of the bundle and short-term outcomes for VLBW infants.
Methods
This quality improvement project was conducted from February 2017 to July 2018 on all VLBW preterm infants admitted at a single referral level III neonatal intensive care unit. The infants were classified into the pre-intervention (February to September 2017) and post-intervention (October 2017 to July 2018) groups according to the time periods when they were recruited. During the pre-intervention period, we analyzed the primary causes of hypothermia, developed solutions corresponding to each cause, integrated all solutions into a prevention bundle, and applied the bundle during the post-intervention period. Afterwards, the incidence of neonatal hypothermia and short-term outcomes, such as intraventricular hemorrhage (IVH), acidosis, and shock requiring inotropic agents, in each group were compared.
Results
A total of 95 VLBW infants were enrolled in the study, including 37 pre-intervention, and 58 post-intervention cases. The incidence of hypothermia in preterm infants decreased significantly upon the implementation of our prevention bundle, both in the delivery room (from 45.9% to 8.6%) and on admission (59.5% to 15.5%). In addition, the short-term outcomes of VLBW infants improved significantly, especially with the decreased incidence of IVH (from 21.6% to 5.2%, P = 0.015).
Conclusions
Our standardized prevention bundle for preventing hypothermia in VLBW infants is effective and decreased the IVH rate in VLBW infants. We strongly believe that this prevention bundle is a simple, low-cost, replicable, and effective tool that hospitals can adopt to improve VLBW infant outcomes.

Improvement in thermoregulation outcomes following the implementation of a thermoregulation bundle for preterm infants. J Paediatr Child Health 2022; 58:1201-1208. [PMID: 35353411 PMCID: PMC9310766 DOI: 10.1111/jpc.15949] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 02/22/2022] [Accepted: 02/27/2022] [Indexed: 11/29/2022]
Abstract
AIM Hypothermia is associated with increased morbidity and mortality in preterm infants. A local audit revealed 60% preterm infants ≤32 weeks gestation and/or very low birth weight (VLBW) infants (<1500 g) had an abnormal body temperature at admission. This study compares thermoregulatory outcomes before and after the implementation of a thermoregulation bundle in the birthing environment. METHODS This retrospective cohort study reviewed thermoregulatory data for all inborn preterm (≤32 weeks) and/or VLBW infants for a period of 30 months before (Group 1: 1st January 2013 to 30 June 2015) and after changes to thermoregulation practice (Group 2: 1st July 2015 to 31 December 2017). The key practice changes included: improved anticipation and staff preparedness, wrapping infant in a polyethylene sheet, using a polyethylene lined bonnet, using servo-control mode at birth and during transport. RESULTS There were 282 and 286 infants in group 1 and group 2 respectively, with similar baseline characteristics. A clinically and statistically significant improvement was observed in the proportion of infants with normothermia (33% in group 1 to 60% in group 2, P < 0.0001) including the sub-group of extremely preterm (<28 weeks gestation) infants (38 to 60%, P = 0.0083). A higher mean admission temperature was observed for group 2 (36.10°C ± 0.78 in group 1 vs 36.52°C ± 0.61 in group 2, P < 0.0001). Moderate hypothermia was reduced by two-thirds in group 2 (41-12%, P = <0.0001). CONCLUSIONS The introduction of a thermoregulation bundle improved admission temperature, improved the proportion of normothermia and reduced moderate hypothermia in preterm infants.

Delivery Room Interventions for Hypothermia in Preterm Neonates: A Systematic Review and Network Meta-analysis. JAMA Pediatr 2021; 175:e210775. [PMID: 34028513 PMCID: PMC8145154 DOI: 10.1001/jamapediatrics.2021.0775] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Accepted: 02/26/2021] [Indexed: 12/31/2022]
Abstract
Importance Prevention of hypothermia in the delivery room is a cost-effective, high-impact intervention to reduce neonatal mortality, especially in preterm neonates. Several interventions for preventing hypothermia in the delivery room exist, of which the most beneficial is currently unknown. Objective To identify the delivery room thermal care intervention that can best reduce neonatal hypothermia and improve clinical outcomes for preterm neonates born at 36 weeks' gestation or less. Data Sources MEDLINE, the Cochrane Central Register of Controlled Trials, Embase, and CINAHL databases were searched from inception to November 5, 2020. Study Selection Randomized and quasi-randomized clinical trials of thermal care interventions in the delivery room for preterm neonates were included. Peer-reviewed abstracts and studies published in non-English language were also included. Data Extraction and Synthesis Data from the included trials were extracted in duplicate using a structured proforma. A network meta-analysis with bayesian random-effects model was used for data synthesis. Main Outcomes and Measures Primary outcomes were core body temperature and incidence of moderate to severe hypothermia on admission or within the first 2 hours of life. Secondary outcomes were incidence of hyperthermia, major brain injury, and mortality before discharge. The 9 thermal interventions evaluated were (1) plastic bag or plastic wrap covering the torso and limbs with the head uncovered or covered with a cloth cap; (2) plastic cap covering the head; (3) skin-to-skin contact; (4) thermal mattress; (5) plastic bag or plastic wrap with a plastic cap; (6) plastic bag or plastic wrap along with use of a thermal mattress; (7) plastic bag or plastic wrap along with heated humidified gas for resuscitation or for initiating respiratory support in the delivery room; (8) plastic bag or plastic wrap along with an incubator for transporting from the delivery room; and (9) routine care, including drying and covering the body with warm blankets, with or without a cloth cap. Results Of the 6154 titles and abstracts screened, 34 studies that enrolled 3688 neonates were analyzed. Compared with routine care alone, plastic bag or wrap with a thermal mattress (mean difference [MD], 0.98 °C; 95% credible interval [CrI], 0.60-1.36 °C), plastic cap (MD, 0.83 °C; 95% CrI, 0.28-1.38 °C), plastic bag or wrap with heated humidified respiratory gas (MD, 0.76 °C; 95% CrI, 0.38-1.15 °C), plastic bag or wrap with a plastic cap (MD, 0.62 °C; 95% CrI, 0.37-0.88 °C), thermal mattress (MD, 0.62 °C; 95% CrI, 0.33-0.93 °C), and plastic bag or wrap (MD, 0.56 °C; 95% CrI, 0.44-0.69 °C) were associated with greater core body temperature. Certainty of evidence was moderate for 5 interventions and low for plastic bag or wrap with a thermal mattress. When compared with routine care alone, a plastic bag or wrap with heated humidified respiratory gas was associated with less risk of major brain injury (risk ratio, 0.23; 95% CrI, 0.03-0.67; moderate certainty of evidence) and a plastic bag or wrap with a plastic cap was associated with decreased risk of mortality (risk ratio, 0.19; 95% CrI, 0.02-0.66; low certainty of evidence). Conclusions and Relevance Results of this study indicate that most thermal care interventions in the delivery room for preterm neonates were associated with improved core body temperature (with moderate certainty of evidence). Specifically, use of a plastic bag or wrap with a plastic cap or with heated humidified gas was associated with lower risk of major brain injury and mortality (with low to moderate certainty of evidence).

Abstract
OBJECTIVE To assess feasibility, safety, usability and learnability of delivery room care and resuscitation with intact placental circulation (RIPC) at mother's bedside. MATERIALS AND METHODS We included neonates ≥24 weeks GA after parental consent. Both in vigorous and babies requiring resuscitation, appropriate steps of resuscitation were provided with intact cord till 3 min using RIPC warmer. Outcomes were assessed by set criteria and standard system usability scale. RESULTS Of 380 enrolled, intervention was feasible in 376 babies (98.9%). Safety criteria were met in all 376 babies received onto the trolley (100%). Median GA was 38 (37-39) weeks and median BW 2740 (2330-3120) g. Of 376, 92 required resuscitation; 90 (97.8%) PPV, 49 (53.2%) intubations and 13 (14.1%) chest compressions. System Usability Score rated >68 (good) in 90% and 52-68 (fair) in 10%. Temperature at 5 min was 36.5 ± 0.1. CONCLUSIONS Delivery room care and neonatal RIPC is feasible and safe across gestations.

Abstract
BACKGROUND Newborns, particularly premature newborns, are susceptible to hypothermia when transitioning from birth to admission to the NICU, potentially leading to increased mortality and morbidity. Despite attention to this issue, our rate of admission hypothermia was 39.8%. METHODS We aimed to reduce the rate of admission hypothermia for all inborn infants admitted to our institution to <10%. We undertook a quality improvement effort that spanned from 2013 through 2019 in our level IV NICU. Current state analysis involved investigating patient risk factors for hypothermia and staff understanding of hypothermia prevention. Improvement cycles included auditing processes, an in-hospital relocation of our NICU, expanded use of chemical heat mattresses and polyethylene bags, and staff education. Improvement was evaluated by using Shewhart control charts. RESULTS We demonstrated a reduction in admission hypothermia from 39.8% to 9.9%, which was temporally related to educational efforts and expanded use of chemical heat mattresses and polyethylene bags. There was not an increase in admission hyperthermia over this time period. We found that our group at highest risk of admission hypothermia was not our most premature cohort but those infants born between 33 and 36 6/7 weeks' gestation and those infants prenatally diagnosed with congenital anomalies. CONCLUSIONS Expanded use of polyethylene bags and chemical heat mattresses can improve thermoregulation particularly when combined with staff education. Although premature infants have been the focus of many hypothermia prevention efforts, our data suggest that older infants, and those infants born with congenital anomalies, require additional attention.

The effect of thermoregulation quality improvement initiatives on the admission temperature of premature/very low birth-weight infants in neonatal intensive care units: A systematic review.

[PMID: 31909894 DOI: 10.1111/jspn.12286] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 12/12/2019] [Accepted: 12/16/2019] [Indexed: 12/22/2022]
Abstract
PURPOSE The purpose of this review was to ascertain the impact of thermoregulation quality improvement initiatives (QIs) on the admission temperatures of premature/very-low-birth-weight infants in neonatal intensive care units (NICUs). METHODS A systematic search of databases Cumulative Index to Nursing and Allied Health Literature, Medline, Embase, and the Cochrane library was carried out. Specific inclusion and exclusion criteria were adhered to, with no publication date limitations added. The chosen studies were examined for quality, data were extracted and analysed, before a narrative synthesis was performed. The last search occurred on January 7, 2019, with PRISMA flow diagrams completed for identified studies. RESULTS Ten studies of varying methodology design were included in this review. Variations of thermoregulation interventions were included in the 10 studies. Nevertheless, all of them demonstrated that admission temperature rates can be significantly improved by implementing a thermoregulation QI. The multidisciplinary team and ongoing education were seen as much needed components to the overall sustainability, and continuing success of the QI's. PRACTICAL IMPLICATIONS This systematic review determines that thermoregulation QIs can positively impact the admission temperatures of premature/very-low-birth-weight infants in the NICU. Prevention of hypothermia is aimed at reducing the risks of developing major neonatal morbidities. The pooling of the results from the 10 studies helps in the sharing of outcome measures and thus, improving quantitative synthesis. More frequent monitoring of the axillary temperature would help in preventing hypothermia and hyperthermia occurring. Ongoing education and staff training are essential for managing thermoregulation successfully. Examining the compliance rates to such quality initiatives, and the variations in interventions would benefit from further research to ensure better standardisation of clinical practice.

Abstract
Immediately after birth through spontaneous breaths, infants' clear lung liquid replacing it with air, and gradually establishing a functional residual capacity to achieve gas exchange. Most infants start breathing independently after birth and ~3% of infants who require positive pressure ventilation. When newborns fail to start breathing the current neonatal resuscitation guidelines recommend initiatingpositive pressure ventilationusing a face mask and a ventilation device. Adequate ventilation is the cornerstone of successful neonatal resuscitation; therefore, it is mandatory that anybody involved in neonatal resuscitation is trained in mask ventilation techniques. One of the main problems with mask ventilation is that it is very subjective with direct feedback lacking and not uncommonly, the resuscitator does not realise that their technique is unsatisfactory. Many studies have shown that monitoring tidal volume and leak around the mask or endotracheal tube enables the resuscitator to identify the problem and adjust their technique to reduce the leak and deliver and appropriate tidal volume. This chapter discusses the currently available monitoring devices used during stabilization/resuscitation in the delivery room.

Abstract
INTRODUCTION There is a myriad of factors that can lead to temperature derangements in anesthetized children undergoing magnetic resonance imaging (MRI). Temperature abnormalities in pediatric patients are associated with increased morbidity and mortality. Although some reports have looked at this topic, to our knowledge, no studies have continuously monitored temperature throughout the MRI scan. The purpose of this study is to determine the impact of MRI on body temperature for anesthetized children undergoing MRI using continuous temperature measurement, identify patient risk factors to develop temperature abnormalities, and determine the effect of temperature derangements on perianesthetic complications. METHODS This retrospective, single-center study evaluated 285 pediatric outpatients from January 1, 2018, to March 31, 2018, who were less than 8 years old and underwent anesthesia for an MRI scan. Temperature, postanesthesia care unit length of stay, and demographic data were collected retrospectively using chart review and data extraction from electronic medical records. Statistical analyses included unpaired t test, chi-square test, and simple and multiple linear regressions. RESULTS Sixty-three percent (179/285) of children in our study had a median temperature less than 36°C during their MRI scan. There were no patients who had a median temperature greater than 38°C during their MRI scan. There were no identifiable patient risk factors for the development of hypothermia. Those who developed hypothermia did not have an increased rate of perianesthetic complications. CONCLUSION MRI in anesthetized children is associated with hypothermia but does not correlate with any significant perianesthetic complications.

Abstract
Introduction: Review of very low birth weight (VLBW) and extremely low birth weight (ELBW) neonates transported by our specialized pediatric/neonatal transport team revealed hypothermia in up to 52% of admissions. This project aimed to decrease the incidence of hypothermia in VLBW and ELBW neonates requiring transport between facilities from 52% to <20% over 1 year. Methods: In response to gaps in knowledge and barriers to care revealed by a survey administered to transport personnel, we used a standard quality improvement plan-do-study-act model to introduce new equipment and a comprehensive thermoregulation protocol via standardized education. The primary outcome measure was the incidence of hypothermia (axillary temperature < 36.5°C) in transported VLBW and ELBW neonates. The process measure was compliance with the protocol. The balancing measures were unintended hyperthermia and transport team ground time. Transport personnel were updated on progress via meetings and run charts. Results: We reduced the incidence of hypothermia to 17% in 1 year. Compliance with the protocol improved from 60% to 76%. There was no increase in unintended hyperthermia (5% preintervention, 4% intervention, 7% surveillance, P = 0.76) or transport team ground time (in hours) (1.2 ± 0.9 preintervention versus 1.3 ± 0.8 intervention versus 1.2 ± 0.7 surveillance, P = 0.2). Conclusions: Quality improvement methods were used to develop an evidence-based, standardized approach to thermal support in VLBW and ELBW neonates undergoing transport between facilities. Following the implementation of this approach, we achieved the desired percent decrease in the incidence of hypothermia.

Abstract
A high incidence of postnatal hypothermia has been reported in high-as well low-resource countries and it remains an independent predictor of neonatal morbidity and mortality, especially in very preterm infants in all settings. The temperature of newly born infants should be maintained between 36.5 and 37.5 °C after birth through admission and stabilization. Interventions to achieve this may include environmental temperature 23-25 °C, use of radiant warmers, exothermic mattresses, woollen or plastic caps, plastic wraps, humidified and heated gases. Skin-to-skin contact has been used, especially in low-resource settings. The combinations of these interventions applied to quality improvement initiatives, including staff training, use of checklists, and continuous feedback with the staff involved in the management of the neonate, are key factors to prevent heat loss from delivery room to admission to the neonatal intensive care unit. The admission temperature should be recorded as a predictor of outcomes as well as a quality indicator.

