作者对经复苏术死亡的12具尸喉进行了研究。死者年龄自35～85岁,男7例,女5例。1例未插管作对照,其他11例均经带低压气囊之聚氯乙烯导管插管,为期3～10天,平均5.7天。此组病例中有1例插管9天后行气管切开术,术后6天死亡,其他患者之导管保留至死。取下之喉用福尔马林固定,经纵行裂开肉眼观察后,通过环杓关节及杓间区垂直方向切片进行组织学研究。 11例经插管的喉皆有损伤,对照的1例无任何病变。损伤主要在喉后部。全部病例双声带窦下面呈对称性溃疡;声门下对称性溃疡4例;杓间区溃疡3例;杓前面及舌骨上会厌溃疡各1例;会厌根部溃疡2例;环状软骨弓溶解1例;气管损伤6例。组织学检查见粘膜溃疡有纤维素覆盖,
The authors studied 12 corpse throats that died of resuscitation. The deceased age from 35 to 85 years old, 7 males and 5 females. One case was not intubated for the control, the other 11 cases were catheterized with low pressure balloon catheter, a period of 3 to 10 days, an average of 5.7 days. One patient in this group had a tracheotomy 9 days after intubation, died 6 days after the procedure, and catheters in other patients remained dead. Hypothyroidism was fixed with formalin. Histological observation was performed by longitudinal dissection and histology was performed by vertical sectioning of the cricoid joint and intertuberal region. 11 cases of intubated throat Jieyou injury, a control without any lesions. Damage mainly in the posterior larynx. In all cases, there were symmetrical ulcers in the bilateral vocal fold sinus, 4 cases of subglottic symmetric ulcer, 3 cases of ulcer in the intertuberal region, 1 case of epiglottis ulcer in front of phlegm and 2 cases of epiglottis root ulcer in 2 cases. Tracheal injury in 6 cases. Histological examination of mucosal ulcers were covered with cellulose,
