Objectives: To assess the sufficiency of a structured course for the use of lung ultrasound in pregnant women and provide the interrater agreement of attendees with different expertise. Methods: 10 obstetricians with different expertise working in the COVID-19 setting participated to a single day, structured course given by a radiologist and an obstetrics & gynecology consultant experienced in performing LUS on pregnant women. Following a theoretical presentation, attendees underwent a hands-on course on 10 healthy and 5 pregnant women infected with COVID-19. Success was assessed with using pre-defined criteria. Instructors scored attendees consensually with a dichotomous (pass/fail) result for the following headings: pleural integrity, lung sliding sign, consolidations, A-& B-lines, light beam, white lung and artefacts. Secondly, attendees were asked to score a total of 12 still images and 12 videoclips consisting of 3 images/videoclips for each possible score (0-3). The Krippendorff's alpha test was used to assess the interrater agreement. Results: Out of 10 obstetricians, 8 obstetricians were found successful for all 8 characteristic features defined as minimum criteria (100%); 2 obstetricians were found successful in 7 of 8 criteria (87.5%). The interrater agreement of attendees were found as moderate to good (α = 0.757, 95%CI = 0.700-0.810) for rating still images (figure 1) and good to excellent (α = 0.882, 95%CI = 0.852-0.910) for videoclips. Conclusions: An adequate level of expertise in the use of lung ultrasound can be achieved with a short training course. After the training, observers showed good interrater agreement for interpreting lung ultrasound clips of healthy women and women with COVID-19.

Zhao 1 Objectives: The impact of COVID-19 and its complications in pregnant women and neonates, and the potential of vertical transmission remain unclear due to limited reports. Our study on COVID-19 positive pregnant women and their newborns provide insights on the imaging features, clinical characteristics and safety precautions during this pandemic. Methods: Retrospective analysis was performed on 19 women who delivered in our hospital from January 29 to March 31 2020 and were confirmed to have COVID-19 infection. Results: During the study period, a total of 4,210 pregnant women gave birth in our hospital, among which 19 were COVID-19 positive by nucleic acid, accounting for about 0.024%. There were only three symptomatic cases and the prenatal ultrasound didn't show any abnormalities for all 19 women. 18 women presented with pulmonary lesions and one case showed no abnormality on chest CT. Of the 20 neonates born to these mothers, 10 were admitted to the neonatal unit on the day of birth, and cardiac and cerebral ultrasound showed normal results. Each of the 10 newborns was tested twice for COVID-19 nucleic acid, and the results were all negative. Conclusions: In this group of pregnant women infected with COVID-19, most had no symptoms before delivery and developed symptoms during or after delivery. No evidence of COVID-19 infection was found in the newborns. Ultrasound showed no characteristic manifestations in fetuses and neonates. Chest CT was of diagnostic value in pregnant women infected with COVID-19. In light of the above characteristics, it is very important for the ultrasound department to take preventive and control measures for healthy pregnant women and the medical staff themselves.

The purpose the study is to perform a review of the literature on the international experience of the COVID-19 pandemic and pregnancy in northen hemisphere outbreak in preparing of the arrival in South America. Methods: A search of the PubMed database (Public MEDLINE), expanded for the keywords pregnancy / pregnant / novel coronavirus / SARS-COVID-2 / COVID-19, is performed from November 2019 to May 21, 2020. Results: A total of 365 articles were initially selected according to the search strategy designed. The total of articles selected according to the criteria were 42. A total of 1098 pregnant women and COVID-19 disease were analysed. The reported complications occur
