Erector Spine Block
After induction of general anesthesia, external oblique intercostal blocks will be performed with patients positioned in the supine position with their ipsilateral arm abducted. A 14-15 MHz linear ultrasound transducer (Sono-Site) was placed in the sagittal plane between the midclavicular and anterior axillary lines at the level of sixth rib. 30 ml of bupivacaine 0.25% will be administered incrementally. The drug will be injected after a negative aspiration into the plane deep to the external oblique muscle and superficial to the sixth and seventh ribs and their associated intercostal muscles.
After induction of general anesthesia, patients will be positioned in the lateral position . A linear ultrasound transducer will be placed on the midline to identify the T8 spinous process. From this position, the ultrasound transducer was moved 2-3 cm laterally to visualize the hyperechoic line of the T8 transverse process with its associated acoustic shadow inferiorly, and the overlying erector spinae muscle superiorly. 30 ml 0.25% bupivacaine will be injected.
