Oblique sub-costal transversus abdominis plane (TAP) catheters: an alternative to epidural analgesia after upper abdominal surgery.

Abstract

The authors present three cases where catheters placed in the oblique sub-costal transversus abdominis plane provided prolonged analgesia after upper abdominal surgery. Patient 1 was admitted with severe sepsis following major hepatobiliary surgery. Bilateral catheters facilitated weaning from mechanical ventilation and provided adequate analgesia for 4 days. Patient 2 underwent emergency laparotomy for intestinal obstruction having refused consent for epidural analgesia. The transversus abdominis plane catheters provided a significant opioid sparing effect. A unilateral catheter offered rescue analgesia in patient 3 when the epidural catheter was displaced. We put forward a case for oblique sub-costal transversus abdominis plane catheters as an alternative to epidural analgesia after upper abdominal surgery.
