目的:分析超低及极低出生体重儿母亲孕期危险因素,观察其出生后并发症、治疗效果及预后。方法:回顾性分析2015年10月—2017年10月收治的超低出生体重儿(ELBWI)及极低出生体重儿(VLBWI)的临床资料。结果:超低出生体重儿和极低出生体重儿...目的:分析超低及极低出生体重儿母亲孕期危险因素,观察其出生后并发症、治疗效果及预后。方法:回顾性分析2015年10月—2017年10月收治的超低出生体重儿(ELBWI)及极低出生体重儿(VLBWI)的临床资料。结果:超低出生体重儿和极低出生体重儿共62例,其中胎龄<28周6例,28~31周30例,32~36周26例;出生体质量<1 000 g 5例,1 000~1 249 g 12例,1 250~1 499 g 45例。ELBWI/VLBWI母亲孕期危险因素前三位分别为:胎膜早破15例(24.2%),双胎或多胎14例(22.6%),妊娠期高血压综合征9例(14.5%)。ELBWI/VLBWI并发症前五位分别为:低蛋白血症(47例,75.8%)、新生儿高胆红素血症(46例,74.2%)、酸碱平衡紊乱31例(50.0%)、新生儿呼吸窘迫综合征(NRDS)(29例,46.8%)、贫血(27例,43.5%)。NRDS、贫血、呼吸暂停及喂养不耐受更多出现于<28周及28~31周的婴儿,新生儿窒息更多出现于出生体重<1000 g及1000~1 249 g的婴儿。62例患儿存活52例,死亡10例,死亡率为16.1%。ELBWI婴儿存活率为40.0%,VLBWI婴儿存活率为87.7%。引起死亡的主要原因为家属放弃治疗,其次为NRDS、重症感染和肺出血。结论:加强围产期保健、积极防治各种并发症可以提高ELBWI及VLBWI的存活率。展开更多
目的探讨粪菌移植(FMT)在两种肠镜下盲肠置管术的临床应用。方法将2016年1月—2017年6月在我院通过肠镜下盲肠置管术进行粪菌移植的200例患者,随机分为A组和B组,各100例。A组采用直接肠镜置管法完成置管,B组采用二次肠镜置管法完成置管...目的探讨粪菌移植(FMT)在两种肠镜下盲肠置管术的临床应用。方法将2016年1月—2017年6月在我院通过肠镜下盲肠置管术进行粪菌移植的200例患者,随机分为A组和B组,各100例。A组采用直接肠镜置管法完成置管,B组采用二次肠镜置管法完成置管,对两组操作的置管成功率、置管时间、平均疼痛评分、并发症等情况进行对比。结果与A组相比较,B组到达盲肠时间略长但无统计学意义(14.95min vs15.26min,P=0.68)、疼痛评分低(5.7 vs 4.8,P<0.05)、更低的并发症发生率(6%vs 23%,P<0.05)。结论在粪菌移植内镜下盲肠置管术患者中,采用通过采用二次肠镜置管法与直接肠镜法相比较完成置管手术时间无统计学差异,但置管成功率高、患者的痛苦小、风险低,值得临床推广。展开更多
