牙垫长度对减轻清醒气管插管患者口咽不适的影响

The effect of the length of the dental pad on relieving oropharyngeal discomfort of clear - headed patients with intubation

目的探讨牙垫长度对减轻清醒插管患者口咽不适的影响。方法选择2010年1至12月入住我院EICU20例清醒插管1d的患者使用4cm牙垫作为试验组，选择同期人住我院ICU24例清醒插管1d的患者使用6cm牙垫为对照组。比较ld内4个时段患者因牙垫造成的不适次数。结果试验组6例（30％）发生不适，对照组15例（62．5％）发生不适，差异有统计学意义（χ^2=20．4，P〈0．05）。结论使用4cm牙垫固定气管导管，对患者口咽部刺激小，可减轻患者口咽不适感，能增强清醒患者对气管插管的耐受性。

Objective To investigate the influence of the length of the dental pad on reducing oropharyngeal discomfort of clear - headed patients with intubation. Methods Totaled of 20 clear - headed patients with intubation one day in our ICU in the year of 2010 were divided into experimental group, who used 4cm dental pad, and other 24 patients were divided into control group who used 6cm dental pad. The times of discomfort due to dental pad were compared at four periods of time in one day. Results It showed that six cases （30%） appeared uncomfortable symptoms in experiment group, and 15 cases （62. 5% ） in control group. The difference was significant （χ^2 = 20, P 〈 0. 05）. Conclusions Using the 4cm dental pad to fix endotracheal tube can alleviate discomfort of patients with oropharyngeal, enhance thetolerance of awake patients with tracheal intubation.
