Abstract
PARTICIPANTS This article includes 7293 infants (14 586 eyes) screened for ROP across 5 centers in the United States (Austin Retina Associates, Austin, TX; Bascom Palmer Eye Institute, Miami, FL; Beaumont Eye Institute, Royal Oak, MI; Massachusetts Eye and Ear, Boston, MA; and Stanford Byers Eye Institute, Stanford, CA). PURPOSE To analyze the incidence and timing of treatment requiring retinopathy of prematurity (ROP) in extremely small premature infants. We hypothesize that the smaller the infant by gestational age and birthweight, the higher their likelihood of requiring treatment for ROP. DESIGN Premature infants screened for Retinopathy of Prematurity from 2002-2022 were divided into cohorts based on the following criteria based on gestational age (GA) and birth weight (BW). "Micropremature infants" are infants born between 24-26 weeks GA and between 600-799 g BW. "Nanopremature infants" are born ≤ 24 weeks GA and ≤ 600 g BW. METHODS Retrospective chart review. MAIN OUTCOME MEASURES The incidence and timing of treatment-requiring ROP. RESULTS We found that infants defined as nanopremature had a ∼63% chance of requiring treatment at an average postmenstrual age (PMA) of 36.6 weeks, whereas those defined as micropremature had a 30% chance of requiring treatment at an average PMA of 36.3 weeks. This significantly contrasts with the risk of all screened babies for ROP where the risk of requiring treatment was 8.5%. CONCLUSION Micropremature and nanopremature infants are significantly more likely to require treatment for ROP. With demographic data matched to all 5 major US regions spanning the last decade, these results have the potential to inform neonatologists, pediatricians, and ophthalmologists of an important shift in the landscape of prematurity in the United States.

Abstract
Oxygen (O2) is crucial for both the development and treatment of one of the most important consequences of prematurity: bronchopulmonary dysplasia (BPD). In fetal life, the hypoxic environment is important for alveolar development and maturation. After birth, O2 becomes a double-edged sword. While O2 is needed to prevent hypoxia, it also causes oxidative stress leading to a plethora of morbidities, including retinopathy and BPD. The advent of continuous O2 monitoring with pulse oximeters has allowed clinicians to recognize the narrow therapeutic margins of oxygenation for the preterm infant, but more knowledge is needed to understand what these ranges are at different stages of the preterm infant's life, including at birth, in the neonatal intensive care unit and after hospital discharge. Future research, especially in innovative technologies such as automated O2 control and remote oximetry, will improve the understanding and treatment of the O2 needs of infants with BPD.

Abstract
BACKGROUND International guidelines recommend delayed umbilical cord clamping (DCC) up to 1 min in preterm infants, unless the condition of the infant requires immediate resuscitation. However, clamping the cord prior to lung aeration may severely limit circulatory adaptation resulting in a reduction in cardiac output and hypoxia. Delaying cord clamping until lung aeration and ventilation have been established (physiological-based cord clamping, PBCC) allows for an adequately established pulmonary circulation and results in a more stable circulatory transition. The decline in cardiac output following time-based delayed cord clamping (TBCC) may thus be avoided. We hypothesise that PBCC, compared to TBCC, results in a more stable transition in very preterm infants, leading to improved clinical outcomes. The primary objective is to compare the effect of PBCC on intact survival with TBCC. METHODS The Aeriation, Breathing, Clamping 3 (ABC3) trial is a multicentre randomised controlled clinical trial. In the interventional PBCC group, the umbilical cord is clamped after the infant is stabilised, defined as reaching heart rate > 100 bpm and SpO2 > 85% while using supplemental oxygen < 40%. In the control TBCC group, cord clamping is time based at 30-60 s. The primary outcome is survival without major cerebral and/or intestinal injury. Preterm infants born before 30 weeks of gestation are included after prenatal parental informed consent. The required sample size is 660 infants. DISCUSSION The findings of this trial will provide evidence for future clinical guidelines on optimal cord clamping management in very preterm infants at birth.

