To describe a practical method of aiding nasotracheal intubation in a cleft palate patient with previous pharyngoplasty using a suction catheter under tactile guidance. Problems of airway management in these patients are also discussed.
A 26-yr-old woman presented for elective Le Fort maxillary osteotomy. She had a history of cleft lip and palate and subsequent palatoplasty and pharyngeal flap. She had no symptoms of upper airway obstruction or obstructive sleep apnea. Preoperative examination revealed a hypernasal voice and patent nasal passages. Anesthesia was induced and the patient paralyzed. An attempt to pass a 6.5-mm cuffed endotracheal tube through the right nostril met with resistance. A suction catheter was introduced into the nostril, while a finger was positioned over the flap and the velopharyngeal port, until its tip rested against the flap, the catheter coiled and a small loop could be palpated past the patent velopharyngeal port. The catheter was then hooked into the oropharynx. The endotracheal tube was "railroaded" over it and advanced into the glottis. There was minimal bleeding and no desaturation during the procedure.
Preoperative determination of the type of pharyngoplasty is essential to understand the anatomy of the patent velopharyngeal port. A history of pharyngeal flap infection, hyponasal voice or upper airway obstruction suggests possible port stenosis. We describe a tactile guided technique that is useful and practical. Use of a flexible suction catheter of small external diameter minimizes the potential for trauma, bleeding and creation of false passages.
描述一种在先前已行咽成形术的腭裂患者中,在触觉引导下使用吸引导管辅助经鼻气管插管的实用方法。还讨论了这些患者气道管理的问题。
一名26岁女性因择期勒福上颌骨截骨术就诊。她有唇腭裂病史,随后接受了腭裂修复术和咽瓣手术。她没有上气道梗阻或阻塞性睡眠呼吸暂停的症状。术前检查显示有鼻音过重且鼻腔通畅。诱导麻醉并使患者肌肉松弛。尝试将一根6.5毫米带套囊的气管导管经右鼻孔插入时遇到阻力。将一根吸引导管插入鼻孔,同时用一根手指置于咽瓣和腭咽口上方,直到导管尖端抵住咽瓣,导管盘绕起来,可触及一个小环越过通畅的腭咽口。然后将导管钩入口咽。气管导管沿其“滑行”并推进至声门。手术过程中出血极少,且未出现血氧饱和度下降。
术前确定咽成形术的类型对于了解通畅的腭咽口的解剖结构至关重要。咽瓣感染史、鼻通气不足或上气道梗阻提示可能存在腭咽口狭窄。我们描述了一种实用的触觉引导技术。使用外径小的柔性吸引导管可将创伤、出血和形成假通道的可能性降至最低。
