Study on the Improvement of Microcirculation in Patients With Sepsis by Vitamin B6, Vitamin B12 and Vitamin C

Summary

Sepsis is a kind of disease with high morbidity and mortality in ICU. At present, there is no specific treatment, and its pathogenesis is mainly excessive oxidative stress. Anti-inflammatory, antioxidant and immune-regulating drugs may produce better therapeutic effects, while vitamin B6, vitamin B12 and vitamin C have anti-inflammatory, antioxidant and immune-regulating effects. The purpose of this study was to investigate whether vitamin B6, vitamin B12 combined with vitamin C can improve the microcirculation and organ dysfunction in patients with sepsis, and improve the survival rate of patients with sepsis. The study included 296 patients who met the inclusion criteria. After randomization, the experimental group was given intravenous vitamin B6 300mg qd in addition to the basic treatment of sepsis Vitamin B12 0.5mg q6h, vitamin C 50mg/kg q6h for 4 days. Control group 1 was given vitamin B6 300mg qd and vitamin B12 0.5mg q6h intravenously for 4 days. Control group 2 was injected with vitamin C 50mg/kg q6h intravenously for 4 days. Control group 3: The same dose of placebo (0.9% sodium chloride solution) was administered for 4 days. After medication, sublingual microcirculation image and radial artery resistance index of snus pit were detected and recorded according to the time required by the study protocol. The duration of use of pressor drugs, ventilator days, ICU stay, 28-day mortality, capillary refill time, changes in SOFA score and APACHEII score on day 3 and day 7 compared with baseline values at randomization, daily veno-arterial carbon dioxide differential pressure (GAP) and central venous oxygen saturation were recorded. After the end of the experiment, statistical analysis of the data was carried out to further explore the test results
