实测门齿到气管隆突的距离在肺外科手术双腔支气管导管插管中的应用

Application of Actual Distance between Incisor and Trachea Carina in Double-lumen Endobronchial Tube Intubation

结果1086例中71例出现并发症，其中局部黏膜损伤37例，门齿损伤8例，舌损伤13例，颞颌关节损伤9例，术中窦性心动过缓4例。

Results Among the 1,086 , 71 cases suffered from complications , which included 37 cases of local mucous injury , eight of incisor tooth injury , 13 of tongue injury , and nine of temporomandibular joint injury . Also , there were four cases of sinus bradycardia .

结论采用实测门齿到隆突的距离指导dlt插管操作简便，安全可靠，适用于基层医院。

Conclusion actual distance between incisor teeth and trachea carina guiding DLT intubation is easily manipulcated and safe , which is worthy extending in pneumosurgery operation , especially in primary level hospitals .

选40日龄的雌性大鼠以150ppm的高氟水喂饲60日，造成大鼠慢性氟中毒，表现为血氟升高及门齿斑釉的出现。当大鼠100日龄时与正常雄鼠交配。

Female rats at the age of 40 days were fed with high fluoride ( 150ppm ) drinking water for 60 days .

并发症：发生门齿移位2例，颈部皮下气肿1例。

The postoperative complications are : dentes primoris moving in 2 cases and aerodermectasia in 1 case .

譬如，牙齿更为原始，有大的犬齿和非常合适的门齿。

For example , the teeth are more primitive . There are large canines and unusually shaped incisors .

在放射治疗前、后及治疗半年后分别对两组病人的门齿间距进行测量。

The distance between the incisor teeth in the two groups was measured before and immediately , 6 months after radiotherapy .

丁村人形态介于现代人和猿人之间，其门齿具铲形特征，与现代蒙古人相近。

Shape between the small village between the modern and the ape-man , their shovel-shaped incisors with features similar to those of modern Mongolians .

两个民族铲型门齿率、凸型鼻梁率、突颏率、直发率存在显著差异。

The index of front tooth type , nasal profile , chin projection and hair form mentioned above showed significant deviation between the two nationalities .

咬肌能使门齿咬合时发出55磅的力，臼齿则能发出200磅的力。

It can close the teeth with a force as great as 55 pounds ( 25 kilograms ) on the incisors or 200 pounds ( 91 kilograms ) on the molars .

结果实验1个月后，实验组动物股骨与门齿氟含量均远低于阳性对照组。

Results After one month of being treated with the abstract of pearl , contents of fluoride in the femora and teeth of the rats in the experimental gourp were significantly lower compared with the positive control .