Electrocardiogram for heart rate evaluation during preterm resuscitation at birth: a randomized trial. Pediatr Res 2022; 91:1445-1451. [PMID: 34645954 PMCID: PMC8513736 DOI: 10.1038/s41390-021-01731-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 08/18/2021] [Accepted: 08/24/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Although electrocardiogram (ECG) can detect heart rate (HR) faster compared to pulse oximetry, it remains unknown if routine use of ECG for delivery room (DR) resuscitation reduces the time to stabilization in preterm infants. METHODS Neonates <31 weeks' gestation were randomized to either an ECG-displayed or an ECG-blinded HR assessment in the DR. HR, oxygen saturation, resuscitation interventions, and clinical outcomes were compared. RESULTS During the study period, 51 neonates were enrolled. The mean gestational age in both groups was 28 ± 2 weeks. The time to stabilization, defined as the time from birth to achieve HR ≥100 b.p.m., as well as oxygen saturation within goal range, was not different between the ECG-displayed and the ECG-blinded groups [360 (269, 435) vs 345 (240, 475) s, p = 1.00]. There was also no difference in the time to HR ≥100 b.p.m. [100 (75, 228) vs 138 (88, 220) s, p = 0.40] or duration of positive pressure ventilation (PPV) [345 (120, 558) vs 196 (150, 273) s, p = 0.36]. Clinical outcomes were also similar between groups. CONCLUSIONS Although feasible and safe, the use of ECG in the DR during preterm resuscitation did not reduce time to stabilization. IMPACT Although feasible and apparently safe, routine use of the ECG in the DR did not decrease time to HR >100 b.p.m., time to stabilization, or use of resuscitation interventions such as PPV for preterm infants <31 weeks' gestational age. This article adds to the limited randomized controlled trial evidence regarding the impact of routine use of ECG during preterm resuscitation on DR clinical outcomes. Such evidence is important when considering recommendations for routine use of the ECG in the DR worldwide as such a recommendation comes with a significant cost burden.

Outcomes of delivery room resuscitation of bradycardic preterm infants: A retrospective cohort study of randomised trials of high vs low initial oxygen concentration and an individual patient data analysis. Resuscitation 2021; 167:209-217.

Abstract
OBJECTIVE To determine whether hospital mortality (primary outcome) is associated with duration of bradycardia without chest compressions during delivery room (DR) resuscitation in a retrospective cohort study of randomized controlled trials (RCTs) in preterm infants assigned low versus high initial oxygen concentration. METHODS Medline and EMBASE were searched from 01/01/1990 to 12/01/2020. RCTs of low vs high initial oxygen concentration which recorded serial heart rate (HR) and oxygen saturation (SpO2) during resuscitation of infants <32 weeks gestational age were eligible. Individual patient level data were requested from the authors. Newborns receiving chest compressions in the DR and those with no recorded HR in the first 2 min after birth were excluded. Prolonged bradycardia (PB) was defined as HR < 100 bpm for ≥2 min. Individual patient data analysis and pooled data analysis were conducted. RESULTS Data were collected from 720 infants in 8 RCTs. Neonates with PB had higher odds of hospital death before [OR 3.8 (95% CI 1.5, 9.3)] and after [OR 1.7 (1.2, 2.5)] adjusting for potential confounders. Bradycardia occurred in 58% infants, while 38% had PB. Infants with bradycardia were more premature and had lower birth weights. The incidence of bradycardia in infants resuscitated with low (≤30%) and high (≥60%) oxygen was similar. Neonates with both, PB and SpO2 < 80% at 5 min after birth had higher odds of hospital mortality. [OR 18.6 (4.3, 79.7)]. CONCLUSION In preterm infants who did not receive chest compressions in the DR, prolonged bradycardia is associated with hospital mortality.

Abstract
Background: Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China. Methods: The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD. Results: A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082–4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606–3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044–1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061–2.424), DRI (OR, 2.094; 95% CI, 1.328–3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679–4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777–6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996–0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379–0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160–0.467) were preventive factors for BPD (all P < 0.05). Conclusion: Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

Abstract
OBJECTIVE To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation. METHODS A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (n=1 184), tracheal intubation (n=166), and extensive cardiopulmonary resuscitation (ECPR; n=116). The three groups were compared in terms of general information and clinical outcomes. RESULTS Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly lower rates of cesarean section and use of antenatal corticosteroid (P < 0.05). As the intensity of resuscitation increased, the Apgar scores at 1 minute and 5 minutes gradually decreased (P < 0.05), and the proportion of infants with Apgar scores of 0 to 3 at 1 minute and 5 minutes gradually increased (P < 0.05). Compared with the non-tracheal intubation group, the tracheal intubation and ECPR groups had significantly higher mortality rate and incidence rates of moderate-severe bronchopulmonary dysplasia and serious complications (P < 0.05). The incidence rates of grade Ⅲ-Ⅳ intracranial hemorrhage and retinopathy of prematurity (stage Ⅲ or above) in the tracheal intubation group were significantly higher than those in the non-tracheal intubation group (P < 0.05). CONCLUSIONS For preterm infants with a birth weight less than 1 500 g, the higher intensity of resuscitation in the delivery room is related to lower rate of antenatal corticosteroid therapy, lower gestational age, and lower birth weight. The infants undergoing tracheal intubation or ECRP in the delivery room have an increased incidence rate of adverse clinical outcomes. This suggests that it is important to improve the quality of perinatal management and delivery room resuscitation to improve the prognosis of the infants.

