BACKGROUND: COVID-19 is a global pandemic with many patients requiring prolonged mechanical ventilation. COVID-19 is associated with laryngeal oedema and a high rate of reintubation and difficult airway. Tracheostomy insertion is an aerosol generating procedure, so we strived to make our novel technique safe for operator and patient.
AIM: To share our experience of a novel percutaneous tracheostomy technique, based on a case series of 18 patients with COVID-19 pneumonitis.
METHOD: Our novel percutaneous tracheostomy technique is a landmark-based approach without bronchoscopic confirmation of the correct needle placement. Blunt dissection using tracheal dilators onto the tracheal rings facilitates first pass needle insertion into the trachea. The tracheal tube is retracted into the supraglottic airway, the cuff overinflated, and a wet throat pack inserted to reduce aerosolisation.
RESULTS: From March 2020 to May 2020, 38 patients with suspected or confirmed COVID-19 presented to Royal Bolton Hospital requiring invasive ventilation. 18 patients underwent percutaneous tracheostomy. 6 patients have been decannulated, 12 patients died. Mean time from intubation to tracheostomy was 6.1 days and from tracheostomy to decannulation 20.6 days. No operator developed COVID-19 symptoms.
CONCLUSIONS: Despite the low numbers our novel technique appears to be safe, but confirmation requires a larger controlled trial. As an institution we have avoided difficulties with reintubation and reduced our drug usage.
