Local bupivacaine infiltration did not improve postoperative pain relief for patients undergoing hemorrhoidectomy. This study found no significant difference in pain scores or analgesic needs compared to saline placebo.
Area of Science:
- Anesthesiology
- Colorectal Surgery
Background:
- Hemorrhoidectomy is a common surgical procedure.
- Postoperative pain management is crucial for patient recovery.
Purpose of the Study:
- To evaluate the efficacy of local bupivacaine infiltration for postoperative analgesia after hemorrhoidectomy.
Main Methods:
- 30 patients undergoing Milligan-Morgan hemorrhoidectomy were randomized.
- Groups received either 0.5% bupivacaine or normal saline perianal infiltration.
- Postoperative pain, analgesic use, and recovery metrics were assessed.
Main Results:
- No significant differences were observed in visual analogue pain scores between bupivacaine and saline groups.
- Analgesic requirements, time to first bowel action, and hospital stay duration were similar for both groups.
Conclusions:
- Local infiltration of bupivacaine does not provide significant postoperative analgesia for hemorrhoidectomy patients.
- Further research may explore alternative or multimodal pain management strategies.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
