BACKGROUND Hypertension is a disease state characterized by increased blood pressure (BP) associated with hemodynamic abnormalities, including elevated systemic vascular resistance index (SVRI); and altered cardiac index (CI). The objective of this study was to use noninvasive impedance cardiography (ICG) to evaluate hemodynamic characteristics of subjects with and without hypertension. METHO...
Background & Aim: Physiologic signs of anxiety usually change hemodynamic variables in patients undergoing heart catheterization. This study carried out to determine the effect of Orientation Program on hemodynamic variables in patient undergoing heart catheterization. Methods & Materials: In this experimental study, 60 patients undergoing heart catheterization were randomly assigned to eith...
conclusions fentanyl and fentanyl plus lidocaine effectively decreased the hemodynamic response to tracheal intubation, however, neither fentanyl nor fentanyl plus lidocaine, could inhibit all hemodynamic responses, moreover fentanyl plus lidocaine was not more effective than fentanyl alone. background induction of anesthesia and endotracheal intubation often creates a period of hemodynamic ins...
Introduction: Laryngoscopy and tracheal intubation necessitate to start a surgery and induction of general anesthesia as well as the maintenance of the air way and to provide ventilation. However, Laryngoscopy and tracheal intubation may lead to hemodynamic response that appear with the symptoms of hypertension tachycardia, arrhythmia and myocardial ischemia and results in myocardial infarction...
Introduction & Objective: ECT is an inevitable therapy for many of psychiatric patients. During ECT severe hemodynamic changes occur which may cause dangerous cardiovascular complications especially in elderly patients with cardiac disease and may lead to arrhythmia,ischemia and myocardial infarction. The purpose of this study was to show the effect of clonidin and propranolol on the preventi...
Opioids are well known to cause cardiovascular depression. The aim of the present investigation was to determine whether an interaction of opioid derivatives with catecholamines might be involved in these hemodynamic alterations. Six comatose patients were enrolled into a prospective, nonrandomized pilot trial. All patients first received a continuous i.v. infusion of dobutamine (10 microgram. ...
