SESSION TITLE: Global Case Reports in Critical Care SESSION TYPE: Global Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 01:45 pm INTRODUCTION: Thrombotic complications in patients diagnosed with COVID-19 pneumonia are emerging as an important and significant morbidity and mortality burden, with overwhelming inflammation, hypoxia, immobilization, and diffuse intravascular coagulation among possible causes of a procoagulant state (1). Obstructive sleep apnea (OSA), with intermittent arterial oxygen desaturation, may in its turn contribute to a procoagulant state, causing hemodynamic alterations as polycythemia and sluggish blood flow (2). Here we report on a case of sudden and massive non-lethal pulmonary thromboembolism (PTE) in a patient with COVID-19 severe pneumonia, for whom OSA was suspected and documented as a possible concurrent mechanism of thromboembolic complication during follow-up. CASE PRESENTATION: A 55-year-old male non-smoker obese (BMI 33 Kg/m2) was admitted to our hospital after 9 days of fever. In the Emergency Room, a chest HRCT scan showed bilateral diffuse ground glass opacities. He was treated with subcutaneous Tocilizumab (324 mg) single shot, Remdesivir (200 mg/day for first day and 100/daily for further 4 days), methyl-prednisolone 40 mg/daily, Enoxaparin 6000 UI/twice daily, azithromycin 500 mg/daily, high flow nasal cannula oxygen (50 L/min, TC 34°C, FiO2 35%) for moderate acute respiratory failure due to COVID-19 pneumonia (pO2: 58 mmHg, PCO2 34 mmHg pH 7.50, P/F 275). After 10 days, patient's clinical conditions worsened, needing non-invasive respiratory support;D-dimer increased abruptly, rising to 10 ng/mL, with findings consistent with PTE at a computed tomographic angiography (CTA, Fig 1). The patient was successfully treated with 10 mg/daily subcutaneous fondaparinux for 12 days, while assisted in the Intensive Care Unit, being discharged home in room air shortly later with oral anticoagulants. At the 3-month follow-up visit, OSA was suspected due to reported excessive daytime sleepiness and weakness, snoring, disturbed night sleep, morning headache in the last 4 years. The patient underwent a home sleep apnea test (HSAT) overnight. Test results revealed an AHI of 50 events/h, with several prolonged episodes of obstructive sleep apnea (307 apnea and hypopnea (A+H) events, 70 obstructive apnea and 233 hypopnea events, with a mean duration of 10% and an average arterial saturation of 93% (Fig. 2). He was adapted to CPAP therapy, with benefit and good correction of polygraphic indexes. DISCUSSION: The pathogenetic mechanisms of COVID 19 and OSA could have played a synergistic effect on endothelial damage, thus increasing the risk of thromboembolism. CONCLUSIONS: The presence of underdiagnosed comorbidities may well worsen the clinical course and complication of COVID-19;an earlier diagnosis of OSA is a prerequisite for timely treatment and, potentially, improved long-term clinical outcomes.

ABSTRACT
BACKGROUND: The COVID-19 epidemic became a challenge for Emergency Departments (ED) and a remarkable reduction in surgical emergencies has been widely noticed. Aim of the present study was to evaluate the impact of the pandemic period in the need of surgical emergencies. METHODS: Between January 1st and May 31st 2020 all the consecutive general surgery emergencies performed by the Careggi University hospital emergency surgery unit were prospectively recorded and compared to the same period of 2019. Demographic and clinical data were recorded and analyzed. RESULTS: The number of surgical procedures decreased only in the month of March 2020 (compared to 2019), while in April the total numer of emergency surgical procedures was similar. Only appendectomy, complicated hernia repair and colonic resection were significantly reduced (40%, 48% and 33% respectively). The number of small intestine excision, cholecystectomy and lysis of peritoneal adhesions remained stable throughout the entire period. No statistically significant differences were found considering age, sex, Emergency Surgery Score, mortality, ICU postoperative admission and time between admission and surgery, even when analyzed with multivariate analysis for every single surgical procedure, suggesting a comparable disease severity and comorbility patterns. Mortality in COVID patients was 25%, compared to 7% of no-covid patients. CONCLUSIONS: The COVID pandemic has caused major changes in daily clinical practice, especially in areas such as Emergency. This has led to a temporary reduction and changes in the flow of patients to the emergency room, with implications also for emergency surgical activities.
