Preemptive morphine suppository for postoperative pain relief after laparoscopic cholecystectomy

Area of Science:

• Anesthesiology
• Surgical Pain Management
• Pharmacology

Background:

• Postoperative pain following laparoscopic cholecystectomy presents a significant clinical challenge.
• Current effective pain relief methods remain a subject of debate.
• Rectal morphine suppositories represent a novel formulation for morphine administration.

Purpose of the Study:

• To evaluate the efficacy of rectal morphine suppositories versus placebo in managing postoperative pain.
• To compare pain intensity and analgesic requirements after laparoscopic cholecystectomy.

Main Methods:

• Seventy patients undergoing elective laparoscopic cholecystectomy were randomized into two groups.
• One group received a 10 mg morphine suppository before anesthesia; the other received a placebo suppository.
• Pain was assessed using the Visual Analog Scale (VAS) and opioid consumption was recorded at multiple time points up to 24 hours postoperatively.

Main Results:

• Patients receiving morphine suppositories reported significantly lower VAS scores from 30 minutes to 16 hours postoperatively compared to the placebo group (P < 0.05).
• The morphine group required no additional analgesia in the first 2 hours post-recovery.
• Significantly fewer patients in the morphine group needed pethidine for pain relief throughout the study period (P < 0.05).

Conclusions:

• Rectal administration of morphine suppositories is an effective strategy for reducing postoperative pain.
• Morphine suppositories significantly decrease the need for additional analgesics after laparoscopic cholecystectomy.
• This intervention offers a promising approach to enhance patient recovery and comfort.
