IntroductionNumerous uncertainties remain concerning the place of tracheostomy in intensive care. Reluctance to perform tracheostomy is common, particularly in the presence of pre-existing chronic respiratory insufficiency (CRI), but some data suggest there may be benefits. The objective of this study was to evaluate the influence of tracheostomy on mortality in both intensive care and hospital, and to study the role of pre-existing CRI.Material And MethodsIn a retrospective study of the records of 2901 patients admitted over a period of 5 years 882 were identified who had been intubated and ventilated. 127 patients who had had tracheostomies (T+) were compared with 755 who had not (T-), and with a sub-group of T- patients (T-app) matched for severity on admission (SAPSII).ResultsICU and hospital mortality were significantly less in the T+ than the T-patients (28 vs 52% and 42 vs 59%) and the duration of stay was longer. This was equally true when matched for severity on admission when T+ were compared with T app (28 vs 49% and 42 vs 59%). Pre-existing CRI did not influence the outcomes of the tracheostomised patients, regardless of whether the CRI was obstructive, restrictive or neuro-muscular.ConclusionsTracheostomy can, in certain groups of artificially ventilated patients and in certain care settings, be associated with a reduction in hospital mortality.
