Risk Factors for Apnea in Children Presenting With Out-of-Hospital Seizure (original) (raw)

Pediatric Emergency Care, 2014

Abstract

This study aimed to quantify risk factors for apnea in children 0 to 5 years of age with out-of-hospital seizure. This is a retrospective study of pediatric patients with seizure transported by paramedics to the pediatric emergency department (PED) of a tertiary center from July 2008 to June 2009. Patients with traumatic injury and those with another diagnosis after PED evaluation were excluded. We evaluated the effect of field diazepam and other potential risk factors on the occurrence of apnea, defined as the need for airway management, that is, bag-mask ventilation by paramedics or bag-mask ventilation or intubation by PED staff within 30 minutes of arrival. There were 336 pediatric patients meeting inclusion criteria. The median age was 1.9 years (interquartile range,1.3-3.0 years); 193 patients (57%) were male. Fifty-four patients (16%) were treated with diazepam before PED arrival. There were 28 apneic events (8.3%). The adjusted relative risk for apnea given diazepam in the field by any route was 10.2 (95% confidence interval, 3.9-21.8; P < 0.0001), adjusted for age and seizure on arrival. Persistent seizure on PED arrival was also highly associated with apnea, with an adjusted relative risk of 15.8 (95% confidence interval, 6.5-28.9; P < 0.0001). Field treatment with diazepam and seizing at the time of PED arrival are associated with the occurrence of apnea in children 0 to 5 years of age with out-of-hospital seizure. Larger studies are needed to determine what other factors may contribute to this risk.
