Does Tracheostomy Affect the Mortality and Morbidity Rate After Cardiac Surgery?

Abstract

Objective: This retrospective study aims to investigate the timing and outcomes of tracheostomy,

mortality and morbidity rates, length of in-hospital and cardiovascular intensive care unit (ICU)

stay in patients with post-cardiac surgery.

Patients and Methods: Between October 2014 and October 2016, a total of 401 cardiac surgery

were performed in our hospital. Thirteen patients who needed post-operative prolong

ventilation (7 female; 6 male; mean age was 67.7 ± 9.8 years; range 47 to 86 years) undergoing

tracheostomy procedure, were included in this retrospective study.

Results: The mean intubation time between the cardiac surgery and tracheostomy was 14.5±2.9

days (range 11 to 21). The mean intensive care unit stay time was 27.4 ±9.4 days (range 12 to

49) and the mean in-hospital stay was 43.1±23.7 days (range 16-91). 8 patients passed away

and the in-hospital mortality rate was 61%. After a mean follow-up of 161.4±151.1 days (range

57 to 417), 3 patients (7%) passed away while one patient (7%) was decannulated. One patient

(7%) is currently under follow-up at home using a home-type ventilator. Regarding patients

who passed away after discharge, the overall mortality rate was 84.6%. In addition, the number

of extubation attempts was 0.65±1.12 (range 0 to 4).

Conclusion: Tracheostomy is performed in need of prolonged mechanical ventilation in

patients with post cardiac surgery. We thought that tracheostomy does not decrease the

incidence of nosocomial pneumonia in hospital/ICU stay and morbidity/mortality as expected.
