This study compares efficacy of transversus abdominis plane block and ilioinguinal nerve block for postoperative pain in patients undergoing inguinal herniorraphy with spinal anesthesia. One-third of the patients will receive standard postoperative pain regimen(control group), one-third will receive a transversus abdominis plane block (with ultrasound guidance) and the last group will receive an ilioinguinal nerve block(with ultrasound guidance) in addition to standard postoperative pain regimen. This study is a Randomized prospective open-label controlled study.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intrathecal bupivacaine&analgesics | Active Comparator | Patients will be given standard care during perioperative period. They will undergo inguinal herniorraphy operation under spinal anesthesia (with 3ml of %0.5 hyperbaric bupivacaine intrathecally) and receive an parenteral pain regimen (acetaminophen for intravenous infusion in two doses routinely and intramuscular tramadol 50 mg when pain score is higher than 4) in postoperative period. |
|
| TAP Block with bupivacaine | Experimental | In addition to standard perioperative care (spinal anesthesia and parenteral pain regimen) patients will receive transversus abdominis plane block (with 20ml of %0.25 isobaric bupivacaine) just before surgery is initiated. |
|
| IlNB with bupivacaine | Experimental | In addition to standard perioperative care (spinal anesthesia and parenteral pain regimen) patients will receive Ilioinguinal nerve block (with 20ml of %0.25 isobaric bupivacaine) just before surgery is initiated. |

|
|
| Ilioinguinal Nerve Block | Procedure | Analgesic intervention which will be performed only to Ilioinguinal Nerve Block arm.
