RESUMO
The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Initial discharge from a neonatal intensive care unit (NICU) to home is a crucial milestone that impacts preterm infants, their families, and NICUs. Standardized discharge programs individualized for family needs can ensure a safe transfer of care to parents, decrease the length of stay and hospital costs, and improve parents' satisfaction. To assess the degree of variability in the current discharge criteria of preterm infants less than 34 weeks' gestation among Canadian NICUs, explore different institution-specific guidelines and degree of adherence to the Canadian Paediatric Society (CPS) guidelines. A clinical representative of each of the 117 level 2-4 Canadian NICUs was contacted via email to participate in an anonymous survey link regarding the discharge criteria of preterm infants. Responders from ninety-eight NICUs (84%), representing all Canadian provinces, completed the survey. Most were nurse practitioners (43%) and neonatologists (31%) with > 5 years of experience (87%). Level 3 and 4 NICUs represented 63% of responses. Units varied widely in many discharge criteria and in their adherence to CPS guidelines. Most of the units (81%) lack written discharge guidelines; 60% do not have a dedicated discharge coordinator, and 45% do not have a post-discharge clinic. Only 25% routinely teach parents CPR and only half of the surveyed units provide parental support programs. Conclusion: There is a significant heterogeneity in discharge practices of preterm infants among Canadian NICUs. This survey provides a basis for benchmarking and knowledge sharing. What is Known: ⢠Discharging preterm infants from the NICU impacts preterm infants, their families, and NICUs. ⢠All efforts should ensure a safe transfer of care to parents, decrease the length of stay, better utilize resources, and improve parents' satisfaction. What is New: ⢠The discharge criteria of preterm infants vary widely among NICUs. ⢠This survey provides benchmark information and exposes the need to better standardize discharge practices and the subsequent support for infants and parents.

BACKGROUND: Delayed cord clamping and umbilical cord milking provide placental transfusion to vigorous newborns. Delayed cord clamping in nonvigorous newborns may not be provided owing to a perceived need for immediate resuscitation. Umbilical cord milking is an alternative, as it can be performed more quickly than delayed cord clamping and may confer similar benefits. OBJECTIVE: We hypothesized that umbilical cord milking would reduce admission to the neonatal intensive care unit compared with early cord clamping in nonvigorous newborns born between 35 and 42 weeks' gestation. STUDY DESIGN: This was a pragmatic cluster-randomized crossover trial of infants born at 35 to 42 weeks' gestation in 10 medical centers in 3 countries between January 2019 and May 2021. The centers were randomized to umbilical cord milking or early cord clamping for approximately 1 year and then crossed over for an additional year or until the required number of consented subjects was reached. Waiver of consent as obtained in all centers to implement the intervention. Infants were eligible if nonvigorous at birth (poor tone, pale color, or lack of breathing in the first 15 seconds after birth) and were assigned to umbilical cord milking or early cord clamping according to their birth hospital randomization assignment. The baseline characteristics and outcomes were collected following deferred informed consent. The primary outcome was admission to the neonatal intensive care unit for predefined criteria. The main safety outcome was hypoxic-ischemic encephalopathy. Data were analyzed by the intention-to-treat concept. RESULTS: Among 16,234 screened newborns, 1780 were eligible (905 umbilical cord milking, 875 early cord clamping), and 1730 had primary outcome data for analysis (97% of eligible; 872 umbilical cord milking, 858 early cord clamping) either via informed consent (606 umbilical cord milking, 601 early cord clamping) or waiver of informed consent (266 umbilical cord milking, 257 early cord clamping). The difference in the frequency of neonatal intensive care unit admission using predefined criteria between the umbilical cord milking (23%) and early cord clamping (28%) groups did not reach statistical significance (modeled odds ratio, 0.69; 95% confidence interval, 0.41-1.14). Umbilical cord milking was associated with predefined secondary outcomes, including higher hemoglobin (modeled mean difference between umbilical cord milking and early cord clamping groups 0.68 g/dL, 95% confidence interval, 0.31-1.05), lower odds of abnormal 1-minute Apgar scores (Apgar ≤3, 30% vs 34%, crude odds ratio, 0.72; 95% confidence interval, 0.56-0.92); cardiorespiratory support at delivery (61% vs 71%, modeled odds ratio, 0.57; 95% confidence interval, 0.33-0.99), and therapeutic hypothermia (3% vs 4%, crude odds ratio, 0.57; 95% confidence interval, 0.33-0.99). Moderate-to-severe hypoxic-ischemic encephalopathy was significantly less common with umbilical cord milking (1% vs 3%, crude odds ratio, 0.48; 95% confidence interval, 0.24-0.96). No significant differences were observed for normal saline bolus, phototherapy, abnormal 5-minute Apgar scores (Apgar ≤6, 15.7% vs 18.8%, crude odds ratio, 0.81; 95% confidence interval, 0.62-1.06), or a serious adverse event composite of death before discharge. CONCLUSION: Among nonvigorous infants born at 35 to 42 weeks' gestation, umbilical cord milking did not reduce neonatal intensive care unit admission for predefined criteria. However, infants in the umbilical cord milking arm had higher hemoglobin, received less delivery room cardiorespiratory support, had a lower incidence of moderate-to-severe hypoxic-ischemic encephalopathy, and received less therapeutic hypothermia. These data may provide the first randomized controlled trial evidence that umbilical cord milking in nonvigorous infants is feasible, safe and, superior to early cord clamping.

