Transcranial Doppler (TCD) is widely used to investigate the effects of anesthetic drugs on
cerebral blood flow. Its repeatability and non‐invasivity makes it an ideal, first choice …

Transcranial Doppler ultrasonography (TCD) was introduced in 1982 by Aaslid and
colleagues5 as a non-invasive technique for monitoring blood flow velocity (FV) in the basal …

Transcranial Doppler sonography (TCD) constitutes an advance in noninvasive monitoring
of the cerebral circulation. However, as long as the diameter and cross-sectional area of the …

Aim Although adverse effects on cerebral blood flow have been reported, intravenous
anaesthetic and sedative agents are often used in neurosurgical patients. Monitoring of …

Introduced in 1982 by Aaslid and colleagues, 1 transcranial Doppler (TCD) ultrasonography,
sometimes termed a “stethoscope for brain,” has become one of the most useful methods of …

Transcranial Doppler sonography (TCD) has gained increasing relevance since its
introduction by Aaslid in 1982. Basal cerebral arteries are insonated with a 2-MHz …

Transcranial Doppler sonography (TCD) has gained in relevance for noninvasive monitoring
of the cerebral circulation during the perioperative period. As long as the diameters of the …

Intracranial hypertension can occur with induction of anesthesia; however, the clinical
significance of this is unclear. We used transcranial Doppler (TCD) ultrasonography in …

Systolic, diastolic, and mean blood flow velocity in the middle cerebral artery (Vs, mca; Vd,
mca; Wm, mca) and pulsatility (Vs-Vd)/Vm of the waveform obtained were recorded in 51 …

The effects of compromised cerebral hemodynamics on intracranial blood flow velocity
patterns (BFV) were studied by noninvasive transcranial Doppler sonography (TCD) …
