目的探讨B超定位在脐静脉置管术中的应用。方法对我科新生儿重症监护病房2012年7月至2013年12月在脐静脉置管术中应用B超定位的情况进行回顾性分析。结果152例新生儿进行了脐静脉置管术,B超定位下置管117例(76.9%)导管尖端位置合适,均予摄X线片判断插管位置,其中84例(71.8%)导管尖端位于T8-T9,23例(19.7%)位于T7,8例(6.8%)位于T10,2例(2.7%)位于T11。结论 B超定位应用于脐静脉置管术具有无创、准确和便捷的特点,避免了新生儿多次暴露X线的机会,值得推广使用。
Objective To investigate the application of B-ultrasound in umbilical vein catheterization. Methods The retrospective analysis of B ultrasound localization in umbilical vein catheterization from July 2012 to December 2013 in our department neonatal intensive care unit was performed. Results A total of 152 newborn infants underwent catheterization in the umbilical vein, and 117 cases (76.9%) underwent catheterization under the B ultrasound. The position of the catheter tip was suitable, and the position of the cannula was judged by X - ray. 84 cases (71.8% At T8-T9, 23 (19.7%) were located at T7, 8 (6.8%) were located at T10, and 2 (2.7%) were located at T11. Conclusion The application of B-ultrasound in umbilical vein catheterization is noninvasive, accurate and convenient. It avoids the chance of neonatal X-ray exposure for many times and is worth popularizing.
