  Background & Aim: Insertion of chest tubes is a necessary measurement in chest trauma. The trauma patients need specific skills for self-care. This study aimed to determine the effect of using supportive-educative system on self-care skills in trauma patients with chest drainage system .

  Methods & Materials: In this quasi-experimental study, 62 trauma patients with chest-tube were selected from three surgery wards of Besat hospital in Hamadan from December 2012 to May 2013. Two wards were randomly allocated into the experiment group (n=31) and one ward was allocated into the control group (n=31). Participants were selected using convenience sampling. The supportive-educative system was designed based on the patients’ needs and was implemented to the experimental group in three consecutive days. The study instruments included self-care needs assessment form and self-care skills checklist. Measurements were completed once the patients were admitted to the wards and three days later by an external observer. Data were analyzed using t-test, Chi-squared test, Mann-Whitney and Wilcoxon tests with a 95% confidence level in the SPSS-16 . 

  Results: There were no significant differences between the two groups in the study variables at baseline (P>0.05). Although self-care skills in both control (P<0.01) and experiment (P<0.001) groups were improved, using educative-supportive system led to better self-care skills in the intervention group in compare to the control group (P<0.001) .

  Conclusion: In general, self-care skills of patients with chest drainage system could be improved by supportive-educative system. The improvement in the control group can be attributed to self-care trainings conducted routinely by doctors and nurses .

Background & Aim: Changes in hemodynamic parameters can indicate the health status of individuals, and treatment measures cause changes in hemodynamic parameters, and affect the treatment process of patients. Different ways of distraction can have different effects. The aim of this study was to determine the effect of music distraction and movie-watching on hemodynamic parameters of patients undergoing extracorporeal lithotripsy.
Methods & Materials: A quasi-experimental study with a three-group, before and after design was performed on 90 patients undergoing extracorporeal lithotripsy in the lithotripsy unit of Ayatollah Kashani hospital affiliated to Shahrekord University of Medical Sciences in 2018. Patients were selected using the convenience sampling method and randomly allocated into three groups. The intervention included visual and auditory distraction. Data was collected before and after the intervention using demographic characteristics questionnaire, calibrated mercury blood pressure monitor, and pulse oximeter. Descriptive statistical tests (mean and standard deviation, percentage, frequency) and inferential tests (paired t-test, Pearson correlation coefficient and analysis of variance) through the SPSS software version 16 were used to analyze the data.
Results: Analysis of variance showed that the mean scores of systolic and diastolic blood pressure, pulse rate and oxygen saturation in the auditory, visual and control groups were not significantly different before the intervention (P>0.05). Also, the mean scores of these variables in auditory, visual and control groups were not significantly different after the intervention (P>0.05). Paired t-test also showed the mean scores of pulse rate (P=0.133), systolic (P=0.159) and diastolic blood pressure (P=0.413), and oxygen saturation (P=0.083) did not have significant differences after the intervention compared to before the intervention between the groups.
Conclusion: According to the results, music and movie-watching did not have a significant effect on hemodynamic parameters of patients undergoing lithotripsy. Due to the lack of confirmatory studies, further research is needed on lithotripsy patients.
