Diclofenac Premedication, as the Effect of Preemptive Analgesia After Post-thoracotomy Chest and Shoulder Pain

March 8, 2017 updated by: Tamas Vegh, MD, University of Debrecen

Diclofenac Premedication, as the Effect of Preemptive Analgesia After Post-thoracotomy Chest and Shoulder Pain, as Well as the Changes of the Postoperative Breathing Function Values, a Randomized, Controlled, Prospective Trial

The purpose of the study is to examine if the hyposthesis of the preventive analgestic characteristic of diclofenac given preoperatively has any effect on postoperative thoracic wall and shoulder pain sensation. We also want to examine the rescue analgetic consumption and the postoperative lung function test values.

Study Overview

Detailed Description

Introduction Thoracotomies are thought to be one of the most difficult surgical incisions to deal with post-operatively, because they are extremely painful and the pain can prevent the patient from breathing effectively. Currently in our institute the surgical and post-operative anelgesia are managed by the combination of local anesthetics and opioid pain killers through an epidural cannula. In addition the investigators give diclofenac intravenously (from the 2nd day after the operation per os) as well as nalbuphin is given intravenously to the patients if it is necesserary.

By definition pre-emptive analgesia means that the treatment of pain is initiated before the surgical procedure by analgetics or nerve blockade techniques. The purpose of this method is to inhibit the production of inflammatory mediators and the prevention of the pain stimulus entering the central nervous system. As a result of the pre-emptive antinociceptive treatment, the quantity of post-operative medications can be decreased, the analgesia has less complications and the patients are more satisfied.

In the study the researchers would like to examine the pre-emptive analgetic effect of diclofenac.

Patients and methods:

Patients undergoing thoracotomy are divided into two groups.:

  • Study Group: 100mg diclofenac per os (n=50)
  • Control Group: patients do not get diclofenac premedication (n=50) The investigators examine every patient for five days: they record the patients' pain with the help of the Visual Analogue Scale (VAS). We measure the analgetic consumption in intramuscular morphin equivalent dose and the local anesthetic consumption via epidural cannula seperately. The lung function testing was carried out two times postoperatively with the help of the MIR Spirolab II mobil spirometer.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Diclofenac group

Diclofenac 100 mg tablet were administered orally and Midazolam 5 mg + Atropine 0.5 mg were administered intramuscularly as premedication, 60 minutes before surgical interventions.
