Hemodynamic Changes Attending Anqiocardioqraphy

Radiology, 1967
Hypertonicity is an outstanding characteristic of the contrast solutions used for radiographic visualization of the cardiovascular system. The osmolarity of a number of these agents ranges from 1,300 to over 2,300 milliosmols per liter, values severalfold greater than that of blood serum (6, 23).

Hemodynamic changes in iliofemoral disease

Phlebology: The Journal of Venous Disease, 2014
Background Iliofemoral venous obstruction, caused by post-thrombotic disease, can be treated by percutaneous angioplasty and additional stenting with good results. However, no hemodynamic parameter determining the need for treatment has been defined. This article describes the preliminary results of a study investigating the pressure changes occurring ...

Hemodynamic Changes during Protamine Administration

Anesthesia & Analgesia, 1983
Hemodynamic responses to intravenous protamine sulfate in 40 patients were evaluated. The dose of protamine administered was calculated as adequate to reverse residual heparin as measured by the activated clotting time (ACT). Thirty patients (n = 30) received protamine at a rate of 0.5 mg/kg/min and the remainder (n = 10) received protamine at a rate ...

Hemodynamic Changes During Long Meditation

Applied Psychophysiology and Biofeedback, 2004
Changes in heart rate (HR) and blood pressure (BP) in advanced male meditators during 1 hr of meditation were compared with matched control participants resting for 1 hr. Also, changes in HR and BP during 3-hr meditation were analyzed. HR was recorded continuously during meditation (n = 38) and the control rest (n = 21).

Fetal hemodynamic changes after amniotomy

Acta Obstetricia et Gynecologica Scandinavica, 2005
The aim of the study was to assess fetal vascular blood flow after amniotomy.This was a prospective observational study. Thirty-five women with singleton pregnancy beyond 36 weeks of gestation, who underwent amniotomy, were recruited. The pulsatility indices of the fetal middle cerebral artery (MCA), the renal artery, and the ductus venosum were ...

Hemodynamic changes after strabismus surgery

Strabismus, 2000
The aim of this study was to investigate the hemodynamic changes that may occur in the retrobulbar circulation after strabismus surgery, using color Doppler ultrasonography (CDI).Fifteen healthy volunteers (control group, n=15) and sixteen patients diagnosed with strabismus were enrolled in the study.

Hemodynamic Changes of Aortic Regurgitation

The American Journal of the Medical Sciences, 1997
Hemodynamic changes associated with acute AR include a rapid increase in LV pressures during diastole, markedly elevated pressures at end diastole, and premature closure of the mitral valve. Systemic diastolic pressures may be low, but there is a minimal increase in pulse pressure.

Hemodynamic changes in postprandial state

Diabetes & Metabolism, 2006
Several experimental data suggest that single sugar intake may induce heart rate acceleration and blood pressure elevation as a result of sympathetic activation secondary to insulin response and from alterations in endothelial function due to activation of oxidative stress.

Hemodynamic Changes During Laparoscopic Cholecystectomy

Anesthesia & Analgesia, 1993
Hemodynamics during laparoscopic cholecystectomy under general anesthesia (isoflurane in N2O/O2 (50%)) were investigated in 15 nonobese ASA Class I patients by using invasive hemodynamic monitoring including a flow-directed pulmonary artery catheter. During surgery, intraabdominal pressure was maintained automatically at 14 mm Hg by a CO2 insufflator ...
