A noninvasive method for monitoring cerebral perfusion during cardiopulmonary resuscitation.
This study evaluates the use of transcranial Doppler (TCD) ultrasound in assessing the changes experienced by the cerebral circulation during cardiopulmonary resuscitation (CPR) and compares it with measurements of internal carotid artery (ICA) flow rates (ultrasonic flow-meter measurements) and cerebral blood flow (CBF) (radioactive-microsphere measurements) in a porcine cardiac arrest model undergoing closed chest CPR. ⋯ TCD can provide on-line information about cerebral perfusion during CPR.

Prostacyclin improves glucose utilization in patients with sepsis.
In patients with sepsis, impaired glucose metabolism and altered microcirculatory blood flow are common findings. Prostacyclin (PGI2) improves tissue oxygenation, indicated by enhanced oxygen delivery (DO2) and oxygen uptake (VO2). The purpose of this study was to explore whether these effects are associated with improved glucose utilization. ⋯ Improving tissue perfusion and oxygenation with PGI2 may also modify the impaired glucose metabolism by increasing glucose oxidation rate in patients with sepsis, suggesting enhanced adenosine triphosphate production.
