■肺中的自主神经以及肋间和膈神经对呼吸运动很重要。这项研究调查了通过交感神经进行电针(EA)刺激对最大呼吸压力的影响。
■这个前景,单中心,随机交叉研究在TeikyoHeisei大学进行,日本。受试者为17名健康成年人(15名男性和2名女性),在为期2周的洗脱期的交叉试验中,他们被随机分配到未治疗和EA组。最初,对两组患者进行呼吸压力测试.休息5分钟后,要么休息5分钟,要么提供EA刺激,然后休息5分钟。EA在左侧第六颈椎水平的颈神经节附近递送。EA刺激设置为2Hz,并将刺激强度设置为使志愿者感觉不到疼痛的水平。在休息或EA刺激期间测量鼻部皮肤温度。此后,两组患者均再次测试呼吸压力.
■EA组在干预期间鼻-皮肤温度显著降低,在干预后吸气和呼气呼吸口腔压力显著升高,与非刺激组相比。
■通过交感神经的2-HzEA刺激激活了交感神经,并抑制了呼吸口腔压力减弱。需要进一步的研究来评估EA治疗支气管狭窄和呼吸无力的有效性。
UNASSIGNED: The autonomic nerves in the lungs and the intercostal and phrenic nerves are important for respiratory movements. This
study investigated the effects of electroacupuncture (EA) stimulation via the sympathetic nerve on maximal respiratory mouth pressure.
UNASSIGNED: This prospective, single-center, randomized crossover
study was conducted in Teikyo Heisei University, Japan. The subjects were 17 healthy adults (15 men and 2 women), who were randomly assigned to untreated and EA groups in a crossover
trial with a 2-week washout period. Initially, respiratory mouth pressure was tested in both groups. After 5 minutes of rest, either a 5-minute rest or an EA stimulus was delivered, followed by 5 minutes of rest. EA was delivered near the cervical ganglia at the level of the sixth cervical vertebra on the left side. The EA stimulus was set to 2 Hz, and the stimulation intensity was set to a level so that no pain would be felt by the volunteers. Nasal-skin temperature was measured during rest or EA stimulation. Thereafter, respiratory mouth pressure was tested again in both groups.
UNASSIGNED: The EA group had a significant reductions in nasal-skin temperature during the intervention and a significant increase in inspiratory and expiratory respiratory mouth pressure after the intervention, compared to the nonstimulated group.
UNASSIGNED: The 2-Hz EA stimulation via the sympathetic nerve activated the sympathetic nerves and suppressed respiratory mouth pressure weakness. Future studies are needed to evaluate EA\'s effectiveness for treating bronchial stenosis and respiratory weakness.
