Pain relief after inguinal hernia repair: a randomized double-blind study

Area of Science:

• Anesthesiology
• Surgical Pain Management
• Pharmacology

Background:

• Postoperative pain management is crucial for patient recovery and satisfaction after hernia repair.
• Optimizing analgesia can facilitate same-day discharge and reduce healthcare costs.

Purpose of the Study:

• To evaluate the efficacy of ilioinguinal field block with bupivacaine combined with oral papaveretum-aspirin for pain relief after hernia surgery.
• To compare this combination therapy against bupivacaine alone, papaveretum-aspirin alone, and placebo.

Main Methods:

• A randomized, double-blind, placebo-controlled study involving 200 male patients undergoing unilateral inguinal hernia repair.
• Four treatment groups received combinations of 0.5% bupivacaine ilioinguinal block and/or oral papaveretum-aspirin or placebo.
• Pain levels and mobility were assessed at 6 and 24 hours post-operation, with on-demand opiate use recorded.

Main Results:

• The combination of bupivacaine and papaveretum-aspirin (Group 1) showed significantly lower pain scores and better mobility compared to placebo (Group 4) and papaveretum-aspirin alone (Group 3).
• Bupivacaine ilioinguinal block alone (Group 2) also provided significant immediate postoperative pain relief compared to placebo (Group 4).
• Group 1 demonstrated the most favorable outcomes in terms of pain reduction and mobility.

Conclusions:

• The combination of bupivacaine ilioinguinal field block and oral papaveretum-aspirin is highly effective for postoperative pain management following hernia surgery.
• This combined analgesic strategy is suitable for optimizing recovery in day-case surgery settings.
