Evaluation of Effectivity of Quadratus Lumborum Blocks With Adjuvant

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.

Conditions

Interventions

PROCEDURE

Adjuvant-free Quadratus lumborum block

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 with Adjuvant

The same block was applied to this group too, but a different local anesthetic mixture was used.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 and 4mg dexamethasone is injected. The same is done to the opposite side.