Abstract
The improvement of delivery room care, according to the 2015 International Consensus, may affect neonatal outcome, especially in very-low-birth-weight infants. We aimed to investigate the current practice of neonatal resuscitation by year and analyze the association with neonatal outcomes. A total of 8142 very-low-birth-weight infants, registered in the Korean Neonatal Network between 2014 and 2017 were included. A significant decreasing trend of intubation (64.5% vs 55.1%, P < 0.0001) and markedly increasing trend of positive pressure ventilation (PPV) (11.5% vs 22.9%, P < 0.0001) were noted. The annual PPV rate differed significantly by gestation (P < 0.0001). The highest level of resuscitation was also shown as an independent risk factor for mortality within 7 days and for bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), and periventricular leukomalacia. PPV and intubation were associated with significantly decreased risk of mortality and morbidities compared to epinephrine use. When considering association, the incidence of mortality within 7 days, IVH, PVL, and BPD or mortality showed significant differences by combination of year, gestational age, and level of resuscitation. According to updated guidelines, changes in the highest level of resuscitation significantly associated with reducing mortality and morbidities. More meticulous delivery room resuscitation focusing on extreme prematurity is needed.

Abstract
BACKGROUND Ventilated preterm infants are exposed to deviations from the intended arterial oxygen saturation range. Therefore, an automated control system was developed to rapidly modulate the fraction of inspired oxygen. The aim of this review is to compare the efficacy and safety of automated versus manual oxygen delivery control. METHODS In December 2020, we systematically searched four electronic databases; PubMed, Cochrane Library, Scopus, and Web of Science for eligible randomized controlled trials. We extracted and pooled data as mean difference and 95% confidence interval in an inverse variance method using RevMan software. RESULTS Thirteen trials were included in this systematic review and meta-analysis, enrolling 343 preterm infants on respiratory support. Automated oxygen control increased the time spent within the target arterial oxygen saturation range of 85-96% (MD = 8.96; 95% CI [6.26, 11.67], p<.00001), and 90-95% (MD = 18.25; 95% CI [4.58, 31.65], p = .008). In addition, it reduced the time of hypoxia (<80%); (MD = -1.24; 95% CI [-2.05, -0.43], p = .003), (MD = -0.82; 95% CI [-1.23, -0.41], p<.0001) with predetermined ranges of 85-96% and 90-95%, respectively. Automated control system reduced as well the time of hyperoxia (>98%) (MD = -0.99; 95% CI [-1.74, -0.25], p = .009) at intended range of 90-95%, and number of manual inspired oxygen fraction adjustments (MD = -2.82; 95% CI [-4.56, -1.08], p = .002). CONCLUSIONS Automated oxygen delivery is rapid and effective in controlling infants' oxygen saturation. It can be used to reduce the load over the nurses, but not to substitute the clinical supervision. Further long-term trials of large-scale are required to evaluate the prolonged clinical outcomes.

Abstract
OBJECTIVE To characterise the association between weekend (Saturday and Sunday) deliveries of very low birthweight (VLBW) infants and delivery room outcomes in the 'golden hour' after birth. DESIGN AND SETTING A retrospective cohort study using California Perinatal Quality Care Collaborative data from participating neonatal intensive care units. PATIENTS The study population after exclusions was 26 515 VLBW infants born in California from 2010 to 2016. MAIN OUTCOME MEASURES Delivery room outcomes assessed included: chest compressions, epinephrine, intubation prior to continuous positive airway pressure ventilation, 5 min Apgar <4, admission hypothermia and death within 12 hours. To adjust for potential confounders, we fit multivariate regression models controlling for two sets of infant, maternal and hospital characteristics. RESULTS Infants delivered on weekends were less likely to have been prenatally diagnosed with intrauterine growth restriction but were otherwise not significantly different in gestational age, ethnicity, sex or maternal risk factors than those born during weekdays. Caesarean deliveries were less common on weekends, while vaginal deliveries were consistent across all days. After adjusting for sex and race, weekend delivery was associated with delivery room chest compressions (OR: 1.12, 95% CI 1.02 to 1.24) and lower 5 min Apgar (OR: 1.11, 95% CI 1.01 to 1.21). CONCLUSION In this population-based study of VLBW infants, there was an increase in chest compressions for infants born on the weekend. More research is needed on the differences between populations born on weekdays versus weekends, and how these may contribute to observed associations.

Abstract
Background Sustained inflation (SI) during chest compression (CC = CC+SI) has been recently shown as an alternative method during cardiopulmonary resuscitation in neonates. However, the optimal peak inflation pressure (PIP) of SI during CC+SI to improve ROSC and hemodynamic recovery is unknown. Objective To examine if different PIPs of SI during CC+SI will improve ROSC and hemodynamic recovery in severely asphyxiated piglets. Methods Twenty-nine newborn piglets (1–3 days old) were anesthetized, intubated, instrumented and exposed to 30-min normocapnic hypoxia followed by asphyxia. Piglets were randomized into four groups: CC+SI with a PIP of 10 cmH2O (CC+SI_PIP_10, n = 8), a PIP of 20 cmH2O (CC+SI_PIP_20, n = 8), a PIP of 30 cmH2O (CC+SI_PIP_30, n = 8), and a sham-operated control group (n = 5). Heart rate, arterial blood pressure, carotid blood flow, cerebral oxygenation, and respiratory parameters were continuously recorded throughout the experiment. Results Baseline parameters were similar between all groups. There was no difference in asphyxiation (duration and degree) between intervention groups. PIP correlated positively with tidal volume (VT) and inversely with exhaled CO2 during cardiopulmonary resuscitation. Time to ROSC and rate of ROSC were similar between piglets resuscitated with CC+SI_PIP_10, CC+SI_PIP_20, and CC+SI_PIP_30 cmH2O: median (IQR) 75 (63–193) sec, 94 (78–210) sec, and 85 (70–90) sec; 5/8 (63%), 7/8 (88%), and 3/8 (38%) (p = 0.56 and p = 0.12, respectively). All piglets that achieved ROSC survived to four hours post-resuscitation. Piglets resuscitated with CC+SI_PIP_30 cmH2O exhibited increased concentrations of pro-inflammatory cytokines interleukin-1β and tumour necrosis factor-α in the frontoparietal cerebral cortex (both p<0.05 vs. sham-operated controls). Conclusion In asphyxiated term newborn piglets resuscitated by CC+SI, the use of different PIPs resulted in similar time to ROSC, but PIP at 30 cmH2O showed a larger VT delivery, lower exhaled CO2 and increased tissue inflammatory markers in the brain.

Abstract
AIMS Survival after delivery room cardiopulmonary resuscitation (DR-CPR) is not well characterized in full-term infants, and survival outcomes after DR-CPR have not been defined across the spectrum of gestation. The study objectives were to define gestational age (GA) specific survival following DR-CPR and to assess the association between GA and DR-CPR characteristics and survival outcomes. METHODS Retrospective cohort study of prospectively collected data in the American Heart Association Get With the Guidelines-Resuscitation registry. Newborn infants without congenital abnormalities who received greater than 1 min of chest compressions for DR-CPR were included. GA was stratified by categorical subgroups: ≥36 weeks; 33-356/7 weeks; 29-326/7 weeks; 25-286/7 weeks; 22-246/7 weeks. The primary outcome was survival to hospital discharge; the secondary outcome was return of circulation (ROC). RESULTS Among 1022 infants who received DR-CPR, 83% experienced ROC and 64% survived to hospital discharge. GA-stratified hospital survival rates were 83% (≥36 weeks), 66% (33-35 weeks), 60% (29-32 weeks), 52% (25-28 weeks), and 25% (22-24 weeks). Compared with GA ≥ 36 weeks, lower GA was independently associated with decreasing odds of survival (33-35 weeks: adjusted Odds Ratio [aOR] 0.46, 95% Confidence Interval [CI] 0.26-0.81; 29-32 weeks: aOR 0.40, 95% CI 0.23-0.69; 25-28 weeks: aOR 0.21, 95% CI 0.11-0.41; 22-24 weeks: aOR 0.06, 95% CI 0.03-0.10). CONCLUSIONS In this national registry of infants who received delivery room cardiopulmonary resuscitation (DR-CPR), 83% survived the event and two-thirds survived to hospital discharge. These results contribute to defining survival outcomes following DR-CPR across the continuum of gestation.

