Supportive therapy is given if necessary, including respiratory assistance and maintenance of body temperature. Once a person has had a normal ECG for more than 24 hours they are generally medically clear. Decontamination
Initial treatment of an acute overdose includes gastric decontamination. This is achieved by giving activated charcoal, which adsorbs the drug in the gastrointestinal tract either by mouth or via a nasogastric tube. Activated charcoal is most useful if given within 1 to 2 hours of ingestion. Other decontamination methods such as stomach pumps, ipecac induced emesis, or whole bowel irrigation are generally not recommended in TCA poisoning. Stomach pumps may be considered within an hour of ingestion but evidence to support the practice is poor. Medication
Administration of intravenous sodium bicarbonate as an antidote has been shown to be an effective treatment for resolving the metabolic acidosis and cardiovascular complications of TCA poisoning. If sodium bicarbonate therapy fails to improve cardiac symptoms, conventional antidysrhythmic drugs or magnesium can be used to reverse any cardiac abnormalities. However, no benefit has been shown from Class 1 antiarrhythmic drugs; it appears they worsen the sodium channel blockade, slow conduction velocity, and depress contractility and should be avoided in TCA poisoning.
Superficial lymphatic malformation  is a congenital malformation of the superficial lymphatics, presenting as groups of deep-seated, vesicle-like papules resembling frog spawn, at birth or shortly thereafter. Lymphangioma circumscriptum is the most common congenital lymphatic malformation. It is a benign condition and treatment is not required if the person who has it does not have symptoms from it. Signs and symptoms
Lymphangioma circumscriptum is characterized by a rash on the skin featuring clear vesicles. The rash may be painful and is sometimes itchy. The vesicles often leak lymph and may bleed. The rash may appear similar to warts if the vesicles frequently break open. Diagnosis
A biopsy of the affected skin and histological examination under the microscope is necessary to diagnose lymphangioma circumscriptum. Differential diagnosis
Several other conditions may mimic lymphangioma circumscriptum. These conditions include infections such as an outbreak of herpes simplex, herpes simplex vegetans, molluscum contagiosum, verruca vulgaris, and condyloma acuminatum. Similarly, benign and cancerous non-infectious conditions may also present in a similar manner and include conditions such as angiokeratoma, dermatitis herpetiformis, hemangioma, epidermal nevus, lymphangiectasia, melanoma, angiosarcoma, and metastatic carcinomas. Treatment
The condition is benign and does not require treatment if the affected person does not have symptoms. Lymphangioma circumscriptum is often treated when it causes troubling symptoms to the affected person (itching, pain) or due to concerns about its cosmetic appearance. Surgical removal (excision) of the affected layers of skin is the most common and effective treatment.
