Sepsis, Septic Shock
Conditions
Brief summary
Rudiger and Singer suggested strategies for refining adrenergic stress (decatecholaminization). They proposed the use of dexmedetomidine and vasopressin to reduce the catecholamine load during sepsis. The investigators will use vasopressin as the primary vasopressor and a heart rate-calibrated dexmedetomidine infusion in septic shock patients. The investigators of the current study will use DEXPRESSIN in septic shock patients to investigate the effects of decatecholaminization on in-hospital mortality.
Detailed description
The investigator will include 260 patients with septic shock. The study will compare the use of vasopressin as the first-line vasopressor in septic shock in addition to the dexmedetomidine infusion as in the DecatSepsis trial versus the standard of care. The standard of care is guided by the Surviving Sepsis campaign in 2021. The main outcomes of the study are in-hospital mortality, norepinephrine equivalent dose, ICU scores, and inflammatory markers.
Interventions
This group will receive vasopressin as the first-line vasopressor. DEX will be started after hemodynamic stabilization if the heart rate is \>90 beats per minute (bpm). NE infusion will be the second-line vasoactive drug.
This group will receive conventional treatment according to the SSC 2021 guidelines. This group will receive vasopressin as the second line after NE and will not receive DEX.
