Summary
Preincisional bupivacaine hydrochloride infiltration before tonsillectomy significantly reduced postoperative pain scores. However, it did not decrease analgesic intake, suggesting insufficient pain management in the initial postoperative days.
Area of Science:
- Anesthesiology
- Otolaryngology
- Pain Management
Background:
- Tonsillectomy is a common surgical procedure associated with significant postoperative pain.
- Effective pain management is crucial for patient recovery and satisfaction after tonsillectomy.
Purpose of the Study:
- To evaluate the efficacy of preincisional peritonsillar infiltration of bupivacaine hydrochloride in reducing postoperative pain following tonsillectomy under general anesthesia.
Main Methods:
- A double-blind, placebo-controlled trial was conducted with 19 adult patients undergoing tonsillectomy.
- Patients received either 0.25% bupivacaine hydrochloride or normal saline infiltration around the tonsils.
- Postoperative pain was assessed using a visual analogue scale, and analgesic intake was recorded for 10 days.
Main Results:
- The bupivacaine group reported significantly lower visual analogue scale pain scores compared to the placebo group.
- No significant difference in daily analgesic intake was observed between the two groups.
Conclusions:
- Preincisional peritonsillar bupivacaine infiltration effectively reduces prolonged postoperative pain after tonsillectomy.
- Current analgesic regimens may be insufficient for optimal pain control in the immediate postoperative period.
