Clinical effect of dexmedetomidine combined with sufentanil on postoperative analgesia for transthoracic device closure of ventricular septal defects in children with ultrafast track anesthesia.

The combination of 0.04 μg/kg/h dexmedetomidine and 0.04 μg/kg/h sufentanil intravenous analgesia was more effective than the other two analgesic strategies in children who underwent transthoracic device closure of ventricular septal defects (VSDs) with ultrafast track anesthesia.
