Early detection of cold stress to prevent hypothermia: A narrative review.

Temperature monitoring is essential for assessing neonates and providing appropriate neonatal thermal care. Thermoneutrality is defined as the environmental temperature range within which the oxygen and metabolic consumptions are minimum to maintain normal body temperature. When neonates are in an environment below thermoneutral temperature, they respond by vasoconstriction to minimise heat losses, followed by a rise in metabolic rate to increase heat production. This condition, physiologically termed cold stress, usually occurs before hypothermia. In addition to standard axillary or rectal temperature monitoring by a thermometer, cold stress can be detected by monitoring peripheral hand or foot temperature, even by hand-touch. However, this simple method remains undervalued and generally recommended only as a second and lesser choice in clinical practice. This review presents the concepts of thermoneutrality and cold stress and highlights the importance of early detection of cold stress before hypothermia occurs. The authors suggest systematic clinical determination of hand and foot temperatures by hand-touch for early detection of physiological cold stress, in addition to monitoring core temperature for detection of established hypothermia, particularly in low-resource settings.

Neonatal warming devices: What can be recommended for low-resource settings when skin-to-skin care is not feasible?

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

2.5 Million Annual Deaths-Are Neonates in Low- and Middle-Income Countries Too Small to Be Seen? A Bottom-Up Overview on Neonatal Morbi-Mortality.

(1) Background: Every year, 2.5 million neonates die, mostly in low- and middle-income countries (LMIC), in total disregard of their fundamental human rights. Many of these deaths are preventable. For decades, the leading causes of neonatal mortality (prematurity, perinatal hypoxia, and infection) have been known, so why does neonatal mortality fail to diminish effectively? A bottom-up understanding of neonatal morbi-mortality and neonatal rights is essential to achieve adequate progress, and so is increased visibility. (2) Methods: We performed an overview on the leading causes of neonatal morbi-mortality and analyzed the key interventions to reduce it with a bottom-up approach: from the clinician in the field to the policy maker. (3) Results and Conclusions: Overall, more than half of neonatal deaths in LMIC are avoidable through established and well-known cost-effective interventions, good quality antenatal and intrapartum care, neonatal resuscitation, thermal care, nasal CPAP, infection control and prevention, and antibiotic stewardship. Implementing these requires education and training, particularly at the bottom of the healthcare pyramid, and advocacy at the highest levels of government for health policies supporting better newborn care. Moreover, to plan and follow interventions, better-quality data are paramount. For healthcare developments and improvement, neonates must be acknowledged as humans entitled to rights and freedoms, as stipulated by international law. Most importantly, they deserve more respectful care.

Ending Neonatal Deaths From Hypothermia in Sub-Saharan Africa: Call for Essential Technologies Tailored to the Context.

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

Clinical detection of 'cold stress' is overlooked: an online survey of healthcare workers to explore the gap in neonatal thermal care in low-resource settings.

BACKGROUND: Neonatal hypothermia has been widely regarded as a major contributory factor to neonatal mortality and morbidity in low-resource settings. The high prevalence of potentially preventable hypothermia today urges an investigation into why neonates still become hypothermic despite awareness of the problem and established thermal care guidelines. This study aimed to explore the gaps in knowledge and practices of neonatal thermal care among healthcare workers in low-resource settings. METHODS: A cross-sectional, questionnaire-based survey was performed online among healthcare workers in low-resource settings. We applied a purposive and snowballing sampling method to recruit participants through a two-round international online survey. Questionnaires were developed using themes of neonatal thermal care extracted from existing neonatal care guidelines. RESULTS: 55 neonatal care professionals participated in the first-round survey and 33 in the second. Almost all participants (n=44-54/55) acknowledged the importance of the WHO's warm chain to keep a neonate warm. However, fewer participants (n=34-46/55) responded to practice them. When asked about cold stress, defined as a condition in which neonates are below optimum environmental temperature and using more oxygen and energy while maintaining normal body temperature, 15 out of 55 participants answered that checking extremity temperatures by hand touch was useless. Some participants reported concern about the extremity temperature's inaccuracy compared with core temperature. Opinions and preferences for rewarming methods differed among participants, and so did the availability of warming equipment at their institutions. CONCLUSION: An inadequate understanding of cold stress underestimates the potential benefits of extremity temperatures and leads to missed opportunities for the timely prevention of hypothermia. The current thermal care guidelines fail to highlight the importance of monitoring cold stress and intervening before hypothermia occurs. Therefore, we urge introducing the concept of cold stress in any neonatal thermal care guidelines.

