Abstract
OBJECTIVE Newborn hypothermia has been implicated in neonatal morbidity without randomized evidence that it compromises the infant. Our objective was to determine if a difference in operating room temperature at cesarean birth impacts neonatal morbidity. STUDY DESIGN Women undergoing cesarean delivery of a liveborn infant without major malformations were included. The institutional preexisting operating room temperature of 20°C (67°F) was compared with an experimental group of 24°C (75°F) by cluster randomization assigned on a weekly basis. Newborn hypothermia was defined as axillary temperature on arrival to the nursery of less than 36.5°C (<97.7°F). The primary outcome was a composite of neonatal morbidity including respiratory support, sepsis, hypoglycemia, and neonatal death. RESULTS Between November 2016 and May 2018, 5,221 women had cesarean deliveries at Parkland Hospital with 2,817 randomized to the standard care group and 2,404 to the experimental group. The rate of neonatal composite morbidity did not differ between the groups: standard care 398 (14%) versus experimental 378 (16%), p = 0.11. This was despite a significant decrease in the rate of neonatal hypothermia: standard care 1,195 (43%) versus experimental 414 (18%), p < 0.001. There was no difference in the composite outcome for preterm infants (<37 wk) between the groups: standard care 194 (49%) versus experimental 185 (54%), p = 0.25. CONCLUSION An 8°F increase in operating room temperature was significantly associated with a reduced rate of neonatal hypothermia, although this decrease was not associated with a significant improvement in neonatal morbidity. However, the increase in operating room temperature was met with resistance from obstetricians and operating room personnel. This trial is registered (registration no.: NCT03008577).

Abstract
BACKGROUND Hyperthermia is a known risk for sudden unexpected infant death. The practice of hat placement at birth to prevent transient hypothermia may not be necessary and sets an early standard for clothing infants that may lead to hyperthermia postnatally. OBJECTIVE To examine the elimination of hats on thermoregulation (eg, hypothermia, <97.6°F) in full-term newborns with no abnormalities within 24 hours of birth. METHODS In 2018, an institution guideline discontinued the use of hats at birth. Subsequently, newborn body temperatures were respectively extracted from electronic health records and data were compared from 482 infants (>38 weeks' gestation and newborn birth weight >2500 g) prior to ( n = 257) and following ( n = 225) the practice change. Body temperatures prior to and after the practice change to eliminate hats use were compared. RESULTS No statistically significant difference was observed: (1) in the proportion of infants experiencing hypothermia with or without hat use, respectively, 23.7% compared with 31.1% ( P = .09) and (2) in the odds of an infant experiencing hypothermia when adjusting for relevant covariates (odds ratio = 1.44; 95% confidence interval 0.89-2.32; P = .14). CONCLUSIONS Our findings demonstrate that the use of hats on infants at birth had no measurable impact on newborn thermoregulation.

Abstract
OBJECTIVE To compare two polyethylene bags in preventing admission hypothermia in preterm infants born at <34 weeks gestation. METHOD Quasi-randomized unblinded clinical trial conducted at a level III neonatal unit between June 2018 to September 2019. The authors assign infants between 240/7 and 336/7 weeks' gestation to receive NeoHelp™ bag (intervention group) or a usual plastic bag (control group). The primary outcome was admission hypothermia, considering an axillary temperature at admission to the neonatal unit of <36.0 °C. Hyperthermia was considered if the admission temperature reached 37.5 °C or more. RESULTS The authors evaluated 171 preterm infants (76, intervention group; 95, control group). The rate of admission hypothermia was significantly lower in the intervention group (2.6% vs. 14.7%, p = 0.007), with an 86% reduction in the admission hypothermia rate (OR, 0.14; 95% CI, 0.03-0.64), particularly for infants weighing >1000 g and >28 weeks gestation. The intervention group also had a higher median of temperature at admission - 36.8 °C (interquartile range 36.5-37.1) vs. 36.5 °C (interquartile range 36.1-36.9 °C), p = 0.001, and showed a higher hyperthermia rate (9.2% vs. 1.0%, p = 0.023). Birth weight was also associated to the outcome, and it represented a 30% chance reduction for every 100-g increase (OR, 0.997; 95% CI, 0.996-0.999). The in-hospital mortality rate was similar between groups. CONCLUSION The intervention polyethylene bag was more effective in preventing admission hypothermia. Nonetheless, the risk of hyperthermia is a concern during its use.

