Detailed Description

Adult patients with septic shock were enrolled within 24 hours following admission to the Central Department of Intensive Care in Lithuanian University of Health Sciences Hospital Kaunas Clinics.

Participants were randomly assigned to a placebo or ascorbic acid group in a 1:1 ratio. They were resuscitated according to Surviving Sepsis Campaign Guidelines. Additionally, they received an intravenous infusion of ascorbic acid either placebo. The dose of ascorbic acid was 200mg/kg/24h divided into four equal parts for 96 hours. Sublingual microcirculatory measurements were obtained, using an incident dark field (IDF) device.
