1. Dizziness or even vomiting when riding in a car. In life, some people often feel dizzy not long after getting in a car, with upper abdominal discomfort, nausea, cold sweats, and even vomiting. This is especially worse when the car brakes suddenly, makes a sharp turn, or starts suddenly. After getting off the car, resting for a while can gradually alleviate the symptoms. or restore. For some people, symptoms of motion sickness can last for several days. What's going on? The human body's ability to judge direction and maintain its own balance is mainly responsible for the superficial receptors in the skin, the deep receptors in the eyes, neck and body, and the inner ear, of which the inner ear is the most important. The semicircular canals of the inner ear as well as the utricle and saccule have primarily a balancing function. There are three semicircular canals, which are perpendicular to each other and form three sides of space. They receive external balance stimulation and transmit it to the balance center of the cerebral cortex through the vestibular nerve to regulate and manage the balance response. Why do you get motion sickness? 1. Individual differences. When the incoming balance stimulation is too strong, such as sudden braking or violent rotation, people will feel dizzy even when the balance system is safe and normal. This is a normal physiological phenomenon and will disappear in a moment. However, some people have poor tolerance and have strong reactions to slight balance stimulation. 2. It is easy to occur when you have poor sleep and are overworked. 3. It is also easy to occur when you are too hungry or full. 4. It may occur when suffering from certain ear diseases. 5. The compartment is sealed so that the air does not circulate, or the smell of certain substances, such as gasoline, is irritating. How to prevent and treat motion sickness? 1. People who often suffer from motion sickness can take Chengchenin before riding in the car, 25 mg per time for adults and less for children to prevent motion sickness. 2. Don’t eat too full or too hungry before taking the bus. 3. You should not be overtired before taking the bus, and sleep well the night before. 4. You can sit in the front of the car to reduce bumps, open the windows to allow good ventilation, and lean your head back on a fixed position with your eyes closed to reduce dizziness caused by head vibration and eyes flying. 5. When vomiting, you can take Chengyuning or metoclopramide. When you are nervous, you can take sedatives, such as diazepam. 6. Exercise should be strengthened in daily life to enhance physical fitness, especially in the fight against dizziness, such as doing more exercises such as turning the head, rotating in place, rolling, etc., through these exercises, motion sickness can be alleviated. 1. Why do we get seasick, carsick and airsick? Motion sickness, also known as motion sickness, is a general term for motion sickness, seasickness, airsickness, etc. It refers to a group of symptoms such as cold sweats, nausea, vomiting, dizziness and other symptoms that occur when the vestibular balance receptors in the human inner ear are stimulated by excessive movement when riding in vehicles, and the vestibular organs produce excessive bioelectricity, which affects the nerve center. The vestibular organ of the inner ear is the body's balance receptor, which includes three pairs of semicircular canals and the utricle and saccule of the vestibule. There is an ampullae ridge in the semicircular canals and an otolith organ (also called a macule) in the utricle saccule. They are vestibular terminal receptors that can sense the stimulation of various specific motion states. The semicircular canals sense angular acceleration (deceleration) velocity motion stimulation, while the utricle and saccule vesicles sense changes in horizontal or vertical linear acceleration (deceleration) velocity. When the vehicle we ride rotates or turns (such as a car turning or an airplane moving in a circular motion), angular acceleration acts on the corresponding semicircular canals of the inner ear on both sides. When the hair cells in the ampulla of the semicircular canal on one side are stimulated to bend and deform, a positive potential is generated at the same time. , the hair cells on the contralateral side bend and deform to generate opposite potentials (negative electricity). The excitatory or inhibitory electrical signals of these nerve endings are transmitted to the vestibular center through the nerves and sense the motion state; similarly, when the riding vehicle undergoes linear acceleration (deceleration) speed changes , such as when a car starts, accelerates and decelerates, brakes, ships shake, bump, elevators and planes rise and fall, these stimuli cause the follicular hair cells of the vestibular utricle and saccule to produce deformation discharges, which are transmitted to and sensed by the central nervous system. People will not have adverse reactions to the generation and transmission of these vestibular electrical signals within a certain limit and time, but everyone has a limit to the intensity and time of these stimulations. This limit is the stun threshold. If the stimulation exceeds At this limit, symptoms of motion sickness will appear. Everyone's tolerance varies greatly. In addition to genetic factors, this is also affected by factors such as vision, individual physique, mental state, and objective environment (such as air odor). Therefore, under the same objective conditions, only some people have different tolerances. Symptoms of motion sickness occur. 2. How to prevent and treat motion sickness (seasickness, motion sickness, airsickness)? To be precise, motion sickness is not a real disease. It is different from diseases in the usual sense. It is just an emergency response of a sensitive body to excessive stimulation. Therefore, there is no real cure or cure, and all existing prevention and treatment methods temporarily relieve symptoms or delay its occurrence.
