Systematic review demonstrates dexmedetomidine reduces postoperative junctional ectopic tachycardia in pediatric cardiac surgery, suggesting potential recovery benefits.
In prospective pediatric cardiac surgery trials, prophylactic dexmedetomidine was associated with reduced postoperative JET, supported by moderate-certainty evidence. While dexmedetomidine may help facilitate earlier recovery, its impact on secondary outcomes remains suggestive rather than definitive due to low evidence certainty. Future large-scale, multicenter randomized trials are required to confirm if these potential benefits translate into consistent clinical improvements.
