NCT01800877

Brief Summary

The purpose of this research study is to determine if it is better to give vasopressors to patients to maintain a higher blood pressure target versus a lower blood pressure target. This study is important because the information we find out will help us know how best to administer vasopressors in patients with shock in the ICU.

Outcome Measures

Primary Outcomes (1)

  • MAP While on Vasopressors

    The primary feasibility outcome will be the difference in the means of mean arterial pressures (MAP) while on vasopressors and we define acceptable adherence (the threshold for feasibility) by a difference of at least 5 mmHg while on vasopressors (rejecting the null hypothesis of a difference of less than 5 mmHg - see proposed sample size).

    While on vasopressors from randomization until 28 days

Study Arms (2)

Liberal Approach

OTHER

In the liberal approach group, we will titrate vasopressors to maintain mean arterial pressures between 75 and 80 mmHg.

Drug: Vasopressors

Restrictive Approach

OTHER

We will titrate vasopressors to maintain mean arterial pressures between 60 and 65 mmHg.

Drug: Vasopressors

Interventions

Also known as: phenylephrine, dopamine, norepinephrine, epinephrine, vasopressin

Eligibility Criteria

Age17 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Who are receiving vasopressors for distributive shock
  • Who are older than 16 years of age at the time of eligibility.
  • Who are under the direct care of the ICU team regardless of location.
  • Who have received a minimum of 30 mL/kg of intravenous fluids (2100 mL for a 70 kg patient) before enrolment OR the most responsible physician has good reasons to believe that more fluid resuscitation is no longer required and could be harmful.
  • Who the treating physician believes will need vasopressors for at least 6 hours once enrolled.

You may not qualify if:

  • Have received vasopressors for more than 24 consecutive hours; if vasopressors are discontinued for \>= 2 hours then restarting vasopressors will constitute a distinct vasopressor episode and the clock will be reset.
  • Are judged by the treating physician to be in obvious cardiogenic shock after an acute myocardial infarction (based on new ST segment elevations on ECG or obvious echocardiographic findings).
  • Have obvious haemorrhagic shock as a consequence of a clearly identified source of blood loss.
  • Require vasopressors after cardiac surgery as a result of cardiopulmonary bypass-induced hypotension.
  • Who have a specific indication for catecholamine therapy other than shock (i.e. angioedema or intracranial hypertension).
  • If the attending team has agreed to withhold or withdraw life sustaining care.
  • Concurrent enrollment in interventional trials that do not meet guidelines (see ccctg.ca) for co-enrollment (co-enrollment is permissible if there is no potential interaction between the protocols; this will be addressed case by case).
  • Prior randomization in this study.
