Purpose We investigated cerebral perfusion pressure (CPP) at the time loss of cerebral
blood flow (CBF) occurred during brain death (BD). We hypothesized that a critical closing …

Purpose We investigated whether a critical rise of intracranial pressure (ICP) leading to a
loss of cerebral perfusion pressure (CPP) could serve as a surrogate marker of brain death …

Background Clinical investigations of brain death are supposed to prove absence of
cerebral perfusion. However, only limited data are available documenting intracranial …

Background Monitoring the cerebral blood flow (CBF) is crucial when caring for patients in
neurological intensive care units (NICU). Changes in CBF, either due to hypo-or …

Since 1986, transcranial Doppier ultrasonography (TCD) has been used in our department
to assess cerebral blood flow velocities (FV) in patients developing intracranial circulatory …

Background The diagnosis of brain death (BD) is complex. For this reason, we aimed to
evaluate the accuracy of power mode transcranial Doppler (PMD-TCD) in diagnosing BD …

Background Monitoring the injured brain is an integral part of the management of severely
brain injured patients in intensive care. Brain-specific monitoring techniques enable focused …

Background. Cerebral blood flow (CBF) volume can be measured at bedside by color
duplex flowmetry of the extracranial cerebral arteries. In neurointensive care patients, we …

Objective Barbiturate therapy or hypothermia precludes proper diagnosis of brain death
either clinically or by EEG. Specific intracranial flow patterns indicating cerebral circulatory …

Object. The authors studied the reliability of a new method for noninvasive assessment of
cerebral perfusion pressure (CPP) in head-injured patients in which mean arterial blood …