Safety of Red Blood Cell Transfusion Using Small Central Lines in Neonates: An in vitro Non-inferiority Study.

Aim: This study aimed to investigate the safety of transfusing red blood cell concentrates (RBCCs) through small [24 gauge (24G)] and extra-small [28 gauge [28G)] peripherally inserted central catheters (PICCs), according to guidelines of transfusion practice in Switzerland. Methods: We performed a non-inferiority in vitro study to assess the safety of transfusing RBCC for 4 h at a 4 ml/h speed through 24G silicone and 28G polyurethane PICC lines, compared with a peripheral 24G short catheter. The primary endpoint was hemolysis percentage. Secondary endpoints were catheter occlusion, inline pressure, and potassium and lactate values. Results: For the primary outcome, hemolysis values were not statistically different among catheter groups (0.06% variation, p = 0.95) or over time (2.75% variation, p = 0.72). The highest hemolysis values in both 24G and 28G PICCs were below the non-inferiority predefined margin. We did not observe catheter occlusion. Inline pressure varied between catheters but followed the same pattern of rapid increase followed by stabilization. Potassium and lactate measurements were not statistically different among tested catheters (0.139% variation, p = 0.98 for potassium and 0.062%, p = 0.96 for lactates). Conclusions: This study shows that RBCC transfusion performed in vitro through 24G silicone and 28G polyurethane PICC lines is feasible without detectable hemolysis or pressure concerns. Also, it adds that, concerning hemolysis, transfusion of RBCC in small and extra-small PICC lines is non-inferior to peripheral short 24G catheters. Clinical prospective assessment in preterm infants is needed to confirm these data further.

Associations between Red Blood Cell and Platelet Transfusions and Retinopathy of Prematurity.

AIM: The aim of this study is to examine possible associations between the transfusion of RBC or platelets (PLTs) and the development of retinopathy of prematurity (ROP) in infants. METHODS: This retrospective, national, case-control study included all live births in Switzerland between 2013 and 2018. We investigated preterm infants at a gestational age of <28 weeks, who developed higher stage ROP (≥stage 2, n = 178). Each case infant was matched to another of the same sex who did not develop ROP (n = 178, control group). RESULTS: When compared with the control group, we observed higher numbers of RBC transfusions per infant and higher percentages of infants receiving PLT transfusions in the case group. An adjusted logistic regression analysis revealed that both RBC (odds ratio [OR] 1.081, 95% confidence interval [CI] 1.020-1.146) and PLT transfusions (OR = 2.502, 95% CI 1.566-3.998) numbers were associated with ROP development. CONCLUSIONS: Multiple RBC and PLT transfusions are associated with higher stage ROP development. Prospective studies are required to determine their potential as risk factors.

Hypothermia in Preterm Newborns: Impact on Survival.

Background. Globally, prematurity is the leading cause of neonatal mortality, and hypothermia is one of its contributing factors. The goal of this study was to determine the association between hypothermia and mortality. Methods. A prospective, multi-center, descriptive clinical study was conducted in 5 hospitals in Ethiopia. Axillary temperatures were taken at the time of admission to the newborn intensive care units (NICU) and followed during the NICU stay. Results. A total of 3852 premature neonates (<37 weeks) were admitted to the NICUs from July 2016 to May 2018. Of these infants, 1109 (28.8%) died and 2991 (79.6%) had hypothermia. Hypothermia was associated with perinatal asphyxia (89.5%), RDS (86.2%), and resuscitation at birth (82.7%). Admission temperatures in preterm newborns were inversely associated with mortality and morbidity. Conclusion. Hypothermia at admission is associated with neonatal mortality in premature neonates in Ethiopia. RDS and perinatal asphyxia were the main factors associated with hypothermia. The very high prevalence and association with mortality warrants quality improvement interventions.

