Brief Summary

Although there is consensus in the literature on hemodynamic management of septic shock in the resuscitation phase, the best way to conduct the weaning of vasopressor drugs in the stabilization phase remains open. The present study aims to study the incidence of hypotension in the weaning phase of vasopressor drugs- norepinephrine and vasopressin.

Conditions

Septic Shock

Keywords

vasoconstrictor agents; sepsis; critical care; vasopressin

Outcome Measures

Primary Outcomes (1)

• Incidence of hypotension

  Evaluation of the incidence of hypotension in the first 24 hours after discontinuation of one of the vasoactive drugs: norepinephrine or vasopressin. It is defined as hypotension the drop in mean blood pressure below 65 mmHg, triggering one or more of the following measures: a) administration of crystalloid or colloid aliquot, b) dose increase of the remaining vasoactive drug or c) re-establishment of the drug vasoactive paused.

  The first 24 hours after the start of reduction of one of the vasopressors.

Secondary Outcomes (5)

• Mortality

  Mortality in a 28-day follow-up, from the beginning of the reduction of one of the vasopressors.

• Length of stay in intensive care unit

  In a 28-day follow-up, from the beginning of reduction of one of the vasopressors.

• Time of use of the vasoactive drugs

  Follow-up of up to 7 days, from the beginning of reduction of one of the vasopressors.

• Incidence of arrhythmias

  The first 24 hours after the start of reduction of one of the vasopressors.

• Incidence of hemodialysis

  The first 72 hours after the start of reduction of one of the vasopressors.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients with septic shock, according to the definitions of SEPSIS - 3: septic and hypotensive patients, demanding use of vasoactive drug and lactate greater than 2 mmol/L (18 mg/dL).
• Patients admitted to the intensive care unit.
• Patients in need of associated use of norepinephrine and vasopressin.

You may not qualify if:

• Patients in whom discontinuation of norepinephrine or vasopressin has been given by decision of the assistant team, from a perspective of prioritizing palliative care.
• Patients using a combination of a third drug, with the effect of predominantly vasopressor - adrenaline.
