Veno-venous extra-corporeal membrane oxygenation in a COVID-19 patient with cold-agglutinin haemolytic anaemia: A case report.

OVERVIEW: The use of extra-corporeal membrane oxygenation (ECMO) therapy to treat severe COVID-19 patients with acute respiratory failure is increasing worldwide. We reported herein the use of veno-venous ECMO in a patient with cold agglutinin haemolytic anaemia (CAHA) who suffered from severe COVID-19 infection. DESCRIPTION: A 64-year-old man presented to the emergency department (ED) with incremental complaints of dyspnoea and cough since one week. His history consisted of CAHA, which responded well to corticosteroid treatment. Because of severe hypoxemia, urgent intubation and mechanical ventilation were necessary. Despite deep sedation, muscle paralysis and prone ventilation, P/F ratio remained low. Though his history of CAHA, he still was considered for VV-ECMO. As lab results pointed to recurrence of CAHA, corticosteroids and rituximab were started. The VV-ECMO run was short and rather uncomplicated. Although, despite treatment, CAHA persisted and caused important complications of intestinal ischemia, which needed multiple surgical interventions. Finally, the patient suffered from progressive liver failure, thought to be secondary to ischemic cholangitis. One month after admission, therapy was stopped and patient passed away. CONCLUSION: Our case report shows that CAHA is no contraindication for VV-ECMO, even when both titre and thermal amplitude are high. Although, the aetiology of CAHA and its response to therapy will determine the final outcome of those patients.

Percutaneous tracheostomy for long-term ventilated COVID-19-patients: rationale and first clinical-safe for all-experience.

INTRODUCTION: COVID-19 infection has resulted in thousands of critically ill patients admitted to ICUs and treated with mechanical ventilation. Percutaneous tracheostomy is a well-known technique utilised as a strategy to wean critically ill patients from mechanical ventilation. Worldwide differences exist in terms of methods, operators, and settings, and questions remain regarding timing and indications. If tracheostomy is to be performed in COVID-19 patients, a safe environment is needed for optimal care. MATERIAL AND METHODS: We present a guidewire dilating forceps tracheostomy procedure in COVID-19 patients that was optimised including apnoea-moments, protective clothing, checklists, and clear protocols. We performed a retrospective analysis of the outcome after tracheostomy in COVID-19 patients between March 2020 and May 2020. RESULTS: The follow-up of the first 16 patients, median age 62 years, revealed a median intubation time until tracheostomy of 18 days and median cannulation time of 20 days. The overall perioperative complication rate and complication rate while cannulated was 19%, mainly superficial bleeding. None of the healthcare providers involved in performing the procedure developed any symptoms of the disease. CONCLUSIONS: This COVID-19-centred strategy based on flexibility, preparation, and cooperation between healthcare providers with different backgrounds facilitated percutaneous tracheostomy in COVID-19 patients without an increase in the overall complication rate or evidence of risk to healthcare providers. Our findings provide initial evidence that tracheostomy can be performed safely as a standard of care for COVID-19 patients requiring prolonged mechanical ventilation as was standard practice in ICU patients prior to the COVID-19 pandemic to promote ventilator weaning and patient recovery.
