Abstract

Background. Endotracheal intubation frequently causes laryngeal injury, including edema, ulceration, and vocal cord immobility. These problems can complicate the immediate postextubation course. Methods. The authors measured the cuff leak and made bedside assessment of the voice in 51 patients requiring mechanical ventilation for acute respiratory failure. Results. The median tidal volume was 450 mL (range = 300-600 mL). The median duration of ventilation was 3 days (range = 0-19 days). The median cuff leak was 180 mL (range = −33 to 460 mL); the median percentage cuff leak was 40.9% (range = −7.75% to 99.2%). Women had significantly smaller cuff leaks (18.6% of tidal volume vs 50.3% in men, P = .01). Patients with hoarseness frequently had smaller cuff leaks (median 24.1% vs. 46.7% in nonhoarse patients). Eleven patients (84.6%, 11/13) with a cuff leak 15% had hoarseness (P = .01). Four patients had stridor, and all had a cuff leak >15% of the ti...

拔管时袖带泄漏测试与语音质量评估相关

背景。气管内插管经常引起喉损伤，包括水肿、溃疡和声带不动。这些问题会使拔管后的治疗过程复杂化。方法。作者对51例急性呼吸衰竭需要机械通气的患者进行了袖带泄漏测量和床边声音评估。结果。中位潮气量450 mL(范围300-600 mL)。通气时间中位数为3天(范围0-19天)。中位袖带漏180 mL(范围= - 33 ~ 460 mL);袖带泄漏的中位数百分比为40.9%(范围= - 7.75%至99.2%)。女性袖口渗漏明显较小(潮气量的18.6% vs男性的50.3%，P = 0.01)。声音嘶哑的患者通常有较小的袖带泄漏(中位数为24.1%，而非声音嘶哑的患者为46.7%)。11例(84.6%，11/13)患者有袖带渗漏，其中15%的患者声音嘶哑(P = 0.01)。4例患者有喘鸣，所有患者均有袖带漏，占总病例的15%。
