[Newborn resuscitation and support of transition of infants at birth].

ABSTRACT: The European Resuscitation Council has produced these newborn life support guidelines, which are based on the International Liaison Committee on Resuscitation (ILCOR) 2020 Consensus on Science and Treatment Recommendations (CoSTR) for Neonatal Life Support. The guidelines cover the management of the term and preterm infant. The topics covered include an algorithm to aid a logical approach to resuscitation of the newborn, factors before delivery, training and education, thermal control, management of the umbilical cord after birth, initial assessment and categorisation of the newborn infant, airway and breathing and circulation support, communication with parents, considerations when withholding and discontinuing support.

Project description:ObjectiveDeciding whether initiating or withholding resuscitation at birth for extremely preterm infants (EPIs) can be difficult due to uncertainty on outcomes. Clinical uncertainty generates ethical uncertainty. Thus, physicians' attitudes and perspectives on resuscitation of EPIs might influence resuscitation decisions. We aimed at understanding how neonatologists make clinical-ethical decisions for EPI resuscitation and how they perceive these decisions.MethodsWe performed a qualitative study using a constructivist account of grounded theory. Face-to-face, semi-structured in-depth interviews with neonatologists comprised data collection. For data analysis, we used the Qualitative Analysis Guide of Leuven.ResultsWe interviewed 20 neonatologists working in 10 hospitals in Belgium. Participants' decision-making can be described as consensus-based, gestational age-based, contextualized, progressive, and shared. All participants agreed on the importance of using the consensus expressed in guidelines as a guidance for the decision-making, i.e., consensus-based. Consequently, all 20 participants use GA thresholds indicated in the guidelines, i.e., GA-based. However, they use these thresholds differently in their decisions. Few participants rigidly follow established thresholds. The vast majority reported using additional contextual factors as birthweight or parents' wishes in the decision-making, rather than only the EPIs' GA, i.e., contextualized. All participants agreed on the importance of involving the parents in the decision-making, i.e., shared, and indeed parents' wishes were among the most valued factors considered in the decision-making. However, the extent to which parents were involved in the decision-making depended on the infant's GA. Participants described a gray zone in which parents' were viewed as the main decision-makers due to the high clinical uncertainty. This mean that participants tend to follow parents' request even when they disagree with it. Outside the gray zone, physicians were viewed as the main decision-makers. This mean that, although parents' wishes were still considered, counseling was more directive and the final decision was made by the physician.ConclusionAlthough an EPI's GA remains the main factor guiding neonatologists' resuscitation decisions, other factors are seriously considered in the decision-making process. All neonatologist participants agreed on the importance of involving parents in the decision-making. However, they involve parents differently depending on the EPI's GA.

Project description:BackgroundExperiments have shown improved cardiovascular stability in lambs if umbilical cord clamping is postponed until positive pressure ventilation is started. Studies on intact cord resuscitation on human term infants are sparse. The purpose of this study was to evaluate differences in clinical outcomes in non-breathing infants between groups, one where resuscitation is initiated with an intact umbilical cord (intervention group) and one group where cord clamping occurred prior to resuscitation (control group).MethodsRandomized controlled trial, inclusion period April to August 2016 performed at a tertiary hospital in Kathmandu, Nepal. Late preterm and term infants born vaginally, non-breathing and in need of resuscitation according to the 'Helping Babies Breathe' algorithm were randomized to intact cord resuscitation or early cord clamping before resuscitation. Main outcome measures were saturation by pulse oximetry (SpO2), heart rate and Apgar at 1, 5 and 10 minutes after birth.ResultsAt 10 minutes after birth, SpO2 (SD) was significantly higher in the intact cord group compared to the early cord clamping group, 90.4 (8.1) vs 85.4 (2.7) %, P < .001). In the intact cord group, 57 (44%) had SpO2 < 90% after 10 minutes, compared to 93 (100%) in the early cord clamping group, P < 0.001. SpO2 was also significantly higher in the intervention (intact cord) group at one and five minutes after birth. Heart rate was lower in the intervention (intact cord) group at one and five minutes and slightly higher at ten minutes, all significant findings. Apgar score was significantly higher at one, five and ten minutes. At 5 minutes, 23 (17%) had Apgar score < 7 in the intervention (intact cord) group compared to 26 (27%) in the early cord clamping group, P < .07. Newborn infants in the intervention (intact cord) group started to breathe and establish regular breathing earlier than in the early cord clamping group.ConclusionsThis study provides new and important information on the effects of resuscitation with an intact umbilical cord. The findings of improved SpO2 and higher Apgar score, and the absence of negative consequences encourages further studies with longer follow-up.Trial registrationClinicaltrials.gov NCT02727517, 2016/4/4.