BACKGROUND: Infants with restricted growth for age are frequently exposed to insufficient placental circulation and are more likely to develop postnatal complications. Delayed cord clamping at birth for these infants requires further exploration. OBJECTIVE: This study aimed to compare the short-term neonatal outcomes of delayed cord clamping with that of early cord clamping in small for gestational age preterm infants and to explore whether the effects of delayed cord clamping in small for gestational age preterm infants are different from that in non-small for gestational age preterm infants. STUDY DESIGN: We conducted a national retrospective cohort study, including infants born at <33 weeks' gestation and admitted to the Canadian Neonatal Network units between January 2015 and December 2017. Small for gestational age infants (birthweight of <10th percentile for gestational age and sex) who received delayed cord clamping ≥30 seconds were compared with those who received early cord clamping. In addition, non-small for gestational age infants who received delayed cord clamping were compared with those who received early cord clamping. The main study outcomes included composite outcome of mortality or major morbidity, neonatal morbidity rate, mortality rate, peak serum bilirubin, and number of blood transfusions. Multivariable logistic and linear regression models with a generalized estimation equation approach were used to account for the clustering of infants within centers. RESULTS: Overall, 9722 infants met the inclusion criteria. Of those infants, 1027 (10.6%) were small for gestational age. The median (interquartile range) gestational age was 31 weeks (range, 28-32 weeks). After adjusting for potential confounders, delayed cord clamping in small for gestational age infants was associated with a reduction in the composite outcome of mortality or major morbidity (adjusted odds ratio, 0.60; 95% confidence interval, 0.42-0.86) compared with early cord clamping. There was no difference between the 2 groups in peak serum bilirubin. Many associated benefits of delayed cord clamping in small for gestational age infants were similar to those in non-small for gestational age infants. CONCLUSION: Delayed cord clamping in small for gestational age preterm infants was associated with decreased odds of mortality or major morbidity. Many of the benefits of delayed cord clamping in the small for gestational age preterm infants were similar to those identified in the non-small for gestational age preterm infants.

