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...
Introduction: Intensive care unit is one of stressful wards for patients and stress creates some alterations in physiologic indicators of patients. So it is necessary to use a low expense and comforting method to stabilize physiologic indicators. The purpose of the present research is to determine the effect of foot massage on physiologic indicators including pulse, respiration, mean arterial p...
Background: Physical activity has been recognized as one of the non-pharmacological methods in the treatment of hypertensive disorders. This study aims to compare the effects of aerobic exercise performed and alternative (AI) and constant intensities (CI) in hypertensive individuals. Methods: In this semi-experimental study, subjects were 20 hypertensive women who were asked to fill in the q...
Background: Entanglement of the umbilical cord around fetal neck has been reported to be associated with birth asphyxia. On the other hand, current evidence suggests that umbilical arterial pH analysis provides the most sensitive reflection of birth asphyxia. In this study we aimed to evaluate and compare the umbilical arterial hydrogen-ion concentration (pH) and to analyze the blood gases of n...
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-dihydropyr...

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...
