Hand sweat, foot sweat mostly belongs to limited hyperhidrosis, treatment is as follows: 1, local medication: can use astringent anti-sweat drugs for treatment, common such as external rubbing dilute formaldehyde solution, dilute alum solution, etc., can also use aluminum acetate, lead acetate solution, urotropine solution, etc. soak hands, feet, usually can inhibit local sweat gland secretion, so that sweating reduced; 2, physical therapy: such as the use of tap water DC ion introduction method can inhibit local sweat secretion reduction, stubborn hand sweat, foot sweat can be considered shallow X ray irradiation method, pay attention to the protection of radiation side effects; 3, injection method botulinum toxin: injection of botulinum toxin can block the local sympathetic nerve for sweat gland excitation, reduce hand sweat, foot sweat, but 0.5-1 years later need to repeat the injection; 4, surgical treatment: fluorescence development ETS minimally invasive technology is The current advanced technology in the clinical treatment of hand sweating, and is also a research hotspot in many surgical fields in recent years. This technique is fluorescence staining by non-radioactive, non-toxic fluorescent contrast agent, which can quickly, accurately and clearly observe the direction and distribution of the thoracic sympathetic ganglion covering the wall pleura and connective tissue with its variant nerve, facilitating the differentiation of other normal tissue structures around it, avoiding the presence of omissions in the treatment, thus achieving safer, finer and more complete regulation of the treatment, avoiding This allows for safer, more delicate and complete treatment, avoiding damage to other nerves and normal tissues, providing more accurate treatment results and greatly reducing postoperative complications of hand sweating, thus benefiting more patients with hand sweating.