Umbilical cord milking improves postnatal adaptation and short-term outcomes of very preterm infants compared to early cord clamping. Little is known about the impact of umbilical cord milking on long-term neurodevelopmental outcomes. The objective of this study is to compare the effects of intact umbilical cord milking (UCM) vs. early cord clamping (ECC) at birth on neurodevelopmental outcomes at 36 months' corrected age. Preterm infants < 31 weeks' gestation who were randomized at birth to receive three time milking of their attached cord or ECC (< 10 s) were evaluated at 36 months' corrected age. Neurodevelopmental outcomes were assessed by blinded examiners using Bayley Scales of Infant and Toddler Development (version III). Analysis was by intention to treat. Out of the 73 infants included in the original trial, 2 died and 65 (92%) infants were evaluated at 36 months' corrected age. Patient characteristics and short-term outcomes were similar in both study groups. There were no significant differences in the median cognitive, motor or language scores or in the rates of cerebral palsy, developmental impairment, deafness, or blindness between study groups. CONCLUSION: Neurodevelopmental outcomes at 36 months' corrected age of very preterm infants who received UCM were not shown to be significantly different from those who received ECC at birth. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01487187 What is Known: ⢠Compared to early cord clamping, umbilical cord milking improves postnatal adaptation and short-term outcomes of very preterm infants compared to early cord clamping. ⢠Little is known about the impact of umbilical cord milking on neurodevelopmental outcomes. WHAT IS NEW: ⢠Neurodevelopmental outcomes at 3 years of age were not significantly different in very preterm infants who received cord milking vs. those who received early cord clamping at birth.

BACKGROUND: The preferred timing of umbilical-cord clamping in preterm infants is unclear. METHODS: We randomly assigned fetuses from women who were expected to deliver before 30 weeks of gestation to either immediate clamping of the umbilical cord (≤10 seconds after delivery) or delayed clamping (≥60 seconds after delivery). The primary composite outcome was death or major morbidity (defined as severe brain injury on postnatal ultrasonography, severe retinopathy of prematurity, necrotizing enterocolitis, or late-onset sepsis) by 36 weeks of postmenstrual age. Analyses were performed on an intention-to-treat basis, accounting for multiple births. RESULTS: Of 1634 fetuses that underwent randomization, 1566 were born alive before 30 weeks of gestation; of these, 782 were assigned to immediate cord clamping and 784 to delayed cord clamping. The median time between delivery and cord clamping was 5 seconds and 60 seconds in the respective groups. Complete data on the primary outcome were available for 1497 infants (95.6%). There was no significant difference in the incidence of the primary outcome between infants assigned to delayed clamping (37.0%) and those assigned to immediate clamping (37.2%) (relative risk, 1.00; 95% confidence interval, 0.88 to 1.13; P=0.96). The mortality was 6.4% in the delayed-clamping group and 9.0% in the immediate-clamping group (P=0.03 in unadjusted analyses; P=0.39 after post hoc adjustment for multiple secondary outcomes). There were no significant differences between the two groups in the incidences of chronic lung disease or other major morbidities. CONCLUSIONS: Among preterm infants, delayed cord clamping did not result in a lower incidence of the combined outcome of death or major morbidity at 36 weeks of gestation than immediate cord clamping.

OBJECTIVE: To evaluate the rates of practice, and the associations between different cord management strategies at birth (delayed cord clamping [DCC], umbilical cord milking [UCM], and early cord clamping [ECC]) and mortality or major morbidity, rates of blood transfusion, and peak serum bilirubin in a large national cohort of very preterm infants. STUDY DESIGN: We retrospectively studied preterm infants <33 weeks of gestation admitted to the Canadian Neonatal Network between January 2015 and December 2017. Patients who received ECC (<30 seconds), UCM, or DCC (≥30 seconds) were compared. Multiple generalized linear/quantile logistic regression models were used. RESULTS: Of 12 749 admitted infants, 9729 were included; 4916 (50.5%) received ECC, 394 (4.1%) UCM, and 4419 (45.4%) DCC. After adjustment for potential confounders identified between groups in univariate analyses, the odds of mortality or major morbidity were higher in the ECC group when compared with UCM group (aOR, 1.18; 95% CI, 1.03-1.35). Mortality and intraventricular hemorrhage were associated with ECC as compared with DCC (aOR, 1.6 [95% CI, 1.22-2.1] and aOR, 1.29 [95% CI, 1.19-1.41], respectively). The odds of severe intraventricular hemorrhage were higher with UCM compared with DCC (aOR, 1.38; 95% CI, 1.05-1.81). Rates of blood transfusion were higher with ECC compared with UCM and DCC (aOR, 1.67 [95% CI, 1.31-2.14] and aOR, 1.68 [95% CI, 1.35-2.09], respectively), although peak serum bilirubin levels were not significantly different. CONCLUSIONS: Both DCC and UCM were associated with better short-term outcomes than ECC; however, the odds of severe intraventricular hemorrhage were higher with UCM compared with DCC.

