Preterm Infants Who Did Not Need Positive Pressure Ventilation Had a Lower Heart Rate Immediately After Birth Than Healthy Term Infants. Acta Paediatr 2025. [PMID: 40205814 DOI: 10.1111/apa.70079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 03/07/2025] [Accepted: 03/26/2025] [Indexed: 04/11/2025]
Abstract
AIM Our aim was to use electrocardiograms immediately after birth to determine the heart rates of healthy newborn infants by gestational age and mode of delivery. METHODS This prospective observational study was performed in two Norwegian hospitals from March 2019 to June 2021. We included infants with gestational ages of ≥ 28 weeks and no need for positive pressure ventilation. Continuous heart rate data were collected using dry electrode technology and were used to create percentile charts and compare heart rates by groups. RESULTS We enrolled 214 preterm and 2191 term newborn infants. The median (quartiles) heart rate at 60 s of age was 166 (150-181) beats per minute for preterm infants and 174 (158-187) for term infants (p < 0.05). Term infants born using vacuum extraction, forceps or emergency Caesarean sections had significantly higher heart rates than term infants born by unassisted vaginal deliveries or planned Caesarean sections. The median heart rates of the groups were all within the normal range. CONCLUSION This study provided normative heart rate data for healthy newborn infants, by gestational age and delivery mode. Although the differences between the groups were statistically significant, they were of limited clinical significance and would not support changes in neonatal resuscitation measures.

Video-Recorded Airway Suctioning of Clear and Meconium-Stained Amniotic Fluid and Associated Short-Term Outcomes in Moderately and Severely Depressed Preterm and Term Infants. CHILDREN (BASEL, SWITZERLAND) 2023; 11:16. [PMID: 38255330 PMCID: PMC10814005 DOI: 10.3390/children11010016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/11/2023] [Accepted: 12/20/2023] [Indexed: 01/24/2024]
Abstract
BACKGROUND The aim of this study was to investigate delivery room airway suctioning and associated short-term outcomes in depressed infants. METHODS This is a single-centre prospective observational study of transcribed video recordings of preterm (gestational age, GA < 37 weeks) and term (GA ≥ 37 weeks) infants with a 5 min Apgar score ≤ 7. We analysed the association between airway suctioning, breathing, bradycardia and prolonged resuscitation (≥10 min). For comparison, non-suctioned infants with a 5 min Apgar score ≤ 7 were included. RESULTS Two hundred suction episodes were performed in 19 premature and 56 term infants. Breathing improved in 1.9% of premature and 72.1% of term infants, and remained unchanged in 84.9% of premature and 27.9% of term infants after suctioning. In our study, 61 (81.3%) preterm and term infants who were admitted to the neonatal intensive care unit experienced bradycardia after airway suctioning. However, the majority of the preterm and more than half of the term infants were bradycardic before the suction procedure was attempted. Among the non-airway suctioned infants (n = 26), 73.1% experienced bradycardia, with 17 non-airway suctioned infants being admitted to the neonatal intensive care unit. There was a need for resuscitation ≥ 10 min in 8 (42.1%) preterm and 32 (57.1%) term infants who underwent airway suctioning, compared to 2 (33.3%) preterm and 19 (95.0%) term infants who did not receive airway suctioning. CONCLUSIONS In the infants that underwent suctioning, breathing improved in most term, but not preterm infants. More non-suctioned term infants needed prolonged resuscitation. Airway suctioning was not directly associated with worsening of breathing, bradycardia, or extended resuscitation needs.
