Comparison of Two Regional Blocks For Pain Treatment After Laparoscopic Cholecystectomy

: It was performed under USG guidance using 30 ml of 0.25% bupivacaine with an 80 mm insulated peripheral block needle. Local anaesthetic was applied between the upper fascia of the transversus abdominus muscle and the fascia of the internal oblique muscle at the midpoint of the distance between the costal margin and the iliac crest in the midaxillary line under USG imaging guidance.

Under USG guidance, 20 ml of 0.25% bupivacaine was administered between the upper fascia of the transversus abdominis muscle and the lower fascia of the costochondral tissue at the level of the 9th and 10th ribs (arcus costarum) in the midclavicular line with an 80 mm insulated peripheral block needle. Then, 10 ml of 0.25% bupivacaine was injected into the upper fascia of the costochondral tissue and the lower fascia of the external oblique muscle. The block was performed by following the needle path in the ultrasound image.