OBJECTIVE: The goal of this study was to obtain population-based data on the incidence, clinical presentation, management, imaging features, and long-term outcomes of patients with all types of neonatal stroke (NS). METHODS: Full-term neonates with NS born between January 2007 and December 2013 were identified through the Nova Scotia Provincial Perinatal Follow-up Program Database. Perinatal data and neonatal course were reviewed. Neurodevelopmental outcomes were assessed at 18 and 36 months of age using standardized testing. RESULTS: Twenty-nine neonates with NS were identified during the study period, giving an incidence of 47 per 100,000 live births in Nova Scotia. Arterial ischemic stroke was the most common stroke type (76%), followed by neonatal hemorrhagic stroke (17%), then cerebral sinovenous thrombosis (7%). The majority of neonates presented with seizures (86%) on the first day of life (76%). At 36 months of age, 23 (79%) of the children had a normal outcome, while 3 (10%) were diagnosed with cerebral palsy (2 with neonatal arterial stroke and one with neonatal hemorrhagic stroke) and 3 (10%) had recurrent seizures (1 patient from each stroke subtype group). CONCLUSION: The incidence of NS in Nova Scotia is higher than what has been reported internationally in the literature. However, the neurodevelopmental outcomes at 3 years of age are better. Further studies are required to better understand the reasons for these findings.
RESUMO
OBJECTIVE: This article assesses the degree of variability in the current practice of skin antiseptics used in Canadian neonatal intensive care units (NICUs) and different experiences related to each antiseptic used. METHODS: An anonymous survey was distributed to a clinical representative of each of the 124 Canadian level II and level III NICUs. RESULTS: One hundred and two respondents (82.2%), representing all Canadian provinces, completed the survey. Chlorhexidine gluconate with/without alcohol was the antiseptic most used (96%) and the antiseptic with the highest reported adverse effects (68% reported skin burns/breakdown). Other antiseptics used include povidone-iodine (35%) and isopropyl alcohol (22%). Specific guidelines for antiseptic use were available in only 50% of the units with many NICUs lacking gestational and/or chronological age restrictions. Only 23% of responders believed that there was awareness among health care providers of the adverse effects of antiseptics used. Less than half (43%) were completely satisfied with the antiseptics used in their units. CONCLUSION: Chlorhexidine gluconate is the most commonly used antiseptic in Canadian NICUs. The high number of associated adverse effects and the lack of guidelines regulating antiseptic use are of concern. Large clinical trials are urgently needed to guide practice and improve the safety of antiseptics.

OBJECTIVE: To evaluate the significance and predictive value of each of the Neonatal Resuscitation Program (NRP)-listed ante- and intrapartum risk factors for the need of neonatal intubation at birth. STUDY DESIGN: In this population-based study, perinatal data of all infants born at ≥ 35 weeks gestation in the province of Nova Scotia between 1994 and 2014, were identified and reviewed from the Nova Scotia Atlee Database. The frequency of occurrence of risk factors, incidence of neonatal intubation at birth, and its relationship with the different NRP-listed risk factors, were examined. Variables that were significant (P < .05) in univariate analyses were entered into the regression model. RESULTS: During the 20-year study period, 176,365 infants ≥ 35 weeks gestation were born. In presence of any of the listed risk factors, 0.3% of infants received intubation at birth compared with 0.08% in absence of any risk factor (P < .001). On logistic regression analysis, only 16 of the NRP-listed risk factors had a significant relationship with intubation at birth (P < .001). Delivery in a tertiary care center did not have an impact. CONCLUSIONS: The presence of an intubation-skilled person at birth may not be indicated in all the NRP-listed ante- and intrapartum risk factors. Stratification of the relative significance of different risk factors may be of importance for the less-resourced health care units providing maternal and newborn care.

