Regional Nerve Block for Upper Extremity Surgery in Patients With Sarcopenia

Condition(s) studied

Investigational drug(s) / intervention(s)

sarcopenia: Patients identified with sarcopenia based on preoperative muscle assessment.

Non-sarcopenia: Patients with normal muscle mass based on preoperative muscle assessment.

General Anesthesia: received general anesthesia alone

Nerve Block: general anesthesia combined with nerve block

Study summary

The goal of this observational study is to learn about the impact of sarcopenia (muscle loss) on the efficacy of regional nerve blocks and postoperative recovery in patients undergoing upper extremity surgery. The main questions it aims to answer are:

1. Does sarcopenia affect the onset time and success rate of peripheral nerve blocks?
2. How does sarcopenia influence postoperative pain control and opioid consumption compared to patients receiving pure general anesthesia?

Participants will undergo a preoperative muscle assessment, which includes a chair stand test and a brief ultrasound of the thigh muscle. Researchers will then observe and record their nerve block onset time (if applicable), postoperative pain scores, and recovery metrics during their hospital stay up to postoperative day 2.

Eligibility

Primary outcome measure(s)

• time to first rescue analgesia — From the completion of surgery up to Postoperative Day 2
