Pericapsular nerve group block in hip surgery. An alternative that goes beyond what we know?

ABSTRACT

Hip fracture is a pathology usually observed in older patients, prone to complications and increased morbidity and mortality during hospital admission. The PENG (Pericapsular Nerve Group) block has recently been described to provide higher quality analgesia, favoring early ambulation. The literature search was carried out from November 2018 to July 2021 with the following keywords pericapsular nerve group block and PENG block. Studies conducted in the pediatric population or in adults with an indication other than hip surgery were excluded; obtaining 18 articles to read in full text. The analyzed studies had positive results in favor of performing the PENG block in hip surgery. Unfortunately, the current evidence is insufficient to be able to integrate the results obtained and draw conclusions about the effectiveness and safety of the PENG block.