Post-Burn Infantile Hemangioma in an Extremely Premature Neonate.

Infantile hemangioma (IH) is the most common vascular tumor in infancy, and its physiopathology is not fully understood. Nevertheless, a hypoxic insult may be an essential element for the formation of an IH. Herein, we describe a case of a 25-week premature newborn who developed an IH after a post-burn scar and its evolution.

Successful conservative treatment of intestinal perforation in VLBW and ELBW neonates: a single centre case series and review of the literature.

BACKGROUND: The current standard treatment of neonates with intestinal perforation is surgery. However, the mortality rate after surgical treatment for intestinal perforation is very high for very low birth weight (VLBW) and extremely low birth weight (ELBW) neonates. In this review, conservative treatment of pneumoperitoneum among VLBW and ELBW neonates is investigated. METHODS: Between January 2015 and December 2017, data from all of the VLBW and ELBW neonates with pneumoperitoneum who survived without surgical treatment were collected from Shenzhen Maternity and Child Healthcare Hospital in Guangdong, China. Twenty-two neonates with birth weight less than 1500 g were diagnosed with pneumoperitoneum. Following careful evaluation and discussion, eleven were treated conservatively and this was successful in eight. Details of the eight neonates including birth weight, gestational age, gender, risk factors, time of the perforation, treatment and prognosis were retrospectively recorded. A literature review was performed of previously reported cases that had used conservative treatment. RESULTS: The median gestational age and birth weight of the eight neonates were 27+ 1 weeks (range 24w+ 3 to 31w+ 6) and 855 g (range 650 g to 1440 g), respectively. Pneumoperitoneum was confirmed by X-ray in all at a median of 8 days of life. They received full parenteral support for a median of 22 days. All eight neonates received a combination of piperacillin-tazobactam and meropenem as first-choice antibiotics, two of them also received fluconazole as anti-fungal medication. Median duration of hospitalisation was 80 days. CONCLUSIONS: Conservative treatment with careful surveillance may be a practical choice for the VLBW and ELBW neonates with intestinal perforation. Further studies are needed for confirmation.

Neurodevelopmental outcome at early school age in a Swiss national cohort of very preterm children.

BACKGROUND: Infants born very preterm are at higher risk of long-term neurodevelopmental problems than children born at term. Although there are increasing numbers of reports on outcomes from international cohorts of premature infants, a Swiss national report on infants after 2 years of age is lacking. AIMS OF THE STUDY: To describe neurodevelopmental outcomes at early school age of preterm children born in Switzerland with a special focus on the cognitive abilities. METHODS: This prospective national cohort study included children born alive before 30 weeks of gestation in 2006. At 5 years of age, children underwent a neurological examination and intelligence testing with the Kaufman Assessment Battery for Children first edition (K-ABC). We assessed the mental processing composite score (MPC) and its subscales to explore specific cognitive deficits. The primary outcome was cognitive impairment (MPC score <-1 standard deviation from the normative mean), motor impairment (cerebral palsy), or sensory impairment (any visual or hearing deficiency). The need for early intervention or therapies and the association of perinatal factors with cognitive impairment were secondary and tertiary outcomes. Logistic regression models were used to analyse associations between neonatal factors and cognitive outcome. RESULTS: Of 289 survivors, 235 were assessed. Of the 199 children with results obtained from the K-ABC, 42 (21%) showed cognitive impairment and 80 (40%) showed impairment in short-term memory. Cerebral palsy was diagnosed in 14 (6%), and visual and auditory impairment in 36 (15%) and 12 (5%) children, respectively; 63 (27%) needed early intervention or therapies. Cognitive impairment was associated with low socioeconomic status, but not with gestational age, small birthweight for gestational age, bronchodysplasia, or significant brain injury. A total of 146 children (63%) survived without any impairment. CONCLUSION: This is the first study to report neurodevelopmental outcomes at early school age in a Swiss cohort. The majority had favourable outcomes, but 21% of children demonstrated cognitive impairment, which was most pronounced in short-term memory. Our findings were similar to those of international cohorts and indicate that preterm children born before 300/7 gestational weeks, especially those living in unfavourable social environments, are at an increased risk of cognitive impairment and need close monitoring beyond early school age.