OBJECTIVES: To evaluate the frequency of central venous catheter (CVC)-related thrombi detected by routine surveillance ultrasound, and to assess whether positive findings had an impact on management or outcomes. STUDY DESIGN: All neonates in a tertiary neonatal intensive care unit who had a CVC inserted for >14 days underwent routine surveillance ultrasound biweekly between January 2003 and December 2009. Data were reviewed retrospectively. RESULTS: Although all neonates were asymptomatic at time of surveillance ultrasound, 645 of the total 1333 CVCs inserted in 1012 neonates underwent surveillance ultrasound, and thrombi were detected in 69 (10.7%). The CVCs with thrombi were more likely to be removed for nonelective reasons compared with CVCs without thrombi (59% vs 38%; P = .001; OR, 2.4, 95% CI 1.4-3.9). A total of 955 surveillance ultrasounds were performed to detect and monitor 69 CVCs with thrombi. The majority of thrombi were nonocclusive and nonprogressive. A change in management occurred in 8 cases of CVC-related thrombi (12%), or 1% of all screened cases. An average of 14 ultrasounds were required to detect and monitor 1 CVC with thrombus, at a cost of $951 per CVC with thrombus and $8106 per case of CVC-related thrombi with a change in treatment. CONCLUSION: Asymptomatic thrombi were detected in a significant proportion of CVCs by routine surveillance ultrasound. There were significant costs, but infrequent changes to patient management.

INTRODUCTION: Optimal oxygen saturation targets remain unknown for extremely preterm infants. METHODS: Cohort analysis of eligible preterm infants born <29 weeks' gestation admitted between 2011 and 2018 to centers submitting data to the Canadian Neonatal Network (CNN) database. Site questionnaires to determine saturation targets, alarm settings, and date of change, allowed assignation of centers to intermediate (88-93%) or high (90-95%) saturation targets. A 6-month washout period was applied to sites which switched targets during the study period. Our primary outcome was survival free of major morbidity. Secondary outcomes were death, necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), treated retinopathy of prematurity, and evidence of brain injury during admission. Generalized estimating equations were applied to compensate for demographic differences and site practices. RESULTS: There were 2,739 infants in the high (mean gestational age [GA] 26 ± 1.6 weeks) and 6,813 infants in the intermediate (mean GA 26.2 ± 1.6 weeks) saturation target group. Survival without morbidity was higher in the intermediate target group (adjusted odds ratio [aOR] 1.59; 95% CI: 1.04, 2.45). There was no difference in mortality between groups (aOR 0.81; 95% CI: 0.59, 1.11), in NEC, treated retinopathy, or brain injury. On subgroup analysis, restricting data to sites which switched targets during the study, intermediate saturation targets were associated with lower rates of BPD (aOR 0.45; 95% CI: 0.28, 0.72). CONCLUSION: For neonates <29 weeks' gestation, intermediate saturation target was associated with higher odds of survival without major morbidity compared to higher oxygen saturation target.
RESUMO
OBJECTIVES: To determine parental perspectives in a trial with waived consent. STUDY DESIGN: Anonymous survey of birth parents with term infants who were randomized using a waiver of consent, administered after infant discharge. RESULTS: 121 (11%) survey responses were collected. Of the 121 responding parents 111 (92%) reported that this form of consent was acceptable and 116 (96%) reported feeling comfortable having another child participate in a similar study. 110 (91%) respondents reported that they both understood the information provided in the consent process and had enough time to consider participation. Four percent had a negative opinion on the study's effect on their child's health. CONCLUSIONS: Most responding parents reported both acceptability of this study design in the neonatal period and that the study had a positive effect on their child's health. Future work should investigate additional ways to involve parents and elicit feedback on varied methods of pediatric consent.

