简要总结
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.
详细描述
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.

入选标准
- •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.
排除标准
- •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.
结局指标
主要结局
Incidence of hypotension
时间窗: The first 24 hours after the start of reduction of one of the vasopressors.
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.
次要结局
- Length of stay in intensive care unit(In a 28-day follow-up, from the beginning of reduction of one of the vasopressors.)
- Mortality(Mortality in a 28-day follow-up, from the beginning of the 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.)