Abstract
OBJECTIVE To assess the efficacy of adding plastic bag or portable thermal nest (PTN) to standard care in preventing hypothermia soon after birth in 1500-2499 g infants. METHODS Infants were randomized into standard thermal care alone, plastic bag with standard care or PTN with standard care. Axillary temperature was measured at admission and every 30 min till euthermia. All babies were followed-up till day 7. RESULTS We recruited 300 infants: plastic bag (101), PTN (99) and standard care group (100). Admission temperature was 36.4 °C (0.52) in plastic bag group, 36.3 °C (0.50) in PTN and 36.1 °C (0.59) in standard care group (p < 0.001). Incidence of hypothermia was lowest in plastic bag group (44.6%), followed by PTN (60%) and standard care (67%). Secondary outcomes were comparable. CONCLUSION Addition of plastic bag or PTN to standard care significantly reduces incidence and duration of hypothermia soon after birth. Plastic bag is more effective than PTN.

Abstract
AIM The efficacy and safety of three polyethylene bags commonly used to prevent hypothermia in premature infants was assessed. METHODS To simulate transfer from the delivery room to a secondary care unit, a thermally stable, bonneted mannequin (skin temperature: 34.4 °C) was placed in a climate chamber under different conditions: with a radiant warmer, with various polyethylene bags (open on one side, closed by a draw-string at the neck, or a "life support pouch" with several access points) or without a bag. RESULTS With the radiant warmer turned on, the mean reduction in heat loss from the nude mannequin was 50.8 ± 1.7% (p < 0.0001, vs. warmer off). The mean reduction in heat loss (vs. no bag) was 55.0 ± 0.9% for the drawstring bag, 49.0 ± 2.2% for the standard bag (p = 0.0001), and 48.1 ± 0.7% for the life support pouch (p = 0.006). When a radiant warmer + polyethylene bag were used, heat stress (body temperature: 38 °C) and severe hyperthermia (40 °C) occurred after 11 and 34 min, respectively. CONCLUSION Caution must be taken when using a radiant warmer and polyethylene bag with a premature infant. Heat stress can occur in only 11 min. Continuous body temperature monitoring is therefore required.

[PMID: 28886399 DOI: 10.1016/j.jped.2017.06.016] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2017] [Revised: 05/30/2017] [Accepted: 06/01/2017] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE To evaluate the effectiveness of a thermoregulation bundle for preventing admission hypothermia in very low-birth weight preterm infants. METHODS Interventional study with retrospective evaluation of data undertaken in a tertiary neonatal unit including all very low-birth weight preterm infants (<1500g) born at and admitted to the unit. Two periods were compared: before intervention (PI; 01/01/2012 to 02/28/2014_ and after intervention (PII; 04/01/2014 to 11/30/2016). The intervention started in March 2014. At PI procedures in the delivery room were: placement in a crib with a radiant heat source, doors always closed, polyethylene body plastic bag, double cap (plastic and cotton mesh), room temperature between 24 to 27°C and transport to neonatal unit in a pre-heated incubator (36-37.0°C). At PII, there was a reinforcement on not opening the plastic bag during the entire resuscitation process, even at an advanced stage, and the anthropometric measures and routine care were performed in the neonatal unit. Maternal, delivery, and neonatal variables were compared. Admission hypothermia was considered when admission axillary temperature was <36.0°C. Periodic results were shown to the team every six months and results were discussed. RESULTS The incidence of admission hypothermia was reduced significantly in PII (37.2 vs. 14.2%, p<0.0001) and admission temperature medians were higher (36.1 vs. 36.5°C, p<0.001). At PII, there was an increase in the number of infants transported with oxygen (49.5 vs. 75.5%, p<0.0001). No differences were observed regarding birth weight and gestational age. CONCLUSION There was a very important reduction in admission hypothermia incidence and a higher median admission temperature after continued protocol implementation.

Abstract
OBJECTIVE To decrease rates of admission hypothermia (<36 °C) in very-low-birth-weight (VLBW) newborns (<1,500 g). DESIGN Quality improvement initiative. SETTING/LOCAL PROBLEM Urban, Level IV NICU with 32 patient beds. The number of VLBW newborns admitted with temperatures less than 36 °C was greater than in comparable NICUs in the Vermont Oxford Network. PARTICIPANTS Neonates born in 2016 who weighed less than 1,500 g at birth. INTERVENTION/MEASUREMENTS Based on the literature and the needs of our unit, our team decided to focus efforts on equipment (chemical mattresses and polyurethane-lined hats for newborns who weighed <1,000 g and polyurethane-lined hats for newborns who weighed <1,500 g), staff education/awareness, and temperature documentation and workflow. Axillary temperature measurements for all neonates who weighed less than 1,500 g were tracked on admission. RESULTS The processes involved in this quality improvement initiative were successfully implemented, and use of new equipment began January 1, 2016. In 2016, only 9.6% (n = 7) of VLBW newborns were admitted with temperatures less than 36 °C, compared with 20.2% (n = 19) in 2015 and 32.4% (n = 24) in 2014 (p = .003). Overall, the mean admission temperature for neonates who weighed less than 1,500 g rose from 36.2 °C in 2014 to 36.6 °C in 2016 (p = .001). CONCLUSION We reduced the number of VLBW neonates admitted with temperatures less than 36 °C and increased overall admission temperatures for neonates who weighed less than 1,500 g with the addition of polyurethane-lined hats and chemical mattresses.

