Aim and Background: Now, 95 % of the pregnant experience regional anesthesia. Neuro-axial technique-induced sympathic block may result in hypotension in the mothers and consequently can affect the blood uterus. Different findings regarding the effects of prophylactic hydration prevention of maternal hypotension , the decision to study in this field. Materials and Methods: The study is a randomi...
در این مطالعه به بررسی تغییرات همودینامیک ناشی از مصرف رمی فنتانیل بعلاوه پروپوفول در قیاس با رمی فنتانیل بعلاوه ایزوفلوران در بیماران تحت جراحی اندوسکوپیک سینوس در بیمارستان های آموزشی دانشگاه آزاد در سال 1389 پرداختیم.روش مطالعه: این مطالعه به صورت یک بررسی مداخله ای (interventional) از نوع کارآزمایی بالینی تصادفی (randomized clinical trial) انجام شده است. 96 بیمار به صورت تصادفی در یکی از دو...
Background and Aim: Intratracheal suctioning is a standard method of nursing care for intubated patients with the aim of cleaning airway for good oxygenation. The aim of this study was to evaluate the effects of intratracheal suctioning on blood pressure, heart rate, and arterial oxygen saturation. Materials and Methods: This was a semi-experimental research in which the patients admitted t...
Introduction: World Health Organization (WHO) introduced hypertension as an epidemic in developing countries. However, hypertension is adequately controlled in only 12.5% of patients. The aim of this study was to evaluate the relationship between Ramadan fasting and mean arterial pressure (MAP). Methods: This clinical, observational study was carried out at Medical O.P.D of Jinnah Medical Coll...
Background and purpose: Increased pressure in the pulmonary circulation is of the major factors causing cardiac disorders in patients with thalassemia. The aim of this study was to investigate the relationship between splenectomy and pulmonary arterial pressure in individuals with beta- thalassemia major. Materials and methods: A cross-sectional study was carried out in patients with beta- t...
Background & Objective : Several indices have been introduced to estimate arterial stiffness that based on changes in brachial blood pressure. But because of the error resulted by the substitution of brachial blood pressure instead of the other central arteries, such as carotid, it will be very important to present elastic parameter based on the mechanical models without any emphasis on brach...
introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...
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...
Oxygen is an essential part of the most important metabolic pathways in aerobic organisms. Oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. Traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. Increasing intra-abdominal pressure (IAP) has been shown to reduce liver b...
