Study Details

Study Description

Brief Summary

Hypoxic-ischaemic brain injury (HIBI) is the main cause of death in patients who are comatose after resuscitation from cardiac arrest. Current guidelines recommend to target a mean arterial pressure (MAP) above 65 mmHg to achieve an adequate organ perfusion. Moreover, after cardiac arrest, cerebral autoregulation is dysregulated and cerebral blood flow (CBF) depends on the MAP. A higher blood pressure target could improve cerebral perfusion and HIBI. Transcranial Doppler (TCD) is a non-invasive method to study CBF and its variations induced by MAP.

The aim of this study is to test the feasibility of an early-goal directed hemodynamic management with TCD during the first 12 hours after return of spontaneous circulation (ROSC).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Cerebral hypoperfusion (group A)

Cerebral hypoperfusion will be defined by an abnormal TCD at inclusion (t0) when two of the three measured values are abnormal using the following thresholds: Vm < 30 cm/s, Vd < 20 cm/s, PI > 1.4.

Other: MAP increased to optimize cerebral blood flow
MAP will be increased to 90-100 mmHg with norepinephrine. If TCD is still abnormal with a MAP of 90-100 mmHg, MAP will be increased to 100-110 mmHg. At each step, all CBF determinants will be recorded as well as cardiac output and Veinous jugular oxygen saturation (SvjO2). When TCD is normalized with no complications, MAP will be maintained at 90-100 or 100-110 mmHg during 24 hours.

Active Comparator: Normal cerebral perfusion (group B)

Normal cerebral perfusion will be defined by a normal TCD at inclusion (t0) when two of the three measured values are normal using the following thresholds: Vm > 30 cm/s, Vd > 20 cm/s, PI < 1.4.

Other: MAP between 65 and 85 mmHg
MAP will be maintained between 65-85 mmHg, using a norepinephrine infusion as needed.

Outcome Measures

Primary Outcome Measures

  1. Proportion of patients in whom the transcranial doppler goal directed therapy will result in a modification of MAP targets [In the first hour after inclusion]

    Proportion of patients in whom transcranial doppler goal directed therapy will result in a modification of MAP targets.

Secondary Outcome Measures

  1. Cerebral blood flow modifications induced by increasing MAP [At the 6th, 12th, 24th, 48th and 72nd hour after inclusion]

    Transcranial doppler data modifications induced by increasing MAP to 90-100 mmHg and 100-110 mmHg.

  2. Cerebral oxygenation modifications induced by increasing MAP [At the 6th, 12th, 24th, 48th and 72nd hour after inclusion]

    Bulb jugular venous oxygen saturation modifications induced by increasing MAP at 90-100 mmHg and 100-110 mmHg.

  3. Undesirable events induced by increasing MAP [At te 24th hour after inclusion]

    Number of cardiovascular events defined by new onset of severe cardiac arrythmias, acute coronary syndromes, cardiogenic pulmonary edema, cardiogenic shock or cardiac arrest

  4. Undesirable events induced by increasing MAP [At the 72nd hour after inclusion]

    Number of neurologic events defined by intracranial hematoma or brain death

  5. Plasmatic concentrations of Neuron Specific Enolase [At the 72nd hour after inclusion]

    Neuron Specific Enolase (NSE) plasmatic concentrations at H+72h after cardiac arrest

  6. 28 day survival [28 days after inclusion]

    Proportion of patients alive 28 days after inclusion

  7. 90 days survival [90 days after inclusion]

    Proportion of patients alive 90 days after inclusion

  8. Measure of the degree of disability in the activities of daily living of the included patients [90 days after inclusion]

    Modified Rankin scale (MRS) 90 days after inclusion. The scale runs from 0-6, running from perfect health without symptoms to death. 0 - No symptoms. - No significant disability. Able to carry out all usual activities, despite some symptoms. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities. - Moderate disability. Requires some help, but able to walk unassisted. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent. - Dead.