Prediction of ROP Treatment and Evaluation of Screening Criteria in VLBW Infants-a Population Based Analysis.

BACKGROUND: The incidence of retinopathy of prematurity (ROP) and ROP screening criteria differ between countries. We assessed whether ROP screening could be reduced based on the local ROP incidence. METHODS: Observational cohort study of infants born in Switzerland between 2006 and 2015 <32 0/7 weeks. Chronological and postmenstrual ages at ROP treatment were analyzed. A model to identify ROP treatment on patients born between 2006 and 2012 (training set) was developed and tested on patients born between 2013 and 2015 (validation set). RESULTS: Of 7817 live-born infants, 1098 died within the first 5 weeks of life. The remaining 6719 infants were included into analysis. All patients requiring ROP treatment would have been identified if screening had been performed before reaching 60 days of life or 37 3/7 weeks postmenstrual age, whichever came first. The training and validation sets included 4522 and 2197 preterm infants encompassing 56 and 20 patients receiving ROP treatment, respectively. All patients would have required screening to reach 100% sensitivity. To reach a sensitivity of 95.0% and a specificity of 87.6%, we predicted a reduction in 13.2% of patients requiring screening (c-statistic = 0.916). CONCLUSIONS: A substantial reduction of infants requiring screening seems possible, but necessitates prospective testing of new screening criteria.

[Obstetrics]. / Obstétrique.

During the past year, we have renewed interest in old well-known problems. New studies and guidelines have been issued about lung maturation in cases of preterm delivery after 37 weeks of gestation. Short term benefits have been proven but the number of cases needed to treat to prevent one case of respiratory complications is high and with possible neurological long-term effects. Also, several studies have shown the benefits of including the ultrasound measurement of the inferior segment of the uterus in order to attempt vaginal delivery after caesarean section with the lowest risk for uterine rupture, while others studies have shown the best procedure to close the uterus during cesarean section. And finally, we will discuss about an old friend: aspirin to reduce the risk of pre-eclampsia.

Au cours de l'année écoulée, l'intérêt pour de vieux problèmes bien connus de notre spécialité médicale a été renouvelé. De nouvelles études et lignes directrices ont été publiées concernant la maturation pulmonaire en cas d'accouchement prématuré après 37 semaines de gestation. Bien qu'un bénéfice à court terme ait été prouvé, le nombre de cas à traiter pour prévenir une complication respiratoire néonatale est élevé, avec des effets neurologiques potentiels à long terme. Afin de promouvoir la tentative d'accouchement vaginal après césarienne sans augmenter le risque de rupture utérine, différents travaux indiquent qu'il faut intégrer la mesure du segment inférieur de l'utérus dans la discussion de la voie d'accouchement. D'autres ont montré la meilleure procédure pour fermer l'utérus pendant la césarienne. Enfin, nous allons parler d'une vieille amie : l'aspirine pour réduire le risque de prééclampsie.

Incidence of retinopathy of prematurity (ROP) and ROP treatment in Switzerland 2006-2015: a population-based analysis.

BACKGROUND: Retinopathy of prematurity (ROP) is a severe complication of preterm birth and can lead to severe visual impairment or even blindness if untreated. The incidence of ROP requiring treatment is increasing in some developed countries in conjunction with higher survival rates at the lower end of gestational age (GA). MATERIAL AND METHODS: The incidence of ROP and severe ROP (sROP) requiring treatment in Switzerland was analysed using the SwissNeoNet registry. We conducted a retrospective cohort analysis of very preterm infants with a GA below 32 weeks who were born between 2006 and 2015 in Switzerland. Patient characteristics were stratified according to GA. RESULTS: 9.3% and 1.8% of very preterm infants in Switzerland developed ROP of any stage and sROP, respectively. The incidence of ROP treatment was 1.2%. Patients with 24 and 25 weeks GA had the highest proportion of ROP treatment at 14.5% and 7.3%, respectively, whereas the proportion of treated infants at or above a GA of 29 weeks was 0.06%. Similarly, the risk of sROP declined strongly with increasing GA. During the observation period of 10 years, the incidence of ROP treatment ranged between 0.8% and 2.0%. Incidences of sROP or ROP treatment did not increase over time. CONCLUSION: The incidence of ROP treatment in Switzerland is low and was stable over the analysed period. The low incidence of sROP in patients with a GA of 29 weeks or more leaves room for a redefinition of ROP screening criteria.

