Evaluation of Effectivity of Quadratus Lumborum Blocks With Adjuvant

Study Overview
=================
Brief Summary
-----------------
İn recent years abdominal wall blocks are widely used for to reduce intraoperative anesthetic recuirements and postoperative analgesia.Quadratus lumborum blocks are one of the abdominal wall blocks to used at laparoscopic cholecystectomy.Conventionally adjuvants used to improve and prolonged the effect of periferic nerve, spinal and abdominal blocks.İn this study investigators will evaluate the effectiveness of adjuvants at quatratus lumborum block at patient underwent laparoscopic cholecystectomy.

Detailed Description
-----------------
Laparoscopic approach in cholecystectomy surgery is frequently preferred because of its advantages in systemic complications, morbidity, mortality and hospital stay. Pain is one of the important causes of late discharge after surgery. Laparoscopic cholecystectomy surgery requires a multimodal analgesia approach because of its multiple pain components.Regional analgesia techniques are effective in reducing the side effects such as intraoperative opioid use, postoperative pain and nausea and vomiting. Quadratus lumborum III block is a regional technique performed for multimodal analgesia.Adjuvants are known to improve the analgesic efficacy and prolonge the effect of the periferic and central nerve blocks.The aim of this study is to determine the effectiveness of adding adjuvant at quadratus lumborum block for patients who underwent laparoscopic cholecystectomy.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Quadratus lumborum block<br>Patients are placed in the lateral decubitus position. The area where the block will be applied is disinfected with povidine iodine. A convex ultrasound probe is placed on the midaxillary line above the iliac crest. By visualizing the transverse process adjacent to the psoas major and quadratus lumborum muscles, using the in-plane technique, using a 22 gauge 80 mm peripheral block needle after negative aspiration into the anterior layer of the thoracolumbar fascia anterior to the quadratus lumborum muscle muscle, 0.5-1 ml of serum After observing hydrodissection with physiological, 20 ml of 0.25% bupivacaine is injected. The same is done to the opposite side. | Procedure: Quadratus Lumborum Block III<br>* Patients are placed in the lateral decubitus position.