Reducing Admission Hypothermia in Neonates Born at Less Than 32 Weeks or 1500 g. Adv Neonatal Care 2022; 22:99-107. [PMID: 33783381 DOI: 10.1097/anc.0000000000000865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
PURPOSE The purpose of this quality improvement project was to decrease admission hypothermia in neonates born at less than 32 weeks or less than 1500 g. METHODS At delivery, neonates born less than 1500 g or at less than 32 weeks received polyurethane bags, polyurethane hats, and chemical mattresses. New practice guidelines from 2016 promoted this practice for all neonates born at less than 32 weeks, but the authors' prior work indicated that all neonates born less than 1500 g were at risk (regardless of gestational age) and would benefit from these interventions. FINDINGS/RESULTS After the intervention, only 2.1% (n = 2) of neonates born less than 1500 g or at less than 32 weeks were admitted moderately hypothermic (<36°C) compared with 9.6% in 2016, 20.2% in 2015, and 32.4% in 2014. Overall, the mean admission temperature in 2017 was 37°C, improved from 36.6°C in 2016, 36.3°C in 2015, and 36.2°C in 2014 (P < .001). IMPLICATIONS FOR PRACTICE The intervention significantly reduced the number of neonates admitted moderately hypothermic (<36.0°C) to this neonatal intensive care unit. Using chemical mattresses and polyurethane bags with neonates born less than 1500 g or at less than 32 weeks (compared with only <1000 g) improved admission temperatures. It is important to include all neonates born less than 1500 g in these practice interventions and not only those born at less than 32 weeks; both gestational age and weight should guide practice. IMPLICATIONS FOR RESEARCH More research is needed on the effects of thermoregulation interventions and hyperthermia in neonates, as well as best practice thermoregulation interventions for preterm and ill neonates of all gestational ages and weights.

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 determine whether early polyethylene bag use with skin-to-skin care compared with skin-to skin care alone reduce hypothermia among infants born at term in resource-limited settings. STUDY DESIGN Infants born at term in the tertiary referral center in Lusaka, Zambia, were randomized using sequentially numbered sealed opaque envelopes in 2 phases: after birth (phase 1) and at 1 hour after birth (phase 2) to either skin-to-skin care with polyethylene bags or skin-to-skin care alone. Infant and maternal temperatures were recorded at birth, 1 hour, and every 4 hours until discharge or 24 hours. RESULTS We enrolled 423 infants from May 2017 to August 2017. The rate of moderate-severe hypothermia (temperature <36.0°C) at 1 hour was 72 of 208 (34.6%) in the skin-to-skin care with a polyethylene bag group compared with 101 of 213 (47.4%) in the skin-to-skin care alone group (relative risk, 0.71; 95% CI 0.56-0.90; P < .01; number needed to treat = 8). phase 1 treatment assignment significantly modified the effect of phase 2 treatment (P = .02 for interaction effect). Among infants randomized to skin-to-skin care with a polyethylene bag in phase 1, the risk of moderate-severe hypothermia was decreased in infants randomized to continue this intervention until discharge compared with infants randomized to skin-to-skin care alone. The rates of severe hypothermia, hyperthermia, and other adverse events did not differ significantly between groups. CONCLUSIONS Low-cost polyethylene bags started after birth in combination with skin-to-skin care reduced moderate or severe hypothermia at 1 hour and at discharge among infants born at term in a resource-limited setting compared with skin-to-skin care alone.

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
BACKGROUND Mobile intensive care units frequently manage unplanned out-of-hospital births (UOHB). Rewarming methods during pre-hospital management of UOHB have not yet been compared. The aim was to compare rewarming methods used during pre-hospital management in a large prospective cohort of UOHB in France. METHODS We analysed UOHB from the prospective AIE cohort from 25 prehospital emergency medical services in France. The primary outcome was the change in body temperature from arrival at scene to arrival at hospital. RESULTS From 2011 to 2018, 1854 UOHB were recorded, of whom 520 were analysed. We found that using incubator care was the most effective rewarming method (+ 0.8 °C during transport), followed by the combination of plastic bag, skin-to-skin and cap (+ 0.2 °C). The associations plastic bag + cap and skin-to-skin + cap did not allow the newborn to be warmed up but rather to maintain initial temperature (+ 0.0 °C). The results of the multivariate model were consistent with these observations, with better rewarming with the use of an incubator. We also identified circumstances of increased risk of hypothermia according to classification and regression tree, like premature birth (< 37 weeks of gestation) and/or low outside temperature (< 8.4 °C). CONCLUSIONS Using an incubator was the most effective rewarming method during pre-hospital management of UOHB in our French prospective cohort. Based on our model, in cases of term less than 37 weeks of gestation or between 37 and 40 weeks with a low outside temperature or initial hypothermia, using such a method would be preferred.

