Résumé
Background: Previous data of COVID-19 indicates the obstetric population to be at specified risk for critical COVID-19 disease. In this study patient records were analyzed to gain information about the connection between pregnancy and intensive care treatment due to COVID-19 infection. Material(s) and Method(s): A retrospective study of all COVID-19 positive obstetric patients in Helsinki University Hospital admitted to intensive care units (ICU) from the beginning of March 2020 until the end of January 2022. Primary outcome is to compare the number of COVID-19 positive obstetric ICU patients to all ICU patients. Secondary outcomes are maternal 30-day survival and immediate neonatal survival. The study also looks at number of variables related to pregnancy and ICU treatment including age, previous medical history, BMI and COVID-19 vaccination status, obstetric data (i.e., gestational weeks, obstetric complications and route of delivery), treatments received at the ICU and length of ICU and hospital stay. Result(s): In total 20 obstetric patients with COVID-19 were admitted to the intensive care unit during the observation period. This is 2,3% of all COVID-19 patients and 27,4% of all 18-45 years old female COVID-19 patients treated in the intensive care unit in Helsinki University Hospital. Maternal 30-day survival was 95% (n = 19). Immediate neonatal survival was 95% (n = 19). Conclusion(s): Pregnancy increased the risk of ICU admission for COVID-19 infection. These results align with previous studies reporting pregnancy as a risk for critical COVID-19 infection and ICU admission. The 30-day survival was high compared to all ICU patients.
