Abstract:
INTRODUCTION:Although ketamine is one of the commonest medications used in procedural sedation of children, to our knowledge, there is currently no published report on predictors of respiratory adverse events during ketamine sedation in Asian children. We aimed to determine the incidence of and factors associated with respiratory adverse events in children undergoing procedural sedation with intramuscular (IM) ketamine in a paediatric emergency department (ED) in Singapore.
METHODS:A retrospective analysis was conducted of all children who underwent procedural sedation with IM ketamine in the paediatric ED between 1 April 2013 and 31 October 2017. Demographics and epidemiological data, including any adverse events and interventions, were extracted electronically from the prospective paediatric sedation database. The site of procedure was determined through reviewing medical records. Descriptive statistics were used for incidence and baseline characteristics. Univariate and multivariate logistic regression analyses were performed to determine significant predictors.
RESULTS:Among 5,476 children, 102 (1.9%) developed respiratory adverse events. None required intubation or cardiopulmonary resuscitation. Only one required bag-valve-mask ventilation. The incidence rate was higher in children aged less than three years, at 3.6% compared to 1.0% in older children (odds ratio [OR] 3.524, 95% confidence interval [CI] 2.354-5.276; p < 0.001). Higher initial ketamine dose (adjusted OR 2.061, 95% CI 1.371-3.100; p = 0.001) and the type of procedure (adjusted OR 0.190 (95% CI 0.038-0.953; p = 0.044) were significant independent predictors.
CONCLUSION:The overall incidence of respiratory adverse events was 1.9%. Age, initial dose of IM ketamine and type of procedure were significant predictors.