Abstract
BACKGROUND Newborn admission temperature is a strong predictor of outcomes across all gestations. Hypothermia immediately after birth remains a worldwide issue and, if prolonged, is associated with harm. Keeping preterm infants warm is difficult even when recommended routine thermal care guidelines are followed in the delivery room. OBJECTIVES To assess the efficacy and safety of interventions designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room, compared with routine thermal care or any other single/combination of intervention(s) also designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 5), MEDLINE via PubMed (1966 to 30 June 2016), Embase (1980 to 30 June 2016), and CINAHL (1982 to 30 June 2016). We also searched clinical trials databases, conference proceedings, and reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Trials using randomised or quasi-randomised allocations to test interventions designed to prevent hypothermia (apart from 'routine' thermal care) applied within 10 minutes after birth in the delivery room for infants at < 37 weeks' gestation and/or birth weight ≤ 2500 grams. DATA COLLECTION AND ANALYSIS We used Cochrane Neonatal methods when performing data collection and analysis. MAIN RESULTS Twenty-five studies across 15 comparison groups met the inclusion criteria, categorised as: barriers to heat loss (18 studies); external heat sources (three studies); and combinations of interventions (four studies).Barriers to heat loss Plastic wrap or bag versus routine carePlastic wraps improved core body temperature on admission to the neonatal intensive care unit (NICU) or up to two hours after birth (mean difference (MD) 0.58°C, 95% confidence interval (CI) 0.50 to 0.66; 13 studies; 1633 infants), and fewer infants had hypothermia on admission to the NICU or up to two hours after birth (typical risk ratio (RR) 0.67, 95% CI 0.62 to 0.72; typical risk reduction (RD) -0.25, 95% CI -0.29 to -0.20; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 4 to 5; 10 studies; 1417 infants). Risk of hyperthermia on admission to the NICU or up to two hours after birth was increased in infants in the wrapped group (typical RR 3.91, 95% CI 2.05 to 7.44; typical RD 0.04, 95% CI 0.02 to 0.06; number needed to treat for an additional harmful outcome (NNTH) 25, 95% CI 17 to 50; 12 studies; 1523 infants), but overall, fewer infants receiving plastic wrap were outside the normothermic range (typical RR 0.75, 95% CI 0.69 to 0.81; typical RD -0.20, 95% CI -0.26 to -0.15; NNTH 5, 95% CI 4 to 7; five studies; 1048 infants).Evidence was insufficient to suggest that plastic wraps or bags significantly reduce risk of death during hospital stay or other major morbidities, with the exception of reducing risk of pulmonary haemorrhage.Evidence of practices regarding permutations on this general approach is still emerging and has been based on the findings of only one or two small studies.External heat sourcesEvidence is emerging on the efficacy of external heat sources, including skin-to-skin care (SSC) versus routine care (one study; 31 infants) and thermal mattress versus routine care (two studies; 126 infants).SSC was shown to be effective in reducing risk of hypothermia when compared with conventional incubator care for infants with birth weight ≥ 1200 and ≤ 2199 grams (RR 0.09, 95% CI 0.01 to 0.64; RD -0.56, 95% CI -0.84 to -0.27; NNTB 2, 95% CI 1 to 4). Thermal (transwarmer) mattress significantly kept infants ≤ 1500 grams warmer (MD 0.65°C, 95% CI 0.36 to 0.94) and reduced the incidence of hypothermia on admission to the NICU, with no significant difference in hyperthermia risk.Combinations of interventionsTwo studies (77 infants) compared thermal mattresses versus plastic wraps or bags for infants at ≤ 28 weeks' gestation. Investigators reported no significant differences in core body temperature nor in the incidence of hypothermia, hyperthermia, or core body temperature outside the normothermic range on admission to the NICU.Two additional studies (119 infants) compared plastic bags and thermal mattresses versus plastic bags alone for infants at < 31 weeks' gestation. Meta-analysis of these two studies showed improvement in core body temperature on admission to the NICU or up to two hours after birth, but an increase in hyperthermia. Data show no significant difference in the risk of having a core body temperature outside the normothermic range on admission to the NICU nor in the risk of other reported morbidities. AUTHORS' CONCLUSIONS Evidence of moderate quality shows that use of plastic wraps or bags compared with routine care led to higher temperatures on admission to NICUs with less hypothermia, particularly for extremely preterm infants. Thermal mattresses and SSC also reduced hypothermia risk when compared with routine care, but findings are based on two or fewer small studies. Caution must be taken to avoid iatrogenic hyperthermia, particularly when multiple interventions are used simultaneously. Limited evidence suggests benefit and no evidence of harm for most short-term morbidity outcomes known to be associated with hypothermia, including major brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotising enterocolitis, and nosocomial infection. Many observational studies have shown increased mortality among preterm hypothermic infants compared with those who maintain normothermia, yet evidence is insufficient to suggest that these interventions reduce risk of in-hospital mortality across all comparison groups. Hypothermia may be a marker for illness and poorer outcomes by association rather than by causality. Limitations of this review include small numbers of identified studies; small sample sizes; and variations in methods and definitions used for hypothermia, hyperthermia, normothermia, routine care, and morbidity, along with lack of power to detect effects on morbidity and mortality across most comparison groups. Future studies should: be adequately powered to detect rarer outcomes; apply standardised morbidity definitions; focus on longer-term outcomes, particularly neurodevelopmental outcomes.

