Transversus Abdominus Plane Block
Ultrasound Guided Transversus Abdominus Plane Block for Patients Undergoing Laparoscopic Hand-assisted Nephrectomy.
Transversus Abdominus Plane (TAP) block may reduce need for postoperative pain medications in patients undergoing laparoscopic hand assisted nephrectomy. Our hypothesis is that the TAP block will result in a significant reduction in pain scores and morphine requirements in the active group.
