鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗新生儿急性呼吸窘迫综合征疾病的临床应用研究

目的:分析鼻塞式同步间歇正压通气(NIPPV)联合布地奈德雾化治疗ARDS(新生儿急性呼吸窘迫综合征)疾病的临床应用效果。方法:纳入病例是2017年5月—2019年11月收治的104例ARDS新生儿,随机平均分为两组。参照组52例采纳CPAP(持续气道正压通气通气)治疗,实验组52例采纳NIPPV+布地奈德雾化治疗,对比两组呼吸机通气时间、用氧时间、住院时间、血气指标以及并发症发生情况。结果:实验组呼吸机通气时间、用氧时间、住院时间均明显短于参照组,差异有统计学意义P<0.05;实验组治疗3 d后PaCO2明显低于参照组,实验组治疗3 d后PH以及PaO2明显高于参照组,差异有统计学意义P<0.05;实验组并发症发生率(3.85%,2/52)明显低于参照组(21.15%,11/52),差异有统计学意义P<0.05。结论:NIPPV+布地奈德雾化可有效缩短ARDS患者机械通气时间,改善血气指标,降低并发症发生率,值得借鉴。     

Neonatal necrotizing enterocolitis

PURPOSE: A retrospective, 12-year review of neonatal necrotizing enterocolitis was undertaken at a county hospital, with emphasis on presentation signs and symptoms. METHODS: Eighty-two patients with presence of intramural air were included in the study. The following signs and symptoms were studied: evidence of respiratory distress, use of umbilical catheters, white blood cell count and temperature at presentation, time interval from birth to diagnosis and time interval from diagnosis to operative intervention, presence of intramural air, air in biliary tree or free air, changes in abdominal girth, and presence of occult or gross blood in stools. Comparison was done among infants who had surgical or medical treatment, premature and full-term infants, and infants who had neonatal necrotizing enterocolitis less than or more than 20 days after birth. RESULTS: Eleven patients had a fatal outcome, with an overall survival of 87 percent. Sixty-four patients were treated medically and 18 had operative treatment. Mortality of the surgically treated group was 44 percent. Neonates who had surgical intervention had a left shift of the white blood cell count more commonly present, and all had documented abdominal distention. There were 62 premature and 20 full-term neonates in the group. Full-term neonates developed neonatal necrotizing enterocolitis earlier after birth (5.3 days compared with 15.3 days in the premature neonate group). Full-term neonates had a better prognosis in our series. Presentation of symptoms more than 20 days after birth did not change outcome. CONCLUSION: Our results reflect the experience of a community-based hospital. Clinical acumen remains the cornerstone of diagnosis and management.     

新生儿呕吐性疾病的消化道造影研究

目的:研究新生儿呕吐性疾病的造影技术,探讨其影像特征。方法:对比剂引入方式采用吸吮法和插胃管抽液后再注入对比剂两种方法;选用对比剂有6 0 %～80 % (W/V)的硫酸钡混悬液30～4 0ml或30 %泛影葡胺30ml;采用不同体位多轴位观察摄片,并对5 4例造影表现进行分析。结果:5 4例新生儿消化道造影均满足诊断要求,其中先天性幽门狭窄11例(19 6 % ) ,胃食管反流34例(6 3 0 % ) ,环形胰腺9例(16 .7% )。经手术治疗2 0例均与术前X线诊断相一致。结论:传统的上消化道造影是诊断新生儿呕吐病因的有效方法,熟练掌握造影技术和特有的造影征像能够及时地明确诊断。     

新生儿窒息124例临床分析

目的探讨预防新生儿窒息的措施，以降低新生儿窒息的发生率。方法收集我院124例新生儿窒息的临床资料，分析发病的相关高危因素。结果窒息的相关因素依次为：早产因素34例居首位，占27．4％；羊水过少占14．5％；胎位异常占10．5％；产程异常占9．7％；脐带因素（缠绕、脱垂及过短）占8．9％；巨大儿占8．9％；胎盘早剥及前置胎盘占6．5％；妊娠高血压综合征占5．6％；宫内生长迟缓（IUGR）占3．2％。结论加大孕产妇分级管理的力度，加强孕期保健和产前检查，适时纠正臀位，尽量减少早产，及早发现和正确处理胎儿宫内窘迫，是降低新生儿重度窒息的有效措施。     

静脉用丙种球蛋白治疗新生儿重症感染对细胞免疫功能的影响

应用静脉注丙球(IVIG),配合抗生素(An)治疗重症感染新生儿12例,在观察疗效及不良反应的同时,通过检测患儿治疗前后T细胞亚群及白细胞介素Ⅱ(IL-2)产生水平的变化,观察IVIG对细胞免疫功能的影响。结果显示:患儿CD_3~+、CD_4~+、CD_8~+细胞及IL-2产生水平均明显低于正常同龄新生儿。经IVIG+An及单用An治疗后,T细胞各亚群及IL-2水平均明显增高。IVIG组与An组比较,诒疗后IVIG组CD_4~+细胞明显高于An组,IL-2水平也较An组为高,但无统计学意义。疗效观察,中毒症状及原发病体征好转消失时间IVIG组较An组明显缩短。本文还就IVIG对细胞免疫功能影响的可能机制进行了讨论。     

Ventriculosubcutaneous shunt for temporary treatment of neonatal post-IVH hydrocephalus: a technical note

A technique for temporary ventricular drainage using a subcutaneous pouch is described for use in neonatal hydrocephalus after intraventricular hemorrhage. The advantages include continuous, valve-regulated ventricular decompression, no exposed tubing, avoidance of electrolyte imbalance and of the loss of CSF, obviation of the need for repeated tapping, and the ability to convert to a peritoneal shunt on an elective basis.
