1. Dizziness or even vomiting when riding in the car. In life, some people often feel dizzy, upset in the upper abdomen, cold sweat and even vomiting soon after getting on the bus. Especially when the car brakes suddenly, turns sharply or starts suddenly, it can be gradually relieved or recovered after getting off for a period of time. Some people's carsickness symptoms can last for several days. What's going on here? The human body can judge the direction and maintain its own balance, mainly relying on the superficial skin receptors, the deep receptors of the eyes, neck and body, and the inner ear, of which the inner ear is the most important. The semicircular canal, elliptical sac and balloon of the inner ear mainly play a balancing role. There are three semicircular canals, which are perpendicular to each other and form three sides of the space. They receive external balance stimulation, pass through vestibular nerve, reach the balance center of cerebral cortex, and regulate and manage the balance response. Why do you get carsick? 1, individual differences. When the incoming balance stimulus is too strong, such as sudden braking and violent rotation, even when the balance system is safe and normal, people will feel dizzy, which is a normal physiological phenomenon and will disappear in a short time. However, some people have poor tolerance and react strongly to slight balanced stimuli. 2, poor sleep, overwork is easy to happen. It is easy to happen when you are hungry and full. 4, can occur when suffering from certain ear diseases. The carriage is sealed, the air is not circulating, or the smell of some substances is irritating, such as gasoline. How to prevent carsickness? 1. People who often get carsick can take Haloning before taking the bus, 25 mg for adults each time, with fewer children to prevent carsick reaction. 2. Eat before the car is full or hungry. 3. You should not be overworked before riding, and sleep well the night before. 4. You can sit in the front of the car to reduce bumps, open the window to make it well ventilated, then tilt your head back in a fixed position and close your eyes to reduce dizziness caused by head vibration and flying eyes. 5. When vomiting, you can take Yunning or metoclopramide. You can take sedatives when you are nervous, such as valium. 6, usually should strengthen exercise, enhance physical fitness, especially in anti-dizziness, such as doing more turning, spinning in place, rolling and other sports, through which motion sickness can be alleviated. 1. Why do you get seasick, carsick and airsick? Motion sickness, also known as motion sickness, is a general term for motion sickness, seasickness and airsickness. It refers to cold sweat, nausea, vomiting, dizziness and other symptoms caused by excessive exercise stimulation of vestibular balance receptors in human inner ear and excessive bioelectricity of vestibular organs when riding vehicles. The vestibular organ of the inner ear is the balanced sensory organ of the human body, including three pairs of semicircular canals and the oval sac and balloon of the vestibule. There is ampulla crest in semicircular canal and otolith (also called cyst spot) in the balloon of elliptic capsule, which is the vestibular terminal receptor and can feel the stimulation of various specific motion States. The semicircular canal feels angular acceleration (deceleration) movement stimulation, while the balloon of elliptical capsule and balloon feels horizontal or vertical linear acceleration (deceleration) change. When the vehicle we ride rotates or turns (for example, the car turns and the plane moves in a circle), the angular acceleration acts on the corresponding semicircular canals on both sides of the inner ear. When the hair cells in the ampulla of a semicircular canal are stimulated to bend and deform to produce positive potential, the opposite hair cells bend and deform to produce negative potential (negative voltage), and the exciting or inhibiting electrical signals of these nerve endings are transmitted to the vestibular center through nerves and perceive this movement state; Similarly, when the vehicle has linear acceleration (deceleration) changes, such as car starting, acceleration and deceleration braking, ship shaking and bumping, elevator and airplane lifting, etc., these stimuli cause deformation and discharge of hair follicle hair cells in vestibular elliptic sac and balloon, which are transmitted to the center and are perceived. The generation and transmission of these vestibular electrical signals will not cause adverse reactions within a certain limit and time, but everyone's tolerance for the intensity and time of these stimuli is limited, and this limit is the vertigo threshold. If the stimulus exceeds this limit, there will be motion sickness symptoms. Everyone's tolerance varies greatly, which is not only related to genetic factors, but also influenced by vision, individual physique, mental state and objective environment (such as air smell). Therefore, under the same objective conditions, only some people have motion sickness symptoms. 