Control
TAP
Standard analgesic therapy: iv Metamizol 2 g q8h
Transverse abdominal plain (TAP) blockade with local anesthetic: Bupivacaine chlorhydrate 0.25% adjusted by weight and type of surgery. Maximum dose: 150 mg of bupivacaine. Two approaches are done: 1)Posterior TAP: the needle insertion point is cephalad to the iliac crest, behind the midaxillary line. The needle is inserted under ultrasound guidance in plane. Local anesthetics is deposited between the internal oblique and transversus abdominis muscles, 2)Subcostal TAP: the needle is inserted ultrasound guided perpendicularly to abdominal wall, directed parallel to the costal margin but oblique to the sagittal plane. Local anesthestic is deposited between transversus abdominis and the rectus abdominis muscles.
