Efficacy and Safety of Pericapsular Nerve Group (PENG) Block for Patients Undergoing Shoulder Surgery

Significant pain after shoulder surgery induce worse experience and may delay recovery of patients undergoing shoulder surgery. Interscalene brachial plexus block (ISB) is a common and rapid-onset procedure for pain control of patients undergoing shoulder surgery. However, the high incidence of adverse events such as hemidiaphragmatic paresis, horner syndrome after interscalene block threatened patients' safety and raised clinicians' concerns on them. Hence, effective analgesia alternatives to interscalene block with less complications are needed.

Recently, pericapsular Nerve Group (PENG) Block, a new technology is reported for block of articular branches of the shoulder and well pericapsular spread around the glenohumeral joint. In this study, we assume that PENG Block may offer a noinferior analgesia and less incidence of nerve block related adverse events compared with ISB.
