Purpose: The aim of this study was to assess the efficacy of intravenous hydrocortisone, ascorbic acid, and thiamine (HAT) combination therapy in complicated intraabdominal infection (cIAI) patients with septic shock.
Methods: This was a single-center, retrospective before-after clinical study comparing clinical outcomes of cIAI patients with septic shock treated with HAT in a surgical intensive care unit (ICU). Delta modified sequential organ failure assessment (mSOFA) scores were evaluated to assess recovery of organ dysfunction. Additional outcomes included procalcitonin level change, daily vasopressor dosage, mean number of days free of mechanical ventilation in 28 days, and renal replacement therapy days.
Results: The delta mSOFA score (ICU admission mSOFA score minus 7th-day mSOFA score) was significantly higher in the HAT group than in the control group on the 7th day (2.30 vs. -0.90, P = 0.003). The median 7-day change in procalcitonin score was higher in the control group than in the HAT group (5.94 vs. 10.72, P = 0.041). The difference in vasopressor score between the 1st day and the 4th day was significantly higher in the HAT group (17.63 vs. 9.91, P = 0.005).
Conclusion: In our study of cIAI in patients with septic shock, administration of HAT therapy may improve the recovery from organ dysfunction.
