自从2001年初双气囊小肠镜问世以来,此项技术已在世界范围内得到广泛的应用.目前有关双气囊小肠镜临床应用的研究日益增多,主要涉及双气囊小肠镜的临床应用、适应证、对小肠疾病的整体检出率、小肠镜下治疗、操作并发症等[1].2006年8月在日本东京召开的第一届双气囊小肠镜临床应用学术研讨会上,小肠镜的发明者日本的山本博德有鉴于此项技术使用范围的日益扩大,建议将双气囊小肠镜改名为推进式双气囊电子小肠镜. 相似文献

小肠位置特殊,疾病诊断困难,长约600~800cm,疾病诊断困难。传统的检查方法如小肠钡剂、x线检查等对小肠疾病诊断价值低。无痛性双气囊电子小肠镜具有可直视整个小肠的病变情况、图像清晰、操作可控、能取活检及镜下治疗等优点,比传统检查有明显的优越性,是目前小肠疾病检查的新方法”’,现就双气囊小肠镜检查前后护理总结如下:1.临床资料2013年9月至2014年6月,我科为27例患者实行了双气囊小肠镜检查,其中男性16例,女性11例,年龄16~78岁。因消化道症状(便血、腹痛、腹泻、不全性肠梗、不明原因消瘦等)而人住我科,经胃镜、结肠镜、钡餐等检查未发现明显器质性病变。 相似文献

目的分析气管插管麻醉在双气囊电子小肠镜检查中的临床应用价值。方法收集我院2011年6月—2013年6月期间接收的需要实施双气囊电子小肠镜检查的小肠疾病患者85例作为研究对象,所有患者均应用气管插管麻醉,回顾性分析患者的临床资料,总结其临床应用价值。结果研究结果显示,本组患者在检查过程中,心率、血压、血氧饱和度等生命体征均未出现明显的变化,所有患者均安全完成小肠镜检查。在本次检查过程中,有1例患者由于回盲部狭窄及变形导致小肠镜无法通过狭窄部,有1例患者由于十二指肠水平部狭窄而终止进镜,有3例患者由于回肠末端狭窄中止进镜,另外80名患者经口检查均到达回肠上段或中段,本组患者检查时间60-87min,平均(73.8±10.28)min,无一例严重并发症出现。结论气管插管麻醉应用于双气囊电子小肠镜检查能效提高检查过程的安全性,保障小肠镜检查的顺利实施,具有非常重要的临床应用价值,值得在临床应用上推广。 相似文献

目的: 双气囊推进式小肠镜的发展使医生能够直接观察小肠,本研究的目的在于探讨该设备在结肠镜和胃镜检查均阴性的55例患者中的诊断和治疗意义.方法: 采用双气囊推进式小肠镜EN-450P,在检查过程中,大部分患者采用清醒镇静,注意观察记录患者的并发症、检查时间、进镜途径及检查阳性率.患者的症状和体征、诊断和预后都有详细记载.结果: 本组患者的检查结果的阳性率为94.5%(52/55),其中不明原因的小肠出血占43.6%(24/55),是该项检查的主要适应症,平均检查时间是45分钟.3例患者因为没有获得全肠道的检查而未确诊,从而从相反地方向重新检查.5例患者获得全胃肠检查.在镇静剂的帮助下,患者可以很好的耐受检查.3例患者因为腹腔严重粘连导致进镜困难而放弃检查.所有的患者均有随访.大多数器质性疾病(除了病变部位有活动性出血)的患者均有病理诊断.一位胃大部切除患者发生肠扭转造成肠梗阻,在完成检查后,完全恢复.结论: 双气囊推进式小肠镜能够肉眼观察全小肠,并能够得到病理诊断,并能够大体对病变进行定位.在镇静剂的帮助下,患者能够很好的耐受检查.它的适应症为:不明原因的消化道出血、慢性腹泻、慢性腹痛和不完全肠梗阻.它不仅是一项检查手段,在某种意义上来说,它还可以是一种治疗手段.检查失败的主要原因是腹腔粘连. 相似文献

