Sepsis
Conditions
Brief summary
Sepsis is a life-threatening organ dysfunction caused by the maladjusted response of the host to infection. It is a clinical syndrome with high mortality. Studies have confirmed that many cytokines play a vital role in the pathogenesis of sepsis. Ulinastatin (UTI) is a glycoprotein that exists in human blood and can be isolated and purified from human urine. It is a broad-spectrum protease inhibitor. Previous studies have shown that Ulinastatin may have the effect of treating sepsis. 120 septic patients with systemic inflammatory response syndrome would be recruited and randomly assigned to the ordinary dose group, high dose group and placebo control group according to the ratio of 1:1:1. The trial will be followed up on days 0, 1, 3, 5, 7 and 28. Sofa on day 7 compared with baseline and all-cause mortality on day 28 were investigated to explore the efficacy of ulinastatin in the treatment of adult sepsis patients with systemic inflammatory response syndrome.
Detailed description
The study plans to recruit 120 septic patients with systemic inflammatory response syndrome. After signing the informed consent, they will be included as day 0. They will be randomly assigned to the ordinary dose group, high dose group and placebo control group according to the ratio of 1:1:1, and the evaluation of basic clinical information of subjects will be supplemented and improved.The ordinary dose group will receive 400000 units of ulinastatin, which will be injected intravenously every 8 hours, The high-dose group will receive 800000 units of ulinastatin intravenously every 8 hours, and the control group will use equal volume solvent (50ml normal saline) as placebo intravenously every 8 hours. When the patient does not have systemic inflammatory response syndrome, the dose will be halved and then continue to be used for 2 days. The total course of Ulinastatin injection shall be at least 3 days. Inclusion criteria: 1\) Adults ≥ 18 years old and ≤ 80 years old 2) meet the sepsis-3.0 standard specified by the American Society of critical care medicine and the European Society of critical care medicine 3) sepsis diagnosis time \< 48h 4) systemic inflammatory response syndrome (SIRS) 5) obtain the informed consent signed by the patient or authorized immediate family members Exclusion criteria: 1\) Congestive heart failure, NYHA grade IV cardiac function, cerebrovascular accident or acute coronary syndrome within 3 months, cardiac arrest in this hospital or within 7 days, non infectious cardiogenic shock, uncontrolled acute bleeding 2) severe chronic liver disease (child Pugh grade C), liver parenchymal disease with significant portal hypertension Acute liver failure 3) chronic renal failure, who had received dialysis treatment before enrollment 4) severe abnormal coagulation function: isth-dic score ≥ 5 points 5) significant immune abnormalities / damage: organ or bone marrow transplantation and moderate and severe leucopenia within 3 months before screening, such as neutrophils \< 1.5 × 109 / L, received radiotherapy or chemotherapy within 3 months, HIV seropositive, hematological / lymphatic system tumor active period 6) received Xuebijing, thymosin or gamma globulin treatment within 3 months before study enrollment 7) others: allergic to study drugs, pregnancy, lactation, participated in other clinical trials within 3 months, and other situations that researchers think are not suitable to participate. The trial will be followed up on days 0, 1, 3, 5, 7 and 28. The changes of sofa on day 7 compared with baseline, all-cause mortality on day 28, ICU hospitalization time, antibiotic use time, SIRS duration, vasoactive drug time, mechanical ventilation time, CRRT time, infection and inflammation indexes, coagulation and fibrinolysis indexes, liver function, renal function, nervous and mental system function and endothelial cell function were compared, To explore the efficacy of ulinastatin in the treatment of adult sepsis patients with systemic inflammatory response syndrome.
Interventions
DRUGUlinastatin
Patients would be given 400000 or 800000units of ulinastatin (specification: 100000 units / vial) dissolved in 50 ml of 0.9% normal saline intravenously for at least 1 hour, once every 8 hours. It is evaluated by the attending doctor every day. When the patient does not have systemic inflammatory response syndrome (SIRS), halve the dose and continue to use it for 2 days, with a total course of treatment of at least 3 days
DRUGPlacebo
Patients would be given 50 ml of 0.9% normal saline intravenously for at least 1 hour once every 8 hours.It is evaluated by the attending doctor every day. When the patient does not have systemic inflammatory response syndrome (SIRS), continue to use it for 2 days, with a total course of treatment of at least 3 days.
