Objectives

Narrative objectives1

In this study, we will evaluate the safety of ultrasound-guided maxillary nerve block and inferior alveolar nerve block in patients undergoing vertical jaw deformities by measuring blood levels of local anesthetics and randomly assigning subjects to the block group and the control group who will not undergo block intervention. We evaluate the effects on the number of analgesics required (primary outcome), pain score, analgesic effect, and quality of postoperative recovery (secondary outcome) for 24 hours after the block. The purpose of this study is to establish a safe and effective analgesic method for orthognathic surgery.

Assessment

Primary outcomes

The number of times rescue analgesics are used in the 24 hours following the block.

Key secondary outcomes

After the block (1, 5, 15, 30, 60 min), levobupivacaine blood level, NRS at/after return, intraoperative opioid (fentanyl, remifentanil) use, pre-/postoperative QoR-40 scores, time to first analgesic use after discharge, complications of ner ve block (local anesthetic systemic toxicity, hematoma, local infection), respiratory complications in the first 24 hours after surgery

Interventions/Control_1

In the block group, bilateral ultrasound-guided maxillary and inferior alveolar nerve blocks are performed after induction of general anesthesia, and 5 mL each of 0.375% levobupivacaine is administered for a total of 20 mL. The time at which all four nerve blocks are completed is set as 0 minutes, and arterial blood samples are collected at 1, 5, 15, 30, and 60 minutes to measure the blood concentration of levobupivacaine.

Interventions/Control_2

In the control group, no block intervention was performed and no arterial blood sampling was done.