Determinations of benzene concentration in blood and of phenol in urine were made by head-space gas chromatography techniques on samples taken near the end of the work day from two groups of workers potentially exposed to low levels of benzene in the work-place atmosphere. Preliminary results suggest that benzene in blood is more reliable than phenol tests for assessing both exposure and uptake of benzene. Normal values of phenol in urine (10 mg/liter or less) were found in nearly all those cases in which benzene was detected in the blood. 相似文献

Objective: The objective of this study is to examine if overall correlation exists among cadmium levels (Cd) in the general environment,
dietary Cd intake, and Cd body burden of local residents. Methods: Eleven prefectures in Japan were selected as the areas where large-scale data on Cd levels in urine of adult women (40–49
and 50–59 years of age, respectively) were available to calculate geometric mean (GM) values for each of the prefecture. Other
data were cited from published or previously established databases on Cd in the sediments of river bottoms (as a representative
of Cd in the environment), Cd in rice for local consumption, and Cd in daily food duplicate samples collected from local women
populations, and calculated for GM values for the prefectures. The GM values were subjected to correlation matrix and regression
analysis. Results: Marginally significant (P<0.10) correlation was detected between Cd in sediment and Cd in rice. Furthermore, correlation of Cd in sediment was significant
with Cd in total foods (P<0.05) and possibly with Cd in urine (P<0.05–0.10). Importance of data on Cd in rice paddy soil as a missing link is discussed. Conclusions: Correlation was demonstrated in the flow of Cd transport from the environment (expressed as Cd contents in river sediments)
to humans (in terms of Cd in urine) among general populations in Japan. 相似文献

BACKGROUND: Ragpickers are informal workers who collect recyclable materials to earn a small wage. Their life and working conditions are extremely precarious. The ergonomic hazards and musculoskeletal pain in a sample of ragpickers in Pelotas, a city in southern Brazil are examined. METHODS: Two comparison groups were available: a matched sample of non-ragpickers from the same poor neighborhoods, and a random sample of the general population of the city. The cross-sectional study gathered data by interview on 990 individuals in 2004. Musculoskeletal pain was assessed using the Standardized Nordic Questionnaire. RESULTS: Ragpickers reported higher prevalences for most awkward postures and ergonomic exposures compared to neighbors with other demanding manual jobs. The prevalence within the last 12 months of low back pain (LBP), lower extremity pain (LEP), and upper extremity pain (UEP) among ragpickers were 49.2%, 45.1%, and 34.9%, respectively; levels similar to those reported by neighborhood controls. Both ragpickers and non-ragpickers reported considerably higher ergonomic exposures, and more prevalent LBP, than the general population. CONCLUSIONS: Ragpickers experience many occupational hazards and ergonomic stressors. Their overall prevalence of musculoskeletal pain was similar to a comparison group with other physically demanding manual jobs. For LBP, this prevalence was substantially higher (49% vs. 35%) than in the general population. 相似文献

STUDY OBJECTIVE: To determine the extent of the inequalities in self reported health between socioeconomic groups and its changes over time in the Basque Country (Spain). DESIGN: Cross sectional data on the association between occupation, education and income and three health indicators was obtained from the Basque Health Surveys of 1986 and 1992. Representative population samples were analysed. In 1986 the number of respondents was 24 657 and in 1992, 13 277. SETTING: Basque Country, Spain. MAIN OUTCOME MEASURES: The effect of socioeconomic position on health and the magnitude of social inequalities in health were quantified using the odds ratios based on logistic regression analysis, and the Relative Index of Inequality. RESULTS: As was expected, social inequalities in self reported health existed in both surveys, but the social gradient was greater in 1992. Social differences varied according to gender and health indicator. According to education an increase in social inequalities was observed consistently in all the health indicators except long term conditions in women. A consistent increase in inequalities in limiting longstanding illness was also observed according to all socioeconomic indicators. CONCLUSIONS: These results agree to a large extent with those of previous studies in other countries. In this context the unequal distribution of material circumstances and working conditions between socioeconomic groups seem to play a major part in health inequalities. The worsening of the labour market during this period and the onset of a new economic recession may explain the increase in social inequalities over time. 相似文献
