Pain Interventions For Organ Transplant Patients Undergoing Incisional Hernia Repair - Is Epidural or Transversus Abdominus Plane Block A Better Option?

Background Postoperative pain management in transplant recipients undergoing incisional herniorraphy is challenging. Historically limited to intravenous or oral opioids, alternatives including transversus abdominus plane (TAP) block catheters and thoracic epidural catheters have been introduced. The aim of this study was to determine whether TAP catheters and thoracic epidural analgesia significantly impacted on postoperative pain and opioid usage in transplant recipients undergoing incisional hernia repair. MethodsResultsThis single-center retrospective study included 154 patients undergoing incisional hernia repair from January 2011 to June 2015. Of these, 56 received epidurals, 51 received TAP catheters, and 47 received no intervention. Demographic profiles were comparable among the three groups including type of previous transplant and type of hernia surgery. Thoracic epidural analgesia was associated with lower median, mean, and maximum pain scores (P<0.001) and less opioid requirement (P<0.001). There was no difference in pain scores and opioid usage among the TAP catheter and no intervention groups. There was no difference in time to first flatus or first bowel movement, length of hospital stay, individual opioid-related side effects, and adverse reactions among the three groups. ConclusionThis study supports the use of thoracic epidural analgesia in patients undergoing hernia repair after transplant surgery.
