Abstract

In 12 patients with life-threatening neurological deficits from vasospasm refractory to other measures, high dose barbiturate therapy was used in an attempt to prevent permanent changes in the brain. In each case angiography was performed and intracranial pressure was measured. Dexamethasone, a low molecular weight dextran, and mannitol were administered. If intracranial pressure (ICP) was elevated, drainage of cerebrospinal fluid and hyperventilation were used. Arterial pressure was maintained at not less than 140/90 preoperatively and 180/100 postoperatively. Barbiturate therapy was continued until vasospasm decreased angiographically and ICP was normal. Eleven of the 12 patients perished. One had a fatal rebleed. One died of an iatrogenic hemothorax. Four died from uncontrollable intracranial hypertension. One improved slightly and then died from a cardiac arrhythmia. One died of increased ICP when her ventriculostomy malfunctioned. One improved and was responding purposefully to pain, only to die suddenly with a low ICP. Two patients became awake and responsive to verbal commands; 1 of these died from Klebsiella meningitis and the other died from an intracerebral hematoma. In the 3 patients in whom hypothermia was also used...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
