Serratus Anterior Block and Erector Spinae Block in Postoperative Analgesia

Evaluation of the Effect of Serratus Anterior Block and Erector Spinae Block on Postoperative Analgesia in Thoracic Surgeries

90 patients scheduled for thoracic cancer surgeries, allocated in 3 groups for serratus anterior block and erector spinae block and control group. during anaesthesia:total intraoperative fentanyl required will be recorded. After surgery, all patients will be connected to PCA device containing morphine solution, the amount of morphine consumed during the first 24 hours will be recorded.

90 patients scheduled for thoracic cancer surgeries, allocated in 3 groups for serratus anterior block (SAB) and erector spinae block (ESB) and control group. During anaesthesia: total intraoperative fentanyl required will be recorded. After surgery, all patients will be connected to PCA device containing morphine solution, the amount of morphine consumed during the first 24 hours will be recorded. Other secondary outcomes are: numerical rating scales and postoperative pulmonary functions.