Abstract
Necrotizing enterocolitis (NEC) is a devastating morbidity usually seen in preterm infants, with extremely preterm neonates (EPT ≤28 weeks) considered at highest risk. Moderately preterm infants (MPT 28-34 weeks) constitute a large percentage of NICU admissions. In our retrospective data analysis of NEC in a single regional perinatal center, NEC was observed in 10% of extremely EPT and 7% of MPT, but only 0.7% of late-preterm/term admissions. There was an inverse relationship between postnatal age at onset of NEC and gestational age at birth. Among MPT infants with NEC, maternal hypertensive disorders (29%) and small for gestational age (SGA-15%) were more common than in EPT infants (11.6 and 4.6%, resp.). Congenital gastrointestinal anomalies were common among late preterm/term infants with NEC. SGA MPT infants born to mothers with hypertensive disorders are particularly at risk and should be closely monitored for signs of NEC. Identifying risk factors specific to each gestational age may help clinicians to tailor interventions to prevent NEC.

Abstract
OBJECTIVES To describe the frequency and extent of delivery room resuscitation and evaluate the association of delivery room resuscitation with neonatal outcomes in moderately preterm (MPT) infants. STUDY DESIGN This was an observational cohort study of MPT infants delivered at 290/7 to 336/7 weeks' gestational age (GA) enrolled in the Neonatal Research Network MPT registry. Infants were categorized into 5 groups based on the highest level of delivery room intervention: routine care, oxygen and/or continuous positive airway pressure, bag and mask ventilation, endotracheal intubation, and cardiopulmonary resuscitation including chest compressions and/or epinephrine use. The association of antepartum and intrapartum risk factors and discharge outcomes with the intensity of resuscitation was evaluated. RESULTS Of 7014 included infants, 1684 (24.0%) received routine care and no additional resuscitation, 2279 (32.5%) received oxygen or continuous positive airway pressure, 1831 (26.1%) received bag and mask ventilation, 1034 (14.7%) underwent endotracheal intubation, and 186 (2.7%) received cardiopulmonary resuscitation. Among the antepartum and intrapartum factors, increasing GA, any exposure to antenatal steroids and prolonged rupture of membranes decreased the likelihood of receipt of all levels of resuscitation. Infants who were small for GA (SGA) had increased risk of delivery room resuscitation. Among the neonatal outcomes, respiratory support at 28 days, days to full oral feeds and length of stay were significantly associated with the intensity of delivery room resuscitation. Higher intensity of resuscitation was associated with increased risk of mortality. CONCLUSIONS The majority of MPT infants receive some level of delivery room resuscitation. Increased intensity of delivery room interventions was associated with prolonged respiratory and nutritional support, increased mortality, and a longer length of stay.

Abstract
OBJECTIVE To examine outcomes of neonates based on the mode and intensity of resuscitation received in the delivery room (DR). STUDY DESIGN A retrospective study of 439 infants with birth weight ⩽1500 g receiving DR resuscitation at two hospital centers in Philadelphia, Pennsylvania. RESULTS Of 439 infants, 22 (5%) received routine care, 188 (43%) received noninvasive positive pressure ventilation (PPV) and 229 (52%) received endotracheal tube (ETT) intubation in the DR. Adjusted odds for respiratory distress syndrome was associated with lower rates in infants requiring lower intensity of DR resuscitation (P<0.001). Noninvasive PPV vs ETT was associated with decreased odds of developing intraventricular hemorrhage and retinopathy of prematurity (P<0.05). Routine vs noninvasive PPV or ETT had decreased odds of developing bronchopulmonary dysplasia (P<0.05). CONCLUSION Decreased intensity of DR resuscitation was associated with a decreased risk of specific morbidities.

