Patient Re-education vs. Background Morphine to IV-PCA in Patient With Unsatisfactory Analgesia Post Laparotomy

Post-operative Pain Clinical Trial

Official title:
Comparing Effectiveness of Post-operative Analgesia Between Patient Re-education and the Additional of a Basal Morphine Infusion to IV-PCA Morphine in Patients With Unsatisfactory Analgesia After Laparotomy

Clinical Trial Summary

The purpose of this study is to improve IV-Patient Controlled Analgesia (IV-PCA) technique for postoperative analgesia. Investigators are comparing between patient re-education and the background morphine infusion among patients who fail to achieve satisfactory analgesia using IV-PCA Morphine after laparotomy.

Clinical Trial Description

In this study, investigators have a second inclusion criteria for subject recruitment. For subjects who meet this criteria meaning their dynamic pain (when blowing incentive spirometer) is ≥ 4/10 after starting on IV-PCA Morphine will be randomized in to 2 groups. One group will receive patient re-‐education with an additional background morphine infusion and the other group will receive re-‐education only.

The second highlight for this study is regarding the background morphine calculation. The background morphine is calculated according to this formula:

Total morphine requirement in the first 24 hours post surgery (mg) = 100 - Age (year) So, the background morphine infusion will be calculated based on subject's age and half of their 24 hours requirement will be infused over 24 hours.

This formula was published by Pamela Macintyre in her paper titled " Age is the Best Predictor of Postoperative Morphine Requirement". ;
