2.5. Intervention method

We will require patients to stay in bed absolutely and give them oxygen to keep their airways open. Patients with severe breathing disorders may undergo tracheotomy. Patients with indications for brain surgery will be treated with surgery. Our goal is to prevent and treat cerebral edema, gastrointestinal bleeding and other complications. In addition, we will also carry out routine neurosurgical treatment and nursing care for patients, such as infection control, supplementation of energy polarizing fluid and nutritional supply. When the patient's vital signs and condition are stable, they will be given acupuncture to promote awakening and assist in treatment.

The control group will be given conventional comprehensive treatment of western medicine, dehydration, hemostasis, and nourishment of brain cells (intravenous infusion of monosialic acid ganglioglyceride 80 mg, 1 time/d, after 2 weeks of continuous use, change to 40 mg, 1 time/d, then use 4 to 6 weeks; intravenous infusion of calf serum 1.6 g, once a day, for 2 weeks), surgical treatment will be performed in time when there are surgical indications. At the same time, we will pay close attention to changes in blood sugar, electrolytes and liver and kidney function to prevent and treat complications such as gastrointestinal bleeding.

The treatment group will be given acupuncture treatment on the basis of the control group. We will select the following acupoints as the main acupuncture sites: Baihui, Sishenchong, Neiguan, Sanyinjiao, Xuehai, Fengchi, Quchi, Shuigou. Baihui is located at the intersection of the middle line of the head and the tip of the ears. It is closely connected with the brain and is the key point for regulating brain function. Baihui is the place where all meridians converge. Being able to reach the yin and yang veins and connect the meridians throughout the body plays an important role in regulating the balance of yin and yang in the body. Sishenchong is located 1 inch apart from the front, back, left, and right sides of Baihui on the top of the head, with a total of 4 acupuncture points. There are branches of the greater occipital nerve, ear cervical nerve and supraorbital nerve around this point. This acupuncture point mainly treats madness, epilepsy, stroke, hemiplegia, forgetfulness, insomnia, headache, dizziness, cerebral hypoplasia, hydrocephalus, head pain, and so on. Pierce 0.5–0.8 inches horizontally. The Neiguan is located 2 inches above the transverse crease of the forearm, between the palmar longus tendon and the flexor carpi radialis tendon. This point is commonly used in modern times to treat angina, myocarditis, arrhythmia, gastritis, hysteria, and so on. Pierce the skin 0.5 to 1 inch vertically. Sanyinjiao is an acupuncture point of the body. Sanyinjiao refers to the intersection of qi and blood in the 3 meridians with yin attributes on the feet. Xuehai is on the inner thigh, 2 inches above the medial end of the patellar base, and is located on the bulge of the medial head of the quadriceps when the knee is bent. Fengchi is located on the back of the neck, under the back of the skull, in the lacuna on the outer edge of the two large tendons, equivalent to the level of the earlobe. Fengchi is in the depression between the attachment between the sternocleidomastoid muscle and the upper end of the trapezius muscle. The deep layer is the splinter muscle; there are branches of occipital arteries and veins; and the minor occipital nerves are distributed. Quchi is located at the lateral end of the elbow transverse striae, at the midpoint of the line between Chize and the lateral epicondyle of the humerus when the elbow is bent. This acupuncture point has the functions of clearing away heat and removing the surface, dredging the channels and collaterals. Shuigou is on the face, at the intersection of the upper 1/3 and the middle 1/3 of the middle groove. The acupoints are distributed with the infraorbital nerve branch and the buccal branch of the facial nerve. This acupoint is mainly used for coma, syncope, heatstroke, madness, epilepsy and other diseases. Needle insertion method: puncture 0.3 to 0.5 inch diagonally upward.
