Background/AimsAs little as 30 minutes of exposure to anesthetic and sedative agents may adversely affect the developing brain. Safe, humane management of critically ill infants requires the use of sedative agents, often for prolonged periods. We sought to identify two comparable groups of critical care patients who did or did not receive sedatives, with the aim of designing a long-term neurodevelopment follow-up study. This feasibility study aimed to determine if two comparable groups could be found.MethodsInfants with respiratory diagnoses having noninvasive ventilation without sedation (Group C) or intubation and ventilation with sedation (Group S) were identified by chart review. Charts of patients fulfilling the above inclusion criteria were searched for exclusion criteria including neurological disease, extreme prematurity, congenital cardiac disease, and genetic anomalies. Data were extracted to score pediatric severity of illness scores (PRISM and PELOD) for each patient. These scores were then compared using the absolute scores and by risk strata.ResultsGroup S included 33 patients and Group C had 39. The absolute PRISM and PELOD scores were different between groups. Comparing the groups in three risk strata (PRISM greater or less than 5 or 10), there were no significant differences between groups.ConclusionIt is not possible to randomize infants to sedation or no sedation to investigate neurodevelopmental outcomes. This phase of the project aimed to determine the comparability of two groups of PICU patients. These findings indicate that these groups could be enrolled as exposed and control subjects in an outcomes study.© 2018 John Wiley & Sons Ltd.
