The Analgesic Efficacy of Pericapsular Nerve Group (PENG) Block in Patients Undergoing Primary Total Hip Arthoplasty:

Diakonie-Klinikum Stuttgart110 enrolled

Overview

The aim of this study is to investigate the analgesic efficacy of the pericapsular nerve group (PENG) block during the implantation of hip endoprostheses. The study is designed as a prospective randomized double-blind study and the study participants were randomized into 2 arms and either 20 ml ropivacaine 0.5% (verum group) or 20 ml physiological saline solution (placebo group) will be applied.

Outcomes

Primary Outcomes

Rate of postoperative opioid administration

The primary objective is to investigate the influence of the PENG block on the need for postoperative ntravenously opioid administration within the first hour in the recovery room.

Time frame: 60 minutes after arrival in the recovery room

Secondary Outcomes

Quantity of total opioid consumption

Assessment of total opioid consumption until second postoperative day in both arms

Time frame: until the evening of the second postoperative day

Intensity of postoperative pain

Subjective perception of postoperative pain, using the numeric rating scale.

Time frame: until the evening of the second postoperative day

Intensity of postoperative nausea and vomiting

Assessment of postoperative nausea/vomiting using the PONV Score

Time frame: until the evening of the second postoperative day

Postoperative recovery

Assessment of postoperative recovery using the QoR15 score

Time frame: until the evening of the second postoperative day
