[A concept for decreasing postoperative pain after inguinal hernia operation]

Area of Science:

• Surgical innovation
• Pain management
• Anesthesiology

Background:

• Inguinal hernia repair is a common procedure, with approximately 150,000 performed annually in Germany.
• Effective pain management during and after surgery is crucial for patient recovery and satisfaction.
• Optimizing surgical techniques must include comprehensive pain control strategies.

Purpose of the Study:

• To evaluate the efficacy of intraoperative anesthesia using a long-acting local anesthetic and vasoconstrictor for ilioinguinal and iliohypogastric nerve blocks.
• To compare post-operative pain levels in patients receiving this nerve block versus a control group.
• To determine if intraoperative anesthesia can provide sustained pain relief after inguinal hernia surgery.

Main Methods:

• A prospective, randomized, double-blind study was conducted.
• Patients undergoing herniotomy received either intraoperative anesthesia with a specific local anesthetic combination or a placebo (control group).
• Pain was assessed using a 1-10 scoring scale on the day of surgery and subsequently.

Main Results:

• Intraoperative anesthesia demonstrated a significant reduction in post-operative pain scores.
• Pain reduction was observed both on the day of the operation and in the period following the anesthetic's decreased effect.
• The intervention group reported lower pain levels compared to the control group.

Conclusions:

• Intraoperative anesthesia, particularly with local anesthetics, is an effective strategy for managing post-herniotomy pain.
• Initiating pain therapy during surgery is optimal for sustained relief.
• This method avoids systemic analgesic side effects and can reduce risks associated with ambulatory hernia surgery.
