ABSTRACT

Coronavirus disease 2019 (COVID-19) could emerge not only as viral pneumonia but also as a cardiovascular disease. Thromboprophylaxis has been recommended by the current guidelines, especially COVID-19 patients who are hospitalized. On the other hand, these drugs might cause serious bleeding complications. Hereby, we aimed to report three cases with spontaneous rectus sheath hematoma (RSH) developed after being administered thromboprophylaxis for severe COVID-19 pneumonia. In this case series, we draw attention to the rare, but mortal complication of the COVID-19 thromboprophylaxis regimen.

ABSTRACT

TYPE: Late Breaking TOPIC: Pulmonary Physiology PURPOSE: INTRODUCTION: The clinical and physiological effects of long-duration use of N95-type masks without ventilation valves, on healthcare workers during the Coronavirus Disease-2019 (COVID-19) pandemic were evaluated. METHODS: All volunteering personnel working in operating theater using non-ventilated N95 type respiratory masks, minimum for a 2-hour non-interrupted duration were observed. The partial oxygen saturation (SpO2) and heart rate (HR) were recorded before wearing the N95 mask, and at 1st and 2nd hour. Volunteers were then questioned for any symptoms. RESULTS: Total of 116 measurements were completed in 29 (13 male, 16 female) eligible volunteers, each having 4 measurements, on different days. Median age was 32.5. Pre-mask, 1st hour, and 2nd hour median values for SpO2 were 98%, 97% and 96%, respectively (p<0.001). Median HR was 75 pre-mask, 79 at 1st hour, and 84/min at 2nd hour (p<0.001). Significant difference between all-three consecutive measurements of HR was achieved. Statistical difference was only reached between pre-mask and other SpO2 measurements (1st and 2nd hour). Complaints seen in group were head ache (34%), shortness of breath (23%), palpitation (19%), and nausea feeling (3%). Two individuals took off their masks to breathe, on 87th and 105th minutes, respectively. CONCLUSIONS: Long duration (>1 hour) use of N95-type masks cause significant reduction in SpO2 measurements and increase in heart rate. CLINICAL IMPLICATIONS:.Despite being a crucial personal protective equipment in COVID-19 pandemic, especially for health workers in operating rooms, it should be used with caution in people with known heart and/or pulmonary insufficiency, and with short intermittent time periods. DISCLOSURE: No significant relationships. KEYWORD: COVID-19
