Bilateral vs. Unilateral Erector Spinae Plane Block

Bilateral vs. Unilateral Erector Spinae Plane Block for Laparoscopic Cholecystectomy; A Randomised Controlled Trial

The importance of multimodal analgesia for postoperative pain management is well known and regional anesthesia techniques are commonly prefferred to provide better analgesia. Erector spinae plane block (ESB) is a new defined and effective regional anesthesia technique. But two injections can be unconfortable for some patients. With this study, we aimed to compare the analgesia effect of bilateral and unilateral ESP block for laparoscopic cholecystectomy.

Inclusion Criteria:

• ASA I-II patients

Exclusion Criteria:
