Early tracheostomy after cardiac surgery improves intermediate- and long-term survival.
Medicina intensiva(2023)
Abstract
OBJECTIVE:Complicated post-cardiac surgery course, can lead to both prolonged ICU stay and ventilation, and may require a tracheostomy. This study represents the single-center experience with post-cardiac surgery tracheostomy. The aim of this study was to assess the timing of tracheostomy as a risk factor for early, intermediate, and late mortality. The study's second aim was to assess the incidence of both superficial and deep sternal wound infections.
DESIGN:Retrospective study of prospectively collected data.
SETTING:Tertiary hospital.
PATIENTS:Patients were divided into 3 groups, according to the timing of tracheostomy; early (4-10 days); intermediate (11-20 days) and late (≥21 days).
INTERVENTIONS:None.
MAIN VARIABLES OF INTEREST:The primary outcomes were early, intermediate, and long-term mortality. The secondary outcome was the incidence of sternal wound infection.
RESULTS:During the 17-year study period, 12,782 patients underwent cardiac surgery, of whom 407 (3.18%) required postoperative tracheostomy. 147 (36.1%) had early, 195 (47.9%) intermediate, and 65 (16%) had a late tracheostomy. Early, 30-day, and in-hospital mortality was similar for all groups. However, patients, who underwent early- and intermediate tracheostomy, demonstrated statistically significant lower mortality after 1- and 5-year (42.8%; 57.4%; 64.6%; and 55.8%; 68.7%; 75.4%, respectively; P < .001). Cox model demonstrated age [1.025 (1.014-1.036)] and timing of tracheostomy [0.315 (0.159-0.757)] had significant impacts on mortality.
CONCLUSIONS:This study demonstrates a relationship between the timing of tracheostomy after cardiac surgery and mortality: early tracheostomy (within 4-10 days of mechanical ventilation) is associated with better intermediate- and long-term survival.
