ABSTRACT
Background and Aim: bronchoscopy is a stressful procedure. Increased anxiety raises oxygen demand during bronchoscopy and affects cardiac output and blood pressure. The purpose of this study was to evaluate the effect of distraction by audiovisual folk music on hemodynamic parameters in patients undergoing bronchoscopy
Materials and Methods: this randomized clinical trial was performed in Imam Ali Hospital in Zahedan. We used convenience sampling method for three-month from July to September 2015 and sixty patients who had been scheduled for bronchoscopy were randomly divided into control [n= 30] and experimental [n = 30] groups. Demographic information forms and hemodynamic parameters record chart were used for data collection. During bronchoscopy, every patient listened to an audiovisual folk music which had been selected by himself. The control group received routine care. Using SPSS software version 21, data were analyzed by chi-square [X[2]], independent t-test, paired t-test and repeated measures analysis of variance
Results: the results showed that two groups had statistically significant difference in relation to hemodynamic parameters during and after intervention [p=0.0001]. The pattern of decline was not similar in both groups. Distraction by audiovisual folk music led to decreased heart rate and blood pressure, and also increased oxygen saturation in the experimental group
Conclusion: audiovisual folk music selected by every patient, during bronchoscopy resulted in the improvement of the hemodynamic parameters. Therefore, use of this method is recommended during invasive diagnostic and treatment procedure especially bronchoscopy
ABSTRACT
Nowadays, anemia is one of the most common but forgotten nutritional deficiencies in the world. More than half of pregnant women and one third of non-pregnant women of fertile age are suffering from anemia. This study was undertaken to determine the prevalence of iron-deficiency anemia in the pregnant women referring to Health Centers in Zahedan. In this descriptive study, 287 pregnant women who were at the 9th month of pregnancy and referred to 5 Health Centers in Zahedan participated in the study. Data was gathered by a 17-item questionnaire including demographic data and related information on pregnancy. To determine hemoglobin [Hb] and ferritin, a blood sample was taken form the subjects too. In order to examine the relationship among variables, X[2] and correlational tests were used. An alpha level of <0.05 was considered significant. The results showed that 12.9% of the subjects had iron deficiency anemia with Hb values under 10.5 g/dl and 42.2% of them had iron deficiency amenia with ferritin values under 12 mg/L. There was a significant statistical relationship between ferritin levels and iron consumption during pregnancy [p<0.001]. Considering the high prevalence of iron-deficiency anemia in this research, that will gives rise to LBW newborns, premature labors, fetal demise, post partum hemorrhage and fetal distress, it is necessary to offer unremitting and subtle care during pregnancy, teach pregnant women on the subject and provide sufficient micro nutrients to them
