Abstract

Introduction: The early diagnosis of hemorrhage via postpartum ultrasound is crucial to initiate therapy and, thus, prevent maternal death. In these critical situations rapid availability and simple transport of ultrasound devices is vital, paving the way for a  new generation of portable handheld ultrasound devices (PUD) consisting of transducers and tablets or smart phones. However, evidence to confirm the diagnostic accuracy of these new devices is still scarce.

Methods: The accuracy and reliability of these new devices in relation to established standard ultrasound devices is analyses in this pilot study by comparing diagnoses and by applying statistical analysis via Bland-Altman plots, intraclass correlation coefficients (ICC), and Pearson correlation coefficients (PCC). One hundred patients of a university hospital were included in this study.

Results: In all cases, the same diagnosis was made regardless of the applied ultrasound device, confirming high accuracy. There was a high correlation (PCC 0.951) and excellent agreement (ICC 0.974) in the assessment of the cavum, while the assessment of the diameters of the uterus showed only a good correlation and a good agreement. Subgroup analysis for maternal weight, mode of delivery and day after delivery was performed  CONCLUSION: The same diagnosis independent of the used devices and excellent results of the cavum assessment promote the use of PUDs in a clinical setting. The slightly lower accuracy in the measurement of the uterus may be caused by the PUD's small acoustic window, reflecting one of its weaknesses. Therefore, the patient may benefit from the short time to diagnosis and the unbound location of examination, either in the delivery room, on the ward, or at home.

评估非压电便携式超声设备在产后护理中的准确性和可靠性。
导言:通过产后超声波对大出血进行早期诊断对于启动治疗,从而防止产妇死亡至关重要。在这些危急情况下,超声波设备的快速可用性和简便运输至关重要,这为由传感器和平板电脑或智能手机组成的新一代便携式手持超声波设备(PUD)铺平了道路。然而,证实这些新设备诊断准确性的证据仍然很少:本试验研究通过比较诊断结果,并通过布兰德-阿尔特曼图、类内相关系数(ICC)和皮尔逊相关系数(PCC)进行统计分析,分析了这些新设备与现有标准超声设备的准确性和可靠性。一家大学医院的 100 名患者参与了这项研究:在所有病例中,无论使用哪种超声设备,诊断结果都是相同的,证明了诊断的高度准确性。宫腔评估的相关性高(PCC 0.951),一致性好(ICC 0.974),而子宫直径评估的相关性和一致性较好。对产妇体重、分娩方式和产后天数进行了分组分析 结论:与所使用的设备无关的相同诊断结果和出色的宫腔评估结果促进了 PUD 在临床中的应用。子宫测量的准确性稍低可能是由于 PUD 的声窗较小,这反映了其弱点之一。因此,诊断时间短、检查地点不受限制(可在产房、病房或家中进行)可能会使患者受益。
