Mean arterial blood pressure and neonatal cerebral lesions.
Computerised continuous measurement of mean arterial blood pressure (MAP) and serial cranial ultrasonography in 33 infants of less than 31 weeks' gestation showed that a MAP of less than 30 mm Hg for over an hour was significantly associated with severe haemorrhage, ischaemic cerebral lesions, or death within 48 hours. No severe lesions developed with a MAP greater than or equal to mm Hg.
متن کاملEffect of Islamic fasting on mean arterial pressure
Introduction: World Health Organization (WHO) introduced hypertension as an epidemic in developing countries. However, hypertension is adequately controlled in only 12.5% of patients. The aim of this study was to evaluate the relationship between Ramadan fasting and mean arterial pressure (MAP). Methods: This clinical, observational study was carried out at Medical O.P.D of Jinnah Medical Coll...
متن کاملMean arterial pressure and intracranial pressure.
To the Editor:—We read with great interest the article by Petersen et al., which demonstrated the expected clinical response to the three anesthetic agents studied. An increase in arterial pressure may result in an increase in the cerebral perfusion pressure and reduce reflex cerebral vasodilatation, potentially resulting in reduced intracranial pressure. We note that the mean arterial pressure...

متن کاملArterial and venous contributions to near-infrared cerebral oximetry.
BACKGROUND Cerebral oximetry is a noninvasive bedside technology using near-infrared light to monitor cerebral oxygen saturation (Sco2) in an uncertain mixture of arteries, capillaries, and veins. The present study used frequency domain near-infrared spectroscopy to determine the ratio of arterial and venous blood monitored by cerebral oximetry during normoxia, hypoxia, and hypocapnia. METHOD...
