Summary

Subcutaneous morphine bolus injections effectively manage postoperative pain after major abdominal surgery. Subcutaneous infusions, however, are less practical due to equipment limitations.

Area of Science:

  • Anesthesiology
  • Pain Management
  • Surgical Care

Background:

  • Postoperative pain management is crucial for patient recovery.
  • Subcutaneous morphine is a common analgesic option.
  • Evaluating delivery methods for subcutaneous morphine is important for clinical practice.

Purpose of the Study:

  • To compare the efficacy of subcutaneous morphine infusion versus bolus injections for postoperative analgesia.
  • To assess the suitability of a simple micro-infusion set for subcutaneous morphine delivery.

Main Methods:

  • A double-blind, prospective, controlled clinical trial involving 21 patients (ASA classes I-II) undergoing major elective abdominal surgery.
  • Patients received intravenous loading doses of morphine followed by either subcutaneous infusion (using a power-driven pump or micro-infusion set) or three-hourly subcutaneous bolus injections.
  • Pain was assessed hourly using a modified verbal rating scale, and the need for intravenous supplements was recorded.

Main Results:

  • Subcutaneous morphine infusion provided adequate analgesia in 86% of patients.
  • No significant difference in the requirement for additional intravenous supplements was observed between the groups.
  • The micro-infusion set necessitated frequent adjustments to maintain a consistent flow rate.

Conclusions:

  • Intermittent subcutaneous bolus injections of morphine are a simple, safe, and effective method for postoperative analgesia.
  • Simple infusion sets are not ideal for subcutaneous infusions, and the reliance on infusion pumps makes this technique less suitable for routine ward use.
