Abstract：
UNASSIGNED: The head-elevated laryngoscopy position (HELP) and a 25° backup have been proposed to enhance glottic visualisation, yet concerns about ergonomic discomfort hinder their widespread adoption. This study compares the comfort and posture adopted by anaesthesiologists while performing laryngoscopy and tracheal intubation with patients in HELP while in a supine position or with 25° backup.
UNASSIGNED: The study included 48 patients aged 18-60 years with normal airways and 12 experienced anaesthesiologists. Patients were randomised into two groups using permuted block randomisation. Anaesthesiologists performed laryngoscopy and intubation in supine HELP and 25° backup HELP positions. Anaesthesiologist\'s posture was determined by measuring the angles of neck, wrist, elbow, back and knee joints, which were compared using Student\'s t-test, and subjective comfort assessed on a Likert scale was compared using the Chi-square test. As mentioned by the anaesthesiologist, Cormack- Lehane grading was also noted and compared using a Chi-square test between groups, taking a P value <0.05 as significant.
UNASSIGNED: Both positions demonstrated comparable anaesthesiologist posture (P = 0.919) and comfort (P = 0.644). However, the 25° backup HELP positions significantly improved Cormack-Lehane grades, with 68% achieving grade 1 compared to 31% in the supine HELP group (P = 0.012). Haemodynamic stability and tracheal intubation time showed no significant differences between the groups (P = 0.475 and 0.117, respectively), and no complications were reported in either group.
UNASSIGNED: Anaesthesiologists\' posture and comfort during laryngoscopy and tracheal intubation are similar between supine and 25° backup in patients with easy airways.

摘要：
■已经提出了头部升高的喉镜检查位置（HELP）和25°备份来增强声门可视化，然而，对人体工程学不适的担忧阻碍了它们的广泛采用。这项研究比较了麻醉师在仰卧位或25°备份的HELP患者进行喉镜检查和气管插管时采用的舒适度和姿势。
■该研究包括48名年龄在18-60岁之间、气道正常的患者和12名经验丰富的麻醉师。使用置换区组随机化将患者随机分为两组。麻醉医师在仰卧HELP和25°备用HELP位置进行了喉镜检查和插管。麻醉师的姿势是通过测量颈部的角度来确定的，手腕,弯头,背部和膝关节，使用学生t检验进行比较，使用卡方检验比较了在李克特量表上评估的主观舒适度。正如麻醉师提到的，Cormack-Lehane分级也被注意到，并在组间使用卡方检验进行比较。以P值<0.05为显著。
■两种姿势均显示出相当的麻醉师姿势（P=0.919）和舒适度（P=0.644）。然而,25°备用帮助位置显着提高了Cormack-Lehane成绩，其中68%达到1级，而仰卧HELP组为31%（P=0.012）。两组间血流动力学稳定性和气管插管时间差异无统计学意义(P=0.475和0.117)。两组均未出现并发症.
■麻醉医师\'在喉镜检查和气管插管期间的姿势和舒适度在仰卧和25°备份之间相似。