Project description:Background: Evidence for recommendations on the use of volume expansion during cardiopulmonary resuscitation in newborn infants is limited. Objectives: To develop a newborn piglet model with asphyxia, hemorrhage, and cardiac arrest to test different volume resuscitation on return of spontaneous circulation (ROSC). We hypothesized that immediate red cell transfusion reduces time to ROSC as compared to the use of an isotonic crystalloid fluid. Methods: Forty-four anaesthetized and intubated newborn piglets [age 32 h (12-44 h), weight 1,220 g (1,060-1,495g), Median (IQR)] were exposed to hypoxia and blood loss until asystole occurred. At this point they were randomized into two groups: (1) Crystalloid group: receiving isotonic sodium chloride (n = 22). (2) Early transfusion group: receiving blood transfusion (n = 22). In all other ways the piglets were resuscitated according to ILCOR 2015 guidelines [including respiratory support, chest compressions (CC) and epinephrine use]. One hour after ROSC piglets from the crystalloid group were randomized in two sub-groups: late blood transfusion and infusion of isotonic sodium chloride to investigate the effects of a late transfusion on hemodynamic parameters. Results: All animals achieved ROSC. Comparing the crystalloid to early blood transfusion group blood loss was 30.7 ml/kg (22.3-39.6 ml/kg) vs. 34.6 ml/kg (25.2-44.7 ml/kg), Median (IQR). Eleven subjects did not receive volume expansion as ROSC occurred rapidly. Thirty-three animals received volume expansion (16 vs. 17 in the crystalloid vs. early transfusion group). 14.1% vs. 10.5% of previously extracted blood volume in the crystalloid vs. early transfusion group was infused before ROSC. There was no significant difference in time to ROSC between groups [crystalloid group: 164 s (129-198 s), early transfusion group: 163 s (162-199 s), Median (IQR)] with no difference in epinephrine use. Conclusions: Early blood transfusion compared to crystalloid did not reduce time to ROSC, although our model included only a moderate degree of hemorrhage and ROSC occurred early in 11 subjects before any volume resuscitation occurred.

Project description:BackgroundLow birth weight (LBW) infants are at increased risk of morbidity and mortality. Identification of LBW may not occur in settings where access to reliable scales is limited. Mid-upper arm circumference (MUAC) may be an accessible, low-cost measure to identify LBW and vulnerable infants.ObjectivesWe explored the validity of newborn MUAC in identifying LBW and vulnerable newborns in rural Sierra Leone.MethodsThis study was a secondary analysis of infant data from a randomized controlled clinical trial of supplementary food and anti-infective therapies compared with standard care for undernourished pregnant women. Data for singleton liveborn infants with birth measurement and 6-mo survival data were included in this analysis. The primary outcome was validity of MUAC in identifying low-birth weight (LBW) neonates. Secondary outcomes included validity of MUAC and head circumference (HC) in identifying weight-for-length z-score (WLZ) <-2, length-for-age z-score (LAZ) <-2, neonatal mortality, and mortality within the first 6 mo of life.ResultsThe study population included 1167 infants, 229 (19.6%) with LBW. Birth MUAC (r = 0.817) and HC (r = 0.752) were highly correlated with birth weight. MUAC (AUC: 0.905; 95% CI: 0.884, 0.925) performed superiorly to HC (AUC: 0.88; 95% CI: 0.856, 0.904) in identifying LBW. The MUAC for identifying LBW was 9.6 cm (sensitivity: 0.86; specificity: 0.78). Neither MUAC nor HC reliably identified newborns with WLZ <-2 or LAZ <-2. MUAC ≤9.0 cm was the ideal cutoff for neonatal mortality (sensitivity: 53.3%; specificity: 89.7%; HR: 9.57; 95% CI: 1.86, 49.30). Birth anthropometrics did not reliably identify infants at risk of death in the first 6 mo of life.ConclusionsMUAC was used successfully to identify LBW infants and infants at risk of neonatal mortality in Sierra Leone. Further evidence is needed to support increased use of newborn MUAC measurement to identify LBW infants and infants at risk of neonatal mortality in community settings where scales are not available. Primary trial was registered at clinicaltrials.gov as NCT03079388.Lay summaryMid-upper arm circumference (MUAC) can be used to identify infants with low birth weight and infants at risk for neonatal mortality, with an MUAC ≤9.0 cm indicating the highest risk.