BACKGROUND: Immediately after birth, the oxygen saturation is between 30 and 50%, which then increases to 85-95% within the first 10 min. Over the last 10 years, recommendations regarding the ideal level of the initial fraction of inspired oxygen (FiO2) for resuscitation in preterm infants have changed from 1.0, to room air to low levels of oxygen (< 0.3), up to moderate concentrations (0.3-0.65). This leaves clinicians in a challenging position, and a large multi-center international trial of sufficient sample size that is powered to look at safety outcomes such as mortality and adverse neurodevelopmental outcomes is required to provide the necessary evidence to guide clinical practice with confidence. METHODS: An international cluster, cross-over randomized trial of initial FiO2 of 0.3 or 0.6 during neonatal resuscitation in preterm infants at birth to increase survival free of major neurodevelopmental outcomes at 18 and 24 months corrected age will be conducted. Preterm infants born between 230/7 and 286/7 weeks' gestation will be eligible. Each participating hospital will be randomized to either an initial FiO2 concentration of either 0.3 or 0.6 to recruit for up to 12 months' and then crossed over to the other concentration for up to 12 months. The intervention will be initial FiO2 of 0.6, and the comparator will be initial FiO2 of 0.3 during respiratory support in the delivery room. The sample size will be 1200 preterm infants. This will yield 80% power, assuming a type 1 error of 5% to detect a 25% reduction in relative risk of the primary outcome from 35 to 26.5%. The primary outcome will be a composite of all-cause mortality or the presence of a major neurodevelopmental outcome between 18 and 24 months corrected age. Secondary outcomes will include the components of the primary outcome (death, cerebral palsy, major developmental delay involving cognition, speech, visual, or hearing impairment) in addition to neonatal morbidities (severe brain injury, bronchopulmonary dysplasia; and severe retinopathy of prematurity). DISCUSSION: The use of supplementary oxygen may be crucial but also potentially detrimental to preterm infants at birth. The HiLo trial is powered for the primary outcome and will address gaps in the evidence due to its pragmatic and inclusive design, targeting all extremely preterm infants. Should 60% initial oxygen concertation increase survival free of major neurodevelopmental outcomes at 18-24 months corrected age, without severe adverse effects, this readily available intervention could be introduced immediately into clinical practice.

INTRODUCTION: Patent ductus arteriosus (PDA) is the most common cardiovascular problem that develops in extremely preterm infants and is associated with poor clinical outcomes. Uncertainty exists on whether early pharmacotherapeutic treatment of a clinically symptomatic and echocardiography-confirmed haemodynamically significant PDA in extremely preterm infants improves outcomes. Given the wide variation in the approach to PDA treatment in this gestational age (GA) group, a randomised trial design is essential to address the question. Before embarking on a large RCT in this vulnerable population, it is important to establish the feasibility of such a trial. METHODS AND ANALYSIS: Design: a multi-centre, open-labelled, parallel-designed pilot randomised controlled trial. Participants: preterm infants born <26 weeks of gestation with a PDA diagnosed within 72 hours after birth. Intervention (selective early medical treatment (SMART) strategy): selective early pharmacological treatment of a moderate-severe PDA shunt (identified based on pre-defined clinical signs and routine screening echocardiography) within the first 72 postnatal hours with provision for repeat treatment if moderate-severe shunt persists. Comparison (early conservative management strategy): no treatment of PDA in the first postnatal week. Primary outcomes: (1) proportion of eligible infants recruited during the study period; (2) proportion of randomised infants treated outside of protocol-mandated therapy. Sites and sample size: the study is being conducted in seven neonatal intensive care units across Canada and the USA with a target of 100 randomised infants. Analysis: the primary feasibility outcomes will be expressed as proportions. A pre-planned Bayesian analysis will be conducted for secondary clinical outcomes such as mortality, severe intraventricular haemorrhage, procedural PDA closure and chronic lung disease to aid stakeholders including parent representatives decide on the appropriateness of enrolling this vulnerable population in a larger trial if the feasibility of recruitment in the pilot trial is established. ETHICS AND DISSEMINATION: The study has been approved by the IWK Research Ethics Board (#1027298) and six additional participating sites. On the completion of the study, results will be presented at national and international meetings, published in peer-reviewed journals and incorporated into existing systematic reviews. TRIAL REGISTRATION NUMBER: NCT05011149 (WHO Trial Registration Data Set in Appendix A). PROTOCOL VERSION: Ver 7.2 (dated July 19, 2023).

