Background & Objectives: Dysmenorrhea is a common complaint among women, which is occasionally accompanied by gastro-intestinal problems. This study was designed to consider the therapeutical effects of vitamin E on gastro-intestinal symptoms such as nausea, vomiting and diarrhea due to primary dysmenorrhea.

 Methods: This was an experimental randomized study. A questionnaire was given to three hundred girl students suffering from primary dysmenorrhea. Then 128 girls who had gastro- intestinal symptoms accompyning dysmenorrhea entered the study. 69 subjects were assigned to case group and 59 to control group. From two days before the period until three days after it, four pills of vitamin E (400IU) daily were given to the case group and four chewing placebo were given to the control group as well, for four months. The data were analyzed by SPSS using Chi-square test.

 Results: The findings showed no significant difference between the two groups in terms of gastro-intestinal symptoms after two months of treatment. But after four months of treatment there was a significant difference in the gastro-intestinal symptoms between the two groups (p=0.001).

 Conclusions: Vitamin E is effective to be used after the second month of treatment to treat the gastro-intestinal symptoms in girls with primary dysmenorrhea.

  Background & Objectives: Postoperative nausea and vomiting are among the main complication after anesthesia and various methods are used for the prevention of this complication. In this study, the effect of the pre induction use of 10mg Metoclopramide’ 8 mg Dexamethasone and the combination of the both, on decreasing in the rate of nausea and vomiting after cataract surgery in intravenous anesthesia is compared with placebo.

  Methods: In this double blind clinical trial, one hundred patients of cataract surgery who are appropriate for this study were, randomly divided in to four groups. In the group of placebo (P), 2cc normal saline, in group (M), 10mg metoclopramide, in group (D), 8mg Dexamethasone, and in group (M+D), 10mg metoclopramide and 8 mg Dexamethasone, one minute before the induction of anesthesia was injected. Patients were received the anesthetic drugs in the sameway and after the tracheal intubation infusion of propofol was started. After the end of surgical operation, the appearance of nausea and vomiting in the recovery room and also 6 and 24 hours after the surgery are recorded in the patients' information forms. Finally the data were analysed by statistical software of SPSS and the statistical tests.

  Results: After the use of these drugs, the rate of nausea in the recovery room decreased from 44% in placebo to 20% in metoclopromide group, 16% in Dexamethasone group, and 8% in combination of metoclopromide and Dexamethasone and the rate of vomiting decreased from 20% in placebo group to 4% in metoclopromide group, 4% in Dexamethasone group, and 0% in combination of these two drugs, both the nausea and vomiting the effect of combination of metoclopromide and Dexamethasone in decreasing of postoperative mausea and vomiting was significant (P<0.05). The 24 hour following of nausea and vomiting, also had the same results.

  Conclusion: With regrard to the results of this study, implication of the combination of 10mg metoclopromide and 8mg Dexamethasone before the induction of anesthesia remarkably decreased the rate of postoperative nausea and vomiting and is useful for the high risk groups for this complication especially in out patient surgery.

  Background & Objectives : nausea and vomiting is one the most common problem during pregnancy. There are several reports about treating effect of acupressure for nausea and vomiting. Our propose was to investigate of p₆ acupressure in reducing and relieving of symptoms of nausea and vomiting during pregnancy.

  Methods : A single blind clinical trial has been conducted in order to examine the effect of P₆ acupressure on nausea and vomiting of pregnancy in women referring to health center of Ardebil at 2005. 75 women complained of nausea and vomiting after being matched on the basis of the intensity of nausea and vomiting and pregnancy period were invited to participate in the study. Subjects were divided into three groups of treatment, placebo, and control (25 persons in each group), accidentally. Women in treatment group use acupressure wristbands with pressure to P₆ acu-point, in placebo group use acupressure wristbands without pressure to P₆ and control with no intervention. The symptoms were evaluated for 6 days and twice daily using a questionnaire inspired by Rhodes Inventory of Nausea and Vomiting. In the first 3 days all there groups equally filled the questionnaire and in the second 3days the treatment and placebo groups filled there out. Data of frequency, duration, and severity of nausea and frequency of vomiting were analyzed by Analysis of variance and Wilcoxon means were compared with Tukey and Kruskal-wallis tests.

  Results: Analysis revealed that the participants in three groups didn't have significant differences in regard to age (treatment 24.3 ±3.9 , placebo 24.9 ±4.3 , control 25.4 ± 3.3 year), gestational age (treatment 12.4 ±2.8 , placebo 12.9 ± 3.1, control 12.4 ±2.8 week) number of parity (treatment 1.7, placebo 1.6, control 1.4 times) education, job, number of pregnancy. The mean score of nausea severity decreased from 25.1 ±18.6 to 12.0 ±11.0 in treatment group, from 22.8 ± 14.6 to 16.1 ±12.31 in placebo group but increased from 16.3 ± 7.48to 17.5 ±8.92 in control group. The mean of vomiting frequency also decreased from 3.1 ± 3.33 to 1.5 ±1.66 and from 3.1 ± 4.30 to 1.9 ±3.68 in treatment and placebo group, respectively but its value changed from 1.2 ± 2.2 to 1.4 ± 1.4 in control group. Differences between pre-treatment and treatment period of nausea and vomiting symptoms was not significant in treatment group than placebo groups (p<0.043) and it was more in the placebo compared to control group (p<0.009). Comparing of means in treatment and placebo groups showed significant difference in nausea frequency and severity but not significant differences in duration of nausea and frequency of vomiting.

  Conclusion: P₆ acupressure wristband is effective in the treatment compared to control and placebo for reduction of severity, duration and frequency of nausea and frequency of vomiting. The wristband without pressure to P₆ acu-point also is affected in reducing nausea and vomiting symptoms but its effect is lower than P₆ wristband.

  Background & Objective: With consideration the daily increased development of outpatient surgeries and high rate of these operations in elderly patients, rapid and safe recovery of patients for coming back to daily life is necessary. In this clinical trial study recovery time and nausea and vomiting after the use of two rapid-onset narcotic, alfentanil and remifentanil in elderly patients has been compared.

  Methods: In this double-blind clinical trial 40 elderly patients (age above 65) candidated to cataract surgery with general anesthesia were studied. The patients were divided randomly into two groups and for first group alfentanil was injected 10 m g/kg and for second group remifentanil 0.5 m g/kg during 30 seconds one minute before induction. Both two groups were under general anesthesia with same method and during the anesthesia first group took infusion of alfentanil 1 m g/kg/min and second group remifentanil 0.1 m g/kg/min. At the end of surgery the time intervals between end of anesthesia drug adminstration and autonomic respiration, eyes opening with stimulation, verbal response and discharge of recovery room, also the incidence of complications related to narcotic drugs especially nausea and vomiting were recorded. The data were analyzed in SPSS software using descriptive and analytical statistics as T-test, chi square and ANOVA.

  Results: The time of autonomic respiration in alfentanil group was 2 minutes and in remifentanil group 3.3 minutes,this time in alfentanil groupe1.3 minutes shorter but the difference was not significant. The time of eyes opening with stimulation, verbal response and discharge of recovery room were not significantly different. During recovery incidence of nausea and vomiting in remifentanil group (30% of patients) was significantly more than alfentanil group (5% of patients) (P<0.05).

  Conclusion: The time of recovery between alfentanil and remifentanil group was not significantly different, but incidence of nausea and vomiting in remifentanil group was higher than alfentanil group significantly.
