Evaluation of the safety of using propofol for paediatric procedural sedation: A systematic review and meta-analysis

Propofol is one of the most widely used drugs for paediatric procedural sedation owing to its known advantages, but some concerns remain regarding respiratory and/or cardiac complications in patients receiving propofol. Although a considerable number of randomised controlled clinical trials (RCTs) have been conducted to compare it with other sedative agents or opioids for children undergoing various procedures, propofol is still being used off-label for this indication in many countries. We performed a systematic review and meta-analysis of those RCTs to provide an overall summation of evidence that can potentially be considered for further regulatory decisions, including reimbursement policies. We searched for RCTs in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from their inception to January 31, 2018. Our meta-analysis of 30 RCTs confirmed that propofol sedation had advantages in recovery time when compared with other drugs, without excessive concerns for cardiovascular or respiratory adverse events. Its safety profile regarding coughing, nausea or vomiting, and emergence delirium was also similar to that of other drugs. The overall evidence suggests that propofol sedation for paediatric procedures should be considered more positively in the context of regulatory decisions.
