Summary
Penile block (PB) techniques for adult circumcision were compared. Subcutaneous ring block and combined dorsal nerve block with frenulum infiltration offer effective anesthesia with fewer failures and good pain relief.
Area of Science:
- Anesthesiology
- Urology
Background:
- Penile block (PB) is an underutilized anesthetic technique in adults.
- Effective anesthesia is crucial for adult circumcision procedures.
Purpose of the Study:
- To compare the efficacy and safety of five distinct penile block techniques.
- Evaluate anesthetic quality, complication rates, and postoperative analgesia in adults undergoing circumcision.
Main Methods:
- A randomized prospective study involving 250 adult patients undergoing circumcision.
- Patients were divided into five groups (50 each) receiving different PB techniques: "10, 30-13, 30" approach, subpubic approach, subcutaneous ring block, and two combination approaches.
Main Results:
- Groups using the "10, 30-13, 30" and subpubic approaches had significantly higher block failure rates (41% and 43%) compared to subcutaneous ring block and combination techniques (2-5%).
- No significant differences in adverse effects or time to postoperative pain onset were observed among successful blocks across the five groups.
Conclusions:
- Subcutaneous ring block and combined dorsal nerve block with frenulum infiltration are effective penile block techniques for adult circumcision.
- These methods provide good surgical anesthesia, low complication rates, and prolonged postoperative analgesia.
