Background Endotracheal (ET) intubation is used to maintain the airway patency of patients during mechanical ventilation and is inserted at a particular depth into the trachea through the nose, mouth, or through an incision in the neck. The aim of our study was to validate the ideal length of an oral endotracheal tube (ETT) in the Asian population compared to Western standards. Methods Patient records with an oral ETT inserted between April 2011 and June 2015 in the Intensive Care Unit (ICU) of a hospital were retrospectively analyzed. The key variables included demographics, height, and ideal body weight of the patient, length of the oral ETT, and chest X-rays. Statistical analyses were performed using R software (https://cran.r-project.org/). Results There were 876 incidences of oral cuffed ETT insertions in 708 adult patients ≥ 18 years of age. The median ETT depth in all the ethnic groups (Chinese, Malay, Indians, and others) was 22 cm. The median depth of oral ETTs was 22 cm in males and 21 cm in females as compared to Western standards (males: P < 0.0001; females: P = 0.93). In ICU patients intubated with an ETT at an acceptable distance from the carina (2 - 5 cm), the median ETT depth was different in males (P < 0.0001) but was similar in females (P = 0.87). Conclusion We suggest that males and females in the Asian population, especially in South East Asia, should have their ETTs secured at the corner of mouth by at least 1 cm less in comparison to the Western population (22 cm in males and 20 cm in females).
气管内插管用于在机械通气期间维持患者气道通畅，通过鼻、口或颈部切口插入气管特定深度。我们研究的目的是验证与西方标准相比，亚洲人群口腔气管内导管（ETT）的理想长度。方法：回顾性分析2011年4月至2015年6月在一家医院重症监护病房（ICU）插入口腔ETT的患者记录。关键变量包括患者的人口统计学、身高、理想体重、口腔ETT长度和胸部X光片。使用R软件（https://cran.r-project.org/）进行统计分析。结果：708名年龄≥18岁的成年患者中有876例口腔带气囊ETT插入事件。所有种族（中国人、马来人、印度人和其他人）的ETT深度中位数为22厘米。与西方标准相比，男性口腔ETT深度中位数为22厘米，女性为21厘米（男性：P<0.0001；女性：P=0.93）。在气管隆突距离合适（2至5厘米）的ICU插管患者中，男性ETT深度中位数不同（P<0.0001），但女性相似（P=0.87）。结论：我们建议，与西方人群相比，亚洲人群尤其是东南亚的男性和女性，其ETT在口角处的固定长度应至少少1厘米（男性22厘米，女性20厘米）。
