Controversy persists as to whether the lung interposes on the needle electrode insertion path during diaphragm electromyography (EMG).
Using high-resolution ultrasonography, we measured the distances between the medial recess of the intercostal spaces (ICSs) around the mid-clavicular line (MCL) and the lung margin. We performed measurements bilaterally during quiet breathing in the seated and supine positions.
We studied 10 young healthy men and found that, in the first ICS with the medial recess clearly (i.e., several cm) lateral to MCL (usually the eighth ICS), the distance between the recommended insertion site and the lung margin varied from 7.5 to 17 cm. The distance was slightly larger on the right side and in the supine position.
This study confirms that properly conducted "trans-intercostal" needle EMG of the diaphragm is generally safe in healthy subjects. Muscle Nerve 54: 54-57, 2016.
在膈肌肌电图（EMG）检查过程中，肺部是否会处于针电极插入路径上一直存在争议。
我们使用高分辨率超声测量了锁骨中线（MCL）周围肋间间隙（ICSs）内侧隐窝与肺边缘之间的距离。我们在坐位和仰卧位安静呼吸时双侧进行测量。
我们研究了10名年轻健康男性，发现，在第一个内侧隐窝明显（即距离MCL数厘米）位于MCL外侧的肋间间隙（通常是第八肋间间隙），推荐的插入部位与肺边缘之间的距离在7.5至17厘米之间。右侧和仰卧位时该距离略大。
本研究证实，在健康受试者中，正确进行的膈肌“经肋间”针电极肌电图检查通常是安全的。《肌肉与神经》54: 54 - 57, 2016年。
