摘要

目的：

观察耳穴电针对脑卒中后气管切开患者气管套管拔管成功率的影响，并初探其可能的神经调控机制。

方法：

将84例脑卒中后气管切开患者随机分为观察组（42例，剔除2例、脱落2例）和对照组（42例，剔除5例）。两组均给予常规治疗。在常规治疗的基础上，对照组给予吞咽电刺激治疗，每次20 min；在对照组治疗基础上，观察组予耳穴电针治疗，取耳穴肺、咽喉治疗，采用断续波，频率5 Hz，电流1 mA，留针20 min。两组均每日治疗1次，连续治疗6 d后休息1 d，共治疗4周。比较两组患者气管套管拔管成功率和拔管时间。观察两组患者治疗前后非自主咳嗽峰流速（ICPF）、咳嗽反射分级量表（TCRGS）评分、咽运送时间（PTT）、Rosenbek渗漏-误吸量表（PAS）评分，并评定安全性。

结果：

观察组气管套管拔管成功率为89.5%（34/38），高于对照组的59.5%（22/37，

0.01）；观察组拔管时间短于对照组（

0.001）。治疗后，两组患者ICPF较治疗前升高（

0.01），且观察组高于对照组（

0.01）；两组患者TCRGS、PAS评分均较治疗前降低（

0.01，

0.05），且观察组低于对照组（

0.01，

0.05）；两组患者PTT较治疗前缩短（

0.01），且观察组短于对照组（

0.01）。两组患者均未出现明显不良反应。

结论：

耳穴电针能提高脑卒中后气管切开患者的气管套管拔管成功率，缩短拔管时间，可能与激活耳迷走神经，增强咳嗽反射、改善吞咽功能有关。

Abstract

Objective

To observe the effect of auricular electroacupuncture on the success rate of tracheal extubation in patients undergoing tracheotomy after stroke

and to explore its potential neuromodulatory mechanism.

Methods

A total of 84 patients with post-stroke tracheotomy were randomly divided into an observation group (42 cases

2 cases were eliminated and 2 cases dropped out) and a control group (42 cases

5 cases were eliminated). The routine treatment was administered in both groups. Additionally

swallowing electrical stimulation was operated

20 min each session in the control group. In the observation group

the auricular electroacupuncture was supplemented at Fei (lung

) and Yanhou (pharynx larynx

)

with intermittent wave

a frequency of 5 Hz and a current of 1 mA

and with needles retained for 20 min in each session. The treatment was administered once daily

and the duration of treatment was composed of 4 weeks at the interval of 1 day after 6 consecutive days of intervention in the two groups. The extubation success rate and extubation time of tracheotomy tube were compared between the two groups. Before and after treatment

the involuntary cough peak flow (ICPF)

the score of tracheal cough reflex grading scale (TCRGS)

pharyngeal transit time (PTT) and the score of Rosenbek penetration-aspiration scale (PAS) were observed

and the intervention safety was evaluated in the two groups.

Results

The extubation success rate of tracheotomy tube was 89.5% (34/38) in the observation group

higher than that in the control group (59.5% [22/37

]

0.01); the extubation time of tracheotomy tube in the

observation group was shorter than that in the control group (

0.001). After treatment

ICPF in both groups increased in comparison with that before treatment (

0.01)

and ICPF in the observation group was higher when compared with the control group (

0.01). The scores of TCRGS and PAS in both groups decreased in comparison with those before treatment (

0.01

0.05)

and the scores in the observation group were lower than those in the control group (

0.01

0.05). PTT in both groups was shortened in comparison with that before treatment (

0.01)

and PTT in the observation group was shorter than that in the control group (

0.01). No obvious adverse reactions were reported in either group.

Conclusion

Auricular electroacupuncture can increase the extubation success rate of tracheotomy tube and shorten the extubation time in patients with post-stroke tracheotomy

which may be associated with activating the auricular vagus nerve

enhancing the cough reflex and improving swallowing function.
