abstract objective: to investigate the anesthesia-postoperative awakening time (at) of hepatitis- related cirrhosis patients and their relations to grading scores, portal venous pressure (pvp), prealbumin (pa), and age, to predict postoperative at and provide a basis for adjustment of anesthetic doses during operation. methods: atotal of 71 patients with hepatic cirrhosis and hypersplenism at a...

THE COMBINATION of two physical signs, increasing venous pressure and palpable decrease in arterial systolic and pulse pressure with inspiration in constrictive pericarditis was pointed out by Kussmaul.1 Wood2 alluded to these signs as evidence for pericardial effusion and attributed the rise in venous pressure to an inspiratory rise in intrapericardial pressure. Dock3 subscribed to this view, ...

PURPOSE OF REVIEW The focus of intraoperative monitoring is moving away from invasive monitoring. This has been attributed to procedure time, cost, and the known risks, which include carotid artery puncture, arrhythmia, pneumothorax, and infection. Until recently, the venous system's contribution to the circulatory system has been incorrectly identified as being insignificant. This article summ...

Increases in renal venous pressure have been shown to consistently increase renal interstitial pressure; however, not until renal interstitial pressure is increased threefold is a natriuresis noted in normal animals. Since the intrarenal angiotensin II (Ang II) concentration has been postulated to increase with increasing renal venous pressure, the antinatriuretic action of Ang II could overrid...

Arterial blood pressure was recorded through a Cournand needle inserted into the brachial artery. Distensibility of the capacity vessels was measured by comparing the increase in hand volume resulting from intermittent obstruction of the venous return from the hand with the simultaneous rise in venous pressure of the hand. Hand volume changes were measured with a waterfilled plethysmograph of 5...

BACKGROUND The measurement of the hepatic venous pressure gradient may identify a suboptimal response to beta-blockers in patients with varices at risk for bleeding. However, the cost-effectiveness of routine hepatic venous pressure gradient measurements to guide primary prophylaxis has not been examined. METHODS We used decision analysis to evaluate two hepatic venous pressure gradient measu...

BACKGROUND Some prior studies have shown that elevated mean central venous pressure in certain patient populations and disease processes may lead to poor prognosis. However, these studies failed to generalize the concept of elevated central venous pressure (ECVP) load to all patients in critical care settings because of the limited cases and exclusive cohorts. The aim of the study was to invest...

This study aimed to develop and assess an application software for the teaching of the procedure Manual Measurement of the Central Venous Pressure which can be used in mobile devices. The research was conducted in three phases (Survey of needs; Methodology for multimedia application development and evaluation of the multimedia application).The multimedia was the method chosen because it favors ...
