OBJECTIVE
The purpose of the study is to compare conventional linear and fingertip ultrasound transducers, for the evaluation of umbilical catheters, with radiography. Fingertip ultrasound transducers have the potential to simplify sonographic examination due to their small size and ability to fit on a finger.
STUDY DESIGN
A prospective, IRB approved comparative study was performed. Linear and fingertip sonographic images were obtained around the same time as a radiograph in neonates with umbilical catheters by two board certified pediatric radiologists and a radiology resident. The positions of catheters were then compared across all three modalities.
RESULT
A total of 41 catheters were evaluated, which included 14 arterial and 27 venous catheters. Two venous catheters were not identified by the linear transducer and one arterial catheter tip was not identified by the fingertip transducer.
CONCLUSION
A fingertip ultrasound probe can be used to evaluate umbilical catheter positioning for potentially faster sonographic examination and decrease the need for repeated radiation.
目的
本研究旨在比较传统线性和指尖超声探头在评估脐导管方面的作用，将其与射线照相进行比较。由于指尖超声探头体积小且能够贴合手指，因此具有简化超声检查的潜力。
研究设计
进行了一项前瞻性、IRB 批准的对照研究。两名经过董事会认证的儿科放射科医生和一名放射科住院医师在同一时间对新生儿进行了线性和指尖超声检查，并同时拍摄了射线照片。然后，将导管的位置在所有三种模式下进行了比较。
结果
共评估了 41 根导管，其中包括 14 根动脉导管和 27 根静脉导管。有两根静脉导管无法被线性探头识别，一根动脉导管尖端无法被指尖探头识别。
结论
指尖超声探头可用于评估脐导管定位，以便更快地进行超声检查，并减少对重复射线照射的需求。
