| 目的：比较可视喉镜与MCcoy喉镜用于神经外科声门显露困难患者气管插管的效果。方法:择期行神经外科经口气管插管的全麻患者60例，Mallanpati 分级III—IV级，采用随机数字表法，将患者随机分为可视喉镜组（I组，n=30）和MCcoy喉镜组（II组，n=30），两组分别记录声门显露时间、气管导管时间、气管插管情况和术后随访患者咽喉疼痛发生情况。朮中,观察声门显露时间、气管插管置入时间、一次气管插管成功率，术后随访患者咽喉疼痛发生情况。记录气管插管期间血流动力学情况，高血压、心动过速和低氧血症的情况。结果：两组相比，在声门显露时间、气管导管置入时间差异有显著性意义（p<0.05）,咽喉疼痛可视喉镜组5例，MCcoy喉镜组6例，环状软骨按压MCcoy喉镜组11例，可视喉镜组无环状软骨按压。一次性置管成功率可视软镜组100%，MCcoy喉镜组有两例二次插管。气管插管期间可视喉镜组血流动力学稳定，均未发生高血压、心动过速和低氧血症的情况。MCcoy喉镜组有3例高血压、心动过速。无低氧血症的情况。结论：可视软喉镜有助于神经外科声门显露困难者声门显露，且可提高气管插管的成功几率。减少了对血流动力学的影响，减轻了气管插管对颅内压的影响。 |

| Abstract: |
| Objective To compare the efficacy of vedio soft lens and MCcoy laryngscope for difficult glottis exposure.Methods sixty aldult patiends scheduled for eletive surgery under general anesthesia whose glottis exposure difficult.were randomized into 2 groups (n=30,each),group edio soft lens and group MCcoy laryngscope,The glottis exposure time, intubating conditions time from exposure of glottis to completion of tracheal intubation and incidence of postoperative sore throat and throat bleeding were recorded and compared bettween the 2 gyoups.Results Compare with group edio soft lens,group MCcoy laryngscope the glottis exposure time was siginificantly longer（p<0.05） , the time from exposure of glottis to completion of tracheal intubation longer.（p<0.05）sore throat and throat bleeding between the 2 groups.Second attempt 2 times in group MCcoy laryngscope.Hypertension and tachycardia were founded at group MCcoy laryngscope.Conclusion vedio soft lens is superior to MCcoy laryngscope in the management of difficult intubation in term of glottis exposure and success rate of tracheal intubation at first attempt |
