Aims and Background: Surgery is a factor of anxiety which creates a physiological reaction in body. As a result of this physiological response of the body, breathing, heart rate and blood pressure would increase. The present study was done to evaluate the effect of wordless music on some physiological indices and anxiety of patients. Materials and Methods: This research is a randomized ...
Introduction: It is felt that there is an information void regarding the effect of macronutrients on cardiovascular responses such as cardiac output,heart rate,stroke volume,systolic blood pressure,diastolic blood pressure and mean arterial pressure, therefore, this study was designed to explore these effects at Shaheed Beheshti University in 2001. Materials & Methods: This clinical trial was ...
Background: Sinus surgeries are usually associated with bleeding, thus can result in hemodynamic instability. This study investigated the hemodynamic changes induced by remifentanil plus isoflurane administration in comparison with propofol plus remifentanil in patients undergoing sinus surgery.Methods: In this randomized clinical trial study, 96 patients were divided into two groups of isofl...
Background and purpose : Arterial blood gases ( Arterial blood gas [ABG] ) One of the most important Laboratory tests to determine the status PH the amount of oxygen and carbon dioxide blood levels of bicarbonate. Also, hemoglobin and serum lactate and electrolytes and also won the Test . Height and air pressure can vary on ABG and its surface, low pressure conditions at high altitude pilots pl...
Introduction: The Bed nucleus stria terminalis (BST) is a part of the limbic system. It was recently shown that chemical stimulation of the BST by L-glutamate elicited cardiovascular depressive responses. In the present study, we have investigated the possible cardiovascular role of the GABAergic receptors in BST by microinjection of its agonist and antagonists. Methods: Experiments were p...
Arterial drug concentration distribution determines local toxicity. The safety issues dealt with Drug-Eluting Stents (DESs) reveal the needs for investigation about the effective factors contributing to fluctuations in arterial drug uptake. The current study focused on the importance of hypertension as an important and controversial risk factor among researchers on the efficacy of Heparin-Eluti...
conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...
Background and Objective: Laryngoscopy and tracheal intubation can be achieved through both direct and video laryngoscopy. As video laryngoscopy complications still remain unknown among the elderly, this study was emerged to grasp the idea on the complications of two aforementioned methods among the elderly. Materials and Methods: In this clinical trial study, 60 patients over 65 years who h...
Background and Objective: The Ventral Tegmental Area is a part of the mesolimbic structure. In addition to its role in motivation, mood, cognition, schizophrenia, addiction and Parkinson’s disease, it is involved in the regulation of the cardiovascular system. The presence of cholinergic afferent fibers in the VTA has been demonstrated but there is no specific information about its role in card...
