conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...
conclusions noninvasive assessment of the patient hydration condition using the ultrasound is a simple and practicable measure in emergency. with regard to the considerations, it is possible to estimate cvp via diameter measurement and cross-section of the central veins. results twenty patients with the mean age of 60.3 were studied. the main reason for cardiac catheterization was shock. there ...
Background & Aim: The central venous pressure measurement is a common and important care provided by nurses in intensive units. The measurement should be according to the pre-defined standards. The purpose of this study was to evaluate the effect of using a checklist in measuring central venous pressure by nurses . Methods & Materials: This was a nonequivalent group design on 70 nurses w...
Background & objectives: Cardiopulmonary bypass often causes a stress hormonal response with subsequent changes in hemodynamic and organ perfusion. Human studies involving cardiopulmonary bypass have shown that very low doses of ketamine can attenuate inflammatory and stress markers, without adverse effects. The aim of this study was to investigate whether low dose infusion of ketamine have hem...
Erectile dysfunction is an important problem for men and their families which has an organic cause in about 50 percent of cases. When there is a vasculogenic etiology for this defect, radiologic assessment is unavoidable. Cavernosometry and Cavernosography are ultimate procedures for diagnosis of venous leakage. There is no reliable data about this defects in Iran. The objective of this study w...

Assessment of the jugular venous pressure is often inadequately performed and undervalued. Here, we review the physiologic and anatomic basis for the jugular venous pressure, including the discrepancy between right atrial and central venous pressures. We also describe the correct method of evaluating this clinical finding and review the clinical relevance of the jugular venous pressure, especia...
Preplacement check of complete central venous pressure catheter assembly: Should it be made routine?
BACKGROUND AND PURPOSE Stroke-related tissue pressure increase in the core and penumbra determines regional cerebral perfusion pressure (rCPP) defined as a difference between local inflow pressure and venous or tissue pressure, whichever is higher. We previously showed that venous pressure reduction below the pressure in the core causes blood flow diversion-cerebral venous steal. Now we investi...
