Regional Anatomy:
Skin-subcutaneous tissue-trapezius muscle-rhomboid muscle-muscle-erector spinal muscle.
In the superficial layer, there are the cutaneous branches of the posterior branches of the 5th and 6th thoracic nerves and the accompanying arteries and veins, In the deep layer, there are the dorsal scapular nerve, the dorsal scapular artery and vein, the muscular branches of the posterior branches of the 5th and 6th thoracic nerves and the branches or tributaries of the dorsal branches of the related posterior intercostal arteries and veins.
Location:
Lie pronely; at the level of the lower border of spinous process of the 5th thoracic vertebra, 3 cun apart from ShendaoGV11(Shendao (GV11)) laterally.
Function:
Relieving mental stress, regulating qi and blood, removing obstruction from the channels and collaterals.
Indications:
Coronary heart disease, angina cordis, rheumatic heart disease, atrial fibrillation, tachycardia, neurasthenia, schizophrenia, bronchitis, asthma, intercostal neuralgia, rachiasmus, and pain in the shoulder and arm.
Prescription:
Combined use with ZusanliST36 (Zusanli (ST36) He-Sea Point) for treatment of angina cordis; with LiequeLU7 (Lieque (LU7)Luo-Connecting Point the Eight Confluent Point) for treatment of bronchitis; and with ZhongfuLU1 (Zhongfu (LU1)) for treatment of dysphasia.
Methods: Insert the needle horizontally, 0.5-0.8 cun deep; needling response: local numbness and distension; moxibustion: using 3-5 moxa-cones, or mild moxibustion for 10 min.
Note:
Don`t puncture deeply, or else the needle would penetrate the levator muscles of ribs-the external intercostal muscle-the internal intercostal muscle-the parietal pleura-the pleural cavity-the visceral pleura and the lung by its tip, and cause an injury to lung tissue and leading to pneumatothorax.