Diagnosis and Management of Necrotizing Enterocolitis: An International Survey of Neonatologists and Pediatric Surgeons.

BACKGROUND: Necrotizing enterocolitis (NEC) is a serious complication of prematurity. Currently, there is limited evidence to guide investigation and treatment strategies. OBJECTIVES: To evaluate the parameters used to diagnose or exclude NEC, and to identify differences between neonatologists and pediatric surgeons. METHODS: A scenario-based survey was sent to neonatologists and pediatric surgeons. RESULTS: 173 physicians from 26 countries completed the survey (55% neonatologists and 45% pediatric surgeons). Bloody stools, abdominal tenderness, low platelet counts, and increased lactate levels increased the likelihood of NEC for 82, 72, 56, and 45% of respondents, respectively. Intestinal pneumatosis, portal venous gas, and pneumoperitoneum on X-ray increased the likelihood of NEC for 99, 98, and 92% of respondents, respectively. Clinical examination and laboratory tests were insufficient to exclude NEC, but normal intestinal movements and normal gut wall thickness on ultrasonography decreased the likelihood of NEC for 38 and 33% of respondents, respectively. Neonatologists more frequently relied on increased gastric residuals and abdominal distension to diagnose NEC (p = 0.04 and p = 0.03, respectively), whereas pediatric surgeons more frequently reported that absence of bloody stools helped to exclude NEC (p = 0.04). In a deteriorating patient with suspected NEC, 39% of respondents would broaden the antibiotic spectrum, and 42% would recommend a laparotomy. CONCLUSION: Our results indicate a wide variation in the management of NEC, with significant differences between neonatologists and pediatric surgeons. A better appreciation of the relative significance and weighting that should be applied to the clinical features and investigations should reduce the variation in interpretation that appears to exist.

"Late" Withdrawal Syndrome after Carbamazepine In Utero Exposure in a CYP2C9 Slow Metabolizer Newborn.

We report a case of carbamazepine withdrawal syndrome following in utero exposure to carbamazepine related to a pharmacogenetic predisposition factor. The infant was born at 37 1/7 weeks' gestation by cesarean section to a mother treated for epilepsy with carbamazepine. One hour and thirty minutes after birth, the infant presented a respiratory distress with severe oxygen desaturation requiring intubation 5 h after birth. On the third day of life the infant developed clinical signs of a withdrawal syndrome which resolved progressively after 16 days and symptomatic treatment. The infant genotype analysis showed two low activity CYP2C9 allelic variants (∗2/∗3 heterozygote) predicting a CYP2C9 slow metabolizer phenotype which could explain reduced carbamazepine elimination and a late and long-lasting withdrawal symptoms observed 3 days after birth. The association of a withdrawal syndrome with carbamazepine exposure has not been previously reported and pharmacogenetic tests might therefore be useful in identifying patients at risk.

Accuracy of Transcutaneous Carbon Dioxide Measurement in Premature Infants.

Background. In premature infants, maintaining blood partial pressure of carbon dioxide (pCO2) value within a narrow range is important to avoid cerebral lesions. The aim of this study was to assess the accuracy of a noninvasive transcutaneous method (TcpCO2), compared to blood partial pressure of carbon dioxide (pCO2). Methods. Retrospective observational study in a tertiary neonatal intensive care unit. We analyzed the correlation between blood pCO2 and transcutaneous values and the accuracy between the trends of blood pCO2 and TcpCO2 in all consecutive premature infants born at <33 weeks' gestational age. Results. 248 infants were included (median gestational age: 29 + 5 weeks and median birth weight: 1250 g), providing 1365 pairs of TcpCO2 and blood pCO2 values. Pearson's R correlation between these values was 0.58. The mean bias was -0.93 kPa with a 95% confidence limit of agreement of -4.05 to +2.16 kPa. Correlation between the trends of TcpCO2 and blood pCO2 values was good in only 39.6%. Conclusions. In premature infants, TcpCO2 was poorly correlated to blood pCO2, with a wide limit of agreement. Furthermore, concordance between trends was equally low. We warn about clinical decision-making on TcpCO2 alone when used as continuous monitoring.