Abstract
OBJECTIVE To determine whether the use of heated-humidified gases for respiratory support during the stabilization of infants <30 weeks of gestational age (GA) in the delivery room reduces rates of hypothermia on admission to the neonatal intensive care unit (NICU). STUDY DESIGN A multicenter, unblinded, randomized trial was conducted in Melbourne, Australia, between February 2013 and June 2015. Infants <30 weeks of GA were randomly assigned to receive either heated-humidified gases or unconditioned gases during stabilization in the delivery room and during transport to NICU. Infants born to mothers with pyrexia >38°C were excluded. Primary outcome was rate of hypothermia on NICU admission (rectal temperature <36.5°C). RESULTS A total of 273 infants were enrolled. Fewer infants in the heated-humidified group were hypothermic on admission to NICU (36/132 [27%]) compared with controls (61/141 [43%], P < .01). There was no difference in rates of hyperthermia (>37.5°C); 20% (27/132) in the heated-humidified group compared with 16% (22/141) in the controls (P = .30). There were no differences in mortality or respiratory outcomes. CONCLUSIONS The use of heated-humidified gases in the delivery room significantly reduces hypothermia on admission to NICU in preterm infants, without increased risk of hyperthermia.

Abstract
Premature infants tend to lose heat quickly. This loss can be aggravated when they have received an invasive procedure involving a venous puncture. This research uses crossover design by conducting 2 intervention tests to compare 2 different treatments on the same sample. This research involved 2 groups with 18 premature infants in each. The process of data analysis used a statistical independent t test. Interventions conducted in an open incubator showed a p value of .001 which statistically related to heat loss in premature infants. In contrast, the radiant warmer p value of .001 statistically referred to a different range of heat gain before and after the venous puncture was given. The radiant warmer saved the premature infant from hypothermia during the invasive procedure. However, it is inadvisable for routine care of newborn infants since it can increase insensible water loss.

Abstract
BACKGROUND Hypothermia is a common problem in preterm infants immediately following delivery.Local problem:The rate of admission hypothermia in our neonatal intensive care unit (NICU) was above the rate of comparable NICUs in the Vermont Oxford Network. METHODS To reduce the rate of preterm admission hypothermia, a quality improvement (QI) project was implemented, utilizing the plan-do-study-act (PDSA) methodology. A guideline for delivery room thermoregulation management in <35-week infants at the University of Virginia was created and put into practice by a multidisciplinary team. INTERVENTIONS Clinical practice changes in the guideline included: increasing operating room temperatures, obtaining a 10-min axillary temperature, using an exothermic mattress for all infants <35 weeks, and using a polyethylene wrap for infants <32 weeks. RESULTS The baseline rate of hypothermia (<36.5 °CC) was 63%. Three PDSA cycles data were completed on 168 consecutive preterm births. The post-implementation rate of hypothermia (<36.5 °C) was reduced to 30% (P<0.001). The incidence of moderate hypothermia (< 36 °C) was reduced from a baseline of 29% to a rate of 9% (P<0.001). CONCLUSION Use of a multidisciplinary guideline to increase preterm NICU admission temperatures resulted in a decrease in hypothermic infants.

Abstract
Introduction: Preterm infants are unable to regulate their
body temperature and there are insufficient research evidences on different kinds of
covers for hospitalized preterm infants; therefore, the present study was conducted with
the aim of comparing the effects of plastic and blanket covers on the body temperature of
preterm infants under radiant warmer. Methods: This randomized cross-over clinical trial was
carried out upon 80 infants with the gestational age of 28-30 weeks and birth weight of
800- 1250 gr who were in Neonatal Intensive Care Unit on the second day of their
hospitalization. The study lasted for two days. In group 1, the plastic cover was used
during the first day of the study while the blankets were used during the second day.
Infants’ heads were kept out of the cover and coated with a hat. In group 2, the plastic
cover was used during the first day of the study while the blanket was used during second
day. Digital thermometer was used to measure infants’ axillary temperature. The data was
analyzed using SPSS ver 13 and MiniTab software. Descriptive statistics, (Mean (SE),
95%CI) and inferential statistics (Repeated measurement and ANCOVA tests) were used. Results: The mean body temperature of the infants in the
group covered with the plastic was calculated to be higher and the warmer was set on low
temperature. Conclusion: Using plastic cover during the first few days of
hospitalization in NICU resulted in regulation of preterm infants’ body temperature.

Abstract
BACKGROUND Very low birth-weight (<1500 g) infants are vulnerable to their environment during the first hour after birth. We designed an evidence-based golden hour protocol (GHP) with a goal to stabilize and perform admission procedures within 1 hour of birth at a level IIIB neonatal intensive care unit (NICU). PURPOSE The aim of this quality improvement project was to ascertain whether an evidence-based GHP would improve care efficiency and short-term outcomes. METHODS Rapid cycles of change using Plan Do Study Act were utilized to document progress and gain knowledge during the quality improvement project. Measures were plotted with statistical process control methods (SPC), which analyzed improvement over time. RESULTS Both admission temperature and glucose-level means were within reference range throughout the project and predicted a stable process. We observed significantly decreased time to initiation of intravenous fluids and antibiotics. An upward trend of surfactant administration within the first 2 hours of life was also observed. IMPLICATIONS FOR PRACTICE The use of a GHP provided an organized approach to admission procedures and care. By using a checklist and recording intervention times, NICU caregivers were more aware of time management for each intervention and were able to decrease time to initiation of intravenous fluids and antibiotics. IMPLICATIONS FOR RESEARCH Future research should focus on establishing normal blood pressure ranges and safe pain management during the "golden hour" and beyond. Future quality improvement should focus on improving subsequent temperature and blood glucose levels after admission umbilical artery and venous catheter placement.

