Objectives: Determine the incidence of apnea in preterm and term infants after deep sedation (DS) compared with general anesthesia (GA).
Methods: A retrospective chart review was performed on infants who underwent elective DS or GA from January 2008 to December 2013, were <60 weeks postmenstrual age if preterm or <50 weeks postmenstrual age if term, and were monitored for apnea as inpatients after DS or GA. Gestational age, postmenstrual age, chronologic age, anesthetic and sedative medications, procedure indication, and postsedation events were collected.
Results: There were 61 DS encounters (24 preterm and 37 term) and 175 GA encounters (120 preterm and 55 term) that met inclusion criteria. No recorded apneic events in either preterm or term infants were recorded after DS. After GA, 1.7% of infants had apneic events (2.5% preterm and 0 term; = .57 versus DS). All events occurred within 2 hours of monitoring in recovery.
Conclusions: None of the infants had apnea after DS. Rates from the literature would suggest that 2 to 6 of the preterm DS subjects should have experienced postsedation apnea. Sampled GA subjects had a rate of 2.5% in preterm infants exhibiting apnea after GA. Although the post-DS apnea rate is lower than what has been previously published, the small sample size and limitations of a retrospective design prevent us from directing a change in postsedation monitoring recommendations. However, we do support the need for prospective studies with strict monitoring criteria to reveal the true risk of post-DS apnea.

Reimagining apnea monitoring in the neonatal ICU.
Curr Opin Pediatr
December 2024
Division of Neonatology, Montreal Children's Hospital, McGill University Health Center, Montreal, Quebec, Canada.
Purpose Of Review: This review outlines the prevalence and complications of apneas and intermittent hypoxemic events in preterm infants, examines current monitoring limitations in neonatal ICUs (NICUs), and explores emerging technologies addressing these challenges.
Recent Findings: New evidence from the Prematurity-Related Ventilatory Control (Pre-Vent) study, which analyzed cardiorespiratory data from 717 extremely preterm infants, exposes the varying frequency, duration, and severity of apneas, intermittent hypoxemia, bradycardias, and periodic breathing during hospitalization, and highlights the negative impact of intermittent hypoxemia on pulmonary outcomes at discharge. Although traditional monitoring methods cannot differentiate between apnea types and quantify their burden, recent advancements in sensor technologies and data integration hold promise for improving real-time detection and evaluation of apneas in the NICU.
Subpial hemorrhage: A rare and underrecognized site of intracranial hemorrhage in neonates.

Subpial hemorrhage (SPH) is a rare but significant cause of neonatal seizures and respiratory distress, primarily affecting full-term infants without apparent risk factors. We report the case of a full-term newborn who presented with recurrent episodes of apnea, desaturation, and seizures shortly after birth. MRI revealed an acute hemorrhagic collection in the left temporal region, accompanied by cortical cytotoxic edema.

Aims: To retrospectively evaluate the effect of a sequential swallow training programme (SSTP) consisting of nonnutritive sucking (NNS), modified feeding posture, oral sensory-motor intervention and breath exercise on the independent oral feeding transition and coordination of suck-swallow-breath (SSB) functions in preterm infants.
Methods: Sixty preterm infants received SSTP intervention and sixty infants receiving NNS were set as control. The feeding performance and SSB coordination were assessed using POFRAS and NOMAS scales.

Aim: We evaluated whether sample entropy of heart rate time series could serve as a biomarker for guiding caffeine cessation in preterm infants treated for apnoea of prematurity (AOP). We also assessed associations of sample entropy with weeks of gestation, clinical morbidity, AOP frequency and caffeine reinitiation.
Methods: We conducted a prospective single-centre study at the University Children's Hospital Basel, Switzerland, from July 2019 to June 2020.
