Abstract
BACKGROUND
Better understanding of risk factors for adverse events during monitored anaesthesia care (MAC) for paediatric gastrointestinal endoscopy may improve outcome in children.
OBJECTIVES
To identify the prevalence and predictors of adverse events during MAC for paediatric endoscopy.
DESIGN
An observational study.
SETTING
Tertiary university hospital, single-centre cohort, from January 2010 to August 2016.
PATIENTS
The prospectively collected electronic anaesthetic records of 3435 children aged up to 16 years who underwent diagnostic gastrointestinal endoscopy under MAC were analysed retrospectively. Children with an American Society of Anesthesiologists' physical status at least 4, and those requiring mechanical ventilation and therapeutic or urgent endoscopy were excluded.
MAIN OUTCOME MEASURES
The prevalence and predictors of adverse events during MAC for paediatric gastrointestinal endoscopy, with particular reference to the use of different anaesthetic or sedative agents.
RESULTS
Mean ± SD age of the children was 8.5 ± 4.4 years. The incidences of adverse events and adverse respiratory events were 3.4 and 3.3%, respectively. Multivariate analysis identified 12 independent predictors: age [odds ratio (OR) 0.92, P = 0.002], children's size for example underweight (OR 1.78, P = 0.039), overweight (OR 2.20, P = 0.039), (morbid) obesity (OR 4.25, P = 0.006), presence of respiratory comorbidities (OR 8.18, P < 0.001), recent respiratory infection (OR 23.55, P < 0.001) or both (OR 17.46, P < 0.001), neurological comorbidities (OR 2.18, P = 0.007), upper gastrointestinal endoscopy (OR 5.66, P < 0.001), propofol co-administration with ketamine (OR 10.34, P < 0. 001) or after sevoflurane induction (OR 44.95, P < 0.001), and propofol induction dose (OR 18.97, P < 0.001). Posthoc secondary analyses revealed a significantly higher risk of adverse events (OR 3.9, P < 0.0001) and also significantly more respiratory comorbidities and respiratory infections (P < 0.0001) in children aged less than 2 years when compared with children aged at least 2 years. No cardiovascular events were observed and outcome was uneventful.
CONCLUSION
The present cohort demonstrated the feasibility and safety of MAC for paediatric gastrointestinal endoscopy by an experienced team. Although adverse events occurred rarely, their predictive factors were clinically identifiable. Applying this information in risk assessment and modifying anaesthetic management accordingly could improve outcome.
