To evaluate risk factors associated with improper postoperative nasal Ring-Adair-Elwyn (RAE) tube depth.
We retrospectively enrolled 133 adult patients who were admitted to the intensive care unit (ICU) with the nasal RAE tube after head and neck surgery. Postoperative chest radiography was performed to confirm nasal RAE tube depth immediately after the patient was admitted to the ICU. Proper tube depth was defined as the tube tip between 2 and 7 cm above the carina. The patients were divided into the proper-depth group (78 patients) and the improper-depth group (55 patients). Patients' characteristics were collected. The risk factors for improper postoperative tube depth were assessed using logistic regression analysis.
All patients who showed improper tube depth had a shallow tube depth (the tube tip > 7 cm above the carina). Multivariable analysis revealed that tall stature [odds ratio (OR) 1.16; 95% confidence interval (CI) 1.08-1.25; P < 0.001], prolonged anesthesia duration (OR 1.16; 95% CI 1.02-1.32; P = 0.026), and right-sided surgical field as compared to the left (OR 0.36; 95% CI 0.14-0.93; P = 0.034) or median field (OR 0.25; 95% CI 0.07-0.85; P = 0.027) were risk factors associated with postoperative shallow tube depth.
Tall stature, prolonged anesthesia duration, and right-sided surgical field were independent risk factors for postoperative shallow nasal RAE tube depth.
评估与术后鼻环-Adair-Elwyn（RAE）管深度不当相关的危险因素。
我们回顾性纳入了 133 例因头颈部手术后入住重症监护病房（ICU）并带有鼻 RAE 管的成年患者。患者入住 ICU 后立即行胸部 X 线检查以确认鼻 RAE 管深度。合适的管深度定义为管尖端位于隆嵴上方 2 至 7 cm 之间。将患者分为合适深度组（78 例）和不合适深度组（55 例）。收集患者特征。使用逻辑回归分析评估术后管深度不当的危险因素。
所有显示管深度不当的患者均存在管深度过浅（管尖端高于隆嵴 7 cm 以上）。多变量分析显示，高身材[比值比（OR）1.16；95%置信区间（CI）1.08-1.25；P<0.001]、麻醉时间延长（OR 1.16；95% CI 1.02-1.32；P=0.026）以及右侧手术部位（与左侧相比，OR 0.36；95% CI 0.14-0.93；P=0.034）或中位部位（OR 0.25；95% CI 0.07-0.85；P=0.027）是与术后浅管深度相关的危险因素。
高身材、麻醉时间延长和右侧手术部位是术后鼻 RAE 管浅管深度的独立危险因素。
