Overview
Brief Summary
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.

Intervention: Ropivacaine
Placebo Group
20 ml physiological saline
Intervention: Physiological saline
Outcomes
Primary Outcomes
Rate of postoperative opioid administration
Time Frame: 60 minutes after arrival in the recovery room
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.
Secondary Outcomes
- Quantity of total opioid consumption(until the evening of the second postoperative day)
- Intensity of postoperative pain(until the evening of the second postoperative day)
- Intensity of postoperative nausea and vomiting(until the evening of the second postoperative day)
- Postoperative recovery(until the evening of the second postoperative day)
