脉搏血氧饱和度监测在新生儿先天性心脏病筛选中的应用分析

目的 探讨脉搏血氧饱和度（Sp02）监测在筛选诊断新生儿先天性心脏病中的作用。方法选择2011年5月-2012年5月产科新生儿共3212例，血氧饱和仪检测新生儿脉搏血氧饱和度，手与足部的脉搏血氧饱和度同时小于98％或手与足部的血氧饱和度差异大干±3％初步诊断为先天性心脏病患儿，初筛阳性患儿经心脏超声进一步鉴别诊断。结果3212名新生儿中脉搏血氧饱和度监测共筛选到41例阳性患儿，进一步对这41例患儿进行心脏超声检查，发现37例确诊为先天性心脏病患儿，确诊百分比为90．2％；排除4例，假阳性百分比为9．8％。结论脉搏氧饱和度（SpO2）监测对早期筛选先天性心脏病患儿具有较高的灵敏度，是一项安全、非侵人性、可行且合理的检测技术，值得临床产科推广使用。

Application analysis of pulse oxyhemoglobin saturation monitoring in screening neonatal congenital heart disease

Objective To explore the role of pulse oxyhemoglobin saturation （SpO2） monitoring in the screening and diagnosis of neonatal congenital heart disease. Methods A total of 3 212 neonates of the obstetric department from May 2011 to May 2012 were selected and their pulse oxyhemoglobin saturation was detected using the pulse oximetry. Neonates with the hand and the foot pulse oxyhemoglobin saturation less than 98% at the same time or with the differnce between the hand and the foot pulse oxyhemoglobin saturation greater than ± 3% were diagnosed with congenital heart disease initially. Cardiac ultrasound was used for the further differential diagnosis of preliminary positive neonates. Results Of the 3212 neonates, a total of 41 positive neonates were screened out by the pulse oxyhemoglobin saturation monitoring, who received cardiac ultrasound test for further diagnosis. It was found that 37 neonates were confirmed with congenital heart disease, with the confirm rate of 90.2%, and 4 cases were excluded, with the false positive rate of 9.8%. Conclusion The pulse oxyhemoglobin saturation （SpO2） monitoring is a highly sensitive, safe, noninvasive, feasible and reasonable detection technique for the early screening of neonatal congenital heart disease, thereby worthy of promotion and application in the obstetric department.
