RESUMO
The use of endotracheal intubation for respiratory support of critically ill patients has become a standard life saving form of therapy. Most complications of intubation become apparent only after extubation which may manifest in the early or late post extubation period. This study was undertaken to demonstrate the occurrence and extent of laryngotracheal injuries in intubated patients by performing flexible fibreoptic bronchoscopy at varying intervals following extubation. It was found that initial laryngoscopy findings were more pronounced in patients intubated for upto twelve days. Furthermore, it was also observed that the initial laryngeal pathology seen on fibreoptic laryngoscopy was not an accurate predictor for the development of adverse post extubation sequelae. Maxillary sinusitis developed significantly in patients intubated nasally. Routine flexible fibreoptic examination of the larynx following extubation is recommended for early detection of granulomas, synechia of vocal cords and vocal cord immobility to prevent troublesome sequelae.