Abstract
RATIONALE AND OBJECTIVES Neonates are at increased risk for cold stress and hypothermia in cool environments. An infant transport mattress (ITM) is commonly used to increase neonate temperature during transport and has been used during CT scanning. This study determined the impact of an ITM on radiation dose and image artifacts during CT scanning. MATERIALS AND METHODS CT images from a single clinical patient scanned with an ITM were reviewed, and observations of image artifacts were recorded. A phantom was scanned with and without the ITM while varying tube-current modulation, reconstruction method, slice thickness, metal reduction algorithm, tube voltage, and tube current. The effects of the ITM on computed tomography dose index (CTDIvol), mean Hounsfield unit (HU), and HU standard deviation were recorded. RESULTS The clinical patient scan demonstrated significantly decreased mean HU and increased HU standard deviation. In the phantom, the ITM increased CTDIvol 27% and induced an artifact that decreased the mean HU by 3.5 HU and increased HU standard deviation by 4.6 HU. Angular tube-current modulation, strong iterative reconstruction, thick slices, metal artifact reduction, and high mA reduced the artifact. CONCLUSIONS Using ITM during CT scanning is not recommended given the relatively brief scanning time, increased dose, and induced image artifacts. Based on our results, several acquisition parameters may be altered to mitigate the image artifact if an ITM is required during scanning.

Abstract
OBJECTIVE To determine the effectiveness of temperature-controlled thermal blanket as additional thermoprotection. DESIGN Randomized controlled prospective study. SETTING Single-center tertiary neonatal unit. PATIENTS Inborn very low-birth-weight (< 1,500 g) infants. INTERVENTIONS Infants were prospectively assigned to thermal blanket group or control at 1:1 ratio. Additional to radiant warmers, a prewarmed blanket of Blanketrol II (Cincinnati Sub-Zero Products, Cincinnati, OH) was applied as mattress for thermal blanket group. The outcomes included temperature and blood pressure changes. We defined hypothermia as temperature less than 36°C and hypotension as mean arterial pressure less than index infant's gestational age in weeks. MEASUREMENTS AND MAIN RESULT Total 80 very low-birth-weight infants were allocated, and there was no between-group demographic dissimilarity. At 30th minute, fewer infants in thermal blanket group were hypothermic (43% vs 68%; p = 0.025). These infants had significantly lower prevalence of hypotension, which associated with less dopamine use in the first 6 hours of life (25% vs 50%; p = 0.016). There was no hyperthermia more than 37.5°C episode. CONCLUSIONS By using thermal blanket to provide additional thermal protection for very low-birth-weight infants, the degree of hypothermia was improved, which related to fewer hypotensive cases and less dopamine usage.

Abstract
BACKGROUND Little is known about thermoregulation of the newborn while bonding on the mother's chest immediately after cesarean delivery. Newborn hypothermia is associated with serious complications and should be avoided. Therefore, we evaluated whether newborns develop hypothermia during intraoperative bonding while positioned on their mothers' chests and investigated the effects of active cutaneous warming of the mothers and babies during a 20-minute intraoperative bonding period. METHODS We enrolled 40 parturients scheduled for elective cesarean delivery under spinal anesthesia. Mothers and their newborns were randomized to receive either passive insulation or forced-air skin-surface warming during the surgical procedure and bonding period. The primary outcome was neonatal core temperature at the end of the bonding period. Core temperatures of the newborns were measured with a rectal probe. Body temperatures of the mothers were assessed by sublingual measurements. Skin temperatures, thermal comfort of the mothers, and perioperative shivering were evaluated. RESULTS Without active warming from the beginning of the surgical procedure until the end of the bonding period, the mean (SD) neonatal core temperature decreased to 35.9 (0.6)°C. Seventeen of 21 (81%) newborns became hypothermic (defined as a core temperature below 36.5°C). Active skin-surface warming from the beginning of the surgical procedure until the end of the bonding period resulted in a neonatal core temperature of 37.0 (0.2)°C and a decreased incidence of hypothermia (1 of 19 (5%) newborns (P < 0.0001)). In addition, active warming increased the mean skin temperatures of the infants, maternal core and skin temperatures, maternal thermal comfort, and reduced perioperative shivering. CONCLUSIONS Active forced-air warming of mothers and newborns immediately after cesarean delivery reduces the incidence of infant and maternal hypothermia and maternal shivering, and increases maternal comfort.

Abstract
Neonatal hypothermia, temperature < 36.5°C, is a major contributor to neonatal mortality and morbidity. hypothermia of preterm infants remains a challenge in the NiCU for many reasons. preterm very low birth weight (VlBW) infants, those infants born <1,500 g, are prone to very rapid heat losses through mechanisms of convection, evaporation, conduction, and radiation. this article reviews current research to reduce and prevent mortality and morbidity from hypothermia in preterm VlBW infants by implementing interventions in the delivery room to minimize heat loss and maintain core body temperatures.

