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.
期刊介绍:
Founded in 1870 as "Archiv für Gynaekologie", Archives of Gynecology and Obstetrics has a long and outstanding tradition. Since 1922 the journal has been the Organ of the Deutsche Gesellschaft für Gynäkologie und Geburtshilfe. "The Archives of Gynecology and Obstetrics" is circulated in over 40 countries world wide and is indexed in "PubMed/Medline" and "Science Citation Index Expanded/Journal Citation Report".
The journal publishes invited and submitted reviews; peer-reviewed original articles about clinical topics and basic research as well as news and views and guidelines and position statements from all sub-specialties in gynecology and obstetrics.
