Summary

This randomized double-blind controlled clinical trial aims to evaluate the efficacy and safety of combining Dexmedetomidine with Desflurane in patients undergoing elective laparoscopic colectomy. The study will assess whether the combination can reduce Desflurane consumption, improve intraoperative hemodynamic stability, and enhance postoperative recovery compared to Desflurane alone.

Detailed description

Dexmedetomidine, a selective alpha-2 adrenergic agonist, has sedative and analgesic properties without significant respiratory depression. Desflurane, a volatile anesthetic with low blood-gas solubility, allows rapid induction and emergence. Combining these two agents may provide anesthetic-sparing effects and promote faster postoperative recovery under ERAS protocols. This study will enroll 40 adult patients undergoing elective laparoscopic colectomy at Tam Anh General Hospital, Vietnam. Participants will be randomized into two groups: Dexmedetomidine + Desflurane versus Desflurane alone. The primary outcome is average Desflurane consumption per hour, with secondary outcomes including hemodynamic parameters, Fentanyl use, emergence quality, and incidence of postoperative nausea and vomiting.

Conditions

• Colorectal Neoplasms

Interventions

Type	Name	Description
DRUG	Dexmedetomidine + Desflurane	Dexmedetomidine bolus 1 µg/kg IV over 15 minutes before induction, followed by continuous infusion 0.5 µg/kg/h during surgery. Desflurane administered at 1 MAC with EtControl mode.
DRUG	Desflurane + Normal Saline	Normal saline infusion with identical timing and volume as the intervention group. Desflurane administered at 1 MAC with EtControl mode.
