Introduction: Admission of a family member to hospital would cause stress on other family members also. One of the most stressful treatment interventions imposing high level of anxiety to the families of patients is when the patients are undergoing a surgery, especially a cardiac surgery. So, we decided to investigate whether recommended Azkar could reduce stress, anxiety, and depression in families of the patients. Materials and Methods: This study is a quasi-experimental study conducted on 120 immediate relatives of patients undergoing a cardiac surgery. Families of patients undergoing open heart surgery were randomly divided into two groups of study and control. The Depression, Anxiety, and Stress Scales (DASS 21) questionnaires were completed by both groups. Then, some explanations about how to use recommended prayers were given to the study group, and an hour later, the questionnaires were completed again. The data were analyzed by SPSS. P < 0.05 were considered significant. Results: Stress, anxiety, and depression showed a significant difference in the study group before and after intervention. Similarly, there was a significant difference in the mean scores of anxiety, stress, and depression in the study and control groups after intervention. Conclusions: Findings of the present study showed that recommended religious prayers can significantly reduce anxiety, depression, and stress of families of the patients undergoing open heart surgery.

BACKGROUND: Since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in NICU. This study aimed to investigate the effects of prone and supine positions on oxygenation (SPO2) in premature infants under mechanical ventilation and comparing infants’ oxygenation in the two positions. METHODS: In across over non randomized clinical trial study, 32 preterm infants under mechanical ventilation who had inclusion criteria were enrolled in simple convenient method. Firstly, they were placed in supine position for 120 minutes and further in prone position for 120 minutes .Their SPO2 were monitored by pulse oximeter continuously and was recorded every minute. Data analysis was done using Software SPSS15 by ANOVA test and post hoc test. RESULTS: The data showed that during 120 minutes of exposure of infants in each position there were no significant changes in SPO2. In addition, the SPO2 levels in the prone position were significantly higher than the SPO2 levels in the supine position from 15th minute to 120th minute (to the end). CONCLUSIONS: Neonatal positioning in prone position is a simple, non-invasive, and free of charge method that could lead to improve oxygenation in infants undergoing mechanical ventilation.