2. How to prevent and treat carsickness (seasickness, carsickness, airsickness)? Accurately speaking, carsickness is not a real disease, which is different from the usual diseases. It's just an emergency response of sensitive organisms to over-limit stimuli. Therefore, there is no real radical cure or cure, and the existing prevention and treatment methods are to temporarily relieve symptoms or delay their occurrence. The best way to prevent and treat motion sickness is to avoid or leave the environment that can cause motion sickness, but this is unrealistic. In the past, many drugs were used to prevent and treat motion sickness, mainly sedative and emetic drugs, such as Cheng Yunning, scopolamine, diazepam, etc., to inhibit central excitement and relieve gastrointestinal spasm. However, these drugs have many side effects, slow action, dry mouth and drowsiness, and the curative effect is not ideal. There is a skin patch behind the front ear, which is a slow-release scopolamine. It can be absorbed through the skin, but it still cannot eliminate the inherent side effects of the drug. Other methods, such as sticking navel, pressing Neiguan point, opening window for ventilation and looking forward, are also commonly used, and the effect is extremely limited. There is also vestibular exercise, which, like pilot training, repeatedly stimulates the vestibule for a long time, such as swivel chair, swing, crouching tiger, rowing and so on. To make the vestibule adapt to the habit can achieve the purpose of relieving motion sickness symptoms. But if you stop training or leave the exciting environment, the symptoms of motion sickness will reappear. In the past, vestibular balance medical experts from all over the world have been committed to the prevention and treatment of motion sickness for a long time, but with little effect, there has been no breakthrough. Now, Professor Hu Guang Ai, director of the Otolaryngology Research Institute of Tianjin No.1 Central Hospital and director of the Vertigo Diagnosis and Rehabilitation Center, and the chief physician, after more than ten years of clinical research, have invented an electronic anti-motion sickness instrument according to the principles of vestibular balance medicine and classical vestibular clinical theory. The instrument generates pulsed electrical signals through electronic oscillation, and then acts on the vestibule, the balance organ of human inner ear, through binaural electrodes, so as to counteract or weaken the excessive bioelectricity generated by excessive movement-linear and angular acceleration (deceleration) stimulation, reduce and prevent vestibular nerve impulses from transmitting to the center, thus improving the tolerance of vestibular organs to various sports stimuli and achieving the purpose of treating motion sickness. This is a brand-new and pioneering treatment for carsickness. In the process of use, users can always keep a clear head, change the state of irritability, thirst and drowsiness when taking sedatives in the past, and make today's journey chic and brisk, so that they can enjoy the beautiful scenery of the motherland and the happiness of modern civilization. The research project was rated as "the first in the world" by experts, and won the Tianjin Science and Technology Progress Award, the National Invention Expo Silver Award and the national patent (98 3 26062.438+0) successively, and was listed as a scientific and technological innovation promotion product in Tianjin. This product (No.:22603 1, No.98, Jin (Zhun)) was put on the market and was immediately praised by the majority of carsickness patients. 3. Why do carsick people drive or not? Because carsickness is mainly caused by excessive stimulation of human vestibular nervous system, the excitability of vestibular nervous system is the key. The vestibular nervous system belongs to the low-level center, which is influenced by the high-level center of cerebral cortex, and the high-level center has inhibitory effect on the low-level center. People with carsickness are in a highly concentrated state when driving, and the high excitement of the advanced cerebral cortex inhibits the vestibular system, so naturally they will not get carsick. But when riding as a passenger, there is no such effect. Similarly, when the battle alarm sounded, sailors who were originally seasick were immediately able to fight high. 4. Why do some people get carsick, but they don't get carsick after fainting? Good vestibular function of inner ear is one of the basic conditions for motion sickness (seasickness, carsickness, airsickness). If the vestibular function is lost, the human body will lose the ability to accept all kinds of acceleration (deceleration) sports stimuli, that is, all kinds of bad or over-limit stimuli that cause motion sickness will lose their effect on the human body. Therefore, some people with bilateral vestibular dysfunction (ototoxic drug poisoning, bilateral labyrinthine resection, repeated vertigo attacks, etc. ) After getting dizzy, you won't get carsick. 5. Why do carsick people get carsick more easily with the more advanced means of transportation? Although the vestibule of the inner ear has a good function and can accept all kinds of acceleration (deceleration) stimuli, which is one of the basic conditions for motion sickness (seasickness, carsickness and airsickness), a certain range of acceleration (deceleration) stimuli are suitable for motion sickness, but those high-frequency bumps (produced by ordinary vehicles) are not suitable, but the surging acceleration and shaking produced by vehicles with good balance are most suitable for vestibule. Therefore, the more advanced the vehicle, the easier it is to get carsick. 