BackgroundTracheostomy after cardiac operation through a median sternotomy is believed to increase the risk of mediastinitis, leading to debate as to whether early tracheostomy is safe in these patients.MethodsA record search of patients undergoing cardiac operation through median sternotomy was done. Day and duration of tracheostomy were correlated to day of positive bacteriological evidence and clinical outcome for the patient. The method of tracheostomy was also recorded.ResultsOf 174 cases, 4 patients had mediastinitis, 3 before tracheostomy was performed. Of these three patients, 2 survived and the third died of multiorgan failure 46 days after the procedure. The fourth patient, on immunosuppressive therapy for severe rheumatoid arthritis and pulmonary fibrosis, had tracheostomy performed at primary operation, developed fatal mediastinitis after 6 days, and died 18 days postoperatively of multiorgan failure. Of the tracheostomies performed, 24 (14%) were percutaneous, and 110 (63%) were achieved using standard surgical techniques (in 40 cases type was unrecorded). In 72 cases (41%), tracheostomy was performed on or before day 7, 11 (6%) being performed before 48 hours. Mortality occurred in 38 (22%).ConclusionsThere is no demonstrable relationship between early tracheostomy and mediastinitis in median sternotomy patients.