Donnellan D, Moore Z, Patton D, O'Connor T, Nugent L. 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. J SPEC PEDIATR NURS 2020; 25:e12286. [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.

Physiologic-Based Cord Clamping Maintains Core Temperature vs. Immediate Cord Clamping in Near-Term Lambs. Front Pediatr 2020; 8:584983. [PMID: 33194919 PMCID: PMC7644840 DOI: 10.3389/fped.2020.584983] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Accepted: 09/16/2020] [Indexed: 11/13/2022] Open
Abstract
Background: Physiologic-based cord clamping (PBCC) involves deferring umbilical cord clamping until after lung aeration. It is unclear if infant is at risk of becoming hypothermic during PBCC. Objectives: To test if PBCC would maintain core temperature more effectively than immediate cord clamping (ICC). Design: At 0.93 gestation, fetal lambs were surgically exteriorized and instrumented from pregnant ewes under general anesthesia. Prior to the start of the experiment, lambs were thoroughly dried, placed on hot water bottles, and core temperature was continuously monitored using a rectal thermometer. PBCC lambs (n = 21), received intermittent positive pressure ventilation (iPPV) for ≥5 min prior to umbilical cord clamping. In ICC lambs (n = 23), iPPV commenced within 60 s after umbilical cord clamping. iPPV was provided with heated/humidified gas. Lambs were moved under a radiant warmer after umbilical cord clamping. Additional warmth was provided using a plastic overlay, hairdryer, and extra water bottles, as needed. Two-way mixed and repeated measures one-way ANOVAs were used to compare temperature changes between and within a single group, respectively, over time. Results: Basal fetal parameters including core temperature were similar between groups. ICC lambs had a significant reduction in temperature compared to PBCC lambs (p < 0.001), evident by 1 min (p = 0.002). ICC lambs decreased temperature by 0.51°C (± 0.42) and 0.79°C (± 0.55) at 5 and 10 min respectively (p < 0.001). In PBCC lambs, temperature did not significantly change before or after umbilical cord clamping (p = 0.4 and p = 0.3, respectively). Conclusions: PBCC stabilized core temperature at delivery better than ICC in term lambs. Hypothermia may not be a significant risk during PBCC.

Abstract
Objetivo: identificar estratégias para a prevenção de lesões de pele em recém-nascidos (RN) hospitalizados, publicadas em periódicos científicos no período de 2013 a 2018. Método: revisão integrativa de literatura realizada em dois momentos de busca em bases de dados, sendo selecionados 37 estudos publicados entre os anos de 2013 e 2018. Resultados: termorregulação, uso de antisséptico, uso de emolientes e limpeza do coto umbilical foram as recomendações mais encontradas. Entre as práticas baseadas em evidência, destacam-se as que previnem o risco de hipotermia, como o uso de saco de polietileno e o contato pele a pele, que respaldam a assistência e que garantem segurança no cuidado do paciente neonatal. Conclusão: a prevenção de lesões de pele é um tema relevante, entretanto, existe escassez de evidências robustas para sustentar, com segurança, as práticas de cuidados com o RN. Observa-se ainda que as evidências são insuficientes para englobar o universo do tema, demonstrando que o cuidado com a pele é um tema que demanda investimentos e mais pesquisas.

Abstract
Objective: To identify strategies for the prevention of skin lesions in hospitalized newborns (NBs), published in scientific journals from 2013 to 2018. Method: Integrative literature review performed in two moments of database search, selecting 37 studies published between 2013 and 2018. Results: Thermoregulation, use of antiseptic, use of emollients and cleaning of the umbilical stump were the most commonly found recommendations. Among the evidence-based practices, we highlight those that prevent the risk of hypothermia, such as the use of a polyethylene bag and skin-to-skin contact, which support the assistance and ensure safety in the care of the neonatal patient. Conclusion: The prevention of skin lesions is a relevant topic. However, there is a scarcity of robust evidence to safely sustain NB care practices. It is also observed that the evidence is insufficient to encompass the universe of the theme, demonstrating that skin care is a theme that requires investment and more research.

Significant factors influencing inadvertent hypothermia in pediatric anesthesia. J Clin Monit Comput 2019; 33:1105-1112.

