Intracranial pressure: more than a number.
Many doctors involved in the critical care of head-injured patients understand intracranial pressure (ICP) as a number, characterizing the state of the brain pressure-volume relationships. However, the dynamics of ICP, its waveform, and secondarily derived indices portray useful information about brain homeostasis. There is circumstantial evidence that this information can be used to modify and...
متن کاملAcute hypercapnia improves indices of tissue oxygenation more than dobutamine in septic shock.
RATIONALE Hypercapnia has similar hemodynamic effects to those of a dobutamine infusion and may have relevance in the management of septic shock. OBJECTIVES To compare the effects induced by hypercapnia with those of dobutamine in a clinically relevant model of septic shock. METHODS Fecal peritonitis was induced in 21 anesthetized, invasively monitored, mechanically ventilated female sheep....
متن کاملStroke: More than a 'brain attack'.
Stroke is a life-altering event that potentially affects stroke survivors, their families, healthcare resources, and society in general. Stroke has often been described as 'brain attack', denoting emergency emphasis on the vascular pathology. Consequently, many national and provincial stroke strategies have emphasized vascular care through primary prevention strategies and thrombolysis. Despite...
متن کاملSometimes area counts more than number.
Using an interference paradigm, we show across three experiments that adults' order judgments of numbers, sizes, or combined area of dots in pairs of arrays occur spontaneously and automatically, but at different speeds and levels of accuracy. Experiment 1 used circles whose sizes varied between but not within arrays. Variation in circle size interfered with judgments of which array had more ci...
متن کاملTargeting brain tissue oxygenation in traumatic brain injury.
The management of patients with traumatic brain injury has evolved in the last several years, due to the introduction of new, invasive monitoring devices. The ability to monitor parameters other than measurements related to pressures has generated substantial interest. Brain tissue oxygenation monitoring has been consistently shown to provide prognostic information, as indicated by poor prognos...
