Summary
A new 5-step infiltration technique provides effective local anesthesia for adult groin hernia repair. This method ensures satisfactory anesthesia and prolonged pain relief, using minimal anesthetic solution.
Area of Science:
- Surgery
- Anesthesiology
Background:
- Historically, local anesthesia has been utilized for adult groin hernia repair since Cushing's 1990 recommendation.
- The Lichtenstein Hernia Institute has performed over 12,000 groin hernia repairs under local anesthesia in the past 25 years.
Purpose of the Study:
- To introduce a simplified 5-step infiltration technique for local anesthesia in groin hernia repair.
- To detail a method that achieves satisfactory anesthesia and extended postoperative pain relief.
Main Methods:
- Transition from field block to a simple infiltration technique for local anesthesia over the last 5 years.
- The infiltration technique uses a maximum of 30-40 cc of local anesthetic solution.
- This technique avoids the drawbacks of field block, such as longer procedure times, larger anesthetic volumes, and potential nerve injury.
Main Results:
- The 5-step infiltration technique yields satisfactory local anesthesia.
- It provides prolonged postoperative analgesia.
- The technique requires a reduced volume of local anesthetic solution compared to previous methods.
Conclusions:
- The described 5-step infiltration technique is a safe and effective method for achieving local anesthesia and postoperative pain management in adult groin hernia repair.
- This approach offers advantages over traditional field blocks, including improved patient comfort and reduced risk of nerve-related complications.
