Symptoms of Hg poisoning

The diagnosis of acute mercury poisoning is based on the working history or intake history, clinical manifestation and determination of urine mercury or blood mercury (significantly increased). The diagnosis of slow mercury poisoning should focus on the history of touch. The clinical manifestations include energy nerve manifestation, stomatitis and tremor, and other similar clinical manifestations caused by other causes. The increase of urine mercury and blood mercury is helpful for the diagnosis. In mercury expelling experiment, 0.25g sodium Dimercaptopropanesulfonate could be injected intramuscularly; 5 g, intravenous injection; If urinary mercury excretion is significantly increased, it can be used as an important auxiliary basis for diagnosis.

It is mainly caused by mercury compounds such as oral mercury. Patients with acute erosive stomatitis and gastroenteritis after a few minutes to dozens of minutes. The patient complained of burning pain in the mouth and throat, nausea, vomiting, abdominal pain and diarrhea. Vomiting and feces often have bloody mucus and falling necrotic arrangement. Patients often have peripheral circulation failure and gastrointestinal perforation. Acute renal failure may occur after 3-4 days (severe within 24 hours). One can have liver damage.

It is often caused by working inhalation of mercury vapor, and a small number of patients can also be caused by the use of mercury preparations. The first manifestation of energy nerve is dizziness, headache, insomnia and dreaminess, followed by excitement or depression, anxiety and fear, as well as the manifestation of autonomic nerve dysfunction, such as blushing, sweating and skin scratch. Muscle tremor occurs first in fingers, eyelids and tongue, and then in arms, lower limbs, head and even the whole body; It is more obvious when people pay attention and are excited. Oral manifestations are mainly manifested as mucosal congestion, ulcer, gingival swelling and bleeding, tooth loosening and falling. The blue and black mercuric sulfide fine particles can be seen in the gingiva of the patients with poor oral hygiene. The mercury line placed in rows is a symbol of mercury absorption. In the aspect of kidney, the primary subclinical renal tubular function is harmful, such as low molecular weight proteinuria, nephritis and nephrotic syndrome. Renal damage is expected to recover after mercury exposure. Patients with chronic poisoning may also have weight loss, sexual dysfunction, women's menstrual disorders or abortion, hyperthyroidism and peripheral neuropathy. The brown light reflection in the anterior chamber of the ocular lens is considered to be mercury lentinitis caused by mercury calmness. After the poisoning can not be seen or separated from the touch of mercury, the brown light reflection can still exist for a long time, which is another symbol of mercury absorption.
