Effectiveness of Low-Volume Versus High-Volume Ropivacaine for Ultrasound-Guided Maxillary Nerve Block in Double-Jaw Surgery: A Randomized Non-inferiority Trial.

ABSTRACT:

Background

Ultrasound-guided maxillary nerve block (UGMNB) is applied in oral and maxillofacial surgery to improve perioperative analgesia, decrease the risk of postoperative nausea and vomiting, and enhance recovery. However, the optimum volume of ropivacaine used for UGMNB is undetermined. Thus, it was hypothesized that in patients undergoing double-jaw surgery, low- and high-volume ropivacaine reduces perioperative pain with similar efficacy.

Methods

Adults undergoing double-jaw surgery were enrolled in a randomized non-inferiority trial to receive a bilateral single-injection UGMNB with 2 mL (low-volume [LV] group) or 5 mL (high-volume [HV] group) of 0.375% ropivacaine on each side. A visual analog scale (VAS) score for maxillary pain at 2 h postoperatively was taken as
