Change of systemic vascular resistance In this study, in the beginning, the average value of systemic vascular resistance of patients was 2007, 6 ± 577, 7 dynes / sec / cm5, higher than a study by Bui Van Tam where septic shock patients had decreased systemic vascular resistance of 714 ± 243 dynes / sec / cm5 before being put on continuous hemodialysis even though they had received a high dose noradrenalin of 0, 91 ± 0, 69 µg / kg / phút 4.2.4.
