This study aimed to investigate the risk factors for postoperative arytenoid dislocation caused by endotracheal intubation.
From September 2014 to September 2016, the records of 28 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in type of anesthesia and surgery were chosen as the control (n = 56). Recorded data for all patients were demographics, smoking status, alcoholic status, operation time, and anesthesia procedures. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocations. Categorical variables were presented as frequencies and percentages, and were compared using the chi-square test. Continuous variables were expressed as means ± standard deviation and compared using the Student unpaired t test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis. Statistical significance was indicated by P < 0.05.
Twenty-eight patients demonstrating postoperative arytenoid dislocation (10 women and 18 men) were included, with a mean age of 55 ± 12 years. Sixteen patients (57.14%) had left arytenoid dislocation and 12 (42.86%) had right arytenoid dislocation. Univariate analysis indicated that body mass index (BMI) was associated with arytenoid dislocation (P < 0.01), and logistic regression analysis showed that BMI (P = 0.025) was an independent risk factor for postoperative arytenoid dislocation.
BMI might be the independent risk factor for postoperative arytenoid dislocation.
本研究旨在探讨气管插管所致术后杓状软骨脱位的危险因素。
回顾2014年9月至2016年9月期间28例有术后杓状软骨脱位病史患者的记录。选择麻醉类型和手术方式相匹配的患者作为对照（n = 56）。记录所有患者的人口统计学资料、吸烟状况、饮酒状况、手术时间和麻醉程序。对于杓状软骨脱位病例，我们进一步分析了左右杓状软骨脱位的发生率。分类变量以频率和百分比表示，并采用卡方检验进行比较。连续变量以均数±标准差表示，并采用非配对t检验进行比较。为确定杓状软骨脱位的预测因素，采用逻辑回归模型进行多因素分析。P < 0.05表示差异有统计学意义。
纳入28例术后出现杓状软骨脱位的患者（10例女性和18例男性），平均年龄为55±12岁。16例患者（57.14%）发生左侧杓状软骨脱位，12例（42.86%）发生右侧杓状软骨脱位。单因素分析表明，体重指数（BMI）与杓状软骨脱位有关（P < 0.01），逻辑回归分析显示BMI（P = 0.025）是术后杓状软骨脱位的独立危险因素。
BMI可能是术后杓状软骨脱位的独立危险因素。
