Deep Versus Moderate Muscle Relaxation During Laparoscopic Donor Nephrectomy in Enhancing Postoperative Recovery (RELAX)

August 16, 2019 updated by: Radboud University Medical Center

The Effectiveness of Deep Versus Moderate Muscle Relaxation During Laparoscopic Donor Nephrectomy in Enhancing Postoperative Recovery

Postoperative recovery after live donor nephrectomy (LDN) is largely determined by the consequences of postoperative pain and analgesia consumptions. The investigators' goal is to establish the relationship between the use of deep neuromuscular blockade (NMB) during laparoscopic donor nephrectomy (LDN) and the early quality of recovery. Therefore, the investigators designed a trial in which patients scheduled for living donor nephrectomy are randomized into a group with deep NMB or moderate NMB. The primary outcome measurement will be the Quality of Recovery-40 questionnaire (overall score) at 48 hours after extubation.

Study Overview

Detailed Description

Rationale: Postoperative recovery after live donor nephrectomy (LDN) is largely determined by the consequences of postoperative pain and analgesia consumptions. The use of deep neuromuscular blockade (NMB) has shown to reduce postoperative pain scores after laparoscopic surgery. With this study the investigators will investigate if deep NMB also improves the early quality of recovery after LDN.

Objective: To establish the relationship between the use of deep neuromuscular blockade (NMB) during laparoscopic donor nephrectomy (LDN) - with standard pressure pneumoperitoneum - and the early quality of recovery.

Study design: A multicenter, blinded, randomized controlled trial

Study population: 96 adult patients (18 years or older), scheduled for living donor nephrectomy, will be randomized into a group with deep or moderate neuromuscular blockade. Deep neuromuscular blockade is defined as post tetanic count 1-2.

Main study parameters/endpoints: The primary outcome measurement will be the Quality of Recovery-40 questionnaire (overall score) at 48 hours after extubation.

Secondary outcomes measured are: intra-operative parameters (e.g. surgical conditions, operation time, length of pneumoperitoneum, first warm ischemia time, estimated blood loss, conversion to open or hand-assisted donor nephrectomy, intra-operative complications, cumulative use of rocuronium and sugammadex), the total score of the quality of Recovery-40 questionnaire at 48 hours after extubation, post-operative pain (components of pain scores); postoperative nausea and vomiting (NRS), the cumulative use of analgesics and anti-emetics, time to reach discharge criteria and postoperative complications.

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Quadruple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A: Deep Neuromuscular blockade
An extra bolus of rocuronium after intubation followed by infusion
A bolus of 0.7 mg/kg rocuronium is administered just after tracheal intubation and then an infusion of rocuronium (0.3 to 0.4 mg/kg) is started when post-tetanic count (PTC) is more than 0 and titrated towards PTC 1-2.
Sham Comparator: Group B: Moderate neuromuscular Blockade
Moderate neuromuscular Blockade No additional rocuronium after intubation.
No additional rocuronium is administered after tracheal intubation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Total Score of the Quality of Recovery-40 Questionnaire (QoR-40)
Time Frame: Day 1: 24 hours after detubation
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
Day 1: 24 hours after detubation
