Teaching airway management continues to be of high importance to the anesthesiologist, since the care of each individual patient depends on the expertise, training and knowledge of the anesthetist with different airway devices, techniques and algorithms. The aim of our study was to compare intubation performed by resident anesthesiologists in training, under senior supervision, using Truview EVO2 (Group 1) or Macintosh blade (Group 2) in a group of adult patients undergoing elective surgery.
This was a pilot prospective study. Thirty patients who were scheduled for surgery under general anesthesia were randomized into two groups. In Group 1, intubation was performed by using the Truview EVO2, and in Group 2 intubation was performed by using the Macintosh blade. Mallampati score, thyromental distance and neck mobility were recorded for each patient. The exclusion criteria included a Mallampati score =or<2 and a Patil distance >6 cm. The time of intubation and any occurrence of complications were recorded.
Intubation was always successful on the first attempt in Group 1, while it failed for 46.7% of patients in Group 2 (P=0.006). The time of intubation was not different between the two groups. No complications were recorded for Group 1 (Truview), while seven were reported in Group 2 (Macintosh) (P=0.003).
The resident managed to intubate all patients on the first attempt with the Truview, which led to a lower incidence of complications. Despite the exiguity of the population in the study, Truview EVO2 and other videolaryngoscopes can be considered to be useful tools in training resident anesthesiologists in elective intubation.
气道管理教学对于麻醉师来说仍然非常重要，因为每位患者的护理都取决于麻醉师使用不同的气道设备、技术和算法的专业知识、培训和知识。我们的研究目的是比较在高级监督下接受培训的住院麻醉师在一组接受择期手术的成年患者中使用 Truview EVO2（第 1 组）或 Macintosh 刀片（第 2 组）进行插管的情况。
这是一项前瞻性试点研究。将 30 名计划在全身麻醉下接受手术的患者随机分为两组。在第 1 组中，使用 Truview EVO2 进行插管，在第 2 组中，使用 Macintosh 刀片进行插管。记录每位患者的 Mallampati 评分、甲状软骨至下颌骨距离和颈部活动度。排除标准包括 Mallampati 评分为 =or<2 和 Patil 距离 >6 cm。记录插管时间和任何并发症的发生情况。
第 1 组的插管始终在第一次尝试时成功，而第 2 组有 46.7%的患者插管失败（P=0.006）。两组的插管时间无差异。第 1 组（Truview）未记录到任何并发症，而第 2 组（Macintosh）报告了 7 例并发症（P=0.003）。
住院医师使用 Truview 成功地对所有患者进行了第一次尝试插管，这导致并发症的发生率降低。尽管研究中的人群数量很少，但 Truview EVO2 和其他视频喉镜可以被认为是培训住院医师进行择期插管的有用工具。
