The effectiveness of three techniques for opening an airway obstructed by the tongue was studied and compared. The research involved patients who were anesthetized for elective surgery. The first group of patients, not breathing on their own, were ventilated by mouth-to-mouth breathing. The second group was unconscious, making spontaneous respiratory effort, but had total airway obstruction produced by the tongue from relaxation of the lower jaw. The three techniques--neck lift, chin lift, and jaw thrust--were performed on all patients in both groups. The adequacy of ventilation was compared subjectively and by measuring air flow with a Wright Respirometer. Results indicate that the chin lift technique provides the most consistently adequate airway.
对三种打开因舌头阻塞气道的技术的有效性进行了研究和比较。该研究涉及接受择期手术麻醉的患者。第一组患者自主呼吸停止，通过口对口呼吸进行通气。第二组患者失去意识，有自主呼吸努力，但由于下颌松弛导致舌头完全阻塞气道。对两组所有患者均实施了三种技术——抬颈、抬颏和推下颌。通过主观评估以及使用赖特呼吸计测量气流来比较通气的充分性。结果表明，抬颏技术能最持续地提供充分气道。