The best way to prevent and treat motion sickness is to avoid or leave the environment that can cause the disease, but this is very unrealistic. In the past, drugs were mostly used to prevent and treat motion sickness, mainly sedative and antiemetic drugs, such as Chengyuning, scopolamine, diazepam, etc., which inhibit central nervous system excitement and relieve digestive tract spasm. However, most of these drugs have side effects such as slow action, dry mouth, drowsiness, etc., and their efficacy is not ideal. There used to be a behind-the-ear skin patch on the market, which was a scopolamine sustained-release agent that could be penetrated and absorbed through the skin, but it still could not eliminate the inherent side effects of the drug. Other methods such as sticking the navel, pressing the Neiguan point, opening windows for ventilation and looking forward are also commonly used but have extremely limited effects. There are also vestibular exercise methods, just like pilot training, which repeatedly stimulate the vestibule over a period of time, such as rotating chairs, swings, leaning on the tiger, rowing, etc., so that the vestibule can adapt to the habit, which can achieve the purpose of alleviating the symptoms of motion sickness. . But if you stop training or get out of the stimulating environment, the symptoms of motion sickness will reappear. In the past, vestibular balance medicine experts from various countries around the world have long been committed to research on the prevention and treatment of motion sickness, but with little success and no breakthrough. Now it’s better. Professor Hu Guangai, director of the Institute of Otolaryngology and Vertigo Diagnosis, Treatment and Rehabilitation Center of Tianjin First Central Hospital, and chief physician, based on the principles of vestibular balance medicine, combined with the classic vestibular clinical theory, and after more than ten years of clinical research, invented An instrument for treating motion sickness - an electronic anti-sickness device. This instrument can generate pulse electrical signals through electronic oscillation, and then act on the vestibule, the balance organ of the human inner ear, through binaural electrodes to offset or weaken the excessive bioelectricity generated by the vestibule due to excessive movement of the human body - linear and angular acceleration (deceleration) speed stimulation. , reduce and prevent the transmission of vestibular nerve impulses to the central nervous system, thereby improving the tolerance of the vestibular organ to various exercise stimuli and achieving the purpose of treating motion sickness. This is a brand-new and pioneering method of treating motion sickness. During the use, the user can always keep a clear mind, changing the state of being upset, dry mouth, and drowsy when traveling in the past by taking sedatives. Today's journey is smooth and brisk, allowing you to enjoy the beautiful landscape of the motherland and enjoy the happiness of modern civilization. This research topic has been evaluated by experts as an "international first" level. It has won the Tianjin Science and Technology Progress Award, the National Invention Expo Silver Award, a national patent (98 3 26062.1), and is listed as a Tianjin science and technology innovation and promotion product. This product (Jin Yao Qi Jian (quasi) No. 98 No. 226031) was immediately praised by the majority of patients with motion sickness as soon as it was put on the market. 3. Why can people with motion sickness drive but not ride in cars? Because motion sickness is mainly caused by excessive stimulation of the human vestibular nervous system, the level of excitability of the vestibular nervous system is key. The vestibular nervous system is a low-level center, which is affected by the high-level centers of the cerebral cortex, and the high-level centers have an inhibitory effect on the low-level centers. When a person who suffers from motion sickness is driving, he is in a state of high concentration, and the high-level centers of the cerebral cortex are highly excited and exert an inhibitory effect on the vestibular system, so he will naturally not get motion sickness. This effect does not occur when riding as a passenger. Similarly, when the battle alarm sounds, the seasick naval officers can immediately enter the battle with high morale. 