Abstract
Thermal imbalances are very common during surgery. Hypothermia exposes the patient to post-operative shivering, cardiac dysfunction, coagulopathy, bleeding, wound infection, delayed anesthesia recovery, prolonged hospital stay and increased hospitalization cost. There are many factors contributing to intraoperative hypothermia. This is a prospective cohort study conducted through observation and measurement of pediatric surgical patients' temperature. Convenience sampling methods were used in this study. Initial skin temperature and core temperature at 10 min, 30 min,1 h, 2 h, 3 h, 4 h, 5 h, 6 h and at the end of surgery were recorded. Body temperature was monitored from time of transfer to the operating table until recovery and discharge to the respective pediatric ward. The overall incidence of intraoperative hypothermia was still very high at about 46.6% even though active and passive temperature management were carried out during surgery. Patient's age, body weight, duration of surgery, type of surgery, intraoperative blood loss, type of anesthesia and operating room temperature were factors that contributed to intraoperative hypothermia. Hypothermia is common in surgery, especially in major and long duration surgery. Intraoperative hypothermia can be life threatening if it is not handled carefully. Various methods are used before, during and after surgery to maintain a patient's body temperature within the normothermia range. The use of an active warming device like the Bair Hugger® air-forced warming system seems to be a good method for reducing the risk of intraoperative hypothermia and effectively maintaining body temperature for all major and minor surgeries.

Abstract
Background: The current resuscitation guidelines recommend frequent simulation based medical education (SBME). However, the current SBME approach is expensive, time-intensive, and requires a specialized lab and trained instructors. Hence, it is not offered routinely at all hospitals. We designed the board game "RETAIN" to train healthcare providers (HCPs) in neonatal resuscitation in a cost-friendly and accessible way. Objectives: To examine if a board game-based training simulator improves knowledge retention in HCPs. Methods: "RETAIN" consists of a board using an image of a baby, visual objects, adjustable timer, monitors, and action cards. Neonatal HCPs at the Royal Alexandra Hospital were invited to participate. Participants completed a written pre-test (resuscitation of a 24-week infant), then played the board game (starting with a tutorial followed by free playing of three evidence-based neonatal resuscitation scenarios). Afterwards, a post-test with the same resuscitation scenario and an opinion survey was completed. The answers from the pre- and post-test were compared to assess HCPs' knowledge retention. Results: Thirty HCPs (four doctors, 12 nurses, and 14 respiratory therapist) participated in the study. Overall, we observed a 10% increase in knowledge retention between the pre- and post-test (49-59%, respectively). Temperature management showed the most knowledge gain between the pre- and post-test (14-46%, respectively). Placement of a hat (10-43%), plastic wrap (27-67%), and temperature probe (7-30%) improved between the pre- and post-test. Conclusion: Knowledge retention increased by 12% between pre- and post-test (49-61%, respectively). The improvement in performance and knowledge supports the use of board game simulations for clinical training.

Abstract
OBJECTIVE To study the effect of golden-hour body temperature bundle management strategy on admission temperature and clinical outcome in preterm infants with a gestational age of <34 weeks after birth. METHODS The preterm infants who were born in the delivery room of the West China Second University Hospital of Sichuan University and admitted to the department of neonatology of this hospital within 1 hour after birth from December 2015 to June 2016 and from January to May, 2017 were enrolled. The 173 preterm infants who were admitted from January to May, 2017 were enrolled as the intervention group and were given golden-hour body temperature bundle management. The 164 preterm infants who were admitted from December 2015 to June 2016 were enrolled as the control group and were given conventional body temperature management. RESULTS The intervention group had a significantly higher mean admission temperature than the control group (36.4±0.4°C vs 35.3±0.6°C; P<0.001). The incidence rate of hypothermia on admission in the intervention group was significantly lower than that in the control group (56.6% vs 97.6%; P<0.001). The intervention group had a significantly lower incidence rate of intracranial hemorrhage within one week after admission than the control group (15.0% vs 31.7%; P<0.05). CONCLUSIONS Golden-hour body temperature bundle management for preterm infants within one hour after birth can reduce the incidence of hypothermia on admission and improve clinical outcome.

