Background and Aim: Previous studies have shown that arterial hypertension induces cardiac hypertrophy and myocardial oxidative stress. The aim of the present study was to assess the effects of treatment by atorvastatin, as an antioxidant, to prevent myocardial oxidative stress and cardiac hypertrophy in hypertensive rats. Materials and Methods: In this experimental study, 20 male Wistar rats w...
Background and Objective: In order to determine the Hypoxemia and prognosis of patients with covid-19 hospitalized in the intensive care unit, reliable oxygen supply indicators are needed. In this situation, the examination of the percentage of arterial oxygen saturation (SaO2) and arterial oxygen pressure (PaO2), as well as their relationship, may be helpful. Materials and Methods: This des...
objective(s) calcium-channel blockers have an important role in the treatment of several cardiovascular disorders. derivatives of 1, 4-dihydropyridine are one of the most potent calcium antagonists. in this study four novel ', 4-dihydropyridine calcium channel blockers were synthesized and their hypotensive properties were investigated in male rats. materials and methods four 1, 4-dihydrop...
Aims: The present study was conducted with the aim of determining the effect of passive movements on hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse, and pulse pressure of patients under ventilation. Materials & Method: In this controlled clinical trial, 64 patients under ventilation in Kohgiluyeh and Boyer-Ahmad University of ...
Background & Aim : Endotracheal suctioning is one of the most frequently used methods for airway clearance in patients under mechanical ventilation. Chest physiotherapy techniques such as expiratory rib cage compression before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretions and improving alveolar ventilation. This study was carried out to...
background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...
Introduction: Massage of the limbs is a safe procedure that could have therapeutic effects and cause physical and psychological relaxation of patients in intensive care unit (ICU). Materials and Methods: This survey is a quaziexperimental study that assessas immediate effects of foot massage on patient’s vital signs in a general ICU. After a pilot study, a sample size of 50 patients was chosen....
The perpuse of this research is to determine the effect of foot massage on physiologic indicators including pulse, respiration and mean arterial pressure. The hypothesis of this research is that foot massage decreases the patient´s heart rate, respiratory rate and mean arterial pressure. This research is a quasiexperimental study and a self-control clinical trial with repeated measures in witch...
Background: To evaluate general anesthesia with sevoflurane vs spinal anesthesia with low dose lidocaine 5% onhemodynamics changes in patients undergoing hip fracture surgery.Methods: In this randomized double blind trial 100 patients (50 patients in each group) older than 60 years underhip surgery were randomized in general anesthesia with sevoflurane and spinal anesthesia with lidocaine 5%.He...
Magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. The antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. This study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...
