Is intranasal dexmedetomidine superior to oral chloral hydrate for procedural sedation in children: A systematic review.

BACKGROUND

This systematic review was undertaken to compare the benefits of intranasal dexmedetomidine (IND) versus oral chloral hydrate (OCH) in the pediatric age group undergoing procedural sedation analgesia (PSA). Randomized clinical trials (RCT) of the various studies done over the years were taken up and analyzed. Since IND has the additional advantages of a faster onset of action, greater success with a single bolus dose, and enhanced recovery, this systematic review was conducted to prove the superiority of IND over OCH in pediatric PSA.

OBJECTIVE

To compare the efficacy of IND versus OCH for PSA in pediatric patients.

SEARCH STRATEGY: We searched the electronic databases from August 2012 to September 2019 without language restrictions.

DESIGN AND SELECTION CRITERIA: A review of 10 RCTs on the use of IND and OCH for PSA in the pediatric age group for a variety of diagnostic procedures was done and the superiority of IND as per the sedation time and adverse effects were analyzed.

RESULTS

Out of the RCTs considered, six trials were a direct comparison between OCH and IND which showed that IND had a faster onset of action, improved recovery characteristics with better return to baseline physical activity on the same day of the procedure. When compared to OCH, IND showed no evidence of second-dose requirement and no record of postoperative nausea and vomiting (PONV).

CONCLUSION

This systematic review revealed that IND is superior to OCH for PSA in the pediatric age group and proved to be safe and effective with better recovery characteristics.
