Subcostal transversus abdominis plane (TAP) block may be of interest in this population. The aim of this study was to evaluate the impact of subcostal TAP block on opioid consumption after liver transplantation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We conducted a before-and-after single center study. During the first period, we included patients whom did not receive an analgesic TAP block. During the second period, we included those with bilateral ultrasound-guided subcostal TAP block (20\u2009mL ropivaca\u00efne 0.2% each side). Patients requiring sedation within 48 hours of surgery as well as patients with combined liver and kidney transplants or skin-only closures were excluded. The primary outcome was cumulative oral morphine consumption within 48 hours after surgery. Secondary outcomes included pain scores and TAP block-related complications.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>A total of 132\u2009patients were included in the non-TAP block group and 78\u2009patients in the TAP block group. The median oral morphine equivalent consumption (IQR) within 48 hours following surgery was 74\u2009mg (39; 112) for the non-TAP block group and 50\u2009mg (20; 80) for the TAP block group (p&lt;0.001). There was no difference in pain scores between the two groups. No complications related to the TAP block were reported.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n
