The sniffing position is considered to be the standard position for direct laryngoscopic viewing. This crossover study evaluated age and gender as variables in comparing the benefits of the sniffing position over simple head extension for laryngeal view during direct laryngoscopy.
Laryngoscopy with a curved blade was performed on 200 anesthetized adults (100 males, 100 females) presenting for routine elective surgery. Glottic visualization was assessed by using the percentage of glottic opening (POGO) score in both simple extension and sniffing positions without the aid of the assistant or external laryngeal manipulation. Each gender group was divided into a younger group (< 50 years) and an older group (≥ 50 years). POGO scores were compared between both positions within each group.
Mean (SD) POGO scores increased significantly only in younger male patients from 43% (39%) in the head extension position to 76% (30%) in the sniffing position.
The sniffing position seems to be advantageous for getting a better laryngeal view during laryngoscopy for tracheal intubation in adult male patients less than 50 years old.
嗅物位被认为是直接喉镜检查的标准体位。这项交叉研究评估了年龄和性别这两个变量，以比较在直接喉镜检查期间，嗅物位相较于单纯头部伸展在观察喉部方面的优势。
对200例接受常规择期手术的成年麻醉患者（100例男性，100例女性）进行弯形喉镜检查。在不借助助手或外部喉部操作的情况下，通过声门开口百分比（POGO）评分评估在单纯伸展位和嗅物位时的声门可视情况。每个性别组又分为较年轻组（<50岁）和较年长组（≥50岁）。比较每组内两个体位之间的POGO评分。
仅在较年轻男性患者中，平均（标准差）POGO评分显著提高，从头部伸展位的43%（39%）增至嗅物位的76%（30%）。
对于年龄小于50岁的成年男性患者，在气管插管的喉镜检查中，嗅物位似乎有利于获得更好的喉部视野。
