Study Summary

The purpose of this study is to investigate the analgesic efficacy of an ultrasound-guided inguinal field block (block of the genitofemoral, iliohypogastric and ilioinguinal nerve).

Study Description

Inguinal hernia repair accounts for 10-15% of all operations in general surgery. Moderate to severe pain can occur at the first day after inguinal hernia repair in 25% of patients at rest and in 60% during activity. On day 6 after the operation the incidence can be as high as 11% at rest and 33% during activity.

Ultrasound imaging for regional anesthesia techniques have improved the success and safety rate of nerve blocks. We hypothesized that a procedure consisting of an ultrasound-guided inguinal field block (genitofemoral, iliohypogastric and ilioinguinal nerve block and incision line infiltration) could effectively control postoperative pain compared to selective unilateral subarachnoid anesthesia.
