ObjectivesIntravenous therapy is a complex procedure usually requiring the preparation of the medication in the clinical area before administration to the patient. Breaches in aseptic technique may result in microbial contaminations of vials which is a potential cause of different avoidable infections. We aimed to investigate the prevalence and pattern of microbial contamination of single- and multiple-dose vials in the largest pulmonary teaching hospital in Iran.MethodsIn a period of 2 months, opened single- and multiple-dose vials from different wards were sampled by a pharmacist. The name of the medication, ward, labeling of the vials, the date of opening, and storing temperature were recorded for each vial. Remained contents of each vial were cultured using appropriate bacterial and fungal growth media.ResultsMicrobial contamination was identified in 11 of 205 (5.36%) of vials. The highest contamination rate was 14.28% for vials used in interventional bronchoscopy unit. The most frequent contaminated medication was insulin. Gram-positive bacteria (81.82%) were more significantly involved than gram-negative ones (9.09%) and fungi (9.09%), with the highest frequency for Staphylococcus epidermidis.ConclusionsOur data demonstrate that repeated use of vials especially if basic sterility measures are disobeyed can cause microbial contamination of administered products to the patients. Infection preventionists are responsible to train health care workers regarding aseptic techniques and apply guidelines for aseptic handling of intravenous solutions. 相似文献

The clinical applications of benzodiazepines as anxiolytics are limited by their unwanted side effects. Therefore, the development of new pharmacological agents is well justified. Among medicinal plants, Coriandrum sativum L. has been recommended for relief of anxiety and insomnia in Iranian folk medicine. Nevertheless, no pharmacological studies have thus far evaluated its effects on central nervous system. Therefore, the aim of this study was to examine if the aqueous extract of Coriandrum sativum seed has anxiolytic effect in mice. Additionally, its effect on spontaneous activity and neuromuscular coordination were evaluated. The anxiolytic effect of aqueous extract (10, 25, 50, 100 mg/kg, i.p.) was examined in male albino mice using elevated plus-maze as an animal model of anxiety. The effects of the extract on spontaneous activity and neuromuscular coordination were assessed using Animex Activity Meter and rotarod, respectively. In the elevated plus-maze, aqueous extract at 100 mg/kg showed an anxiolytic effect by increasing the time spent on open arms and the percentage of open arm entries, compared to control group. Aqueous extract at 50, 100 and 500 mg/kg significantly reduced spontaneous activity and neuromuscular coordination, compared to control group. These results suggest that the aqueous extract of Coriandrum sativum seed has anxiolytic effect and may have potential sedative and muscle relaxant effects. 相似文献

Autologous nerve graft is still the treatment of choice in peripheral nerve injury when end-to-end nerve repair is not possible. The sciatic nerve is the most widely used nerve in rat experimental studies. To assess the possibility of using the rat median nerve as a delayed animal autologous nerve graft model in nerve regeneration studies, the effect of median nerve excision on the sciatic functional index (SFI) was evaluated. Thirty rats were distributed into three equal groups: in the sciatic and median nerve excision (SMNE) group, 10 mm of the right sciatic nerve was excised and 5 mm of both median nerves were excised a week later; in the median nerve excision (MNE) group, 5 mm of both median nerves were excised (both sciatic nerves remained intact); in the control group, no intervention was performed. SFI was calculated before and after each intervention. There was no significant difference between mean SFI values calculated before and after median nerve excision in SMNE (-86.8 versus -88.4, P = 0.61) and MNE groups (-3.9 versus -3.3, P = 0.93). Therefore, it may be suggested that median nerve excision does not affect SFI measurements in intact and/or completely injured sciatic nerve, which may propose the median nerve as an autologous donor nerve graft model in rats. 相似文献

OBJECTIVES: To investigate efficacy, safety, and impact on quality of sleep of desmopressin in the treatment of nocturia. METHODS: Adults aged > or =18 yr with nocturia (> or =2 voids/night) received desmopressin tablets (0.1, 0.2, or 0.4 mg) during a 3-wk dose-titration period. Patients should show sufficient response during the dose-titration period (> or =20% reduction in nocturnal diuresis) and a return of nocturnal diuresis to > or =80% of baseline levels during washout. Eligible patients then entered a 3-wk double-blind treatment period and received either desmopressin or placebo. RESULTS: 127 patients were randomised to either desmopressin (n=61) or placebo (n=66). Twenty (33%) desmopressin-treated patients compared with seven (11%) placebo-treated patients showed a clinical response, defined as a > or =50% reduction in the number of nocturnal voids compared with baseline (p=0.0014). Compared with placebo, desmopressin resulted in a significant reduction in the mean number of nocturnal voids (39% reduction with desmopressin vs. 15% with placebo; absolute difference -0.84, p<0.0001) and duration of the first sleep period (prolonged by 108 min with desmopressin vs. 41 min with placebo; p<0.0001). Quality of sleep was also improved with desmopressin versus placebo (statistically significant for one of the two parameters evaluated). Adverse events were mainly mild. CONCLUSIONS: Oral desmopressin tablets provide an effective and well-tolerated treatment for nocturia. Compared with placebo, nocturnal voiding frequency is reduced, duration of the first sleep period is increased, and sleep quality may be improved. 相似文献

The prevalence of Helicobacter pylori in children ranges from 10% to more than 80%. High prevalence occurs in developing countries, and after colonization it takes an extended period to be eradicated by the immune system. To evaluate the prevalence and age distribution of H. pylori infection in children in Shiraz (a city in the south of Iran), we collected 593 stool samples from children selected randomly from 5 age groups. Infection was determined based on antigen immunoassay in stool using the enzyme-linked immunosorbent assay method. The prevalence rates were 82%, 98%, 88%, 89%, and 57% in age groups of 9 months, and 2, 6, 10, and 15 years, respectively. There were no significant differences between the prevalence of H. pylori infection in the first 4 age groups (P > 0.05), but there was a significant decrease in the 15-year-old group (P < 0.05). The prevalence of H. pylori infection in the south of Iran is very high. The infection begins at infancy and remains high until late childhood. 相似文献
