Summary
Local anesthetic infiltration before surgery significantly reduces tonsillectomy pain. This study confirmed that bupivacaine hydrochloride infiltration effectively alleviates postoperative pain beyond the initial recovery period.
Area of Science:
- Anesthesiology
- Surgical Pain Management
Background:
- Local anesthetic infiltration is a known method to reduce postoperative pain.
- Its efficacy in tonsillectomy under general anesthesia requires further investigation.
Purpose of the Study:
- To evaluate the effectiveness of preincisional local anesthetic infiltration in managing postoperative pain following elective tonsillectomy.
Main Methods:
- A double-blind, randomized study involving 129 patients undergoing elective tonsillectomy.
- Standard surgical technique with preoperative peritonsillar area infiltration using bupivacaine hydrochloride.
Main Results:
- Preincisional infiltration with bupivacaine hydrochloride significantly decreased pain intensity after tonsillectomy.
- The pain reduction extended well beyond the immediate postoperative phase.
Conclusions:
- Preoperative local anesthetic infiltration is an effective strategy for managing tonsillectomy-related postoperative pain.
- Bupivacaine hydrochloride provides prolonged pain relief, improving patient recovery.
