Introduction: Laser beam due to finest of incision and reduction of postoperative complication, facilitates airway surgery, but at the same time it increases the danger or firing and the airway management and protection becomes difficult during anesthesia. In this study, two general anesthesia methods (Intermittent Apneic Technique And Continuous Controlled Ventilation With Enveloped Endotracheal Tube) have been compared with each other mater.

Materials and methods: two groups, each consist of 25 patients 10 to 60 years old, and ASA I-II class and below 100kg weight who have been candidate for laser therapy, were given two mentioned methods of anesthesia. All patients were suffering from subglotic stenosis, vocal cord nodules, papillomatosis and oropharyngeal obstruction. Induction and maintenance of anesthesia, and monitoring during surgery (EGG, PETCO2, SaPo2, BP, PR) in both groups were the same.

Results: Homodynamic stability in the both groups were the same and there was no hypoxia and dysrhythmia. In apneic technique group, most of the surgeries needed 2-3 time of apnea, and each apnea duration was 2-4 minutes, without any hypercaphic (Peteco 2>47 mmHg) and hypoxic (Spo2<90 percent) state and duration of laser surgery was about 9-10 minutes. More satisfaction was gained with apneic technique because of having a better surgery filed. All the patients had no recall at the end of anesthesia and patietn's expenses were much lower with no danger of firing.

Conclusion: It has been concluded that intermittent apneic technique in upper airway laser therapy is a better technique of anesthesia.

Background: The kidney is a complex and vital organ, regulating the electrolyte and fluid status of the human body. In clients with a chronic disease, such as end-stage renal disease, functioning status and hematologic indexes are different than among the general population. Electrolyte and hematologic changes may induce many illnesses for such patients. The purpose of this study is to determine the effects of applying the continuous hemodialysis (HD) the blood test results of HD patients.

Methods: This quasi-experimental, before-after study included 38 HD patients from Hamedan, Iran in 2005. Subjects were selected using simple randomized sampling and were assigned to one group for the purpose of this research and investigated over a period of six months. Data collection tools included demographic questionnaire and control check lists. The first phase of the research involved orientation of the control group, which was limited to completion of the questionnaires and control check lists. Immediately after, the same patients became the case group, upon which continuous HD was applied and hemoglobin, hematocrit, blood urea nitrogen (BUN), potassium, sodium, and albumin tests were performed. Statistical analysis of the data employed SPSS (version 13), descriptive statistics, paired t-test and the Friedman test.

Results: In this group, 47.2% of the subjects were male and 52.8% female. Data analysis shows that, using repeated measurement ANOVA test, a significant relationship between application of the continuous HD and improvement in hemoglobin, hematocrit, BUN, potassium, sodium, and albumin levels (p<0.05).

 conclusion: Application of continuous HD causes a significant improvement in the blood test results of HD patients. We recommend that continuous HD be used, whenever appropriate, to resolve the common causes of complications in HD clients, including abnormal levels of electrolytes, especially potassium and phosphorus, as well as BUN and creatinine.

800x600 Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Obesity is a major health problem all around the world. On the other hand, few people, especially women, are physically active to the levels recommended by Healthy People 2010 web site managed by the U.S. Department of Health and Human Services. The objective of this study was to compare the potential effects of intermittent and continuous exercise programs combined with concurrent calorie restriction diets on lipid profile and fasting blood sugar in overweight and obese females.
Methods : Forty-five women with a sedentary life style and a BMI greater than 25 kg/m², were randomly assigned to one of the three groups (15 subjects in each group): a) 40 minutes of medium-intensity intermittent exercise (64-76% of maximal heart rate), 3 bouts per day for 5 days a week, b) a single bout of a 40-minute continuous exercise per day for 5 days a week, C) the non-exercising control group. A self-monitored calorie restricted diet was recommended to all participants by a dietitian. The lipid profile, fasting blood sugar and blood pressure of all participants were assessed at baseline and 12 weeks after the intervention period.
Results : After the intervention, there were no significant differences among the groups in terms of lipid profile [cholesterol (P=0.94), triglyceride (P=0.62)] fasting blood sugar (P=0.054), systolic blood pressure (P=0.84) or diastolic blood pressure (P=0.30).
Conclusion: There seems to be no significant differences between short term continuous and intermittent aerobic exercise programs in improving lipid profile, fasting blood sugar or blood pressure both in overweight and obese women.
