Comparison of Postoperative Analgesic Efficacy of Transversalis Fascia Plan Block and Erector Spina Plan Block
Condition: Regional Anesthesia
Study type: Interventional

Summary: 
      The subject of the study is to compare the analgesic efficacy of transversalis fascia plan
      block and erector spina plane block applied with ultrasonography in patients who have
      undergone inguinal hernia operation. The aim of the study is to compare two different
      regional anesthesia methods applied in the postoperative period in terms of 24-hour opioid
      consumption, pain scores, additional analgesic need, and side effects and complications in
      the postoperative period.
    

Detailed description: 
      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).

      Evaluation of postoperative pain will be done with numerical rating scale (NRS).Pain levels
      will be questioned in two different ways as rest and cough.
