Acupuncture is a relatively safe and effective treatment method. However, if you do not master the operation technique of needling; or due to the patient’s inappropriate body position, mental tension and other reasons; or because of the poor quality of the needle, without inspection, etc., often lead to some abnormalities. 1, stagnant needles Phenomenon: the needle in the acupuncture point for twisting, lifting and inserting or out of the needle feel very astringent and difficult. Causes: needles when the force is too violent; twisting, lifting and inserting when the finger force is not uniform, or continuous twisting in one direction, resulting in muscle fibers wrapped around the needle body; or because of the patient’s mental tension and muscle spasms due to pain; or because the needle body into the tendon and needles twisting angle is too large, etc. can cause stagnant needle and make the needle difficult. Treatment: stagnant needles caused by body position movement, must correct the body position; such as due to patient mental tension, or local muscle spasm caused by stagnant needles, can extend the needle long stay needle time, to relieve tension; or finger in the adjacent parts of the rubbing, or in the nearby parts of the additional stabbing a needle, in order to spread the qi and blood, to relieve the spasm; such as those caused by one-way twisting, must be back to the opposite direction, and left and right light twisting to relax. Prevention: for the first time patients and nervous people, first make a good explanation, eliminate the patient’s tension and concerns. Needle must avoid the tendon; twisting angle should not be too large and too fast when the needle is in motion. More can not twist the needle continuously in one direction. 2, bent needle phenomenon: the needle body bent, the needle handle changed the direction and angle of the needle into the needle, lifting and inserting, twisting and out of the needle are difficult, the patient feels pain. Cause: the doctor into the needle technique is not skilled, too hard or needle under the encounter with hard tissue; or because of the needle when the patient’s body position mobile; also because the needle handle by the pressure of foreign objects and collision; some due to stagnant needle after the failure to timely treatment. Treatment: If the needle body is slightly bent, not to carry out the twist, the needle should be slowly withdrawn, such as the needle body bending angle is too large, you must lightly shake the needle body, in the direction of bending the needle out; if the needle body bending more than one, depending on the direction of the needle handle twist tilt, gradually withdraw in sections, do not rush to draw jerk, to prevent broken needles; such as due to changes in patient position, the patient should be asked to restore the original position, so that the local muscles relax, and then withdraw the needle. Then withdraw the needle. Prevention: the doctor should be skilled in the technique, finger force to be light, the patient should take a comfortable position, do not change position during the needle; where the needling site and the needle handle can not be subject to foreign collision or pressure; such as stagnant needle phenomenon should be dealt with in a timely manner. 3, broken needles Phenomenon: the needle body was found broken after the needle, or part of the needle body is still exposed outside the skin, or the needle body is not all into the skin below. Reason: poor needle quality, needle body or needle root has been damaged stripping, loss of inspection before the needles; doctor needles, violent lifting plug twist, resulting in severe muscle contracture; or because the patient position change, foreign object pressure collision needle body and needle handle; or because of stagnant needle, bending needle phenomenon is not timely treatment, or in the use of electric needles suddenly increase the intensity and other reasons to break the needle. Treatment: after the discovery of broken needles, the doctor’s attitude must be calm, ask the patient to maintain the original position, do not panic and do not move, to prevent broken needles to muscle deep into. If the broken needle body is still partly exposed outside the epidermis, use the right hand to hold the broken end of the forceps to take out; such as broken needle stump has been completely into the muscle layer, depending on the location of the broken needle, such as broken in the vicinity of important organs, or limb activities to prevent movement, should be located under the X-ray, immediately perform surgical removal, if in less important parts, the length of the broken needle is very short, and does not affect the daily activities, can not be dealt with. But must be regular follow-up inspection and observation, if necessary, then for treatment. Prevention: carefully and carefully check the needles, the needles that do not meet the quality requirements should be removed from use. When selecting needles, the length of the needle body should be 1 cm longer than the depth of the intended piercing. needle piercing, do not pierce the entire body of the needle, should be left part of the body outside. In the process of needle, such as the occurrence of bending needles, should immediately withdraw the needle, do not forcibly pierce. For stagnant needles and bent needles, should be properly handled in a timely manner, do not force pull hard to pull. Electro-needle apparatus in the use of check, and pay attention to the output strength knob should first be placed in the 0 position, and not suddenly increase the strength. 4, dizziness needle phenomenon: patients in the process of needling, suddenly appear pale, dizzy, dizzy, panic, shortness of breath, cold sweat, chest tightness, panic, mental fatigue, pulse sinking; serious cases will occur in the limbs cold, dazed, bowel incontinence. Causes: The patient is weak, excessive nervousness; or when tired, big Han out, hunger, diarrhea, bleeding; or due to the discomfort of the body position and the doctor in the needling technique is too heavy. Treatment: immediately stop needling, and the needles have been stabbed all out, so that the patient lie flat head position slightly lower, loosen the belt, pay attention to keep warm. Mild cases lie still for a few moments, give warm water or hot tea, you can recover. In heavy cases, on the basis of the above treatment, acupuncture points such as Renzhong, Neiguan, Yongquan, and Feosanli, and warm moxibustion points such as Baihui, Qihai and Guangyuan can be used to revive the patient, and other first aid measures should be taken if necessary. Prevention: first of all, attention should be paid to the patient’s physique, mental state, and tolerance to acupuncture reactions; for the first time to receive acupuncture treatment and nervous people, should first do a good job of explaining the work to eliminate concerns; try to take a recumbent position, and correctly choose a comfortable and lasting position; not too many points should be taken, and the technique should not be too heavy; for hungry, overworked patients, should wait until they eat, recover their strength, and then perform acupuncture. Doctors in the treatment, should always observe the patient’s expression changes, once the appearance of pale, dull, chest tightness, panic, such as dizziness needle aura, should take early measures. 