Abstract

Introduction: Mechanical ventilation of patients may be accomplished by either translaryngeal intubation or tracheostomy. Although numerous intensive care unit (ICU) studies have compared various outcomes between the two techniques, no definitive consensus indicates that tracheostomy is superior. Comparable studies have not been performed in a respiratory care center (RCC) setting.Methods: This was a retrospective observational study of 985 tracheostomy and 227 translaryngeal intubated patients who received treatment in a 24-bed RCC between November 1999 and December 2005. Treatment and mortality outcomes were compared between tracheostomized and translaryngeal intubated patients, and the factors associated with positive outcomes in all patients were determined.Results: Duration of RCC (22 vs. 14 days) and total hospital stay (82 vs. 64 days) and total mechanical ventilation days (53 vs. 41 days) were significantly longer in tracheostomized patients (all P < 0.05). The rate of in-hospital mortality was significantly higher in the translaryngeal group (45% vs. 31%;P < 0.05). No significant differences were found in weaning success between the groups (both were >55%) or in RCC mortality. Because of significant baseline between-group heterogeneity, case-match analysis was performed. This analysis confirmed the whole cohort findings, except for the fact that a trend for in-hospital mortality was noted to be higher in the translaryngeal group (P = 0.08). Stepwise logistic regression revealed that patients with a lower median severity of disease (APACHE II score <18) who were properly nourished (albumin >2.5 g/dl) or had normal metabolism (BUN <40 mg/dl) were more likely to be successfully weaned and survive (all P < 0.05). Patients who were tracheostomized were also significantly more likely to survive (P < 0.05). Conclusions: These findings suggest that the type of mechanical ventilation does not appear to be an important determinant of weaning success in an RCC setting. Focused care administered by experienced providers may be more important for facilitating weaning success than the ventilation method used. However, our findings do suggest that tracheostomy may increase the likelihood of patient survival.
