Clinical Trial Summary

This trial is a prospective, randomized, single-center, single blinded-analysis trial, the objective of which is compare the postoperative analgesia efficacy of Quadratus lumborum II, Quadratus Lumborum III and Paravertebral blocks in elective laparoscopic cholecystectomy.

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 block and paravertebral plane blocks are regional techniques performed for multimodal analgesia. The aim of this study is to determine an effective analgesia method by comparing the postoperative analgesic effectiveness of Quadratus Lumborum II, Quadratus Lumborum III and Paravertebral blocks in elective laparoscopic cholecystectomy surgery.

Intervention

Procedure:
• Quadratus Lumborum Block II
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 psoas major and the transverse process adjacent to the quadratus lumborum muscle, using the in-plane technique, using a 22 gauge 80 mm peripheral block needle negative aspiration into the middle layer of the thoracolumbar fascia posterior to the quadratus lumborum muscle, then 0.5-1 ml of saline 20 ml of 0.25% bupivacaine will be injected after hydrodissection is observed. The same will be done to the other side.

Drug:
• Patient controlled intravenous analgesia
Afterward of the operation, patients will be treated with patient-controlled analgesia with intravenous tramadol, with 20 mg bolus 20 minutes lock time, 4-hour limit 100 mg and 24-hour limit 400 mg

Procedure:
• Quadratus Lumborum Block III
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.

Drug:
• Patient controlled intravenous analgesia
Afterward of the operation, patients will be treated with patient-controlled analgesia with intravenous tramadol, with 20 mg bolus 20 minutes lock time, 4-hour limit 100 mg and 24-hour limit 400 mg

Procedure:
• Paravertebral Block
Patients are placed in the lateral decubitus position. The area where the block will be applied is disinfected with povidine iodine. The linear ultrasound probe is placed longitudinally at the T6 level, 2-2.5 cm lateral to the spinous processes. Transverse process, superior costotransverse ligament and pleura are visualized, 22 gauge 80 mm peripheral block needle is passed with in-plane technique, superior costotransverse ligament is passed, negative aspiration into the paravertebral space under the ligament, followed by 0.5-1 ml of saline and hydrodissection of the pleura, followed by 20 ml of 0.25% bupivacaine is injected.The same is done to the opposite side.

Drug:
• Patient controlled intravenous analgesia
Afterward of the operation, patients will be treated with patient-controlled analgesia with intravenous tramadol, with 20 mg bolus 20 minutes lock time, 4-hour limit 100 mg and 24-hour limit 400 mg

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Total amount of tramadol use	The total tramadol use of the patients in 24 hours will be recorded.	within 24 hours after the surgery
Secondary	Visual Analogue Scale values at 1st, 6th, 12th and 24th hours	Visual Analogue Scale is a scale of 0-10 cm in length, expressed by non-standard verbal descriptors (no pain-unbearable pain..) indicating the limits of pain intensity on both sides, horizontally or vertically.	at 1st, 6th, 12th and 24th hours after the surgery
Secondary	Block onset time	In order to evaluate sensory block, dermatome involvement will be evaluated with ice between Thoracic 1 and Lumbar 5 levels. When the feeling of coldness disappears, dermatome involvement will be considered. The sensory block formation time with ice will be evaluated as the block onset time, the10th, 20th and 30th minute dermatome area involvement will be recorded.	30 min after the block
Secondary	intraoperative remifentanil consumption	The total remifentanil use to be used in the maintenance of 0.05-0.2 mcg/kg remifentanil will be recorded by titration according to the hemodynamic data of the intraoperative patients.	during operation procedure
Secondary	postoperative length of hospital stay	time to patient's discharge	within 1 weeks after the surgery
Secondary	side effects such as nausea, vomiting and shoulder pain	The incidence of postoperative side effects such as nausea, vomiting and shoulder pain will be evaluated.	within 24 hours after the surgery
