Stress is applied to the collection of somatic, emotional and mental reaction, which can disturbed the equilibrium in human beings. One type of stress is work in dependent stress environment, which can affects on personnel due to its internal stressful factor. The object of this research is to investigate the rate of stress in operating room personnel and its relationship with some relevant factors. The present study has been done on 104 personnel of operating room in hospitals belong to the Gorgan Medical Sciences University. The tools for collection data were questionnaire, which contained demographical variables, physical and mental environment stress factors in operating room life stress scale. The results from this investigation indicated that 54.4% of all personals had a mild stress. The stress factors present in the operation room were inconvenient smells the highest with 76% uncooperated team work was the other factor with 29.7% and personnel equipment was (42.6%) it become clear from this investigation that there is a reverse between stress and demographical variables, of stress has a meaningful relationship with age (P=0.01) and years of service in the operation room which means as the age and working in the operation room increased the level of stress decreased. According to the results from this investigation it is suggested therefore to use the old and well-experienced staff to work in the operation room to avoid such problems.

Background & Objective: One of the post-operational problems in the cesarean-section is ileus symptoms and the starting point of taking the liquid diet. Some controversy are about this procedures. This study was done to evaluate the rate of ileus symptoms of women who are offered oral hydration shortly after cesarean delivery. Materials & Methods: This study involved 276 women delivered by cesarean under general anesthesia that had no previous cesarean or laparotomy and indisposing and their operations had not been exceeded 90 minutes. For these patients a liquid diet for every other day, partly 6 hours and others 12 hours after operation was started. The patients were examined at the time of starting diet and 6 hours later for bowel sound, nausea or vomiting, abdominal distention and gas passage. 138 women were assigned to each procedure. Results: Nausea or vomiting cases in the early fed group, were more than 12 hourly diets (2.2% versus no case) and (12.3% versus 10.9%) but the difference was not statistically significant. The bowel sound in the early fed group were less than 12 hourly starting the diets, (15.2% versus 12.3%) the difference was not statistically significant. The 6 hourly starting of liquid diet had a significant effect in speeding up bowel movements (P<0.05). Conclusion: Early oral hydration after cesarean was well tolerated and it was associated with rapid return of propulsive bowel movements, so to do, this results in better reply to the physiologic request of the patients.

Background&Objective: The main cause of the cardiovascular disease is atherosclerosis of coronary artery. One of theraputic methods of the disease is coronary artery bypass graft (CABG). One of the main complicatons of CABG is bleeding after grafting. Different methods and proposed for preventing or reducting the bleeding. The aim of this study is to evaluate the effects of tranexamic acid (TA) on reduction of bleeding after grafting.

Materials&Methods: This study was a randomized clinical trial. 100 patients conditated to CBG divided into 2 groups randomizely (50 for control and 50 for subject). TA was injected to subject group twice with the same dosage of 15 mg/kg: first during the operation and second after ending the cardiopulmunary pomp and neutralizing the theraputic effect of heparin by protamin. The same method was used for the control group, except normal saline was used instead of TA variations such as bleeding rate, PT, aPTT were tested after CABG. The extracted data was analysed by SPSS software.

Results: The range of ages was 28 to 75 years and the control and subject groups were distributed normally from age viewpoint. Bleeding rate after grafting in subject group was 335±45 ml and in control group was 490±81 ml. in case and control platelet count and hematocrit groups, were significant differences (P<0.05).

Conclusion: Using TA during and after CABG is suggested to control bleeding.

Background and Objective: Surgical wound infection is the most common complication following surgery. This study was done to determine the incidence risk factors of surgical wound infection following abdominal hysterectomy. Materials and Methods: This descriptive study was done on 400 patients who underwent abdominal hysterectomy in Babol, North of Iran, during 2008-10. Age, underlying disease, BMI, use of immunosuppressive drugs hospitalization period prior to surgery, shaving and bath time, prophylactic antibiotic, duration of surgery, diagnosis and pathology were recorded for each patient. Evidence of surgical location of infection including surgical discharge, erythema and dehiscence of surgical wound with and without fever during 10 days after surgery were recorded. Results: Surgical wound infection was seen in 26 patients (6.5%) following abdominal hysterectomy. Regression analysis determined, use of immune-suppressive (95% CI: 1.71-480.30, P=0.020, OR:28.70) and emergency operation (95% CI: 1.42-14.39, P=0.011, OR: 4.52), diabetes (95% CI: 1.23-11.26, P=0.020, OR:3.72) were risk factors for surgical wound infection. Conclusion: Immuno-suppressive agents, emergency operation and diabetes increased surgical wound infection in post- abdominal hysterectomy.
