Background:
Increased anesthesia time may lead to respiratory complications in patients receiving tracheostomy, which contributes to patient morbidity.
Methods:
The American College of Surgeon's National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for cases of planned tracheostomy (CPT 31600) from 2005 to 2012. Patients were stratified into quintiles based on anesthesia duration. Pearson's chi square, Fischer's exact test, one-way ANOVA, and multivariate regression were used to determine the association between patient characteristics with pneumonia and ventilator dependence.
Results:
Out of 752 patients, 83 patients experienced post-operative pneumonia, and 166 experienced ventilator dependence. Following multivariate regression analysis, anesthesia quintiles were not significantly associated with pneumonia or ventilator dependence. Age (OR 1.03, 95% CI 1.00-1.05, P = .032), dyspnea (OR 2.21, 95% CI 1.18-4.13; P = .013), pre-operative ventilator dependence (OR 3.08, 95% CI 1.19-7.98; P = .020), and sepsis (OR 6.68, 95% CI 3.19-14.0; P < .001) remained as significant predictors of post-operative ventilator dependence.
Conclusions:
Faster may not be better-- prolonged anesthesia time does not increase the risk of post-operative pneumonia or ventilator dependence in patients receiving a planned tracheostomy in the operating room.

Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
