Intervention model description: Group I: TAP block with bupivacain and morphine intramuscular will be applied at the end of the operation. Patients will receive paracetamol 1gr 30 minutes before the end of the operation. All patients will undergo IV morphine patient-controlled analgesia (PCA). Pain, opioid consumption, hemodynamic parameters and complications will be monitored in the first 24 hours in the postoperative period.

Group T: TAP block with bupivacain and morphine will be applied at the end of the operation. Patients will receive paracetamol 1gr 30 minutes before the end of the operation. All patients will undergo IV morphine patient-controlled analgesia (PCA). Pain, opioid consumption, hemodynamic parameters and complications will be monitored in the first 24 hours in the postoperative period.
Primary purpose: OTHER

Brief summary: Postoperative pain is a condition that increases morbidity and mortality. Therefore, multimodal analgesia techniques with fascial plan blocks are frequently used.TAP block provides analgesia in the anterior abdominal wall by applying local anesthetic to the fascia between the internal oblique and transversus abdominis muscle. Opioids can be added to local anesthetics to increase the quality and duration of analgesia. The investigators aim is comparasion of TAP block with bupivacaine added morphine and TAP block with bupivacaine plus intramuscular morphine effects on postoperative pain score, total opioid consumption and systemic effects in lower abdominal surgery

Detailed description: At the end of the operation, patients will be randomly divided into 2 groups as Group I (Intramuskuler) and Group T (TAP block). The blocks will be administered under general anesthesia in supine position by same anesthesiologist. Group I (Intramuskuler) will be applied 20 ml of %0.25 bupivacaine between the internal oblique and transversus abdominis muscle and 0.1 mg/kg (ideal body weight) morphine to be performed intramuscular. Group T will be applied 20 ml of %0.25 bupivacaine and 0.1 mg/kg morphine (ideal body weight) between the internal oblique and transversus abdominis muscle. At the end of the operation, the patients with a Modified aldreate score ≥9 will be sent from the postoperative anesthesia unit. All patients will be equipped with an IV morphine patient-controlled analgesia (PCA) device. The solution will be prepared such that morphine is 0.5 mg / ml. PCA 1mg bolus dose will be delivered with 10 min lock-out time. In the postoperative period, the patient was evaluated by another researcher who blind to the groups at the 1st and 6th, 12th and 24th hours. Visual pain scores (VAS) in rest and movement, hemodynamic values, morphine consumption, nausea-vomiting score, itching, ramsey sedation scale, length of hospital stay and postoperative complications will be recorded.
