Résumé
Postoperative nausea is a common problem after general anesthesia, especially in ambulatory surgery. In ocular surgeries including strabismus surgery, intraocular pressure increase may lead to eye damage. Drug therapy has various side effects. The purpose of this study was to evaluate acupressure on nausea in patients undergoing strabismus surgery. In this double-blinded clinical trial, 60 patients undergoing strabismus surgery were allocated into intervention and control groups. In the intervention group, a sea-band was placed on the P6 point of patients' wrists 30 minutes before induction of anesthesia. In the control group, the sea-band was placed in the opposite position of the patients' wrists. Data were collected during six hours after surgery in the recovery room. Data were analyzed using Chi square, t-test, and Mann-Whitney tests. There were no differences in demographic and surgical characteristics between the two groups at baseline. The intensity of nausea in the recovery room [P=0.002] and six hours after surgery [P<0.001] were significantly less in the intervention group than the control group. Based on the findings of this study, acupressure decreases post operative nausea. Acupressure is a simple, noninvasive and cost-effective intervention which can be applied by nurses to prevent post operative nausea
Résumé
Hospitalization of patients in the intensive care unit of open heart surgery [ICUOH] is often stressful for patients' family carers. This study aimed to investigate the effectiveness of the informational support on anxiety among families of patients undergone open heart surgery. In this double-group randomized clinical trial, 64 family carers of patients undergone open heart surgery were selected using convenience sampling method and were randomly allocated into two intervention or control groups. The informational support consisted of holding the ICU orientation tours and educational sessions, and providing educational pamphlets and booklets. The members of the control group received routin information. The anxiety of the family carers was measured using the trait Spielberger anxiety questionnaire before surgery and in the day of discharge from the ICU. Independent and paired t-tests were used to analyze the data. According to the findings, there were no significant difference between the two groups regarding demographic charachteristics. At the baseline, the mean of anxiety scores were 47.9 +/- 11.5 and 49.2 +/- 11.5 in the control and intervetion groups, respectively. The anxiety scores diminished in both groups after the surgery, however, the difference was not statistically significant between the two groups [P=0.18]. For effective control of anxiety among family members of patients, both informational support and other supportive techniques such as psychological support and meeting other family needs should be considered
