Trial Outcomes & Findings for Deep Versus Moderate Muscle Relaxation During Laparoscopic Donor Nephrectomy in Enhancing Postoperative Recovery (NCT NCT02838134)

NCT ID: NCT02838134

Last Updated: 2019-09-19

Results Overview

The QoR-40 is a validated assessment tool for measuring a patient's self-assessed quality of recovery after surgery. It consists of 40 questions measuring 5 dimensions: patient support, comfort, emotions, physical independence and pain. Each item is rated on a scale of 1 to 5, giving a minimal score of 40 and a maximum score of 200. Higher values represent a better outcome

PRIMARY outcome

Timeframe: Day 1: 24 hours after detubation

Population: Explanation of missing data: One patient from group A missed one page of the QOR-40 questionnaire on postoperative day 1. One patient from group B did not complete the questionnaires on postoperative days 1 and 2 because of personal circumstances
