Comparison of Postoperative Analgesic Efficacy of Transversalis Fascia Plan Block and Erector Spina Plan Block

An identification number (ID) number will be randomly assigned to each patient, whose written consent was obtained before the surgery, when they are admitted to the postoperative recovery room. In the postoperative period, patients will be followed up with these numbers in patient follow-up. Which group the patients will be included in will be determined by the closed envelope method.

The anesthetist, who will perform the regional block, will give the block to be applied in a sealed envelope by an assistant staff outside the study, and at the same time, the patient will not know which block has been made. The anesthesiologist who made the block will not participate in the pain follow-up of the patients. Postoperative pain assessment and data collection will be performed by another investigator blinded to the study.

Spinal anesthesia will be applied to all patients and inguinal hernia operation will be appropriate. Patients taken to the recovery room will be divided into two groups. Transversalis fascia plan block (Group T) will be applied to the patients in a group after local cleansing of the skin area, accompanied by ultrasonography. The patients in the other group will be treated with an erector spina plane block (Group E) following local cleansing of the skin area, accompanied by ultrasonography.

In both block management, 0.25% bupivacaine (Buvasin Vem İlaç, Turkey) (15 ml physiological saline + 15 ml 0.5% bupivacaine) total amount of 30 ml, same volume and same concentration will be used.

After the block procedure, the patient will be observed in the recovery room for side effects. Patient-controlled analgesia (PCA) will be used as a standard in the treatment of postoperative pain in patients in both groups without any complications. Tramadol HCL, which is routinely used for postoperative pain control for PCA, will be used (3 mg/ml, total volume 100 mL).
