We have noted that colons of patients prepared for colonoscopy with Golytely, a nonabsorbable electrolyte lavage solution, frequently contain foam which may obscure small mucosal lesions. Therefore, a randomized, blinded controlled trial was performed to determine the prevalence of Golytely-induced foam and the effect of supplemental simethicone in decreasing the prevalence of foam. Foam was present in 32% of colons prepared with Golytely alone but in none of the colons prepared with Golytely supplemented with simethicone. In addition, only 5% of colons prepared with supplemental simethicone had residual stool noted at the time of colonoscopy, a significant improvement over the 39% prevalence of residual stool in colons prepared with Golytely alone. Addition of simethicone to Golytely lavage decreases the prevalence of colonic foam and residual stool. 相似文献

目的 探讨链霉蛋白酶+西甲硅油在无痛胃镜患者检查前不同时间口服及服用后体位不同对检查效果的影响。方法 选择杭州市第一人民医院门诊及住院接受无痛胃镜检查的患者740例,随机分成链霉蛋白酶+西甲硅油组(n = 300)、西甲硅油组(n = 240)和对照组(盐酸利多卡因胶浆组,n = 200)。观察并对比3组患者在无痛胃镜检查前5、10、15、20、25、30、45和60 min口服上述药物及服药后患者采取不同体位[坐位、立位(间断行走)和卧位(间断左右侧身)]的胃镜视野清晰度、丙泊酚使用剂量、胃镜操作时间、恶心呕吐发生率、癌前病变和早期胃癌检出率。结果 链霉蛋白酶+西甲硅油组的胃镜视野清晰度、丙泊酚使用剂量、内镜操作时间和癌前病变及早期胃癌检出率明显优于西甲硅油组和对照组(P < 0.01),而西甲硅油组又优于对照组(P < 0.01);3组患者的恶心呕吐发生率比较,差异无统计学意义(P > 0.05)。链霉蛋白酶+西甲硅油组在无痛胃镜检查前20和25 min口服链霉蛋白酶+西甲硅油后,胃镜视野清晰度更佳(P < 0.05),但这两者间比较,差异无统计学意义(P > 0.05)。链霉蛋白酶+西甲硅油组采取立位(间断行走)和卧位(间断左右侧身)的胃镜视野清晰度优于坐位,差异有统计学意义(χ21 = 14.56,P1 = 0.000;χ22 = 16.61,P2 = 0.000);采取立位(间断行走)和卧位(间断左右侧身)的胃镜视野清晰度比较,差异无统计学意义(χ23 = 0.12,P3 = 0.733)。结论 无痛胃镜检查前应用链霉蛋白酶+西甲硅油可有效提高胃镜视野清晰度、缩短内镜操作时间、减少丙泊酚使用剂量、提高癌前病变及早期胃癌检出率;胃镜前20和25 min服药及服药后采取立位(间断行走)及卧位(间断左右侧身)效果更佳。 相似文献

Concern has been raised regarding the use of simethicone, a de‐foaming agent, during endoscopic procedures. Following reports of simethicone residue in endoscope channels despite high level disinfection, an endoscope manufacturer recommended that it not be used due to concerns of biofilm formation and a possible increased risk of microorganism transmission. However, a detailed mucosal assessment is essential in performing high‐standard endoscopic procedures. This is impaired by bubbles within the gastrointestinal lumen. The Gastroenterological Society of Australia's Infection Control in Endoscopy Guidelines (ICEG) Committee conducted a literature search utilizing the MEDLINE database. Further references were sourced from published paper bibliographies. Following a review of the available evidence, and drawing on extensive clinical experience, the multidisciplinary ICEG committee considered the risks and benefits of simethicone use in formulating four recommendations. Published reports have documented residual liquid or crystalline simethicone in endoscope channels after high level disinfection. There are no data confirming that simethicone can be cleared from channels by brushing. Multiple series report benefits of simethicone use during gastroscopy and colonoscopy in improving mucosal assessment, adenoma detection rate, and reducing procedure time. There are no published reports of adverse events related specifically to the use of simethicone, delivered either orally or via any endoscope channel. An assessment of the risks and benefits supports the continued use of simethicone during endoscopic procedures. Strict adherence to instrument reprocessing protocols is essential. 相似文献

目的:观察西甲硅油在胶囊内镜检查前肠道准备中的清洁和祛泡效果。方法将行胶囊内镜检查的278例患者随机分成研究组和对照组,均使用聚乙二醇电解质散2袋口服进行肠道准备,研究组于检查前1 h服用西甲硅油乳剂30 mL。观察两组患者肠道准备清洁度、肠道气泡量、不良反应发生情况、胶囊内镜小肠通过时间、全小肠检查成功率等指标。结果研究组肠道气泡量明显少于对照组(P<0.01),肠道准备过程中的不良反应发生率明显低于对照组(P<0.01)。两组患者肠道准备清洁度、胶囊内镜检查中的不良反应发生率、胶囊内镜小肠通过时间及全小肠检查成功率比较差异无统计学意义(P>0.05)。结论西甲硅油能够有效地去除胶囊内镜检查前肠道准备过程中产生的气泡,提高胶囊内镜检查时肠道视野清晰度,且能减少患者肠道准备过程中不良反应的发生。 相似文献
