The purpose of this study is to describe all degrees of endotracheal intubation difficulty among patients attended by eight anesthesiologists during routine surgery over a six-month period. Airway characteristics were routinely assessed preoperatively, according to the anesthesiologists' usual practice.
Difficult tracheal intubation was evaluated by the Intubation Difficulty Scale (IDS), a quantitative score based on seven variables. An IDS value of 0 is consistent with a procedure without difficulty, and an IDS > 5 with a procedure involving moderate to major difficulty.
For 1171 patients undergoing tracheal intubation, IDS was 0 in 55%, and greater than 5 in 8% of cases. External laryngeal pressure, repositioning the patient and added use of a stylet were the most frequent methods chosen to facilitate tracheal intubation.
There was a high incidence (37%) of minor difficulties encountered during routine surgery.
本研究的目的是描述在六个月的常规手术期间，八位麻醉医生所接诊患者的各种程度的气管插管困难情况。根据麻醉医生的常规做法，术前常规评估气道特征。
采用插管困难量表（IDS）评估气管插管困难程度，该量表基于七个变量得出定量评分。IDS值为0表示操作无困难，IDS>5表示操作存在中度至重度困难。
在1171例接受气管插管的患者中，55%的患者IDS为0，8%的患者IDS大于5。外部喉压、调整患者体位以及额外使用管芯是最常选择的促进气管插管的方法。
在常规手术中遇到轻度困难的发生率较高（37%）。