Abstract
BACKGROUND Moderate hypothermia (temperature <36°C) at birth is common in premature infants and is associated with increased mortality and morbidity. METHODS A multidisciplinary practice plan was implemented to determine in premature infants <35 weeks old whether a multifaceted approach would reduce the number of inborn infants with an admitting axillary temperature <36°C by 20% without increasing exposure to a temperature >37.5°C. The plan included use of occlusive wrap a transwarmer mattress and cap for all infants and maintaining an operating room temperature between 21°C and 23°C. Data were obtained at baseline (n = 66), during phasing in (n = 102), and at full implementation (n = 193). RESULTS Infant axillary temperature in the delivery room (DR) increased from 36.1°C ± 0.6°C to 36.2°C ± 0.6°C to 36.6°C ± 0.6°C (P < .001), and admitting temperature increased from 36.0°C ± 0.8°C to 36.3°C ± 0.6°C to 36.7°C ± 0.5°C at baseline, phasing in, and full implementation, respectively (P < .001). The number of infants with temperature <36°C decreased from 55% to 6.2% at baseline versus full implementation (P < .001), and intubation at 24 hours decreased from 39% to 17.6% (P = .005). There was no increase in the number of infants with a temperature >37.5°C over time. The use of occlusive wrap, mattress, and cap increased from 33% to 88% at baseline versus full implementation. Control charts showed significant improvement in DR ambient temperature at baseline versus full implementation. CONCLUSIONS The practice plan was associated with a significant increase in DR and admitting axillary infant temperatures and a corresponding decrease in the number of infants with moderate hypothermia. There was an associated reduction in intubation at 24 hours. These positive findings reflect increased compliance with the practice plan.

Abstract
BACKGROUND AND OBJECTIVE Hypothermia during delivery room stabilization of very low birth weight (VLBW) newborns is independently associated with mortality, yet it occurred frequently both in collaborative networks and at our institution. We aimed to attain admission temperatures in the target range of 36 °C to 38 °C in ≥ 90% of inborn VLBW neonates through implementation of a thermoregulation bundle. METHODS This quality improvement project extended over 60 consecutive months, using sequential plan-do-check-act cycles. During the 14 baseline months, we standardized temperature measurements and developed the Operation Toasty Tot thermoregulation bundle (including consistent head and torso wrapping with plastic, warmed blankets, and a closed stabilization room). We introduced this bundle in month 15 and added servo-controlled, battery-powered radiant warmers for stabilization and transfer in month 21. We provided results and feedback to staff throughout, using simple graphics and control charts. RESULTS There were 164 inborn VLBW babies before and 477 after bundle implementation. Introduction and optimization of the bundle decreased the incidence of hypothermia, with rates remaining in the target range for the last 13 study months. The incidence of temperatures >38 °C was ~ 2% both before and after bundle implementation. CONCLUSIONS This thermoregulation bundle resulted in sustained improvement in normothermia rates during delivery room stabilization of VLBW newborns. Our benchmark goal of ≥ 90% admission temperatures above 36 °C was met without increasing hyperthermia rates. Because these results compare favorably with those of recently published research or improvement collaboratives, we aim to maintain our performance through routine surveillance of admission temperatures.

Abstract
Over the last 50 years an increasing amount of evidence on neonatal resuscitation and stabilisation practices has led to written recommendations on all aspects of newborn care in the first few minutes of life. Much evidence for thermoregulatory management of both term and preterm infants has existed for decades and more recently research has identified new techniques to maintain normothermia in newly born infants. The use of increased environmental temperatures, skin-to-skin care, radiant warmers, plastic coverings and hats, exothermic mattresses and heated humidified gases have or are undergoing evaluation. However, despite the apparent acceptance of these techniques, a substantial number of infants continue to become hypothermic soon after delivery, leading to an increased risk of comorbidities and of death. Gaps in our knowledge remain and further research opportunities are available. However, we must also ensure that established thermoregulatory methods for which the evidence already exists are given as much emphasis as other aspects of newborn care and are implemented meticulously in all healthcare settings.

Abstract
BACKGROUND AND OBJECTIVES Events in the delivery room significantly impact the outcomes of preterm infants. We developed evidence-based guidelines to prevent heat loss, reduce exposure to supplemental oxygen, and increase use of noninvasive respiratory support to improve the care and outcomes of infants with birth weight ≤1250 g at our institution. METHODS The guidelines were implemented through multidisciplinary conferences, routine use of a checklist, appointment of a dedicated resuscitation nurse, and frequent feedback to clinicians. This cohort study compares a historical group (n = 80) to a prospective group (n = 80, after guidelines were implemented). Primary outcome was axillary temperature at admission to the intensive care nursery. Secondary outcomes measured adherence to the guidelines and changes in clinically relevant patient outcomes. RESULTS Baseline characteristics of the groups were similar. After introduction of the guidelines, average admission temperatures increased (36.4°C vs 36.7°C, P < .001) and the proportion of infants admitted with moderate/severe hypothermia fell (14% vs 1%, P = .003). Infants were exposed to less oxygen during the first 10 minutes (P < .001), with similar oxygen saturations. Although more patients were tried on continuous positive airway pressure (40% vs 61%, P = .007), the intubation rate was not significantly different (64% vs 54%, P = .20). Median durations of invasive ventilation and hospitalization decreased after the quality initiative (5 vs 1 days [P = .008] and 80 vs 60 days [P = .02], respectively). CONCLUSIONS We have demonstrated significantly improved quality of delivery room care for very preterm infants after introduction of evidence-based delivery room guidelines. Multidisciplinary involvement and continuous education and reinforcement of the guidelines permitted sustained change.
