Influence of High Vitamin C Dose on Lactate During and After Extracorporeal Circulation
December 30, 2022 updated by: Andreja Möller Petrun, MD, PhD, University Medical Centre Maribor
"Influence of High Vitamin C Dose on Lactate During Extracorporeal Circulation for Heart Surgery and During the 24 Hours Thereafter." (Double Blind Prospective Randomised Study)
The aim of our study is to find out whether high doses of vitamin C before cardiopulmonary bypass and during the first 24 hours after that have and impact of lowering the incidence of hyperlactatemia.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Vitamin C
2g vitamin C (ascorbic acid) iv before cardiopulmonary bypass, 2 g vitamin C iv before removing the aortic clamp, 1g vitamin C iv 8 h after aortic clamp removal and every 8 h thereafter(2 times)
