Introduction: Increased serum lactate is seen during surgery due to tissue hypoxia. There have been reports of propofol infusion syndrome due to long-term use of this drug, especially in intensive care patients. This study was conducted to evaluate the factors affecting serum lactate levels in patients under general anesthesia with propofol in spine surgery. Methods: In a cross-sectional study...
Introduction: One of the complications of laryngoscopy and endotracheal intubation is sympathetic stimulation with hemodynamic changes that are always tried to be avoided by anesthesiologists. The aim of this study is to review and compare hemodynamic changes caused by both conventional and video laryngoscopy. Methods: In this clinical trial performed in 2015 in the Birjand-based Imam Reza Hosp...
Introduction: The bed nucleus stria terminalis (BST) is a part of the limbic system, which plays a role in regulation of heart beat and blood circulation. It was recently shown that microinjection of L-glutamate in the BST elicits cardiovascular depressive, but the role of glutamate receptor subtypes has not been investigated yet. In this study, the role of glutamate receptor subgroups in regul...
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...
Introduction: The present research aimed to review the effect of a 15-day cinnamon supplementation on hematocrit and mean arterial blood pressure in response to one session aerobic exercise. Materials & Methods: In this semi experimental study, 24 male voluntary staff of Fars Islamic Azad university, science research branch by getting testimonial and university ethics committee selected as s...
background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...
conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...
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: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...
Background & Aim: Endotracheal suctioning (ETS) is a common invasive nursing procedure. Hemodynamic parameters changes during and after the procedure. If appropriate strategies do not be applied during the ETS, hemodynamic changes can be significant and life threatening in critically ill patients. The purpose of this study was to assess the effect of education of endotracheal suctioning on pati...
