Septic Shock
Conditions
Keywords
norepinephrine, vasopressin, organ perfusion.
Brief summary
Patients with septic shock with norepinephrine \>0.25ug/kg/min were enrolled. Informed consent was obtained for inclusion in the study and random assignment into the combination or norepinephrine group. Contact the research assistant to obtain patient number information and print out the appropriate labels.Notify the ward dispensing nurse to open the experimental drug cassette (placed in the refrigerator 4℃ drug cabinet). Extract the corresponding experimental medication according to the patient label number, dispense it and send it to the ward, label it and hand it over to the bedside nurse to start using it. The time point at which the medication was connected to the patient and activated was recorded as the zero point for the start of the study. The data were monitored according to the time points specified in the study: baseline,0h , 6h, D1, D2, and post-drug withdrawal.