6. Will the smell of gasoline make you carsick? Motion sickness is caused by excessive stimulation of the vestibule of the inner ear. The smell of gasoline may aggravate the nausea of some carsickness patients, but it is not the cause of carsickness. Imagine staying at home and smelling gasoline will make you carsick? As for some people who are allergic to gasoline, that is another matter. Edit this paragraph | Go back to all kinds of carsickness prevention methods 1. Take 1 to 2 capsules with warm boiled water 40 minutes before taking the bus or boat, and reduce the amount for children. 2, cold. In the absence of dizziness, you can use Ganmaotong instead, the method is the same as above, and the effect is the same. 3. Diazepam 1 tablet and vitamin B 1 tablet can also be taken with warm water 40 minutes before boarding the bus, which can also prevent carsickness. 4. Take 65,438+0 slices of fresh ginger or 65,438+0 slices of fresh potato and stick it on Shenxiejue (navel) and cover it with Shangshi ointment. At the same time, paste Shangshi Zhitong ointment on Neiguan point and gently rub the point with your fingers. You can also put a piece of fresh ginger in your mouth, which also has a certain preventive effect. 5. Metoclopramide: Metoclopramide 1 tablet, 2 tablets can be taken in case of serious carsickness, and children should reduce the amount as appropriate, and swallow it 10 ~ 15 minutes before getting on the bus to prevent carsickness. If you travel for more than 2 hours and have motion sickness symptoms, you can take 1 tablet again. Those who take medicine temporarily on the way should stand 15 ~ 20 minutes after taking medicine and sit down to take medicine. The effective rate of this method is 97%, and there are no side effects such as dry mouth and dizziness caused by other motion sickness drugs. 6. Orange peel: Before getting on the bus 1 hour or so, fold the surface of fresh orange peel outward and inward, and then squeeze it at two nostrils, and the fragrant oil mist will be sprayed from the skin. Inhale 10 times or more, and inhale at any time on the way. 7. Fengyoujing: Apply Fengyoujing to temples or Fengchi points during the ride. You can also drop two drops of essential balm on your navel, and cover it with Shangshi Zhitong ointment. 8. Vinegar: Drink a cup of warm boiled water with vinegar before taking the bus, so it is not easy to get carsick on the way. 9. Shangshi Zhitong Ointment: Take Shangshi Zhitong Ointment and stick it on the navel before taking the bus to prevent carsickness. 10, Pinch Neiguan point with your fingers: When you are carsick, you can pinch Neiguan point with your thumb (Neiguan point is on the palm of your wrist, about two fingers on the wrist transverse stripes, between the two tendons). 1 1, when there is no medicine, people with carsickness can tighten their belts before getting on the bus to prevent their internal organs from shaking too much. Try to look at distant objects with your eyes as little as possible after getting on the bus, especially when going downhill, pay attention to pressing your hands to slow down the impact of inertia on internal organs, and pay attention to ventilation in a tightly sealed car or a car with heavy gasoline smell, which will help prevent carsickness, such as a slight feeling. Those who have a history of carsickness can drink some hot and sour appetizers before taking the bus, and don't eat sweets and greasy food to avoid being too hungry and full. Zhan Peiyuan, an attending physician in Guangdong Department of Neurology, said that motion sickness and seasickness are very common phenomena, with organic reasons, functional and psychological reasons. Among children, the incidence rate of boys is higher than that of girls, while the incidence rate of adults is higher. Usually we are used to walking on the ground, but we are not used to unfamiliar sports stimuli, such as bumping up and down and vacillating when riding a car, taking a boat or flying. Some healthy people have no organic diseases and dysfunction, but after being stimulated by strenuous exercise in different directions and at different speeds, they may have symptoms such as motion sickness, seasickness and airsickness, such as dizziness, pallor, nausea and vomiting. This is a very normal physiological reaction. As long as people get rid of the stimulating environment, the symptoms will disappear naturally. The symptoms of motion sickness often develop gradually, from stomach discomfort to nausea, cold sweat and finally vomiting. Motion sickness can be prevented. Although everyone's physique and sensitivity are different, and some people are particularly sensitive, there are still ways to help these people who are prone to carsickness avoid carsickness. (1) Strengthen physical exercise and enhance the tolerance of vestibular organs. Motion sickness mostly occurs in people with sensitive vestibular organs. Therefore, pay more attention to exercise, turn around, bend over and squat to increase the tolerance of vestibular organs. (2) Overeating, fatigue, lack of sleep, dirty air, emotional stress and special smells such as gasoline and lampblack may all contribute to the occurrence and aggravation of carsickness, and these unfavorable factors should be avoided. (3) Specialized vestibular training. Motion sickness can be prevented by rehabilitation training, such as repeated boat and car training, to improve the adaptability of vestibular organs to irregular movements. In addition, people who are afraid of carsickness can often participate in some activities, especially those that help to adjust the balance of human body position, such as swinging, sliding, parallel bars, rolling on