Thirteen-year mortality and morbidity in preterm infants in Switzerland.

OBJECTIVE: To report the population-based, gestational age (GA)-stratified mortality and morbidity for very preterm infants over 13 years in Switzerland. DESIGN: A prospective, observational study including 95% of Swiss preterm infants (GA <32 weeks) during three time periods: 2000-2004 (P1), 2005-2008 (P2) and 2009-2012 (P3). SETTING: The Swiss Neonatal Network, covering all level III neonatal intensive care units (NICUs) and affiliated paediatric hospitals. PATIENTS: 8899 live-born preterm infants with GA <32 weeks. MAIN OUTCOME MEASURES: Trends in GA-specific mortality (overall, delivery room and NICU), 'survival free of major complications' and major short-term morbidities: bronchopulmonary dysplasia (BPD, oxygen requirement at 36 weeks), grades 3 and 4 intraventricular haemorrhage (IVH 3-4), necrotising enterocolitis (NEC) and cystic periventricular leukomalacia (cPVL). RESULTS: Survival rate was 84.4%; 5.7% died in the delivery room and 9.9% died in the NICU. Neonatal mortality was 8.6% and post-neonatal mortality in NICU admissions was 1.3%. Reductions were observed in overall mortality from 18.4% (95% CI 17.0% to 19.8%) in P1 to 13.8% (13% to 15%) in P3, NICU mortality from 12.6% (11.4% to 13.8%) to 8.2% (7.2% to 9.2%) and IVH 3-4 from 7.8% (6.8% to 8.7%) to 5.8% (4.9% to 6.6%). There was no change in the incidence of cPVL and NEC. The BPD (oxygen requirement at 36 weeks) incidence displayed a U-shaped distribution across the three time periods. Overall, 71.0% (70.0% to 72.0%) had 'survival free of major complications' at the time of hospital discharge, and this significantly improved from 66.7% (65.0% to 68.4%) to 72.4% (70.8% to 74.0%) between P1 and P3. CONCLUSIONS: Survival rates of very preterm infants increased with decreasing delivery room and neonatal mortalities, mostly in extremely preterm infants. The incidence of IVH 3-4 decreased, whereas the incidences of cPVL, NEC and BPD (oxygen requirement at 36 weeks) remained largely unchanged from 2000 to 2012 in Switzerland.

Moderate and extended neonatal resuscitations occur in one in 10 births and require specialist cover 24 hours a day.

AIM: Neonatal resuscitation requires minimal equipment, but the immediate availability of expert staff accounts for the largest proportion of the costs. Despite this, staff requirements and timetables are currently planned without comprehensive epidemiologic data. The aim of this study was to evaluate the staffing required for neonatal resuscitations in the delivery room. METHODS: We measured attendance for each specific role in a tertiary university-affiliated hospital and for four possible intervention levels: preparation time, basic paediatric care, moderate resuscitation and extended resuscitation. RESULTS: Between 2005 and 2012, resuscitation staff attended 11 561 of the 32 799 births: 27.2% for preparation time, 17.7% for basic paediatric care, 6.4% for moderate resuscitation and 3.5% for extended resuscitation. Moderate and extended resuscitations occurred in roughly 10% of births and evenly during 24-h periods. Basic paediatric care levels were higher during weekday mornings, and extended resuscitations were uniformly distributed. However, there was a drop in all types of interventions around 7 a.m. to 8 a.m., when staff were changing shifts. CONCLUSION: Moderate and extended resuscitations occurred evenly over 24 h in roughly 10% of births, stressing the importance of having a highly competent neonatal team constantly available. All activities associated with resuscitation were lower during morning shift changes.
