Estimation of central arterial pressure from the radial artery in patients undergoing invasive neuroradiological procedures.

Backgrounds: Central arterial pressure can be derived from analysis of the peripheral artery waveform. The aim of this study was to compare central arterial pressures measured from an intra-aortic catheter with peripheral radial arterial pressures and with central arterial pressures estimated from the peripheral pressure wave using a pressure recording analytical method (PRAM).

Methods: We studied 21 patients undergoing digital subtraction cerebral angiography under local or general anesthesia and equipped with a radial arterial catheter.

[Analysis of quality of life following hospital discharge among survivors of severe sepsis and septic shock].

Objective: Describe the impact of severe sepsis and septic shock on patients' quality of life following hospital discharge.

Methods: A controlled study conducted in two general hospitals of Joinville, Santa Catarina, Brazil, of in-patients with severe sepsis or septic shock during the period of August 2005 through November 2007. The patients were contacted by telephone between June and November 2009.

Cardiogenic shock associated with subarachnoid hemorrhage.

Systemic complications are frequent in subarachnoid hemorrhage patients. Among these complications, electrocardiographic abnormalities simulating ischemic cardiomyopathy may occur, possibly associated with myocardial dysfunction. This manuscript aims to report a case of subarachnoid hemorrhage associated with myocardial dysfunction and cardiogenic shock.
