Background & Objectives: It is estimated that 4-10% of diabetic patients suffer from foot ulcer. About one in five people with diabetes enters hospital for foot problems. Regarding the importance of education for these patients, the present research was conducted to evaluate the effect of education on foot care among diabetic patients referring to Ardabil Buali hospital.

 Methods: From the diabetic patients referring to Buali hospital (diabetes center) 120 patients admitted for the first time, who had had no past training about diabetes, were selected. Each patient was asked to fill out a questionnaire on his reference to the hospital. The questionnaire had 38 questions, the first 8 of which were about the demographic status and the illness itself and the rest of them concerned priniciples of foot care. Following this, these diabetic patients participated in public classes in the center, and a month later they filled the questionnaire again. Finally their knowledge before and ofter the education period was compared using statistical analyses.

 Results: The level of knowledge of 73.33% of the subjects before education was medium whereas following the education this rose to 86.67%. Comparing the level of knowledge of patients before and after education using t-test indicated that the level of knowledge after education is significantly higher than before (p<0.001).

 Conclusion: with regard to the significant difference in knowledge of diabetic patients before and after education, it can be concluded that educational classes of diabetic center can improve the knowledge of patients about foot care. So they are strongly recommended to be held for all these patients.

  Background & Objective: Postoperative nausea and vomiting is the most common complication of anesthesia with an approximate prevalence of 30% up to 70% (in high risk patients). In recent years several articles have investigated the effects of antiemetic and anesthetic drugs on postoperative nausea and vomiting, but the nonpharmacological methods, which are cost-effective and have no side effects, are rare. Since it is essential for patients to be on fast before surgeries which require general anesthesia, occurrence of dehydration and extra cellular fluid volume deficit and subsequently nausea and vomiting are expected and anticipated. Thus in this study the effect of preoperative intravenous fluid on postoperative nausea and vomiting was explored.

  Methods: This clinical trial study was performed in two experimental and control groups, with 30 subjects in each. Experimental group were given a 1- liter bolus of intravenous normal saline preoperatively in addition to routine IV fluid. Finally the incidence of postoperative nausea and vomiting was observed and compared between two groups.

  Results : According to statistical tests, the differences between age, preoperative and postoperative NPO duration, use of antiemetics and the duration of hospitalization in two groups were statistically significant but the differences between other demographic variables and the volume of intraoperative intravenous fluid received during the surgery were not. Results showed that experimental group had significantly lower incidence of nausea and vomiting (20% and 10% respectively) in comparison with control group (50%). According to chi-square test, the rate of postoperative nausea and vomiting was significantly different in two groups. (p=0.015 and p=0.001 respectively) Also, preoperative NPO duration had significant relationship with postoperative vomiting (p= 0.05).

  Conclusion: Regarding the positive effect of intravenous fluid therapy on postoperative nausea and vomiting as a cost effective and harmless method in surgery, its use is recommended.�
