BACKGROUND: Although rarely life-threatening, postoperative vomiting (POV) is a distressing complication. The incidence of POV ranges from 34 to 90% in children undergoing strabismus surgery when antiemetics are not administered prophylactically. METHODS: In this study, a cost-consequence analysis (CCA) is used to estimate the economic benefit of ondansetron and dimenhydrinate as antiemetics administered prophylactically in children undergoing strabismus surgery. This retrospective study was conducted at The Hospital for Sick Children based on a review of 70 charts. RESULTS: Ondansetron was more effective with 45.3 POV-free patients (PFP) in an adjusted cohort of 100, while dimenhydrinate resulted in 38.2 PFP in an adjusted cohort of 100. The costs were significantly different between the two groups, CAD dollars 185.90 (+/-26.37, 95% CI, CAD dollars 173,89; CAD dollars 197.90) and CAD dollars 232.90 (+/-CAD dollars 66.84, 95% CI, CAD dollars 198.53; CAD dollars 267.27) per patient for ondansetron and dimenhydrinate, respectively. The length of stay in the postanesthetic care unit (PACU) represented over 97% of total costs, and the mean lengths of stay in the PACU for ondansetron and dimenhydrinate were significantly different, 3.43 and 4.41 h, respectively. CONCLUSION: This study should serve as a pilot for a large-scale investigation on the correlation between the length of stay in the PACU and the antiemetic agent used. 相似文献

OBJECTIVE: Axillary padding without drainage appeared to be a valuable alternative technique to vacuum drainage. The technique employs local muscles or the axillary aponeurosis for padding. We report here the clinical evaluation of muscular padding without drainage. The analysis of these results prompted us to also do a literature search for other alternatives aimed at reducing morbidity due to vacuum drainage. PATIENTS AND METHODS: Muscular padding was prospectively performed by 8 different surgeons on a total of 152 patients at the Centre Rene-Huguenin (Saint-Cloud, France). Follow-up has attained 3.5 years. A comparative assessment of pain was conducted in 30 patients operated on with vacuum drainage. RESULTS: This technique is easy to learn and reproducible. It facilitates post-operative follow-up, always allowing discharge at the 2nd or 3rd post-operative day without any home nursing. The late sequels are not increased. In contrast, pain was twice more intense during the first post-operative weeks compared with vacuum drainage, and the seroma rate was also increased. DISCUSSION AND CONCLUSION: Despite good efficacy, this worsening of pain is a major obstacle to the routine use of muscular padding. A technical improvement has been published very recently where the axillary aponeurosis was used to pad the axilla. It seems to be equally efficient but less painful than muscular padding. This technique is under clinical evaluation and could appear as a valuable option to vacuum drainage. Other alternatives are discussed. Most studies lack a direct comparison with vacuum drainage and a satisfactory evaluation of quality of life is also omitted. New studies with quality of life scales are ongoing. They should allow us to choose options that take this aspect into account in the future. 相似文献

OBJECTIVE: To determine whether children's food consumption is increased by the size of the group of children in which they are eating. DESIGN: Crossover study. SETTING: University based preschool. PARTICIPANTS: 54 children, aged 2.5-6.5 years. INTERVENTIONS: Each child ate a standardised snack in a group of three children, and in a group of nine children. MAIN OUTCOME MEASURES: Amount each individual child consumed, in grams. RESULTS: Amount eaten and snack duration were correlated (r = 0.71). The association between group size and amount eaten differed in the short (<11.4 min) versus the long (> or =11.4 min) snacks (p = 0.02 for the interaction between group size and snack duration). During short snacks, there was no effect of group size on amount eaten (16.7 (SD 11) g eaten in small groups vs 15.1 (6.6) g eaten in large groups, p = 0.42). During long snacks, large group size increased the amount eaten (34.5 (16) vs 26.5 (13.8), p = 0.02). The group size effect was partially explained by a shorter latency to begin eating, a faster eating rate and reduced social interaction in larger groups. CONCLUSIONS: Children consumed 30% more food when eating in a group of nine children than when eating in a group of three children during longer snacks. Social facilitation of food consumption operates in preschool-aged children. The group size effect merits consideration in creating eating behaviour interventions. 相似文献

PURPOSE: To study interactions between disease-free survival (DFS) and four components of the plasminogen activator system: urokinase-type plasminogen activator (uPA), its two inhibitors (PAI-1 and PAI-2), and its membrane receptor uPAR. PATIENTS AND METHODS: We conducted a retrospective study of 499 primary breast cancer patients (median follow-up, 6 years). uPA, PAI-1, and PAI-2 were determined on cytosols and uPAR on solubilized pellets, using enzyme-linked immunoadsorbent assay kits (American Diagnostica, Greenwich, CT). Classical univariate and multivariate statistical methods were used together with multiple correspondence analysis to graphically examine interactions between the variables and outcome. RESULTS: By univariate analysis, higher uPA and PAI-1 values were significantly related to shorter DFS (P =.002; P <.00002). PAI-2 was not significantly related to DFS, although patients with high and very low PAI-2 values had a longer DFS. Multiple correspondence analysis showed the parallel impact of uPA and PAI-1 on outcome, and the clearly different behavior of PAI-2 compared with PAI-1. The prognostic contribution of uPAR seemed weak by both methods. A dissemination risk index [uPA x PAI-1/(PAI-2 + 1)], taking into account the modulation of uPA proteolytic activity by the ratio of its two inhibitors, was then tested. Dissemination risk index was selected as an independent variable in the Cox model in the overall population (P <.000001) and in node-positive patients (P <.00001). It was the only variable selected in node-negative patients (P =. 003). CONCLUSION: A dissemination risk index determined on primary tumor and taking into account the different effects of PAI-1 and PAI-2 on uPA can be of major help in clinical management of breast cancer, particularly in node-negative patients. 相似文献

Between May 1986 and May 1987, 35 primary noninflammatory breast carcinomas (T3N0-N1M0) were studied by means of DNA flow cytometry (FCM-DNA) before and after each of three courses of preoperative chemotherapy (doxorubicin, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil) to assess initial nuclear DNA content, initial S-phase fraction (SPF), and the impact of chemotherapy on these parameters. Correlations were sought with objective regression and short-term follow-up. Four sequential cytopunctures were performed for cytologic examination and FCM-DNA analyses. Ten tumors were diploid and 25 aneuploid. No significant changes in FCM-DNA parameters during chemotherapy were observed in diploid tumors, and no regression was seen in nine of the ten cases. Among the 25 aneuploid tumors, 10 showed changes in DNA content and/or kinetic parameters. A significant correlation was observed between objective regression and initial FCM-DNA content (P = 0.008), initial SPF (P = 0.004), and changes in FCM-DNA patterns observed during chemotherapy (P = 0.00005). During the follow-up period (range, 27 to 41 months), 13 patients had relapses. Patients with aneuploid tumors were more likely to have relapses (n = 11) than patients with diploid tumors (n = 2), and patients with high SPF were more likely to have relapses than patients with low SPF, but the differences were not significant. Similarly, changes in FCM-DNA parameters were observed more often in patients who had relapses, but, again, the difference was not significant. In 5 of the 13 patients who had relapses, FCM-DNA analyses were performed on cytopunctures of the recurrences: patterns were identical to those observed before treatment even when the primary tumor regressed or showed changes in FCM-DNA parameters during chemotherapy. 相似文献
