Comparison of transversus abdominis plane catheters with thoracic epidurals for cost and length of stay in open colorectal surgeries: A cohort study

Thoracic epidural analgesia has long been a common method of postoperative analgesia for major open abdominal surgeries and is frequently used within enhanced recovery after surgery programs. An alternative postoperative analgesia method is the single shot transversus abdominis plane block, which has shown promising outcomes with respect to total length of stay, cost, pain scores, and decreased opioid usage.
