Interventions

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.

Quadratus Lumborum Block II

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

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 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.

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. 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.

Paravertebral Block
