ABSTRACT
Objectives: Characterize short-term outcomes of late preterm and term infants who received positive pressure ventilation in the delivery room and compare these with infants who did not receive resuscitation at birth. Study Design: Single center retrospective cohort study of infants born between 35 0/7 and 41 6/7 weeks' gestation in 2019. Baseline characteristics and outcomes of infants who received positive pressure ventilation were compared with controls who did not receive delivery room ventilation. The primary outcome was neonatal intensive care unit admission; secondary outcomes included multiple hospital morbidities and interventions. Results: Among 202 infants who received delivery room positive pressure ventilation, 77 (38.1%) received ≤1 min, and 125 (61.9%) received >1 min of positive pressure ventilation. Neonatal intensive care unit admission directly following resuscitation was more common in the ventilation cohort (33%) compared with controls (1.5%), p ≤ 0.0001. After initial admission to the newborn nursery, intensive care unit transfer rates were similar in the positive pressure ventilation cohort (4%) and controls (5%). Antibiotic exposure, hypoxic ischemic encephalopathy, respiratory support in the neonatal intensive care unit, and pneumothorax were more common in the ventilation cohort. The composite outcome of any post-delivery complication occurred in 45% of positive pressure ventilation-exposed infants, compared to 15.8% of control infants (<0.0001); this was more common following >1 min (52.8%) than ≤1 min positive pressure ventilation (32.5%), p = 0.002. Conclusion: Post-delivery complications are common following delivery room positive pressure ventilation, emphasizing the need for post-resuscitation monitoring in either the neonatal intensive care unitor newborn nursery setting.
ABSTRACT
BACKGROUND: A respiratory function monitor (RFM) provides real-time positive pressure ventilation feedback. Whether providers use RFM during neonatal resuscitation is unknown. METHODS: Ancillary study to the MONITOR(NCT03256578) randomised controlled trial. Neonatal resuscitation leaders at two centres wore eye-tracking glasses, and visual attention (VA) patterns were compared between RFM-visible and RFM-masked groups. RESULTS: 14 resuscitations (6 RFM-visible, 8 RFM-masked) were analysed. The median total gaze duration on the RFM was significantly higher with a visible RFM (29% vs 1%, p<0.01), while median total gaze duration on other physical objects was significantly lower with a visible RFM (3% vs 8%, p=0.02). Median total gaze duration on the infant was lower with RFM visible, although not statistically significantly (29% vs 46%, p=0.05). CONCLUSION: Providers' VA patterns differed during neonatal resuscitation when the RFM was visible, emphasising the importance of studying the impact of additional delivery room technology on providers' behaviour.
