We are presenting a case of a 26 year old healthy male, who came with gradual worsening of dyspnoea following prolonged intubation and ventilation, after a road traffic accident five months back. On arrival in ER, he was hypoxaemic with severe respiratory distress. He was transferred to the operation room (OR) for emergency tracheostomy. During the transfer, he was placed in an upright position with oxygen at 15 L/M. In the OR, anaesthesia was induced with sevoflurane gradually. Direct laryngoscopy was done which revealed normal vocal cords. A size 4.00 mm ID endotracheal tube was impossible to pass more than 1-2 cm distal to vocal cords. Due to a large leak, size 8 tube was passed below the cords and cuff was inflated slightly to reduce air leak. Oxygen saturation dropped to 95-96% and surgeon was asked to start tracheostomy. Findings included an almost complete subglottic stenosis, 2 cm below the vocal cords. A tracheostomy tube was inserted below the stenotic lesion which was followed by direct laryngoscopy.
我们现报告一例26岁健康男性病例,该患者在五个月前发生道路交通事故后,经历了长时间插管和通气,随后出现呼吸困难逐渐加重的情况。到达急诊室时,他存在低氧血症并伴有严重的呼吸窘迫。他被转至手术室进行紧急气管切开术。在转运过程中,他被置于直立位,给予15升/分钟的氧气。在手术室中,逐渐用七氟醚诱导麻醉。进行直接喉镜检查,结果显示声带正常。一根内径4.00毫米的气管导管无法通过声带远端超过1 - 2厘米。由于漏气严重,将8号导管通过声带下方,并稍微充盈气囊以减少漏气。氧饱和度降至95 - 96%,于是要求外科医生开始进行气管切开术。检查发现声门下几乎完全狭窄,位于声带下方2厘米处。在狭窄病变下方插入一根气管切开导管,随后再次进行直接喉镜检查。
