摘要
目的通过尸体解剖观测环甲膜的形态位置及环甲膜穿刺术有关数值,为临床环甲膜穿刺急救提供解剖学依据。方法对20例正常成人尸体(男16例,女4例)喉标本进行观察,依次进行环甲膜模拟穿刺术,并对环甲膜具有重要临床意义的解剖学数据进行测量。结果皮肤至环甲膜内面黏膜的厚度为(4.0±0.5)mm,环甲膜穿刺最小深度为(7.0±0.5)mm,穿刺最大深度为(28.6±2.5)mm;环甲膜略呈倒置的等腰三角形状,底(上宽)为(16.1±1.2)mm,顶(下宽)为(6.2±2.8)mm,高(前角的下缘至环状软骨弓上缘中点的距离,即环甲正中韧带高度)为(11.0±1.0)mm。结论成人经皮进行环甲膜穿刺急救时,可用1~3枚直径为3mm左右的穿刺针,一般穿刺深度在(7.0±0.5)^(28.6±2.5)mm之间,不宜过浅或过深,以防并发症的发生。
Objective To observe shape and location of the crico-thyroid membrane and thyrocricocen-tesis by autopsy, and provide anatomical basis for emergency in clinical application. Methods 20 throat essays of normal adult body （16 males ,4 females） were observed, crico-thyroid membrane simulation puncture in order, and measure crico-thyroid membrane that has an important clinical significance of anatomical data. Results From crico-thyroid membrane to the skin surface of the mucous membrane thickness （4. 0 ±0.5） mm, thyro-cricoid puncture minimum depth （7. 0±0. 5） irma,maximum depth of puncture （28.6±2.5） mm; crico-thyroid membrane,such as the slightly inverted Lumbar triangular shape at the end of （W） （16. 1±1.2） mm,the top （W） （6.2±2. 8） mm,height （the lower edge angle to the upper edge of the cricoid cartilage arch midpoint of the range, that is, a ring Median ligament height） （ 11.0±1.0 ） mm. Conclusion By Percuta- neous Thyrocricocentesis in adults for emergency, use transfixion pins at 1-3 about 3 mm in diameter, puncture depth in general between （7. 0±0. 5 ） to （ 28.6±2. 5 ） mm, and should not be too deep Or too shallow, to prevent complications.
