Evaluation of Effectivity of Erector Spina Plane Block With Different Levels

Summary

In last years, erector spinae plane block is widely used in abdominal and thoracic surgeries. Laparoscopic cholecystectomy is one of the most commonly performed surgical operations. In this study, the investigators will evaluate the effectiveness of erector spina plan block with different injection levels for postoperative analgesia on patients undergoing laparoscopic cholecystectomy surgery.

Conditions

• Postoperative Pain

Interventions

PROCEDURE

T7 Level Erector Spinae Plane Block

ESP block is planned after the completion of surgery and before the extubation. Its application will be planned from the T7 level bilaterally when the patients are turned to the right lateral position. A linear ultrasound probe will be placed in the longitudinal parasagittal orientation 3 cm to lateral of T7 spinous process. After imaging of erector spina musceles and transvers process of 7 th trorocal vertebrae, an ultrasound-guided local anaesthetic mixture ( 0.5% bupivacaine 15 cc + 2% lidocaine 5 cc) will be applied to the region between spinae muscles and transverse process using a needle of 22 gauge \& 8cm directed from cranial to caudal. After application of the same procedure to the other side, the patients will be woken-up and patient-controlled analgesia consisting of intravenous morphine will be planned for all of them. Additionally, at postoperative 1.,4.,8.,12.,24. hours, NRS scales and morphine consumption will be recorded.

PROCEDURE

T9 Level Erector Spinae Plane Block

ESP block is planned after the completion of surgery and before the extubation. Its application will be planned from the T9 level bilaterally when the patients are turned to the right lateral position. A linear ultrasound probe will be placed in the longitudinal parasagittal orientation 3 cm to lateral of T9 spinous process. After imaging of erector spina musceles and transvers process of 9 th trorocal vertebrae, an ultrasound-guided local anaesthetic mixture ( 0.5% bupivacaine 15 cc + 2% lidocaine 5 cc) will be applied to the region between spinae muscles and transverse process using a needle of 22 gauge \& 8cm directed from cranial to caudal. After application of the same procedure to the other side, the patients will be woken-up and patient-controlled analgesia consisting of intravenous morphine will be planned for all of them. Additionally, at postoperative 1.,4.,8.,12.,24. hours, NRS scales and morphine consumption will be recorded.

DRUG

control group

24 hours morphine consumption will be recorded using the patient controlled analgesia device with intravenous morphine.
