Key result
Prophylactic perioperative dexmedetomidine significantly reduced the incidence of postoperative junctional ectopic tachycardia (OR 0.35) in pediatric patients undergoing cardiac surgery, but had no significant effect on acute kidney injury.
Why the study?
Does prophylactic perioperative dexmedetomidine reduce postoperative junctional ectopic tachycardia and acute kidney injury in pediatric patients undergoing cardiac surgery?
Meta-Analysis (n=1,851)
Does prophylactic perioperative dexmedetomidine reduce postoperative junctional ectopic tachycardia and acute kidney injury in pediatric patients undergoing cardiac surgery?
Odds Ratio: 0.35 (95% CI 0.22–0.53)
Absolute Event Rate: 5.1% vs 12.1%
p-value: p=<0.00001
Prophylactic perioperative dexmedetomidine significantly reduces the incidence of postoperative junctional ectopic tachycardia in pediatric patients undergoing cardiac surgery, though it does not significantly affect acute kidney injury or mortality.

Supports dexmedetomidine prophylaxis to lower junctional ectopic tachycardia risk after pediatric cardiac surgery; extends Level 1 evidence from prior trials.
Li et al. (2018) conducted a meta-analysis in Congenital heart disease requiring cardiac surgery (n=1,851). Dexmedetomidine vs. Placebo, no drug, or other drugs (e.g., amiodarone) was evaluated on Incidence of postoperative junctional ectopic tachycardia (JET) (OR 0.35, 95% CI 0.22 to 0.53, p=<0.00001). Prophylactic perioperative dexmedetomidine significantly reduced the incidence of postoperative junctional ectopic tachycardia (OR 0.35) in pediatric patients undergoing cardiac surgery, but had no significant effect on acute kidney injury.
