Challenges of tracheostomy in COVID-19 patients in a tertiary centre in inner city London

The rapid global spread of SARS-CoV-2, the causative agent of COVID-19, has dominated healthcare services, with exponential numbers requiring mechanical ventilation in the intensive care unit (ICU). Tracheostomy facilitates respiratory and sedative weaning but risks potential viral transmission. This study reviewed the tracheostomy provision, techniques, and outcomes for a single-centre prospective cohort during the resource-pressured COVID-19 period. Seventy-two of 176 patients underwent tracheostomy at a median 17 days: 44 surgical (open), 28 percutaneous. Their median age was 58 years, the male to female ratio was 2.4:1, 78% were of BAME backgrounds, 76% had a BMI ≥ 25 kg/m(2), and 65% had ≥2 major co-morbidities. Seventy-nine percent of patients were weaned from sedation at a median 2 days, 61% were weaned from mechanical ventilation at a median 10 days, 39% were discharged from the ICU at a median 11.5 days, and 19% were discharged home at a median 24 days. All patients survived the procedure. The mortality rate was 9.7% at a median 12 days. No clinician reported COVID-19 symptoms within 14 days of the procedure. The role of tracheostomy in COVID-19 is currently unclear. Delivery of tracheostomy by maxillofacial surgeons relieved the workload pressure from ICU clinicians. The choice of technique was influenced by the patient and resource factors, resulting in a mixed cohort of open and percutaneous tracheostomy in COVID-19 patients. Preliminary data suggest that open tracheostomy is as favourable as percutaneous tracheostomy for COVID-19 patients, and is safe for clinicians.
