简介:摘要目的探讨妊娠合并梅毒感染对母婴的影响。方法抽取2016年8月~2017年8月在我院就诊的56例妊娠合并梅毒患者作为研究对象,按随机数字表法分为观察组与对照组,各28例;对照组不进行治疗,观察组行全疗程抗梅毒治疗,应用苄星青霉素240万单位肌内注射,每周1次连续3周,观察并比较两组患者的妊娠结局、新生儿预后效果。结果观察组足月分娩率、早产率及死产、死胎率与对照组相比较有显著性差异(P<0.05)。治疗组先天性梅毒患儿发生率与对照组比较有显著性差异(P<0.05)。结论妊娠合并梅毒患者有不良妊娠结局,在孕早期行规范的抗梅毒治疗,能减少流产、早产、死胎及先天梅毒儿的发生,同时采取早期诊断及治疗措施能够为梅毒患者的安全妊娠提供保证。

简介:摘要目的对消化内科患者的恶心呕吐原因进行临床分析,增强对内科疾病导致恶心呕吐的认识,为临床诊断提供依据,避免漏诊及误诊的发生。方法回顾性分析2016年8月至2017年3月我院消化内科以恶心呕吐为主要症状的56例住院患者的病例资料。结果56例患者疾病类型中,消化系统疾病所致呕吐所占比例为80.36%,是患者发生呕吐的主要原因,其中以慢性胃炎最为常见,占53.69%;非消化系统疾病占20%,以糖尿病胃轻瘫多见,占6.67%。对确诊患者进行针对性的治疗后,总有效率达80%。结论引起消化内科患者发生恶心呕吐的病因比较复杂,特征达80%不典型,临床医生应建立良好的诊断思路和治疗方法。
