目的:观察掌上型彩超诊断仪对晚孕期产科急症病人超声扫查的图像清晰度及诊断准确性,以探讨掌上型彩超诊断仪在产科急诊中的应用价值。方法:通过采用掌上型彩超诊断仪及普通彩超诊断仪对2013年7月至2014年6月诊治的87例晚孕期产科急症孕妇进行前瞻性对比研究,按病种分为5组,分别比较两种彩超诊断仪二维图像的清晰度、彩色血流图的充盈度及对产科急症的诊断符合率。结果:掌上型彩超的二维灰阶图像清晰度略低于台式机,但彩色血流图的清晰度及充盈度均明显低于台式彩超仪;掌上型彩超对常见的前置胎盘、宫颈机能不全、羊水过少、胎儿宫内窘迫、脐带绕颈等产前急症的符合率为90%。结论:掌上型彩超对常见产科急症的诊断准确性较高,且携带方便,是产前急症超声诊断有用工具之一,值得临床推广使用。
OBJECTIVE: To observe the image clarity and diagnostic accuracy of handheld ultrasound scanner for obstetric emergencies in the first trimester of pregnancy, and to explore the value of handheld ultrasonography in obstetrics and gynecology emergency. Methods: A total of 87 pregnant women with obstetric emergencies diagnosed and treated during the first trimester of pregnancy from July 2013 to June 2014 were prospectively compared with each other by using a handheld color Doppler ultrasound scanner and an ordinary color Doppler ultrasound scanner. The patients were divided into five groups according to their disease types. The color Doppler ultrasound diagnostic imaging two-dimensional image clarity, color flow diagram of the filling degree and obstetric emergency diagnosis of coincidence rate. Results: The resolution of two-dimensional gray-scale images of PDA was slightly lower than that of desktop computers, but the clarity and filling degree of color flow maps were significantly lower than those of desktop color-ultrasonography. On the other hand, Incomplete, oligohydramnios, fetal distress, umbilical cord around the neck and other prenatal emergency compliance rate of 90%. Conclusion: The diagnostic accuracy of PDA on common obstetric emergencies is high and it is easy to carry. It is one of the useful tools for prenatal diagnosis of acute ultrasound and is worthy of clinical application.