Abstract
BACKGROUND Advanced levels of delivery room resuscitation in very low birth weight infants are reported to be associated with death and complications of prematurity. In resource limited settings, the need for delivery room resuscitation is often used as a reason to limit care in these infants. METHODS This was a review of delivery room resuscitation in very low birth weight infants born in a tertiary hospital in South Africa between 01 January 2013 and 30 June 2016. Outcomes included death and serious complications of prematurity. Advanced delivery room resuscitation was defined as the need for intubation, chest compressions or the administration of adrenaline. RESULTS A total of 1511 very low birth weight infants were included in the study. The majority (1332/1511 (88.2%) required oxygen in the delivery room. Face mask ventilation was needed in 45.2% (683/1511). Advanced delivery room resuscitation was only required in 10.6% (160/1511). More than half the infants who required advanced delivery room resuscitation died (89/160; 55.6%). Advanced delivery room resuscitation was required in significantly more infants <1000 grams at birth than those infants >1000 grams (83/539 (15.4%) vs 77/972 (7.9%) p < 0.001). Advanced delivery room resuscitation was significantly associated with a 5 minute Apgar score < 6 (OR 13.8 (95%CI 8.6-22.0), supplemental oxygen at day 28 (OR 2.2 (95% CI 1.4-3.9), metabolic acidosis (OR 2.3 (95% CI 1.1-4.8) and death (OR 1.9 95% CI 1.1-3.3). Other serious complications of prematurity were not associated with advanced delivery room resuscitation. Mortality was increased in infants with a low admission temperature (35.1 °C (SD 0.92) vs 36.1 °C (SD 1.4) (p < 0.001). CONCLUSION There was a high mortality rate associated with advanced delivery room resuscitation; however complications of prematurity were not increased in survivors..The need for advanced delivery room resuscitation alone should not be used as a predictor of poor outcome in very low birth weight infants. Survivors of advanced delivery room resuscitation should be afforded ventilatory support if required. Special care must be taken to avoid hypothermia in very low birth weight infants requiring resuscitation at birth.

ACTA ACUST UNITED AC 2017; 49:S0100-879X2016000700703. [PMID: 27356106 PMCID: PMC4926528 DOI: 10.1590/1414-431x20165258] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Accepted: 03/21/2016] [Indexed: 11/22/2022]
Abstract
Neonatal asphyxia can cause irreversible injury of multiple organs resulting in
hypoxic-ischemic encephalopathy and necrotizing enterocolitis (NEC). This injury is
dependent on time, severity, and gestational age, once the preterm babies need
ventilator support. Our aim was to assess the different brain and intestinal effects
of ischemia and reperfusion in neonate rats after birth anoxia and mechanical
ventilation. Preterm and term neonates were divided into 8 subgroups (n=12/group): 1)
preterm control (PTC), 2) preterm ventilated (PTV), 3) preterm asphyxiated (PTA), 4)
preterm asphyxiated and ventilated (PTAV), 5) term control (TC), 6) term ventilated
(TV), 7) term asphyxiated (TA), and 8) term asphyxiated and ventilated (TAV). We
measured body, brain, and intestine weights and respective ratios [(BW), (BrW), (IW),
(BrW/BW) and (IW/BW)]. Histology analysis and damage grading were performed in the
brain (cortex/hippocampus) and intestine (jejunum/ileum) tissues, as well as
immunohistochemistry analysis for caspase-3 and intestinal fatty acid-binding protein
(I-FABP). IW was lower in the TA than in the other terms (P<0.05), and the IW/BW
ratio was lower in the TA than in the TAV (P<0.005). PTA, PTAV and TA presented
high levels of brain damage. In histological intestinal analysis, PTAV and TAV had
higher scores than the other groups. Caspase-3 was higher in PTAV (cortex) and TA
(cortex/hippocampus) (P<0.005). I-FABP was higher in PTAV (P<0.005) and TA
(ileum) (P<0.05). I-FABP expression was increased in PTAV subgroup (P<0.0001).
Brain and intestinal responses in neonatal rats caused by neonatal asphyxia, with or
without mechanical ventilation, varied with gestational age, with increased
expression of caspase-3 and I-FABP biomarkers.

Abstract
BACKGROUND Delivery room resuscitation of very low birth weight infants can involve use of endotracheal or intravenous epinephrine. Data of the past 19 years were reviewed to identify the usage of epinephrine in delivery room and identify characteristics of these babies. METHODS Neonates with ≤1500g birthweight from January 1996 to August 2014 were reviewed. Infants born alive and admitted to NICU were eligible. Characteristics such as demographics, survival and outcomes were recorded. Variables significant at p≤0.1 among neonates receiving epinephrine were further analyzed via multiple logistic regressions. RESULTS Out of 5868 eligible neonates, 416 (7%) received epinephrine in the delivery room. The infants who received epinephrine were of lower estimated gestational age (25 vs. 28wk) and lower birth weight (746 vs. 980g). Gender, race and mode of delivery were comparable between the two cohorts. Survival was higher in non-epinephrine group (89.4 vs. 61.1%). Bacterial infection (24.3 vs. 18.4%) and combined grade 3 and 4 intraventricular hemorrhage (18.4 vs. 8.4%) were higher in epinephrine group. Use of epinephrine in the delivery room was associated with decreased survival even after controlling for birth weight, gestational age and low Apgar scores [Odd ratio - 0.48 with 95% CI (0.37-0.62), p<0.001]. CONCLUSION Neonates with lower birth weight and younger gestational age were more likely to receive epinephrine during resuscitation at birth. Use of epinephrine in delivery room was associated with lower survival and severe intraventricular hemorrhage among very low birth weight infants.

