LESOES PRECOCES DA INTUBACAO ENDOTRAQUEAL

The authors studied the early lesions of laryngotracheal mucosa following intubation in 30 dogs who were intubated with high complacent canula during the period of 4 hours. After this period, biopsies of vocal cord, aritenois, cricoid and tracheal rings were performed. The most frequent histological findings were neutrophils and mononuclear inflammatory cell infiltration into the corion, vascular congestion and necrosis of epithelial cells. Based in these findings the authors recommend the use of canula with balonets of high complacence and the endoscopic follow up of the patients after extubation.
