[摘要] 目的 分析不同注射剂 经粘膜下注射后液体水垫隆起高度下降速度。 方法 2015年6月—2016年6月于齐齐哈尔医学院附属第三医院对100个新鲜离体猪胃进行研究,以胃体部黏膜作为注射剂的注射点,分别抽取生理盐水、甘油果糖、20%甘露醇、15%葡萄糖及20%甘油后按照选取的5个位点依次进行注射。注射后,每5 min观察拍照测量,直至45 min。对隆起高度下降幅度使用方差分析进行统计。 结果 20%甘露醇组与生理盐水组在0~35 min总体均数差异有统计学意义(P<0.05),即在注射后前40 min甘露醇比生理盐水所形成的SFC高度下降幅度低。甘油果糖注射液组与生理盐水组在0~20 min总体均数差异有统计学意义(P<0.05),即在注射后前25 min甘油果糖比生理盐水所形成的SFC高度下降幅度低。15%葡萄糖、20%甘油、甘油果糖注射液、20%甘露醇所形成的SFC高度下降幅度之间的差异无统计学意义(P>0.05)。结论 前40 min甘露醇比生理盐水维持隆起效果好;前25 min甘油果糖比生理盐水维持隆起效果好;15%葡萄糖、甘油、甘油果糖、20%甘露醇维持隆起效果无明显差异。

[Abstract] Objective To analyze the liquid water cushion apophysis height decline speed of different injects after submucosal injection. Methods 100 fresh isolated pig stomachs in our hospital from June 2015 to June 2016 were researched, and the gastric fundic mucosa was used as the injection points, the normal saline, glycerin fructose, 20% mannitol, 15% glucose and 20% glycerol were respectively extracted for injection, after injection, the photograph measurement was observed per 5 min until 45 min, and the decline range of apophysis height was counted by the variance analysis. Results The difference in the population mean within 0~35 min between the 20% mannitol group and the normal saline group had statistical significance(P<0.05), the SFC height decline range formed by mannitol at 40 min after injection was lower than that formed by normal saline, and the difference in the population mean within 0~20 min between the glycerin fructose injection group and the normal saline group had statistical significance(P<0.05), the SFC height decline range formed by the glycerin fructose was lower than that formed by the normal saline, and the difference in the SFC height decline range formed by 15% glucose, 20% glycerine, glycerin fructose injection and 20% mannitol had no statistical significance(P>0.05). Conclusion The effect of maintaining apophysis of mannitol at 40 min after injection is better than that of normal saline, and the effect of maintaining apophysis of glycerin fructose is better than that of normal saline at 25 min after injection, and there was no obvious difference in the effect of maintaining apophysis between 15% glucose, glycerin, glycerin fructose and 20% mannitol.

胃癌在全部恶性肿瘤的死亡率中居于第2位。随着内镜技术的不断发展,给胃癌的早期诊治提供了一定的便利。EMR及ESD是消化内镜近些年发展起来的一种新的早期癌的治疗手段,这两种微创治疗技术能够对消化道早癌及癌前病变起到一定的治疗效果,将疾病早期发现并早期治疗,避免了癌症的进展[1-2]。应用两种技术应用治疗时需要将液体注射剂注射于病变組织黏膜下形成水垫,而减低治疗时出现穿孔这种并发症的可能性。不同注射剂形成的水垫起到的效果不同,选择一种较为适合的水垫对于EMR及ESD非常重要。2015年6月—2016年6月于齐齐哈尔医学院附属第三医院对100例离体猪胃进行研究,针对生理盐水、15%葡萄糖、甘油、甘露醇及甘油果糖等不同种类的注射剂,观察注射不同注射液后SFC的变化,从而选择出最为合适的黏膜注射药物。……
