Techniques in electromanometry of the upper esophageal sphincter
The various pull-through techniques used to measure pressure and length of the upper esophageal sphincter have not been studied in depth. Because of the importance of obtaining further information about these techniques, a group of 25 dogs was submitted to upper esophageal sphincter pressure and length measurements by three different pull-through techniques (two of the continuous type and one of the station type), each with three replications per animal, to determine possible differences among techniques. A single introduction provided reliable results, with no sequential effect of the measurements or of any one technique on resting pressure. However, each technique yielded different sphincter lengths, higher values being obtained when the continuous techniques were used
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
