Meeting established criteria for tracheostomy decannulation should improve success, although there will be a small proportion of patients with a tracheostomy who fail decannulation. Failure rates depend on patient characteristics and disparity between institutional practices and expert opinion. However, there are no widely accepted published failure rates, or agreement on the time-point at which failure is assessed. We present a patient who had evidence of readiness for decannulation, but had immediate failure due to extrinsic tracheal compression, which proved difficult to diagnose and required surgery to resolve. Capping the tracheostomy before decannulation may or may not have given rise to suspicion of potential failure and this practice requires further evaluation as it is not without risk. For subglottic, but suprastomal lesions, nasendoscopy is not of value. It is important to decannulate patients in a safe environment, preferably early in the day to allow post decannulation observations and interventions should they become necessary, and with the close involvement of the multi-professional team. This report illustrates the failure of our standard Tracheostomy decannulation criteria, and direct upper airway view to identify suprastomal tracheal pathology, and we discuss the potential for additional criteria which may have identified the issue before decannulation attempts.

COVIDTrach is a UK multidisciplinary collaborative project that aims to evaluate the outcomes of tracheostomy in COVID-19 patients. It also examines the implementation of national guidance in COVID-19 tracheostomies and the incidence of COVID-19 infections amongst those health care workers involved in the procedure. An invitation to participate in an online survey tool (REDCap) was disseminated to all UK NHS departments involved in tracheostomy in mechanically ventilated COVID-19 patients via the Federation of Surgical Specialty Associations, it's subsidiary organisations and the Intensive Care Society. To date 78 hospitals have submitted 564 COVID-19 tracheostomy cases. Fifty-two percent (n=219/465) of patients who had undergone tracheostomy and were still alive, had been successfully weaned from mechanical ventilation at the point of completing the survey. The all cause in-hospital mortality following tracheostomy was 12% (n=62/530), with 3% of these (n=2/62) due to tracheostomy related complications and the remaining deaths due to COVID-19 related complications. Amongst 400 cases submitting data two weeks after the tracheostomy, no instance of COVID-19 infection amongst operators was recorded. FFP3 masks or Powered Air Purifying Respirators were used by operators in 100% of tracheostomies and a face visor or hood with face shield was available in 99% of cases. This interim report highlights early outcomes following tracheostomy in mechanically ventilated COVID-19 patients. Future reporting from COVIDTrach will include more detailed analysis at later timepoints using comparator groups in order to provide a more comprehensive assessment of tracheostomy in COVID-19.

event when the turning of the head towards the ipsilateral side as the lower jaw touches the anterior chest wall will not work effectively, the catheter can be easily pulled back and be re-inserted. We would support the development of this technology in two sectors: to increase the production and potential cost reduction, and the development of sensors that can be re-sterilized.