Chest Compressions during Sustained Inflations Improve Recovery When Compared to a 3:1 Compression:Ventilation Ratio during Cardiopulmonary Resuscitation in a Neonatal Porcine Model of Asphyxia. Neonatology 2017; 112:337-346. [PMID: 28768280 DOI: 10.1159/000477998] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2016] [Accepted: 06/06/2017] [Indexed: 11/19/2022]
Abstract
BACKGROUND Recently, sustained inflations (SI) during chest compression (CC) (CC+SI) have been suggested as an alternative to the current approach during neonatal resuscitation. No previous study compared CC+SI using CC rates of 90/min to the current 3:1 compression:ventilation ratio (C:V). OBJECTIVE To determine whether CC+SI versus a 3:1 C:V reduces the time to the return of spontaneous circulation (ROSC) and improves hemodynamic recovery in newborn piglets with asphyxia-induced bradycardia. INTERVENTION AND MEASUREMENTS Term newborn piglets were anesthetized, intubated, instrumented, and exposed to 45-min normocapnic hypoxia followed by asphyxia. Cardiopulmonary resuscitation (CPR) was initiated when the heart rate decreased to 25% of baseline. Piglets were randomized into 3 groups: CC during SI at a rate of 90 CC/min (SI+CC 90, n = 8), a 3:1 C:V using 90 CC and 30 inflations (3:1, n = 8), or a sham group (n = 6). Cardiac function, carotid blood flow, cerebral oxygenation, and respiratory parameters were continuously recorded throughout the experiment. RESULTS CC+SI significantly reduced the median (IQR) time of ROSC, i.e., 34 s (28-156 s) versus 210 s (72-300 s) in the 3:1 group (p = 0.048). CC+SI also significantly reduced the requirement for 100% oxygen, improved respiratory parameters, and resulted in a similar hemodynamic recovery. CONCLUSIONS CC+SI during CPR significantly improved ROSC in a porcine model of neonatal resuscitation. This is of considerable clinical relevance because improved respiratory and hemodynamic parameters potentially minimize morbidity and mortality in newborn infants.

Acta Paediatr 2016; 105:e142-50.

Abstract
AIM Standard resuscitation guidelines are based on data from a range of gestational ages. We sought to evaluate the effectiveness of our delivery room resuscitation protocol across a range of gestational ages in preterm infants born at <29 weeks. METHODS We performed an observational study of prospectively collected video recordings of 73 preterm infants. The percentage of bradycardic patients, time to reach target oxygen saturation and the extent of all interventions were compared between three gestational age groups: 22-24 weeks (n = 22), 25-26 weeks (n = 27) and 27-28 weeks (n = 24). RESULTS Although the same resuscitation protocol was followed for all infants, bradycardic infants born <25 weeks responded poorly and required significantly longer to reach oxygen saturation targets of >70%, >80% and >90% (p < 0.03). They required significantly more interventions and had higher rate of death (p < 0.05) and severe intraventricular haemorrhage (p < 0.03). Significantly lower heart rate and oxygen saturation values were found in infants with intraventricular haemorrhage. CONCLUSION Current recommendations for resuscitation may fail to achieve timely lung aeration in infants born at the borderline of viability, leading to higher mortality and morbidity. Sustained inflation and delayed cord clamping may be effective alternatives.

Abstract
Neonatal resuscitation is one of the most frequently performed procedures, and it is often successful if the ventilation applied is adequate. Over the last decade, interest in seeking objectivity in evaluating the infant's condition at birth or the adequacy and effect of the interventions applied has markedly increased. Clinical parameters such as heart rate, color, and chest excursions are difficult to interpret and can be very subjective and subtle. The use of ECG, pulse oximetry, capnography, and respiratory function monitoring can add objectivity to the clinical assessment. These physiological parameters, with or without the combination of video recordings, can not only be used directly to guide care but also be used later for audit and teaching purposes. Further studies are needed to investigate whether this will improve the quality of delivery room management. In this narrative review, we will give an update of the current developments in monitoring neonatal resuscitation.

