Objective:
Burn-induced shock can lead to tissue hypoperfusion, including the gut. We performed this study to describe burn patients at risk of acute mesenteric ischemia (AMI) with the aim to identify potential modifiable risk factors.
Methods:
Retrospective case-control study including adult severely burned patients between August 2012 and March 2017. Patients who developed AMI were matched to severely burned patients without AMI at a ratio of 1:3 (same year of admission, Abbreviated Burn Severity Index [ABSI], and Simplified Acute Physiology Score II [SAPSII]). Univariate and multiple regression analyses were performed.
Results:
Of 282 severely burned patients, 15 (5%) were diagnosed with AMI. In the AMI group, patients had a median (interquartile range) total body surface area (TBSA), SAPSII, and ABSI of 55 (25-63)%, 53 (39-70), and 11 (8-13), respectively. The AMI mechanism in all patients was nonocclusive. Decreased cardiac index within the first 24 h (H24 CI), higher sequential organ failure assessment score on day 1 (D1 SOFA), and hydroxocobalamin use were associated with AMI. Odds ratios were 0.18 (95% confidence interval [CI], 0.03-0.94), 1.6 (95% CI, 1.2-2.1), and 4.6 (95% CI, 1.3-15.9), respectively, after matching. Multiple regression analysis showed that only decreased H24 CI and higher D1 SOFA were independently associated with AMI. Ninety-day mortality was higher in the AMI group (93% vs. 46% [P = 0.001]).
Conclusions:
Burns patients with initial low cardiac output and early multiple organ dysfunction are at high risk of nonocclusive AMI.
