Factors associated with prolonged duration of ultrasound-guided brachial plexus block for the upper limb fracture surgery: a cross-sectional study.

ABSTRACT:

Background

Previous studies of factors associated with prolonged duration of ultrasound-guided brachial plexus block have included multiple surgical procedures or multiple anesthetic approaches, all of which are important confounders, and there is no study based on a single method of anesthesia exploring the factors affecting the resolution of brachial plexus block during upper limb surgery, especially in Asians. This study aimed to identify the risk factors affecting the prolonged duration of US-guided brachial plexus block in American Society of Anesthesiologists (ASA) I-II grade patients to improve postoperative analgesia.

Methods

This study enrolled patients scheduled to undergo surgery for upper limb fracture in Anting Hospital, Shanghai from May 2021 to September 2021.
