To examine the predictive value of an early transcranial Doppler ultrasound (TCD) study performed in the emergency department in patients with spontaneous subarachoniod hemorrhage (SAH) in good neurological condition, in order to know which patients are at high risk of developing delayed cerebral ischemia (DCI). ⋯ During the first 3 days, an increase of 21cm/s/24h in MCA-MV was associated with the development of symptomatic vasospasm. TCD is a useful tool for the early detection of patients at risk of DCI after SAH.

Hemodynamic monitoring is a tool of great value for the assessment of critically ill patients. It can not only detect and determine the source of hemodynamic instability, but also guide the choice of appropriate treatment and further evaluate its effectiveness. ⋯ Accordingly, the usefulness of monitoring systems should be evaluated not only on the basis of the accuracy and reliability of their measurements, but also on the ability to positively affect patient outcome. In this regard, many of the arguments against the use of hemodynamic monitoring are a consequence of non-protocolized use and of application not directed towards specific hemodynamic objectives of proven benefit for the patient.
