Background and Objective: surgery is a stressful experience and in open heart surgery, the patients are greatly faced with anxiety, which has been reduced by different approaches. This study aimed to investigate the effects of aromatherapy on anxiety level.

  Material and Methods: This blinded- randomized- controlled clinical trial was carried out on 90 patients divided into two groups of intervention and control. the patients of intervention group were asked to inhale two drops of lavender essential oil and those of control group two drops of distilled water poured on a gauze , for 20 minutes. In addition to measuring patients’ anxiety level by Spielberger questionnaire, we recorded their vital signs. Using SPSS 16 software, the data was described via mean, standard deviation and percent, and analyzed by using independent t-test, paired t-test, Chi Square and Covariance (0.05).

  Results: The mean age of intervention group was 50.49 ± 10.92 and control group was 50.13 ± 9.20. Anxiety score in intervention group was significantly decreased from 56.37±5.6 to 54.73±5.42 and in control group meaningfully reduced from 55.18±7.35 to 54.0±7.22 (p<0.05). The mean anxiety score in the intervention group was significantly higher than that of control group (p<0.05).

  Conclusion: Because anxiety reduction in aromatherapy group was more than control group it can be concluded that aromatherapy with lavender essential oil have significant effect in reducing anxiety and therefore can be used in clinical situations.

  Background and Objective: Coma due to brain injury is an important complication resulting in unconsciousness and reducing the capacity of responding to the environment. This study aimed at examining the effect of organized voice auditory stimulation, which was performed by a nurse, on the length of coma in the patients suffering from head injury.

  Material and Methods: This clinical-trial study was applied on 40 patients in the critical care unit of Panje Azar Hospital. The patients were randomly recruited to one of the two groups (each group 20 patients). The intervention group was stimulated by the voice of a male nurse. Hearing stimulation was conducted in the morning and night shift about 15 minutes each time for 10 days. The patient consciousness was measured by GCS scale and analyzed by ANOVA and t-test (P<0.05), using SPSS Soft ware.

  Results: ­ The average age of intervention and control group was 28.20 ± 11.49 and 27.8 ± 13.22, respectively. Before stimulation in the first day, there is no significant difference between the GCS of intervention group (5.95 ±0.68) and that of control (5.95 ± 0.64). The results indicate that the intervention group has become consciousness from the 5th day (GCS of 8.25 ± 1.19) and control group (GCS of 7.80 ± 1.96) from the 10th day.

  Conclusion: The study show that the auditory stimulation in the intervention group compared to control group gives rise to the improvement of ­the level of consciousness in comatose patients .

Background and Objective: Musculoskeletal disorders are the most common occupational complaints bringing about increased financial burden and reduced social productivity. This study aimed to determine the prevalence of musculoskeletal disorders and their relationship with psychosocial factors in the staff of organization.

Material and Methods: In this cross-sectional study, 675 staff of the organizations in Gorgan where selected via cluster & stratified sampling. The instruments Nordic standard questionnaire and job content including areas of job demands, decision latitude, job nature, social interaction with managers and colleagues. We analyzed the data by independent t-test, chi-square test and logistic regression (P&le0.05).

Results: Seventy-seven of participants (11.4%) suffer from neck pain, 39 (5.8%) from shoulder pain and 97 (14.4%) from back pain. Multivariate logistic regression showed a significant relationship between neck pain and the support given by supervisor and Colleagues. Respectively, Freedom of decision-making and support are the most common factors associated with shoulder and back pain.

Conclusion: Based on the results, the support of supervisor & Colleagues and the freedom of decision are the risk factors associated with musculoskeletal disorders.