Abstract
Aim Providing consistent levels of oxygen saturation (SpO2) for infants in neonatal intensive care units is not easy. This study explored how effectively the Auto-Mixer® algorithm automatically adjusted fraction of inspired oxygen (FiO2) levels to maintain SpO2 within an intended range in extremely low birth weight infants receiving supplemental oxygen without mechanical ventilation. Methods Twenty extremely low birth weight infants were randomly assigned to the Auto-Mixer® group or the manual intervention group and studied for 12 h. The SpO2 target was 85–93%, and the outcomes were the percentage of time SpO2 was within target, SpO2 variability, SpO2 >95%, oxygen received and manual interventions. Results The percentage of time within intended SpO2 was 58 ± 4% in the Auto-Mixer® group and 33.7 ± 4.7% in the manual group, SpO2 >95% was 26.5% vs 54.8%, average SpO2 and FiO2 were 89.8% vs 92.2% and 37% vs 44.1%, and manual interventions were 0 vs 80 (p < 0.05). Brief periods of SpO2 < 85% occurred more frequently in the Auto-Mixer® group. Conclusion The Auto-Mixer® effectively increased the percentage of time that SpO2 was within the intended target range and decreased the time with high SpO2 in spontaneously breathing extremely low birth weight infants receiving supplemental oxygen.

Abstract
The transition to newborn life in preterm infants is complicated by immature cardiovascular and respiratory systems. Consequently, preterm infants often require respiratory support immediately after birth. Although aeration of the lung underpins the circulatory transition at birth, positive pressure ventilation can adversely affect cardiorespiratory function during this vulnerable period, reducing pulmonary blood flow and left ventricular output. Furthermore, pulmonary volutrauma is known to initiate pulmonary inflammatory responses, resulting in remote systemic involvement. This review focuses on the downstream consequences of positive pressure ventilation, in particular, interactions between cardiovascular output and the initiation of a systemic inflammatory cascade, on the immature brain. Recent studies have highlighted that positive pressure ventilation strategies are precursors of cerebral injury, probably mediated through cerebral blood flow instability. The presence of, or initiation of, an inflammatory cascade accentuates adverse cerebral blood flow, in addition to being a direct source of brain injury. Importantly, the degree of brain injury is dependent on the nature of the initial ventilation strategy used.

Abstract
Bronchopulmonary dysplasia (BPD) is among the most common and serious sequelae of preterm birth. BPD affects at least one-quarter of infants born with birth weights less than 1500 g. The incidence of BPD increases with decreasing gestational age and birth weight. Additional important risk factors include intrauterine growth restriction, sepsis, and prolonged exposure to mechanical ventilation and supplemental oxygen. The diagnosis of BPD predicts multiple adverse outcomes including chronic respiratory impairment and neurodevelopmental delay. This review summarizes the diagnostic criteria, incidence, risk factors, and long-term outcomes of BPD.

Abstract
BACKGROUND There is no consensus or evidence as to whether a neuromuscular blocking agent should be used during the initial resuscitation of infants with congenital diaphragmatic hernia (CDH) in the labour ward. OBJECTIVE To determine if administration of a neuromuscular blocking agent affected the lung function of infants with CDH during their initial resuscitation in the labour ward. METHODS Fifteen infants with CDH were studied (median gestational age 38 weeks, range 34-41; birth weight 2,790 g, range 1,780-3,976). Six infants had undergone feto-endotracheal occlusion (FETO). Flow, airway pressure, tidal volume and dynamic lung compliance changes were recorded using a respiratory function monitor (NM3, Respironics). Twenty inflations immediately before, immediately after and 5 min after administration of a neuromuscular blocking agent (pancuronium bromide) were analysed. RESULTS The median dynamic lung compliance of the 15 infants was 0.22 ml/cm H2O/kg (range 0.1-0.4) before and 0.16 ml/cm H2O/kg (range 0.1-0.3) immediately after pancuronium bromide administration (p < 0.001) and remained at a similar low level 5 min after pancuronium bromide administration. The FETO compared to the non-FETO infants had a lower median dynamic compliance both before (p < 0.0001) and 5 min after pancuronium administration (p < 0.001) and required significantly longer durations of ventilation (p = 0.004), supplementary oxygen (p = 0.003) and hospitalisation (p = 0.007). CONCLUSIONS Infants with CDH, particularly those who have undergone FETO, have a low lung compliance at birth, and this is further reduced by administration of a neuromuscular blocking agent.
