A nationwide analysis of the use and outcomes of perioperative epidural analgesia in patients undergoing hepatic and pancreatic surgery

BACKGROUND: We sought to define trends in the use of epidural analgesia (EA) for hepatopancreatic procedures, as well as to characterize inpatient outcomes relative to the use of EA. METHODS: The Nationwide Inpatient Sample database was queried to identify all elective hepatopancreatic surgeries between 2000 and 2012. In-hospital outcomes were compared among patients receiving EA vs conventional analgesia using propensity matching. RESULTS: EA utilization was 7.4% (n = 3,961). The use of EA among minimally invasive procedures increased from 3.8% in 2000 to 9.1% in 2012. The odds of sepsis (odds ratio [OR] .72, 95% confidence interval [CI] .56 to .93), respiratory failure (OR .79, 95% CI .69 to .91), and postoperative pneumonia (OR .77, 95% CI .61 to .98), as well as overall in-hospital mortality (OR .72, 95% CI .56 to .93) were lower in the EA cohort (all P <.05). In contrast, no association was noted between EA and postoperative hemorrhage (OR .81, 95% CI .65 to 1.01, P = .06). CONCLUSIONS: EA use among patients undergoing hepatopancreatic procedures remains low. After controlling for confounding factors, EA remained associated with a reduction in specific pulmonary-related complications, as well as in-hospital mortality. (C) 2015 Elsevier Inc.
