地塞米松联合可视喉镜在气管插管中的应用

Influence of dexamethasone combined with video laryngoscope in tracheal intubation

目的探讨地塞米松注射液联合视宁康一次性可视喉镜在气管插管中预防术后气道并发症的应用效果。方法选择全身麻醉手术患者200例,按随机数字表法分为试验组和对照组各100例。试验组采用气管导管放入可视喉镜导管槽后,将地塞米松注射液5mg均匀地喷洒在气管导管前端1/3及套囊周围,平放可视喉镜不让药液溢出,放置5分钟,麻醉诱导后由主治以上麻醉医师插入气管导管。对照组将气管导管放入可视喉镜导管槽,麻醉诱导后同样由主治以上麻醉医师插入气管导管。记录患者导管留置时间,拔管后送入病房24h进行术后随访和纤维喉镜行咽喉部检查并记录。所有插管操作和术后评估均采用双盲法。结果试验组有4例发生术后声音嘶哑及咽喉痛,症状都较轻。对照组有12例发生,其中4例症状较重。纤维喉镜检查发现,试验组有3例咽喉部有轻微红肿,对照组有4例咽喉部红肿,症状都较试验组重。结论在全身麻醉气管插管中,地塞米松注射液的局部使用联合祝宁康一次性可视喉镜的应用,可以更有效地防治气管插管的并发症。

Objective To study the application of Dexamethasone injection combined with optic Ning-kang disposable video laryngoscope in tracheal intubation to prevente of postoperative airway complications.Methods 200 cases of patients with general anesthesia operation,were randomly divided into the test group and the control group with 100 cases in each group.The test group used of tracheal catheter into the video laryngoscope duct after dexamethasone injection 5mg was sprayed uniformly on the front end of the tracheal tube cuff around 1/3,and placed 5 minutes.Retention time of intubation and adverse reaction were recorded.Results The test group had 4 cases of hoarseness and sore throat after operation,12 cases of the control group.The test group 3 cases with slight swelling,4 cases of the control group.Conclusion In tracheal intubation general anesthesia,local dexamethasone injection may be more effective to reduce the complications of tracheal intubation.
