QIPB in Inguinal Hernia

Condition(s) studied

Investigational drug(s) / intervention(s)

Quadro iliac plane block: Patients in Group Q will be placed in the lateral position. A low-frequency convex transducer and a 100-mm block needle will be used. Following sterilization, the transducer will be placed parasagittally at the distal attachment of the quadratus lumborum muscle to the iliac crest. The iliac crest and quadratus lumborum muscle will be visualized, with the erector spinae muscle above and the psoas major muscle below. Using an in-plane technique, the needle will be directed toward the iliac crest. After confirmation with 5 mL of isotonic sodium chloride, 20 mL of 0.25% bupivacaine will be injected incrementally with intermittent aspiration. The same procedure will be applied to the other party. A total of 40 mL of 0.25% bupivacaine will be administered.

Control group: All patients will receive IV paracetamol (1 g, 3×1) and IV tenoxicam (20 mg, 2×1).

Study summary

Inguinal hernia repair is one of the most commonly performed surgical procedures. It is generally performed under regional anesthesia techniques, such as local anesthesia, peripheral nerve blocks, or neuraxial anesthesia (spinal or epidural anesthesia), or under general anesthesia. Despite various available analgesic regimens, numerous studies have demonstrated that postoperative pain control remains inadequate. Opioids, nonsteroidal anti-inflammatory drugs, and analgesics are frequently used for postoperative pain management. However, these medications are associated with uncertain efficacy and undesirable side effects. Pain is a critical factor in the postoperative period, contributing to delayed ambulation and paralytic ileus, ultimately hindering early discharge.
