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

Abstract

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.

Tracheostomy in Adult Intensive Care Unit: An ISCCM Expert Panel Practice Recommendations

“…Patients undergoing early tracheostomy after decompressive craniectomy 39 had decreased hospital mortality (p = 0.013). Tracheostomy in cardiac surgical patients 21,46 have not shown any benefit in terms of mortality at varying time frames whereas a retrospective review of prospective data conducted by Devarajan et al 30 concluded that early tracheostomy is associated with reduced in hospital mortality (21.1% vs 40.4%, p = 0.002)…”

Essential Characteristics of Social and Legal Competence of Future Engineers at Technical University

“…Terekhov identifies three components of socio-legal competence: the cognitive component of socio-legal competence includes a certain level of legal knowledge, as well as willingness and ability to master this knowledge. 2. the procedural component of socio-legal competence implies the knowledge and abilities that are necessary for a potential legal act to realize the opportunities existing within the framework of this institutional order; the motivational component of socio-legal competence implies the presence of skills and internal attitudes necessary to supplement knowledge of the legal system and methods of solving emerging problems in the legal sphere with practical activity of the individual [13][14][15].…”
