VP45.25: Management of COVID‐19 associated with ultrasound use in obstetrics and gynecology/maternal‐fetal medicine

Abstract

As a cornerstone of obstetrics and gynecological care, ultrasound equipment needs to be properly cleaned and disinfected for safe patient use. We sought to determine the impacts of SARS-CoV2 on ultrasound infection prevention practices in maternal and fetal care. The objectives were to review the reported risks of SARS-CoV2 infection for pregnant women and in addition to the ISUOG guidelines, identify and analyse ultrasound infection prevention recommendations from global professional societies. A systematic review of studies assessing pregnancy outcomes in SARS-CoV2 infected patients was conducted. Global ultrasound infection prevention guidelines from professional societies involved with maternal and fetal care were identified and analysed for notable COVID-19 risks and infection prevention recommendations. The literature reported negative outcomes for COVID-19 during pregnancy demonstrating that pregnant women may be a high risk population during the pandemic. Disinfection of all medical equipment as well as their surrounding environment is an important consideration in minimising transmission-based precautions as recommended by guidelines identified. The same ultrasound guidelines also provide guidance around medical equipment use and reprocessing including ultrasound. The application of the Spaulding classification to determine appropriate disinfection level based on risk associated with intended use remains the recommended approach. There is a need for stringent infection prevention measures in settings providing care for pregnant patients. As the full impacts of COVID-19 on pregnancy emerge, these settings should review and upscale their infection prevention practices to protect maternal and fetal health and the health of healthcare workers. Disinfection of the ultrasound environment and equipment is an important part of infection prevention and facilities should consider stringent reprocessing policies as part of the fight against SARS-CoV2.
