Perioperative Dexamethasone Reduces Postoperative Pain and Nausea After Hip Arthroscopy

Perioperative Dexamethasone Reduces Postoperative Pain and Nausea After Hip Arthroscopy- a Double-blinded Placebo Controlled RCT

The purpose of this study is to assess the effect of Dexamethasone on postoperative pain and nausea after hip arthroscopy.

Study Overview

• Status: Completed
• Conditions: Pain, Postoperative; Opioid Use; Nausea, Postoperative
• Intervention / Treatment: Drug: NaCl 0.9%; Drug: Dexamethasone 4mg

Detailed Description

Hip arthroscopy (HAS) is a standard procedure with good mid and long-term results. Postoperative pain is a great concern and postoperative pain management of great importance. High demand for opiates and the associated side effects especially nausea limit the postoperative rehabilitation.

Promising results to reduce postoperative pain and nausea have been achieved by perioperative dexamethasone, which has a strong anti-inflammatory effect reducing pain and inflammation as well as a strong anti-emetic effect, especially in total hip replacement.

It is our goal to compare the effect of perioperative intravenous dexamethasone (3x 4mg Amp. Fortecortin =12mg prior to surgery and 3x4mg Amp. Fortecortin = 12mg at 8.00am of the first postoperative day in 250ml saline solution) to a control group (placebo) (1x 250ml saline solution postoperative day 1 at 8.00am) regarding pain level, opiate consumption, postoperative nausea and patient satisfaction.

A double-blinded prospective randomized control trial including 60 patients receiving elective unilateral HAS will be conducted.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Dexamethasone group; The patients in the dexamethasone group will receive 12mg dexamethasone (Fortecortin ®) intravenously 15-60 minutes prior to surgery while in general anasthesia as well as 12mg dexamethasone intravenously (Fortecortin®) on the first postoperative day at approx. 8.00a.m. by the investigators.	Drug: Dexamethasone 4mg; s. arm/group description; Other Names: Fortecortin Inject (Merck (Switzerland))
Placebo Comparator: Placebo/ Control group; The patients will not receive any additional drugs preoperatively. A 0.9% NaCl Solution (NaCl B. Braun Inf Lös 0.9 % 250ml Ecoflac plus®) will be administered at approx. 8.00 a.m. on the first postoperative day by the investigators.	Drug: NaCl 0.9%; s. arm/group description; Other Names: NaCL Braun (B.Braun Medical)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postoperative pain level	The VAS Pain score assesses pain Levels on a scale from 0 (no pain) to 10 (wost possible pain).	6 hours postoperatively