the mat, etc., which can improve the adaptability of vestibular organs. (4) When riding or taking a boat, try to limit the head movement, and rest your head on the back of the chair to reduce acceleration stimulation, especially rotation stimulation. If possible, try to lie flat. (5) Avoid bad visual stimuli. Look out of the window less when riding, and it is easier to induce motion sickness by reading by car or boat, so closing your eyes can reduce the occurrence of motion sickness. You can eat some yihanning buccal tablets before taking the bus to prevent carsickness. Anticholinergic drugs can inhibit cerebral cortex and prevent dizziness and vomiting. Exercise cures motion sickness and seasickness. Most people are well adapted to traveling by boat. But for some carsick people, this is an arduous task. Every time these people travel by boat, they are dizzy, disgusting, bored and uncomfortable. At the worst, they are dizzy, upset and miserable. Motion sickness is a general term for motion sickness, seasickness, airsickness and other diseases caused by factors such as shaking, bumping, rotating and accelerating exercise. People who are prone to carsickness have poor adaptability to irregular posture changes such as rotation, which is the balance organ of the inner ear. Of course, there are other inducing factors of carsickness, such as high temperature, high humidity, poor ventilation, noise, bad smell, emotional tension, lack of sleep, excessive fatigue, hunger or satiety, physical weakness and so on. Medical experts point out that motion sickness can be treated by exercise. Usually, patients can consciously do some swinging and rotating movements, such as bending over, shaking their heads, standing step by step repeatedly, and do some large-scale rotating movements after getting used to it, such as slowly rotating the body left and right alternately with the help of a swivel chair. Through gradual exercise, the adaptability of vestibular organs of the inner ear to irregular movements can be enhanced, and motion sickness can be gradually alleviated or even overcome. Experience: change direction! For example: Generally, the car we take is facing the front of the car. When you start to feel uncomfortable, you can turn your body 90 degrees to the left or right! Of course, it is best to turn around in advance, not necessarily 90 degrees, so standard! ) from the experience, you can try it without spending a penny! Also, most of the dashboards of many private cars now have different perfumes. My children never get carsick, and taxis often leave. How can they faint once after buying a car at home? Then find out the reason by yourself, pour out the perfume to smell, and then install tap water. My child won't get carsick after riding a bike. Parents in similar situations can try it. Don't part with your perfume. Perfume holder can also be used as decoration. The best treatment for carsickness and seasickness is 1. Take it easy. Keep relaxed and don't always think about dizziness. You'd better find someone to talk to and relax. You should have enough sleep before traveling. Adequate sleep will make you feel better and improve your ability to resist sports stimuli. 3. It is not advisable to be too hungry or too full by means of transportation. Eating can only be seven or eight points full, especially high-protein and high-fat foods, otherwise it is prone to nausea and vomiting. 4. Try to sit in a seat that is relatively stable and consistent with the direction of movement. Keep the air circulating. 5, the head is properly fixed to avoid excessive swing. 6. Take motion sickness medicine orally half an hour before taking the bus. 7. Try not to look at the fast-moving scenery outside the window. You'd better close your eyes. If a sandman invades you, congratulations! In addition, some people tried to stick a traumatic pain-relieving ointment on the navel, which had a certain effect, but the mechanism remains to be discussed. 8. Take motion sickness medicine. For example, Halo Haining, taken half an hour before the bus ride, is suitable for adults or children over 6 years old. Metoclopramide tablets should be taken 15 ~ 30 minutes before the bus ride or half an hour before the meal. General carsickness patients take 5mg (1 tablet), and severe patients take 10mg (2 tablets). 9. Fresh ginger. Hold fresh ginger slices in your hand and smell them at any time while driving, so that the spicy taste can be inhaled into your nose. You can also stick a piece of ginger on your navel and fix it with Shangshi Zhitong ointment. 10, fresh orange peel. Before getting on the bus 1 hour or so, aim the fresh orange peel at the two nostrils and squeeze, and inhale the fragrant oil mist. 1 1, essential oil. Rub the essential balm on the temples, or drop two drops of essential balm on the navel, and cover it with the ointment for relieving dampness and pain. 12, vinegar. Drink a cup of warm water with vinegar before taking the bus. 13, Zhitong ointment. Before taking the bus, take the ointment for treating dampness and relieving pain and stick it on your navel. People who often get carsick and try to swing mainly rely on the vestibular function of the inner ear in addition to the proprioception of vision and joint muscles, and can perceive the position and movement changes of the head, trunk and limbs. Vestibular organs can be roughly divided into semicircular canals and otoliths, which have extremely sensitive sensory devices. The semicircular canal feels the stimulation