Ultrasound-guided nerve block anesthesia improves perioperative pain in patients undergoing free flap reconstruction for head-and-neck tumor: a randomized, controlled trial.

ABSTRACT:

Objective

The study attempted to explore the postoperative pain control of ultrasound-guided iliac fascia and trigeminus block anesthesia among patients undergoing free flap reconstruction for head-and-neck tumors.

Methods

This research implemented a prospective, double-blinded, randomized, and placebo-controlled clinical trial. Patients between 18 and 85 years who had accepted a radical head-and-neck tumor resection while simultaneously undergoing the vascularized anterolateral femoral free flap reconstruction for the surgical coloboma were recruited. The subjects were randomly divided into nerve block and blank groups. Faciocervical pain while speaking was the primary outcome variable. It was measured using the visual analog scale (VAS) during the perioperative period up t
