作者采用表面电极代替旧法的针刺电极作喉肌电图检查。环甲肌用一般EEG电极放置颈前距中线1cm的该肌外皮上,其他喉内肌用特制电极(两片金属片嵌于一片1×1.5cm长方形硅橡胶板上,联结电极的电线在15、16、17cm处作标记)在X线指导下患者局麻将电极沿咽后壁滑下,屏气时肌电活动增加表明已达杓间肌,再下行至杓间肌下1.5 cm处即达环杓后肌,再吞咽下电极后向上牵引感有阻力时即为环咽肌。查18名正常成人和2个小儿(全麻),见平静呼吸时杓间肌无相位活动,用力呼气时活动增加,屏气时则明显增高,用力发音时也增加。环杓后肌在持续活跃状态,吸气时尤其在吸气开始时最
The authors used the surface electrode instead of the old method of acupuncture electrodes for laryngeal electromyography. Cricothyroid muscle with general EEG electrode placed 1cm away from the midline of the front of the muscle on the muscle, the other special use of the throat muscle electrode (two pieces of metal embedded in a piece of 1 × 1.5cm rectangular silicone rubber plate, the electrode wire in 15 , 16,17 cm at the mark) under the guidance of the patient under the direction of the X-ray masturbation electrodes along the posterior pharyngeal wall slide down, hold myopia when the increase in myoelectric activity showed that the intercostobal muscle, and then down to the intercostal muscle 1.5 cm up to the ring After the scaphic muscle, and then swallowing the electrode pull up the sense of resistance when the cricoid pharyngeal muscle. Check 18 normal adults and 2 children (general anesthesia), see the no-phase activity of the intercostal muscle calm breathing, forced expiratory increased activity, breath-hold was significantly higher, harder pronunciation also increased. The ring after the crab in the sustained active state, inhalation, especially at the beginning of inhalation
