气管插管术后短时发声改变常认为是声带创伤所致,作者用功能检查研究此变化的特征及其原因。实验组(EG)为门诊气管插管全麻妇科手术10例;对照组(CG)10例非手术病例。年龄匹配分别平均33岁和33.6岁。发声功能检查两次相隔约8小时,EG 在术晨和术后离院时。基频(F_0)和频率微扰(J)分析:F~0
Short-term vocal changes after tracheal intubation are often thought to be caused by vocal cord trauma, the authors use functional tests to investigate the characteristics of this change and its causes. The experimental group (EG) was outpatient tracheal intubation general anesthesia gynecological surgery in 10 cases; control group (CG) 10 cases of non-surgical cases. Age matching average 33 years old and 33.6 years old respectively. Vocal function tests were separated by approximately 8 hours between two sessions and EG was taken at the end of the morning and after surgery. Fundamental frequency (F_0) and frequency perturbation (J) Analysis: F ~ 0
