Primary Outcome Measures:
  • Predictive value of respiratory variation in brachial artery peak velocity before volume expansion assessed by ROC curve. We defined responser as patients that increased stroke volume index equal or more than 15% after fluid administration. [ Time Frame: immediately after volume expansion ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evaluate the predictive value of pulse pressure variation for predicting hemodynamic response to fluid administration, comparing with the predictive value of respiratory variation of brachial artery peak velocity. [ Time Frame: immediately after fluid administration ] [ Designated as safety issue: No ]
  • Evaluate the predictive value of stroke volume variation for predicting hemodynamic response to fluid administration, comparing with the predictive value of respiratory variation of brachial artery peak velocity. [ Time Frame: immediately after volume expansion ] [ Designated as safety issue: No ]

Groups/Cohorts Assigned Interventions
Acute circulatory failure
Patients for whom the decision to give fluids was taken because the presence of one or more clinical signs of acute circulatory failure.
Other: Fluid administration
500 ml of synthetic colloid (Voluven®, hydroxyethylstarch 6%; Fresenius, Bad Homburg, Germany) infused over 30 minutes

Detailed Description:

Predicting the hemodynamic response to fluid administration (or fluid responsiveness) in critical ill patients is still a matter of concern, since fluid overload could worse the clinical situation of these patients. Parameters of fluid responsiveness usually require an invasive monitoring (like arterial pulse pressure variation).

We hypothesize that noninvasive evaluation of respiratory variation of peak velocity in brachial artery using Doppler ultrasound could provide a feasible estimation on fluid responsiveness in mechanically ventilated patients with acute circulatory failure.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Critical ill patients with controlled mechanical ventilation and acute circulatory failure.

Criteria

Inclusion Criteria:

  • Patients with controlled mechanical ventilation, equipped with an indwelling radial artery catheter and for whom the decision to give fluids will be taken because the presence of one or more clinical signs of acute circulatory failure:

    • systolic blood pressure <90 mmHg (or a decrease >50 mmHg in previously hypertensive patients)
    • the need of vasopressor drugs
    • oliguria (urine output <0.5 ml/kg/min for at least 2 h)
    • tachycardia
    • delayed capillary refilling
    • the presence of skin mottling

Exclusion Criteria:

  • Contraindication for the volume administration: evidence of fluid overload and/or of hydrostatic pulmonary edema
  • Patients with instable cardiac rhythm
