RESUMEN
BACKGROUND: Allergic rhinitis (AR) is one of the health problems in the world. It is necessary to develop new treatment procedure for control of this disease. The aim of this study was to assess the effect of Zofa (Nepeta bracteata Benth) on AR patients. MATERIALS AND METHODS: In this double-blind randomized clinical trial study, 71 patients (37 patients in treatment and 34 in placebo group) participated. In treatment group, N. bracteata syrup (NBS) was used for 4 weeks as three times a day. The efficacy of the drug regarding AR symptoms (rhinorrhea, sneezing, nasal obstruction, itchy nose, and ocular symptoms) were evaluated through a visual analog scale (VAS) by 0-10 before administration and at the end of the whole treatment period. The collected information was entered in the SPSS software (version 18) and was analyzed using the Fisher's exact test, Chi-square test, independent sample t-test, and paired sample test. RESULTS: The improvement of AR symptoms in the group receiving NBS was significantly higher compared to control group (4.73 ± 1.84 vs. 0.38 ± 2.06; P < 0.0001). Furthermore, the mean of total VAS before and after the treatment (in case group) was 7.10 ± 1.92 and 2.37 ± 1.76, respectively (P < 0.001). CONCLUSION: The results of this study indicate that N. bracteata has significant effects on improving the symptoms of AR. Hence, it can be a good alternative to AR symptoms relief.
RESUMEN
Nausea and vomiting are two of the most common complications of tonsillectomy in children. Administration of supplemental 80 % oxygen during surgery reduces the incidence of postoperative nausea and vomiting. We aimed to test the efficacy of supplemental 80 % oxygen during tonsillectomy on postoperative nausea and vomiting. In a randomized controlled trial in Shahid Mostafa Khomeini Hospital in Tehran, 102 children scheduled for tonsillectomy (± adenoidectomy) under general anesthesia were divided randomly in two groups according to percent of administered oxygen (group 1:30 % oxygen, group 2:80 % oxygen). The incidence of postoperative nausea and vomiting were assessed and compared in 0-2, 2-6 and 6-24 h after surgery. Incidence of post-tonsillectomy nausea and vomiting after 2, 2-6, and 6-24 h was 13.72, 1.96 and 1.96 % for group 1 and 3.92, 0 and 1.96 % in group 2, respectively. We found no statistically significant difference between two groups (P = 0.08) but 80 % oxygen was beneficial for reducing postoperative nausea and vomiting in the first 2 h after surgery in group 2.