4. Why do some people get motion sickness before but no longer get motion sickness after suffering from vertigo? Good vestibular function of the inner ear is one of the basic conditions for motion sickness (seasickness, motion sickness, airsickness). If the vestibular function is lost, the human body will also lose the ability to accept various acceleration (deceleration) speed motion stimuli, that is, various adverse or over-limit stimuli that cause motion sickness will lose their effect on the human body. Therefore, it turns out that people who suffer from motion sickness will Some of those with bilateral vestibular loss (ototoxic drug poisoning, bilateral labyrinthectomy, recurrent vertigo attacks, etc.) do not suffer from motion sickness. 5. Why are people who get motion sickness more likely to get motion sickness the more advanced the vehicle they ride in? Although the vestibular function of the inner ear is good and can accept various acceleration (deceleration) speed motion stimuli, which is one of the basic conditions for causing motion sickness (seasickness, motion sickness, airsickness), there are certain acceleration (deceleration) speed motion stimuli that are suitable for causing motion sickness. Within the range, those high-frequency bumps (generated by ordinary vehicles) are not suitable stimuli for it, and the surge-like acceleration shakes produced by vehicles with better stability and stability during operation are most suitable for the taste of the vestibule. Therefore, the more advanced the vehicle, the easier it is to get motion sickness. 6. Can the smell of gasoline cause motion sickness? Motion sickness is caused by excessive stimulation of the vestibule of the inner ear. The smell of gasoline may aggravate the nausea symptoms of some people with motion sickness, but it is not the cause of motion sickness. Just think about it, will you get carsick if you smell gasoline at home? As for some people being allergic to gasoline, that's another matter. Edit this paragraph | Back to the top Various ways to prevent motion sickness 1. Take advantage of motion sickness.
Take 1 to 2 tablets with warm boiled water 40 minutes before boarding a car or boat, the dosage may be reduced for children. 2. Cold. In the absence of Chenghunning, Ganmaotong can be used instead. The method is the same as above and the effect is the same. 3. You can also take one diazepam tablet and two vitamin B1 tablets with warm water 40 minutes before riding to prevent motion sickness. 4. You can take 1 piece of fresh ginger or 1 piece of fresh potato and stick it on the Shenjue point (navel), cover it with Shangshi ointment, and at the same time stick the Shangshi analgesic ointment on the Neiguan point, and gently rub the acupoint with your fingers. , you can also hold a piece of fresh ginger in your mouth, which also has a certain preventive effect. 5. Metoclopramide: 1 tablet of metoclopramide, 2 tablets can be taken when motion sickness is severe. The dose may be reduced for children. Swallow it 10 to 15 minutes before getting in the car to prevent motion sickness. If you experience motion sickness again after traveling for more than 2 hours, you can take another tablet. People who take medicine temporarily on the way should stand for 15 to 20 minutes and then sit down after taking the medicine to facilitate the absorption of the medicine. This method is 97% effective and has no side effects such as dry mouth and dizziness caused by other motion sickness films. 6. Orange peel: About an hour before riding, turn the surface of a fresh orange peel outward, fold it inward, and then squeeze it against your nostrils, and aromatic oil mist will be ejected from the peel. It can be inhaled more than 10 times. You can also inhale this method at any time while riding in the car. 7. Fengyoujing: Apply Fengyoujing to your temples or Fengchi point while riding in the car. You can also put two drops of wind oil essence on the belly button, and cover it with Shangshi pain relieving ointment. 8. Vinegar: Drink a glass of warm water with vinegar before taking a ride to prevent motion sickness during the ride. 9． Shangshi analgesic ointment: Apply Shangshi analgesic ointment to the navel before riding to have a significant effect in preventing motion sickness. 10. Pinch the Neiguan point with your fingers: When motion sickness occurs, you can use your thumb to pinch the Neiguan point (the Neiguan point is on the palm side of the wrist joint, about two fingers across the wrist crease, between the two tendons). 11. In the absence of medicine, those who suffer from motion sickness can tighten their belts before getting in the car to prevent their internal organs from shaking excessively in the body. After getting in the car, focus on the distance and try to look less at nearby objects. Especially when going downhill, be careful to hold on to your hands. , slow down the impact of inertia on internal organs. Pay attention to ventilation in tightly sealed cars or compartments with a strong gasoline smell. This will help prevent motion sickness. If you feel slightly uncomfortable, you should immediately choose a suitable seat in front of the car to sleep. Sleep - -It is often the best, most cost-effective and effective way to prevent motion sickness. If you have a history of motion sickness, you can drink some sour and spicy appetizing food before riding, avoid eating sweets and greasy foods, and avoid being overly hungry or full. A wonderful way to treat motion sickness and seasickness, according to Zhan Peiyuan, an attending physician at the Department of Neurology in Guangdong Province, said motion sickness and seasickness are very common. The phenomenon has organic reasons, as well as functional and psychological reasons. Among children, the incidence rate is higher in boys than in girls, and in adults, it is more common in women. Normally, we are accustomed to walking on the ground, and are not accustomed to relatively unfamiliar sports stimuli, such as the up and down bumps and vacillations of traveling in cars, boats, and airplanes. Some healthy people without organic diseases or functional disorders may experience motion sickness, seasickness, and airsickness such as dizziness, pale complexion, nausea and vomiting after being stimulated by the above-mentioned strong movements in different directions and speeds. This is a very normal physiological reaction, and the symptoms will disappear naturally as long as people are away from the stimulating environment. Symptoms of motion sickness often progress gradually, from stomach upset to nausea, cold sweats, and finally vomiting. Motion sickness is preventable. Although everyone's constitution and sensitivity are different, and some people are particularly sensitive, there are still ways to help those who are prone to motion sickness avoid motion sickness. (1) Strengthen physical exercise and enhance vestibular organ tolerance. Motion sickness often occurs in people with sensitive vestibular organs. Therefore, you should pay more attention to physical exercise and do more movements such as turning your head, bending and squatting, etc., to increase the tolerance of the vestibular organ. (2) Overeating, fatigue, lack of sleep, dirty air, emotional stress, and special smells such as gasoline and oil smoke may contribute to the occurrence and worsening of symptoms of motion sickness, so these adverse factors should be avoided. (3)Special vestibular training. Motion sickness can be prevented through rehabilitation training, such as repeated boating and car riding training to improve the vestibular organ's ability to adapt to irregular movements. In addition, people who are afraid of motion sickness can often participate in some activities, especially sports that help adjust the position and balance of the human body, such as swings, slides, single and parallel bars, mat tumbling and other sports, which can improve the adaptability of the vestibular organs. (4) When riding in a car or boat, head movement should be limited as much as possible. You can rest your head on a back chair and immobilize it to reduce acceleration stimulation, especially rotational stimulation. If possible, lie flat on your back. (5) Avoid bad visual stimulation. Avoid looking out the window when riding in a car. Reading while riding in a car or boat is more likely to induce motion sickness. Therefore, closing your eyes and relaxing can reduce the occurrence of motion sickness.
You can take Yihanning lozenges before riding to prevent motion sickness. Anticholinergic drugs have an inhibitory effect on the cerebral cortex and can prevent dizziness and vomiting. Exercise to cure motion sickness and seasickness. Most people can adapt well to traveling by car or boat. But for some people who suffer from motion sickness, it is a chore. Whenever these people take a car or boat, they may feel dizzy, nauseated, depressed and uncomfortable, or in severe cases, dizzy, queasy, and miserable. Motion sickness is a general term for motion sickness, seasickness, airsickness, and diseases caused by factors such as swinging, bumping, rotating, and accelerating movements. People who are prone to motion sickness have poor adaptability to irregular changes in body position such as rotation, the balance organ of the inner ear, the vestibular organ. Of course, there are other triggering factors for motion sickness, such as high temperature, high humidity, poor ventilation, noise, bad smell, emotional stress, lack of sleep, excessive fatigue, hunger or overeating, physical weakness, etc. Medical experts point out that motion sickness can be treated with exercise. Patients can usually consciously do exercises that involve swinging and rotation. For example, they can gradually do some exercises that lower their heads and bend over, shake their heads, and squat and stand up repeatedly. After they gradually adapt, they can do some exercises with larger rotations, such as Use the swivel chair to slowly rotate your body left and right alternately. Through gradual exercise, the adaptability of the vestibular organ of the inner ear to irregular movements can be enhanced, and motion sickness can be gradually reduced or even overcome. Lesson from experience: Change direction! (For example: Generally, when we sit in a car, we face 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 your body in advance, and it does not have to be 90 degrees. , such a standard!) Speaking from experience, you can try it and it doesn’t cost a penny! Also, many private cars now have different perfumes placed on the dashboard. My child has never gotten motion sick in a car, and he often rides in taxis. After buying a car for my family, why do I get sick every once in a while? Pour out the perfume, remove the fragrance, and then fill it with tap water. My child will not get motion sickness in the car in the future. Parents with similar situations can try it. Don’t be reluctant to part with your perfume. The perfume holder can also be used as a decoration. Tips for treating motion sickness: 1. Don’t be nervous. Keep your mind relaxed and don't always think about getting dizzy. It's best to find someone to chat with you to distract you. 2. You should get enough sleep before traveling. If you get enough sleep, you will be in good spirits and can improve your ability to resist exercise stimulation. 3. It is not advisable to be too hungry or too full when taking transportation. Eat only seven to eight percent full, especially high-protein and high-fat foods, otherwise nausea, vomiting and other symptoms may easily occur. 4. Try to sit on a seat that is relatively stable and consistent with the direction of travel. and maintain air circulation. 5. The head should be properly fixed to avoid excessive swinging. 6. Take oral motion sickness medicine half an hour before taking transportation. 7. Try not to look at the fast-moving scenery outside the window. It's best to close your eyes and rest your mind. If the Sandman attacks, congratulations! Another note: Some people tried applying the pain-relieving ointment on the navel and it had a certain effect, but the mechanism remains to be explored. 8. Take motion sickness medication. For example, Haining, taken half an hour before taking the bus, is suitable for adults or children over 6 years old. Metoclopramide tablets should be swallowed 15 to 30 minutes before riding or half an hour before meals. Generally, those with motion sickness should take 5 mg (1 tablet), and those with severe motion sickness should take 10 mg (2 tablets). 9. Fresh ginger. While driving, hold fresh ginger slices in your hand and smell them at any time to inhale the spicy flavor into your nose. You can also stick a ginger slice on your navel and fix it with Shangshi Pain Relief Ointment. 10. Fresh orange peel. About an hour before taking the bus, squeeze fresh orange peels against your nostrils and inhale the aromatic oil mist. 11. Fengyoujing. Apply wind oil essence to the temples, or drop two drops of wind oil essence to the navel, and cover it with Shangshi Pain Relief Ointment. 12. Vinegar. Drink a glass of warm water with vinegar before riding. 13. Pain-relieving ointment. Apply Shangshi Pain Relief Ointment to your belly button before riding. People are always motion sick and try swinging. People can sense the position and movement changes of the head, trunk, and limbs. In addition to vision and proprioception of joints and muscles, it mainly relies on the vestibular function of the inner ear. The vestibular organs can be roughly divided into semicircular canals and otolith organs, which contain extremely sensitive sensory devices. The semicircular canals sense the stimulation of changes in the rotational movement of the head through the flow of endolymph; the otolith organs sense the stimulation of changes in body tilt and linear motion through the gravity of the otolith. The central nervous system regulates the tension of muscles in various parts of the body and maintains the body's normal posture. For people with vestibular dysfunction or oversensitivity, sudden changes in head position and movement speed can cause dizziness, nausea, and vomiting, affecting the body's balance.
