Early Versus Differed Arterial Catheterization in Critically Ill Patients With Acute Circulatory Failure:

The objective of the present research is a combination of a one-sided test of non-inferiority and a one-sided test of superiority. A stepped approach will be used to evaluate these hypotheses:

1. a less invasive intervention (i.e., no indwelling arterial catheter insertion until felt absolutely needed, according to consensual and predefined safety criteria) is non inferior to usual care (i.e., systematic indwelling arterial catheter insertion in the early hours of shock) in terms of mortality at day 28 (non-inferiority margin of 5%). 2. a less invasive intervention is not only non-inferior but also superior to usual care in terms of mortality.

Multi-centre, pragmatic, randomised, controlled, open, two-parallel group, non-inferiority clinical trial.

Treatment and study plan

Non-invasive strategy

Procedure

No indwelling arterial catheter insertion will be allowed during the first 28 days, excepted if predefined safety criteria (indicating absolute need of indwelling arterial catheter insertion) are reached.

In the "non-invasive" group, automated oscillometric monitor will be used to monitor BP (blood pressure).

Control strategy

Procedure

An indwelling arterial catheter will be inserted as soon as possible (within the first four hours after randomization) and will be maintained except in case of indwelling arterial catheter futility, suspected or proven indwelling arterial catheter related infection or thrombosis (at discretion of attending physician) until day 28 or ICU (Intensive Care Unit) discharge (whichever comes first). After day 28, clinicians may choose to maintain or to remove indwelling arterial catheter.

Primary outcomes

  1. All-cause mortality by 28 days after randomisation

    Time frame: Patients will be followed from randomization to day 28

Secondary outcomes

  1. To account for the potential bias brought by deaths occurring as the result of life-sustaining treatments withdrawal/withholding, as frequently encountered in intensive care unit, the investigators will record such events

    Time frame: From inclusion to Day 35

  2. Cumulative incidence of death

    Time frame: From inclusion through Day 90

  3. Cumulative survival free of indwelling arterial catheter insertion

    Time frame: From inclusion through Day 90

  4. Number of patients who underwent indwelling arterial catheter insertion, in both groups

    Time frame: From randomization to Day 28

  5. Evolution of daily Sequential Organ Failure Assessment (SOFA) score

    Time frame: During the first seven days

    The score (ranged from 0 to 24, the worth outcome) is based on six sub-scores (each ranged from 0 to 4, the worth outcome), one for each respiratory system, neurological, cardiovascular, hepatic, renal and coagulation.

  6. Daily amount of intravenous fluid given for rapid vascular volume expansion

    Time frame: From Day 1 to Day 7

  7. Duration of mechanical ventilation

    Time frame: From inclusion to Day 28

  8. Ventilator-free days

    Time frame: From Day 1 to Day 28

    Patients dying between randomisation and Day 28 will be assigned a 0 value; for survivors at Day 28, all the days free of invasive mechanical ventilation through an endotracheal tube within the 28-day period will be taken into account

  9. Proportion of patients treated by renal-replacement therapy

    Time frame: Between Day 1 and Day 28

  10. Renal replacement therapy-free days

    Time frame: From Day 1 to Day 28

    Time frame: Between Day 1 and Day 28

  12. Vasopressor therapy-free days

    Time frame: From Day 1 to Day 28
