Impact of Tracheostomy Timing on Outcomes After Cardiovascular Surgery

This study aimed to investigate whether tracheostomy timing in patients undergoing cardiac surgery had an impact on outcomes.

Retrospective, observational study.

Single-center university hospital.

Patients requiring tracheostomy among a total of 961 patients who underwent cardiovascular surgery via a median sternotomy from January 2014 to March 2021.

Early versus late tracheostomy.

During the study period, tracheostomy was performed in 28 patients (2.9%). According to tracheostomy timing, postoperative day seven was chosen as the cutoff to define early (≤seven days) and late (>seven days) tracheostomy. Patients in the early-tracheostomy group had a significantly shorter ventilation time after tracheostomy compared with the late-tracheostomy group (p = 0.039), and early tracheostomy resulted in a reduction in total ventilation time (p = 0.001). The incidence of pressure ulcers was significantly lower in the early-tracheostomy group compared with the late- tracheostomy group. There was a higher tracheal tube removal rate in the early-tracheostomy group compared with the late-tracheostomy group (p = 0.0007). The one-year survival rate in the early- and late-tracheostomy groups was 65% and 31%, respectively. The long-term mortality rate was significantly lower in the early-tracheostomy group compared with the late- tracheostomy group (p = 0.04).
