BACKGROUND For patients suffering from primary brain injury, monitoring intracranial pressure alone is not enough to reflect the dynamic intracranial condition. In our previous study, a segment of the pressure-volume curve can be expressed by the parabolic regression model with single indicator "a". The aim of this study is to evaluate if the indicator "a" can reflect intracranial conditions. ...

Intracranial pressure was continuously monitored in 23 patients aged between 24 hours and 20 months. Fourteen had severe infections of the central nervous system (CNS) and 9 sustained prolonged cerebral ischaemia. The intracranial pressure measured at catheter placement was not a reliable indicator of the intracranial pressure that developed during the course of the disease. The mean maximal in...

During induced hypotension with urapidil, measurements of intracranial pressure and of the ventricular volume-pressure response (intracranial compliance) were obtained in dogs with and without intracranial hypertension. A bolus of urapidil 50 mg plus an infusion of urapidil 8.2 +/- 1.2 mg min-1 decreased mean arterial pressure by 22 +/- 10% from control in group I (without intracranial hyperten...

Serial electrocardiographic (E.C.G.) recordings were taken in seven patients suffering from intracranial conditions, for which their intracranial pressure was directly and continuously monitored with a Konigsberg extradural transducer. The E.C.G. changes observed in patients with raised intracranial pressure were prominent U waves, ST-T segment changes, notched T waves, and shortening and prolo...

objectives upon completion of this presentation, participants will be able to: 1) recognize mri appearance of the spontaneous intracranial hypotension and idiopathic intracranial hypertension (pseudotumor cerebri). 2) review their various clinical and imaging presentations. conclusions in this presentation we will review imaging presentations of our several proved cases. as mentioned, there are...

OBJECTIVE To evaluate the effect of intermittent pneumatic leg compression on intracranial pressure and cerebral perfusion pressure in brain-injured patients. DESIGN Prospective, sequential patient study. SETTING Surgical/trauma ICU of a community hospital providing regional trauma care. PATIENTS Twenty-four adult, brain-injured patients (mean Glasgow Coma Scale score = 6) who required he...

BACKGROUND Some publications suggest a strong correlation between the intracranial pressure and the intraocular pressure. Other studies claim no correlation between these two physiologic variables. Our aim was to study whether the tonometry could be a useful method to evaluate intracranial pressure in patients with suspected intracranial abnormality. METHODS We evaluated the correlation betwe...

BACKGROUND Post-craniotomy intracranial air can be present in patients scheduled for air ambulance transport to their home hospital. We aimed to assess risk for in-flight intracranial pressure (ICP) increases related to observed intracranial air volumes, hypothetical sea level pre-transport ICP, and different potential flight levels and cabin pressures. METHODS A cohort of consecutive subdura...
