The main manifestation of primary hand sweating is excessive sweating on the palms of both hands independent of external temperature. The sweating is usually accompanied by cold palms, and only in a few cases are the fingers kept warm during sweating. Some patients also have sweating on the feet or sweating on the head, face, or armpits. Sweating is highly correlated with emotional activity, and sweating is more frequent when the mind is under stress. The onset of symptoms is sudden and intermittent, with each episode lasting 5 to 30 minutes and the number of episodes per day varying, but sweating is rare during sleep. Most patients have more severe symptoms in summer and less severe symptoms in winter. In some patients, the sweating of the hands is immediately associated with the thought of sweating, and is much less associated with ambient temperature than with mental activity. What are the results of hand sweating surgery Thoracoscopic sympathetic surgery is currently the only treatment for hand sweating that has good lasting results. The overall effectiveness rate for excessive hand sweating is over 95%. What is the safety of hand sweating surgery? Safety is fundamental to the existence of any treatment. The sympathetic nerves are located deep inside the thoracic cavity, on both sides of the spine, so the surgery needs to be done under general anesthesia to be safest. During the surgery, instruments and endoscopes are used to enter the chest cavity, push open the lung tissue and cut the sympathetic nerve. So strictly speaking there is some danger. Especially when there are adhesions between the lung tissue and the chest wall, it may damage the lung tissue and cause complications such as pneumothorax and hemothorax. There are also other dangers such as anesthesia complications, cardiovascular complications, and intercostal vascular bleeding. However, overall, it is a minimally invasive surgery with relatively high safety. As long as the operation is standardized, the probability of the above-mentioned dangerous conditions and complications is still very low. What are the side effects of hand sweating surgery The sympathetic nerve is an important structure in the body with complex functions, and surgery to sever this tissue is bound to have some side effects. But what exactly are they and are they serious? are of great concern to sufferers. So far, the main side effects that have been observed are compensatory excessive sweating of the trunk, and individual patients will have excessively dry palms. Some patients may have some postoperative pain in the chest and back and a little numbness near the incision, but all recover gradually. The most important factor influencing the appearance and severity of side effects is the degree of sympathetic interference with the surgery. Previous surgical methods such as T2 dissection, why compensatory sweating is so powerful, is because it is extensive and heavy degree of desympathetic (sympathetic nerves are sent from a section of the spinal cord gradually up to the neck and upper limbs, the higher the cut means more nerve conduction does not go up). Later, it was improved to T3 and then to T4, which can achieve the desympatheticization of the palm and ensure the efficacy, while basically not affecting other parts and organs, and the problem of compensatory hyperhidrosis was significantly reduced, and even disappeared to a large extent. Therefore, it is a more ideal procedure. There are two cases, one is that some patients have sudden sweating of the hands about 1 week after surgery, which disappears on its own after a few days or is significantly reduced, this is called “postoperative transient sweating”, which is a temporary phenomenon, and will be relieved after a period of time. There is another situation, that is, after the surgery hand sweat is less than before surgery, but still will produce some, as long as it is not heavy, normal work life does not affect much, you can ignore it. You don’t have to worry about it getting heavier and heavier and going back to the way it was before surgery, that’s unlikely. We have noticed that some patients have been dry hands after surgery, suddenly a little sweating, nervous, thought it would be a relapse, thought it would get heavier and heavier, but after a few months found that there is no trend of aggravation, out of a little, nothing affects, so it is also frank. Of course, there are a very small number of patients who have a recurrence of hand sweating after surgery, a few months or years later. If it does come back, and the symptoms are serious and affect normal life and work, it can be treated by means of surgery again.
