Clinical Trial Summary

Postoperative pain is important due to the limitation of physical functions, delay in recovery of quality of life, long-term opiate use, length of hospital stay, increased care costs and early postoperative pain trigger chronic pain. It is associated with postoperative morbidity. Multimodal analgesia techniques with fascial plan blocks are frequently used.The investigators aimed to evaluate the effect of QLB2 and ESP on postoperative pain scores in nephrectomy surgery, total opiate consumption, initial analgesia requirement, additional analgesia consumption, patient and surgeon satisfaction.

Description:

At the end of the operation, patients will be randomly divided into 2 groups as Group E (ESP block) and Group Q (QLB). The blocks will be administered under general anesthesia in lateral position by same anesthesiologist. Group E (ESP block) will be applied 20 ml of %0.25 bupivacaine between the erector spina muscle and transverse process at the 8th thoracic level. Group Q (QLB2 block) will be applied 20 ml of %0.25 bupivacaine at lumbar interfacial triangle (LIFT). 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, initial analgesic requirement, nausea-vomiting score, ramsey sedation scale, length of hospital stay, patient and surgeon satisfaction, and postoperative complications will be recorded.
