Pectoral nerve block in anesthesia for modified radical mastectomy: A meta-analysis based on randomized controlled trials.

ABSTRACT:

Background

Many types of regional nerve blocks have been used during anesthesia for modified radical mastectomy. In recent years, the use of pectoral nerve (PECS) block has gained importance in postoperative analgesia, but there are still controversies regarding its efficacy. There is especially no consensus on the optimal type of PECS block to be used. Herein, we attempt to evaluate the analgesic efficacy of the PECS block after radical mastectomy.

Methods

We searched PubMed, EMBASE, and the Cochrane library for randomized controlled trials (RCTs) for studies regarding PECS versus general anesthesia (GA) that were published prior to May 31, 2018. Outcome measures such as intra- and postoperative consumption of opioids, postoperative nausea and vomiting (PONV), need for post