However, when a specific stimulus repeatedly acts on the vestibular organ, the vestibular response will gradually weaken after a period of time, and the stability of the vestibular function will be enhanced through active training. This phenomenon is called vestibular habituation. This is why figure skaters and dancers can spin quickly and freely with ease. Swinging is the simplest and cheapest training method to enhance the stability of vestibular function, establish habituation, and improve the body's balance ability. The fitness mechanism of traditional sports that have lasted for more than 2,500 years has been gradually revealed by modern science. When swinging, the person swings back and forth with the swing board. The direction and speed of the movement, the 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 suddenly increases and decreases. . In this way, vestibular receptor cells will be stimulated by the constant changes in endolymph flow and otolith gravity. The nerve impulses generated by changes in membrane potential will cause the vestibular organ to be soothed alternately between acute and chronic conditions. This improves the adaptability of the receptor cells and enhances their stability. This is the basic mechanism for exercising vestibular balance habituation by swinging. People who often swing on swings rarely suffer from motion sickness or seasickness. The higher you swing and the longer you swing, the better the acclimation effect will be. 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 restricted, skeletal muscles contract and relax rhythmically, which is also conducive to the increase in muscle fiber volume. There is no treatment for motion sickness. Motion sickness refers to a group of symptoms such as cold sweat, nausea, vomiting, and dizziness that occur when riding in a car. Its specific mechanism is not yet fully understood. According to a well-known veteran Chinese medicine doctor, motion sickness is related to people's constitution. Currently, there is no long-term treatment for motion sickness. However, there are many short-term treatments for motion sickness, including drugs and some folk remedies. Edit this paragraph | Back to the top What tests should be done for motion sickness? 1. For head position nystagmus test, ask the patient to sit on the bed, first lie on his back with his head down, observe for 10 seconds that there is no dizziness or nystagmus, then ask him to sit up and observe for another 10 seconds, and then Lie on your back with your head to one side and observe for 10 seconds. Then lie on your back with your head tilted to the other side and observe for 10 seconds. Each change of body position, sitting up and lying down should be completed within 3 seconds. If nystagmus occurs in a certain position, , should be observed continuously for 30 seconds. If the nystagmus does not disappear, the test is positive. For example, when the right ear is downward, the nystagmus rotates to the right, and when the eyes gaze to the left, vertical nystagmus occurs. If repeated tests are positive, it is called non-fatigue type; conversely, if nystagmus no longer occurs after repeated tests, it is called fatigue type. . Nystagmus that appears in different head positions is called directional type; nystagmus that appears in different directions is called changing type. If nystagmus occurs in one-way head position, lasts for a short time, has a latent period, and is directional with fatigue reaction, it is mostly a peripheral lesion; otherwise, it is mostly a central lesion. Other tests such as visual tracking and optokinesis are generally normal. 2. Vestibular function tests such as hot and cold temperature changes are normal. 3. Pure tone hearing tests are mostly normal. (1) Conservative treatment: The prognosis of this disease is good and it can heal without treatment in about a year. Individual patients who cannot recover for a long time can use symptomatic treatment, such as oral diazepam and vulgaris. You can also use forced position exercises, taking advantage of the characteristics of fatigue response, and perform long-term exercises in the induced positions every day. Over time, you can adapt and no longer feel dizzy. If the vertigo is severe, intratympanic injection of 4% lidocaine and streptomycin sulfate can achieve good results. (2) Surgical treatment: If long-term conservative treatment is ineffective, vestibular neurotomy can be used for treatment. If conditions permit, it is best to perform posterior ampulla nerve transection, which can cure the disease simply by eliminating the abnormal impulse of the ampullae ridge of the posterior semicircular canal. Use the stapes surgical incision in the ear to turn the tympanic membrane forward to expose the malleolus-anvil joint and the round window. Use a diamond drill to grind away 1 to 2 mm of the bottom of the round window horizontally. In order to facilitate the surgical operation, you can first use a drill to grind away a little of the posterior and inferior bone wall of the external auditory canal to clearly expose the round window.
The posterior ampulla nerve should be located 1mm within the inner edge of the round window membrane attachment. After identifying the nerve under the microscope, hook it up and cut it, return it to the tympanic membrane, and fill the external auditory canal%D%A You have already evaluated it! %D%AGood:0%D%AYou have already rated it! %D%ANot good:0%D%AYou have already rated it! %D%AOriginal:0%D%AYou have already rated it! %D%A Non-original: 0%D%A I love bacteria/xLx%D%A TA’s star record: %D%A 1%D%A 0%D%A 0%D%A My star page% D?010-12-09 09:30%D%A Satisfactory answer%D%A
