Clinical Trial 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.

Description:

A randomized, open-case clinical trial with 2 arms will be conducted: initial suspension of norepinephrine (norepinephrine group) versus initial vasopressin (vasopressin group).

The selection of patients who will participate in the study will be for convenience. The randomization of the patients will be done by opaque envelopes 1:1, grouped into blocks, generated by random numbers.

The study will be carried out in the intensive care unit of a tertiary hospital in Southern Brazil, taking into account the clinical and surgical patients. In the intensive care unit, after randomization, patients will be identified by posters, attached to the bed. The titration of vasoactive drugs will be criterion of the assistant team.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Mortality	Evaluation of the mortality in first 28 days after discontinuation of one of the vasoactive drugs.	Mortality in a 28-day follow-up, from the beginning of the reduction of one of the vasopressors.
Secondary	Length of stay in intensive care unit	Evaluation of the length of stay in intensive care unit.	In a 28-day follow-up, from the beginning of reduction of one of the vasopressors.
Secondary	Time of use of the vasoactive drugs	Quantify the time spent using vasoactive drugs after the removal of the first drug (norepinephrine or vasopressin) in days.	Follow-up of up to 7 days, from the beginning of reduction of one of the vasopressors.
Secondary	Incidence of arrhythmias	Quantify the incidence of arrhythmias with hemodynamic repercussions in 24 hours after withdrawal of the first drug (norepinephrine or vasopressin). This group includes events in which hemodynamic worsening required electrical or chemical cardioversion.	The first 24 hours after the start of reduction of one of the vasopressors.
Secondary	Incidence of hemodialysis	Quantify the incidence of hemodialysis, independent of dialysis modality, excluding patients on dialysis chronic.	The first 72 hours after the start of reduction of one of the vasopressors.
