A modified tracheostomy was designed for respiratory function studies in sheep. Our primary objective was to prevent development of severe tracheal stenosis, which was observed with procedures designed for canine tracheostomy. Surgery consisted of an intercartilaginous tracheal slit, with apposition of tracheal mucosa to skin. This procedure produced no significant stenosis at postmortem evaluation in 19 sheep. In contrast, 5 of 20 sheep with excision of the ventral 1/3 of the third and fourth tracheal rings, had severe tracheal stenosis.
设计了一种改良的气管切开术用于绵羊的呼吸功能研究。我们的主要目标是防止严重气管狭窄的发生，而在用于犬气管切开术的操作中观察到了这种情况。手术包括气管软骨间切开，并将气管黏膜与皮肤对合。在19只绵羊的尸检评估中，该手术未产生明显狭窄。相比之下，在20只切除第三和第四气管环腹侧1/3的绵羊中，有5只出现了严重的气管狭窄。