5, hematoma Phenomenon: after the needle, local bruising or swelling pain. Cause: Needle stabbing injury to small blood vessels, especially when the needle tip is bent with hook. Treatment: a small amount of blood leakage or needle hole local small bruises, generally do not need to deal with, can be self-receding. If the local bruising and swelling is more painful or activity inconvenience, first cold compress to stop the bleeding, and then hot compress, or in the local gently pressed, in order to promote local bruising dissipation. Prevention: carefully check the needle, familiar with the anatomical parts, try to avoid piercing the blood vessels. Needling techniques should be gentle. The eye area acupuncture points must pay more attention. 6, after-effects phenomenon: after the needle, local discomfort such as soreness, swelling, numbness. Reason: Most of them are due to excessive manipulation; there are also due to the retention of needles for too long. Treatment: light with fingers in the local up and down patrol press, can disappear or improve; heavy in addition to the local up and down patrol press, and available moxibustion, can also be quickly eliminated. Prevention: acupuncture technique should not be too heavy; retention time should not be too long. In general, after the needle is released, see the up and down patrol press, to avoid the after-effects. 7, stabbing organs (1) traumatic pneumothorax: the back of the chest and the clavicle near the needles too deep, will stab the lungs, so that the air into the pleural cavity, the occurrence of traumatic pneumothorax. At this time, the patient suddenly feels chest pain, chest tightness, panic, poor breathing, and in severe cases, there are respiratory distress, rapid heartbeat, cyanosis, sweating, deficiency, drop in blood pressure and other shock phenomena. On physical examination, patients show excessive reverberation on percussion, and alveolar breath sounds are significantly reduced or disappeared; in severe cases, the trachea may be found to be displaced to the healthy side. X-ray chest radiography can further confirm the diagnosis and observe the amount of air leaked and the compression of lung tissue. In some cases, there is no obvious abnormality at the time of acupuncture, and only after a few hours, chest pain, dyspnea and other symptoms gradually appear, which should be noted. To prevent the occurrence of pneumothorax, needling must be concentrated, choose the appropriate body position, according to the patient’s body shape fat and thin, mastering the depth of the needle into the insertion technique should not be too large, thoracic back acupuncture points can be used oblique stab, horizontal stab, should not be left for a long time needle. Generally a small amount of gas can be self-absorption, such as coughing should be symptomatic treatment. But must be closely observed. If respiratory distress, cyanosis, shock and other phenomena are found, immediate resuscitation should be performed, such as thoracic puncture for decompression, oxygen infusion, anti-shock, etc. (2) Stabbing the heart, liver, spleen, kidney and other internal organs: Needling too deeply in the corresponding parts of the heart, liver, spleen, kidney and other internal organs can also cause serious consequences. Particular attention should be paid to patients with enlarged heart or enlarged liver and spleen. If bleeding is caused by stabbing the liver and spleen, the patient may have pain in the liver or spleen area, sometimes spreading to the back; if the bleeding does not stop and the peritoneum is stimulated, it may be accompanied by abdominal pain, abdominal muscle tension, abdominal pressure pain and rebound pain and other symptoms. When the kidney is stabbed, there is lumbago, pressure pain and percussion pain in the kidney area, and hematuria appears; when bleeding is serious and blood pressure drops to shock and other systemic symptoms occur. Injury to the viscera, light bed rest, generally can be self-healing, if there are suspicious signs of bleeding, then we should strengthen the observation, pay attention to the condition and changes in blood pressure, add hemostatic drugs or local cold compresses to stop bleeding. In case of serious injury and the appearance of shock, emergency treatment must be given quickly. Other organs, such as the gallbladder, bladder, intestines and stomach in certain pathological conditions, such as enlarged gallbladder, urinary retention, intestinal adhesions, also have the possibility of stabbing injuries, should be noted. Stabbing large blood vessels can cause hemorrhage, and attention must be paid to prevent this. (3) Stabbing injury to the cerebral spinal cord: If the angle, direction and depth are not appropriate, the brain can be accidentally injured, causing serious consequences. Acupuncture points in the midline of the back between the spinous processes above the first lumbar vertebrae are too deep and can pierce the spinal cord, resulting in electric shock-like sensations radiating to the extremities, and sequelae can occur with excessive stimulation. When acupuncture points in these areas, it is necessary to hold a high degree of responsibility, always pay attention to the acupuncture induction, and do not mention the plug pounding. If the stimulation is too strong, the patient will experience transient limb paralysis, and if the stabbing vascular, it can cause bleeding or hematoma compression symptoms. Mild cases to strengthen observation, quiet rest, gradually recover, such as acupuncture found after the headache, nausea, vomiting and other phenomena, or even a coma, should be promptly rescued. (4) stabbing nerve trunk: needles in the nerve trunk and nerve root acupuncture points, after the emergence of electric shock-like radiation sensation, such as repeated needling, there is a risk of damage to nerve tissue. Due to the different degrees of nerve injury and can cause sensory or motor dysfunction of the damaged nerve, some cases may also appear burning pain and reflex muscle spasms or contractures and other phenomena.
