RESUMO

Tracheostomy has been performed frequently in ventilator-dependent patients in intensive care unit (ICU). Some authors believe that early tracheostomy can reduce mechanical ventilation (MV) time and can provide other associated benefits. However, its influence on weaning from MV is not clear in pacients with traumatic brain injury (TBI). The aim of this study was to evaluate the influence of tracheostomy on MV weaning in TBI patients. It was a prospective and non interventional study; including 33 patients with TBI (GCS <10), aging between 14 and 80 years and that were submitted to a tracheostomy. The patients had been distributed into three groups: early tracheostomy (ET) (performed until 6th day of MV); intermediate tracheostomy (IT) (performed from the 7th to 11th day of MV) and late tracheostomy (LT) (performed after the 12th day of MV). Of the 33 evaluated patients, 28 were male and 5 female, aging 30.7 ± 14.0 years in ET group; 39.0 ± 18.4 years in IT group; and 37.7 ± 18.4 years in LT group. In the ET group, those patients with lower GCS and higher APACHE II at admission have shown a lesser hospital length of stay (HLOS); the IT group has shown a lesser HLOS in younger individuals and with lower APACHE II values. Regarding total MV time (orotracheal tube + tracheostomy), ET group has shown a lesser average time in relation to the other groups. However weaning times with tracheostomy alone were not different between groups. Also, pulmonary infection incidences have not been different between groups. Early tracheostomy can reduce total MV time and HLOS in patients with severe TBI, but it appears to have no influence on weaning time, incidence of pulmonary infection and mortality
