Resposta para: Epistaxe como complicação de tratamento com cânula nasal de alto fluxo em adultos

A rare complication of high flow nasal cannula therapy in COVID-19: Caudal septal cartilage necrosis

“…Abdominal distansion, aspiration and rarely barotrauma (eg, pneumothorax) are complications of HFNC [3][4]. In adults, as a complication of high-flow nasal cannula therapy, epistaxis has observed only in a small study sample [5 ].We also observed nasal necrosis complication in our patient by using HFNC for a long time in COVID-19.…”

“…High-flow nasal cannula can be administered for prolonged periods (eg, days) and patients can be switched to conventional low-flow nasal cannulae once the flow rate reaches ≤20 L/minute and FiO2 ≤50 percent. Velasco et al attributed epistaxis to the following causes the maximum flow rate in the study by Velga et al was 40L/min, while the high flow rate in use was 65L/min and did not differ between patients with or without epistaxis [5][6].We also used HFNC in our patient for 32 days. During this time, other invasive or non-invasive methods were not used.…”