of the change of head rotation movement through the flow of endolymphatic; Otolith feels the stimulation of body tilt and linear motion through the gravity of otolith. The central nervous system regulates the tension of muscles in various parts of the body and maintains the normal posture of the body. For people with vestibular dysfunction or excessive sensitivity, sudden changes in head position and movement speed can cause dizziness, nausea and vomiting, thus affecting the balance of the body. However, when specific stimuli repeatedly act on vestibular organs, after a period of time, vestibular response will gradually weaken, and the stability of vestibular function will be strengthened through active training. This phenomenon is called vestibular acclimatization. This is why figure skaters and dancers can spin freely and quickly. Swing is the simplest and cheapest training method to enhance the stability of vestibular function, establish habits and improve the balance ability of human body. The fitness mechanism of traditional sports, which has lasted for more than 2500 years, has been gradually revealed by modern science. When swinging, people swing back and forth with the swing board, and the direction and speed of movement, potential energy and kinetic energy, and the height from the ground are constantly changing. The body is in a rapid change between overweight and weightlessness, and the air pressure in the ear cavity fluctuates. In this way, vestibular sensory cells will be stimulated by the constant change of endolymphatic flow and otolith gravity, and the nerve impulse generated by the change of membrane potential will relieve vestibular organs alternately from acute to chronic. This can improve the adaptability and stability of sensory cells. This is the basic mechanism of swinging to exercise vestibular balance acclimatization. People who often swing rarely get carsick. The higher the swing, the longer the time, and the better the acclimatization effect. The fitness effect of swinging is systemic. While constantly overcoming tension and fear, it can enhance psychological endurance and self-control; When the limbs and head are limited, skeletal muscle contracts and relaxes rhythmically, which is also beneficial to the increase of muscle fiber volume. There is no cure for carsickness. Motion sickness refers to cold sweat, nausea, vomiting, dizziness and other symptoms when riding a car, and its specific mechanism is not completely clear. According to an old Chinese doctor, carsickness is related to people's physique. At present, there is no long-term treatment for carsickness, but there are many short-term treatments for carsickness, including drugs and some folk remedies. Edit this paragraph | What should I do to get carsick? 1. In the nystagmus test, the patient was asked to sit on the bed, lie flat on his back, with his head down 10 second, observe 10 second without dizziness and eye trauma, sit up and observe 10 second, then lie flat on his back, with his head facing to one side 10 second, and then lie flat on his back. For example, the right ear is down, nystagmus rotates to the right, eyes stare to the left, and vertical nystagmus appears, which is called non-fatigue type after repeated tests. On the contrary, repeated tests no longer appear nystagmus, which is called fatigue type. The direction of nystagmus in different head positions is unchanged, which is called directional type; If nystagmus appears in different directions, it is called change direction type. Nystagmus appears in one-way head position with short duration and short incubation period. Most patients with directional fatigue reaction are peripheral lesions. On the contrary, most of them are central lesions. Other tests, such as visual tracking and visual movement, are normal. 2. The vestibular function such as cold and hot temperature changes is normal. 3. How normal the pure tone listening test is. (1) Conservative treatment of this disease has a good prognosis and can heal itself in about one year. Individual patients who have not recovered for a long time can take symptomatic treatment, such as oral diazepam and commonly used vitamins. You can also use forced posture to exercise, and use the characteristics of fatigue reaction to fix it in the posture induced every day for long-term exercise, so that you can adapt for a long time and won't feel dizzy. If dizziness is serious, 4% lidocaine and streptomycin sulfate can be injected into the tympanum, which can achieve good results. (2) Surgical treatment is ineffective for long-term conservative treatment, and vestibular neurotomy can be used. If conditions permit, it is best to perform posterior ampullary neurotomy, as long as the abnormal impulse of ampullary crest of posterior semicircular canal is eliminated, it can be cured. Using the stapes incision in the ear, the tympanic membrane flap was turned forward to expose the ankle joint and the round window, and the bottom of the round window was polished horizontally to 1 ~ 2mm with a diamond drill. In order to facilitate the operation, the posterior inferior bone wall of the external auditory canal can be ground off a little with a drill, so that the round window can be clearly exposed. The posterior ampullary nerve is located within 65438±0mm of the inner edge of the circular window membrane. After identifying the nerve under the microscope, hook it up, cut it off, restore it to the tympanic membrane, and fill the external auditory canal% d% a.
