ISRCTN - ISRCTN48329522: Perioperative Duloxetine and Etoricoxib improve postoperative pain

Plain English Summary

Background and study aims
Having spinal surgery requires a lot of recovery time. Usually patients who undergo surgery need medication to help them recover and control any after surgery pain. There are a variety of medications that can be used to help treat patients. Some suggestions for medications to use include duloxetine (which is used to treat anxiety, depression, neurological pain) as well as etoricoxib (an anti-inflammatory (swelling) painkiller). It can be sometimes difficult for healthcare workers to figure out what the best combination of medications is most effective and provides patients with the least amount of side effects while still improving their pain symptoms. The aim of this study is to find the best regimen of drugs for the postoperative (after surgery) analgesia (pain prevention) for patients undergoing spinal surgeries in order to improve patient satisfaction of their postoperative care and to provide them with less side effects from medication after the surgery.

Who can participate?
Adults patients aged 18 and older who are having spinal surgery.

What does the study involve?
Participants are randomly allocated to one of four groups. Those in the first group receive a capsule containing a placebo (dummy drug) and two placebo tablets an hour before surgery and then again 24 hours later. Those in the second group receive a capsule a placebo and two etoricoxib tablets an hour before surgery and then again 24 hours later. Those in the first group receive a capsule containing duloxetine and two placebo tablets an hour before surgery and then again 24 hours later. Those in the fourth group receive a capsule containing duloxetine and two etoricoxib tablets an hour before surgery and then again 24 hours later. Patients then have their surgery as per standard practice. Half an hour after their anaesthesia has worn off and then two, four, six, 12, 24 and 48 hours later, participants are asked to rate their pain levels. Their satisfaction with the treatment they received and pain killer use is also recorded.

What are the possible benefits and risks of participating?
Participants may benefit from being more satisfied with their surgery and less side effects from drugs after the surgery. There are no notable risks with participating however there are risks with any medication and this should be monitored.

Where is the study run from?
Minia University Hospital (Egypt)

Condition

Postoperative pain after laminectomy surguries

Intervention

Patients admitted to the hospital are randomised using computer-generated random numbers with closed-sealed envelopes into one of the four groups of 30 patients.

Group 1: Participants receive a placebo capsule + two placebo tablets one hour before surgery and again 24 hours later
Group 2: Participants receive a placebo capsule + 90 mg etoricoxib tablets one hour before surgery and again 24 hours later
Group 3: Participants receive a 60 mg duloxetine capsule + two placebo tablets one hour before surgery and again 24 hours later
Group 4: Participants receive a 60 mg duloxetine capsule + two 90 mg etoricoxib tablets one hour before surgery and again 24 hours later

Participants in all groups undergo surgery as per standard practice.

Participants in all groups are asked to rate their pain levels 30 minutes after the end of anesthesia and two, four, six, 12, 24 and 48 hours post-operatively. In addition, patient satisfaction and pain killer use is also assessed 24 and 48 hours after surgery.

Primary outcome measures

Pain is measured using pain assessment measures and questions 30 minutes after the end of anesthesia and two, four, six, 12, 24 and 48 hours post-operatively

Secondary outcome measures

1. The time to first rescue analgesic is routinely 24h and 48h postoperatively
2. Total morphine consumption is measured by calculating the doses at 24 and 48 hours post-operatively
3. Side effects, including headache, rash, nausea, vomiting, dizziness and drowsiness are recorded. The severity of postoperative nausea and vomiting (PONV) is graded on a four-point ordinal scale
4. Patient satisfaction is measured using a numerical rating scale (NRS) at 24 hours post-operatively
