To compare two brands of disposable plastic laryngoscope blades, Vital View plastic blades and Heine XP plastic blades, with the reusable Heine Classic+ Macintosh metal blades.
Prospective randomized, controlled, single-blinded study.
Operating room of a university-affiliated hospital.
519 patients without criteria for predicted difficult intubation, undergoing scheduled surgery during general anesthesia.
Patients were randomized to three groups according to laryngoscope blade brand.
Difficult tracheal intubation was evaluated by the Intubation Difficulty Scale (IDS) (IDS > 5 = procedure involving moderate to major difficulty).
The percentage of intubations with an IDS > 5 was 3.1% in Group M (metal blade group), 5.1% in Group V (Vital View plastic blade group), and 10.0% in Group H (Heine plastic blade group). A significant difference was noted between Groups M and H (P = 0.02) but not between Groups M and V.
Intubation may be more challenging when using Heine XP plastic blades but no significant difference exists between Vital-View plastic blades and Heine Classic+ metal blades.
比较两种一次性塑料喉镜叶片，即 Vital View 塑料叶片和 Heine XP 塑料叶片与可重复使用的 Heine Classic+ Macintosh 金属叶片。
前瞻性随机对照单盲研究。
一所大学附属医院的手术室。
519 名无预测性插管困难标准的患者，在全身麻醉下接受择期手术。
根据喉镜叶片品牌将患者随机分为三组。
插管困难程度通过插管难度量表（IDS）评估（IDS>5= 涉及中度至重度困难的操作）。
在 M 组（金属叶片组）中，IDS>5 的插管比例为 3.1%，在 V 组（Vital View 塑料叶片组）中为 5.1%，在 H 组（Heine 塑料叶片组）中为 10.0%。M 组和 H 组之间存在显著差异（P=0.02），但 M 组和 V 组之间无差异。
使用 Heine XP 塑料叶片进行插管可能更具挑战性，但 Vital-View 塑料叶片与 Heine Classic+ 金属叶片之间无显著差异。
