新生儿医用粘胶相关皮肤损伤危险因素分析及其护理对策

目的探讨新生儿医用粘胶相关性皮肤损伤(MARSI)危险因素和护理对策。方法选取2016年4月至2018年5月在本院接受治疗的新生儿483例为研究对象,统计其发生MARSI例数和损伤类型,依据是否发生MARSI将患儿分成MARSI组61例和未发生MARSI组422例,记录患儿温箱、胎龄、抢救台、出生体质量、潮湿多汗、蓝光治疗、感染、留置胃管、禁食、经外周静脉置入中心静脉导管(PICC)、水肿及皮肤干燥情况,对影响患儿发生MARSI的因素进行多因素logistic回归分析。结果患儿皮肤受损类型依次为表皮剥脱伤(6.21%)、皮肤撕裂伤(3.73%)、接触性皮炎1.45%。蓝光治疗、留置胃管、出生体质量<2200 g、胎龄<30周及皮肤干燥为患儿发生MARSI的独立危险因素(P<0.05)。结论临床新生儿MARSI发生率较高,且影响因素多,医护人员应采用有针对性护理措施,加强防范,以降低新生儿MARSI的发生率。     

一次性湿热交换器在新生儿机械通气长途转运中应用的效果分析

目的探讨研究一次性湿热交换器在新生儿机械通气长途转运中应用的临床意义。方法 2017年1月-2017年12月,我院120转运中心长途转运接收786例机械通气新生儿,786例患儿随机分为常规气道护理(对照组)和转运途中应用一次性湿热交换器组(治疗组),对比转运过程中的吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率。结果研究数据显示治疗组吸痰次数、肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率有显著性差异(P<0.05)明显低于对照组。结论在机械通气新生儿长途转运中,一次性湿热交换器的可减少转运患儿吸痰次数发生率、降低肉眼可见痰痂形成率、堵管发生率、脱管发生率、人机对抗发生率具有明显优越性,值得推广。     

近红外光谱仪监测窒息新生儿听觉刺激诱发时的脑氧合代谢及脑血流变化

目的了解窒息新生儿在听觉刺激诱发脑神经活动时的脑氧合代谢和脑血流量的改变。 方法1998~2003年北京中日友好医院儿科选择窒息新生儿34例为窒息组，健康新生儿40名为对照组。使用近红外光谱仪，观察听觉刺激试验诱发的脑氧合血红蛋白\[Hb O2\]、还原血红蛋白\[Hb H\]和总血红蛋白\[Hb tot\]浓度的变化，并比较两组脑氧合代谢和脑血流量的改变。根据\[Hb O2\]、\[Hb H\]和\[Hb tot\]不同的变化，将氧合代谢曲线分为A(\[Hb O2\]、\[Hb H\]和\[Hb tot\]均增加)； B(\[Hb O2\]和\[Hb tot\]增加,\[Hb H\]降低)；C(\[Hb O2\]和\[Hb tot\]降低,\[Hb H\]增加)3种曲线类型。 结果窒息组中25例(25/34、73.5%)显示C型变化，对照组中28例(28/40、70.0%)显示A型变化，两组中A、C两型例数比较差异显著(P<0.05)。两组\[Hb O2\]和\[Hb tot\]数值变化幅度比较差异显著(P<0.05)。 结论窒息新生儿听觉刺激诱发相应皮层的神经活动时，显示局部脑血流量下降、氧合代谢降低，重度窒息儿更明显。     

Neonatal osteofibrous dysplasia: a case report

We describe a case of neonatal osteofibrous dysplasia that was diagnosed 3 days after birth. Osteofibrous dysplasia is a fibro-osseous lesion rarely seen in long bones. It is also known as congenital osteitis fibrosa or ossifying fibroma of bones. Although it occurs in children under 10 years of age, it is extremely rare in newborn babies. It must be differentiated from adamantinoma due to their radiological appearance, predilection for tibia and fibula, clinical picture, and certain histological similarities.     

双胎输血综合征29对临床分析

目的：探讨新生儿双胎输血综合征的临床表现及其合并症等问题。方法：对过去10年间收治的29对双胎输血综合征患儿资料进行回顾性分析。结果：双胎输血综合征患儿有一般双胎儿的临床共性，且双胎输血综合征患儿中受血儿出现病理临床表现及合并症较供血儿多且严重。结论：双胎输血综合征对受血儿危害更大，故临床上一旦确诊为双胎输血综合征，应对受血儿进行严密监护，若出现临床表现，并发生红细胞增多症，应积极采取治疗措施，以减少严重并发症及后遗症的发生。     

新法复苏对新生儿的近期影响(附5223例新旧法复苏对比分析)

对比分析开展新法ABCDE复苏前12个月、后12个月共计5223例有关临床因素，发现开展新法复苏后12个月比前12个月新生儿窒息发生数由5.04％（142／2818）下降到4.75％（110／2405）。早期新生儿患病数由20．47％（577／2818）下降到15．17％（365／2405），因产儿亡率由17．7％。（50／2818）下降到9．5‰（23／2405），且后二者相比P值分别小于0.01及0.05，显示严格按照ABCDE方案实施新生儿娩出的复苏对新生儿有良好的近期影响。本文还讨论了新旧复苏方法的主要不同点及新法复苏对新生儿这些良好近期影响的关键是保持呼吸造通畅，建立呼吸及维持循环首三步、阻止或缩短新生地缺氧。     

Respiratory muscle rigidity in a preterm infant after use of fentanyl during Caesarean section

Fentanyl is in many neonatal intensive care units the sedative of choice. One side-effect is, however, the possibility of muscle and/or chest wall rigidity. A pregnant woman with a critical pulmonary valve stenosis had a balloon dilatation at 26 weeks of gestation. She was put on propranolol, but went into a severe cardiac failure. In week 31, she developed pregnancy induced hypertension. Periodically absent diastolic flow in the umbilical cord was demonstrated. A Caesarean section was performed using fentanyl as analgesia. A boy weighing 1440 g, had a 1 min Apgar score of 3 without respiratory movements. Mask ventilation was tried, but chest wall expansion was not achieved despite using high pressures. He was intubated and positive pressure ventilation attempted, with the same result. Despite the use of high pressures up to 60–70 cm H₂O, no chest movement could be achieved. An intravenous line was established in order to give naloxone and pancuronium. Just before the drugs were given, chest wall movements were achieved and the heart rate normalized. Conclusion This is the first report on chest wall rigidity in a neonate after administration of fentanyl to the mother during Caesarean section. Received: 15 August 1997 and in revised form 30 January 1998 / Accepted 3 February 1998