Abstract
AIM This study investigated the different strategies used in 11 European countries to prevent hypothermia, which continues to affect a large proportion of preterm births in the region. METHODS We examined the association between the reported use of hypothermia prevention strategies in delivery rooms and body temperatures on admission to neonatal intensive care units (NICUs) in 5861 infants born at 22 + 0 to 31 +6 weeks of gestation. The use of plastic bags, wraps, caps, exothermic heat and mattresses was investigated. RESULTS The proportion of infants born in units that systematically used one or more hypothermia prevention strategies was 88.2% and 50.9% of those infants were hypothermic on admission to NICUs. Of the 9.6% born in units without systematic hypothermia prevention, 73.2% were hypothermic. Only 2.2% of infants were born in units with no reported prevention strategies. Lower gestational age increased the probability of hypothermia. No significant differences were found between the various hypothermia prevention strategies. Hyperthermia was seen in 4.8% of all admitted infants. CONCLUSION Very preterm infants had lower risks of hypothermia on NICU admission if the unit used systematic prevention strategies. All the strategies had similar effects, possibly due to implementation rather than a strategy's specific efficacy.

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
AIM This study investigated the association between hypothermia and respiratory distress syndrome (RDS), bronchopulmonary dysplasia (BPD) or death in very preterm infants admitted to a Danish neonatal intensive care unit (NICU). METHODS We studied 675 infants born at Aalborg University Hospital before 32 weeks and admitted to the NICU from April 1997 to December 2011. Hypothermia was defined as a core temperature of <36.5°C on admission. The primary outcome was severe RDS or death within the first three days of life, and the secondary outcome was BPD or death before 36 postmenstrual weeks. The multivariable logistic regression was adjusted for early-onset infection, gestational age, Apgar score, sex, treatment year and birth weight. RESULTS Infants with hypothermia had a twofold increase (OR) in the odds for RDS or death (2.03), but the adjusted OR was not statistically significant (1.36). They also demonstrated a twofold increase (OR) in the odds for BPD or death (2.28), but again the adjusted OR was not statistically significant (1.03). CONCLUSION After adjusting for confounders, we found that the association between hypothermia on admission to the NICU and RDS or death, or BPD or death was statistically insignificant.

Abstract
"Golden Hour" of neonatal life is defined as the first hour of post-natal life in both preterm and term neonates. This concept in neonatology has been adopted from adult trauma where the initial first hour of trauma management is considered as golden hour. The "Golden hour" concept includes practicing all the evidence based intervention for term and preterm neonates, in the initial sixty minutes of postnatal life for better long-term outcome. Although the current evidence supports the concept of golden hour in preterm and still there is no evidence seeking the benefit of golden hour approach in term neonates, but neonatologist around the globe feel the importance of golden hour concept equally in both preterm and term neonates. Initial first hour of neonatal life includes neonatal resuscitation, post-resuscitation care, transportation of sick newborn to neonatal intensive care unit, respiratory and cardiovascular support and initial course in nursery. The studies that evaluated the concept of golden hour in preterm neonates showed marked reduction in hypothermia, hypoglycemia, intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), and retinopathy of prematurity (ROP). In this review article, we will discuss various components of neonatal care that are included in "Golden hour" of preterm and term neonatal care.

Abstract
PURPOSE Children undergoing operative intervention while induced under general anesthesia are at risk for experiencing a significant decrease in core body temperature that can lead to adverse systemic effects. Given that the head contributes an estimated 18% of a child's body surface area, we theorized that a liquid-warming garment applied to the head could control a pediatric patient's core body temperature during surgical procedures. METHODS Patients undergoing elective, non-cranial, general surgical procedures were enrolled in the study. A head garment with an embedded network of tubing was placed on the patient. The garment connected to a computer-controlled water bath that managed the temperature of the water in the tubing through a feedback mechanism. RESULTS Ten patients with ages ranging from 1 day to 3 years (mean age 10.5 months) were enrolled in this study. The average procedure length was 82.5 min. The mean core body temperature throughout the procedure for all-comers was 36.5 ± 0.9 °C with an overall mean difference in maximum and minimum temperatures of 1.32 ± 1.1 °C. CONCLUSION A liquid-warming garment applied to the head of pediatric surgical patients is an innovative and relatively low-cost means to regulate and to maintain the ideal core body temperature of patients undergoing surgical procedures.

Abstract
The concept of "Golden 60 minutes" or "Golden Hour" has been derived from adult trauma. It has been defined as the first 60 min of postnatal life. It has been seen that care received by any newborn in the initial first hour has implications in the future life, showing the importance of golden hour. The major cause of neonatal mortality term newborn is asphyxia, which can be reduced with effective resuscitation. In golden hour approach for term newborn, the importance is given to effective and evidence based resuscitation, post-resuscitation care, delayed cord clamping, prevention of hypothermia, immediate breast feeding, prevention of hypoglycemia, and starting of therapeutic hypothermia in case of moderate to severe asphyxia. In this part of review, we will cover all the golden hour interventions in term neonate with current evidence.
