简要总结
This study aims to evaluate the role of angiotensin II, AT1, and AT2 on catecholomine responsive and catecholomine resistant septic shock, and the effect of hydrocortisone traetment on catecholomine resistant septic shock and angiotensin II, AT1, and AT2.Angiotensin II can be used as a biomarker of vasoplegia observed in refractory septic shock unresponsive to catecholamine. In these patients; therapeutic effect of hydrocortisone on hypotension was performed by decreasing AT 2 level, AT2 should be investigated as a therapeutic target in the treatment of vasoplegia-induced hypotension and SVRI measured by minimally invasive cardiac output method suggests that it can be used as a useful parameter in the diagnosis and follow-up of vasoplegia.
详细描述
This study will be enrolled 40 patients diagnosed with septic shock according to Sepsis 3 criteria. The patients with septic shock who needed a noradrenaline infusion rate of up to 0.5µg/kg/min to maintain MAP>65 mmHg will be classified as control group (n=20) and the ones who required a noradrenaline infusion rate above 0.5µg/kg will be classified as hydrocortisone group (n=20). Blood samples will be taken for analysis of plasma angiotensin II, AT1, AT2 levels at the time of diagnosis, one hour after and on the 3rd day of the bundle and the hydrocortisone treatment. Hemodynamic parameters simultaneously obtain by continuous minimal invasive cardiac output measurement method will record.