Importance: Compared with early cord clamping (ECC), umbilical cord milking (UCM) reduces delivery room cardiorespiratory support, hypoxic-ischemic encephalopathy, and therapeutic hypothermia in nonvigorous near-term and full-term infants. However, UCM postdischarge outcomes are not known. Objective: To determine the 2-year outcomes of children randomized to UCM or ECC at birth in the Milking in Nonvigorous Infants (MINVI) trial. Design, Setting, and Participants: A secondary analysis to evaluate longer-term outcomes of a cluster-randomized crossover trial was conducted from January 9, 2021, to September 25, 2023. The primary trial took place in 10 medical centers in the US, Canada, and Poland from January 5, 2019, to June 1, 2021, and hypothesized that UCM would reduce admission to the neonatal intensive care unit compared with ECC; follow-up concluded September 26, 2023. The population included near-term and full-term infants aged 35 to 42 weeks' gestation at birth who were nonvigorous; families provided consent to complete developmental screening questionnaires through age 2 years. Intervention: UCM and ECC. Main Outcomes and Measures: Ages and Stages Questionnaire, 3rd Edition (ASQ-3) and Modified Checklist for Autism in Toddlers, Revised/Follow-Up (M-CHAT-R/F) questionnaires at ages 22 to 26 months. Intention-to-treat analysis and per-protocol analyses were used. Results: Among 1730 newborns from the primary trial, long-term outcomes were evaluated in 971 children (81%) who had ASQ-3 scores available at 2 years or died before age 2 years and 927 children (77%) who had M-CHAT-R/F scores or died before age 2 years. Maternal and neonatal characteristics by treatment group were similar, with median birth gestational age of 39 (IQR, 38-40) weeks in both groups; 224 infants (45%) in the UCM group and 201 (43%) in the ECC group were female. The median ASQ-3 total scores were similar (UCM: 255 [IQR, 225-280] vs ECC: 255 [IQR, 230-280]; P = .87), with no significant differences in the ASQ-3 subdomains. Medium- to high-risk M-CHAT-R/F scores were also similar (UCM, 9% [45 of 486] vs ECC, 8% [37 of 441]; P = .86). Conclusions and Relevance: In this secondary analysis of a randomized clinical trial among late near-term and full-term infants who were nonvigorous at birth, ASQ-3 scores at age 2 years were not significantly different between the UCM and ECC groups. Combined with previously reported important short-term benefits, this follow-up study suggests UCM is a feasible, no-cost intervention without longer-term neurodevelopmental risks of cord milking in nonvigorous near-term and term newborns.

The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Objectives: To determine parental perspectives in a trial with waived consent. Study Design: Biological parents of non-vigorous term infants randomized using a waiver of consent for a delivery room intervention completed an anonymous survey after discharge. Results: 121 survey responses were collected. Most responding parents reported that this form of consent was acceptable (92%) and that they would feel comfortable having another child participate in a similar study (96%). The majority (> 90%) also reported that the information provided after randomization was clear to understand future data collection procedures. Four percent had a negative opinion on the study's effect on their child's health. Conclusions: The majority of responding parents reported both acceptability of this study design in the neonatal period and that the study had a positive effect on their child's health. Future work should investigate additional ways to involve parents and elicit feedback on varied methods of pediatric consent.
