Bed rest until the temperature returns to normal. Diet - table No. 13, in severe cases - enteral-parenteral nutrition. Treatment of anthrax includes etiotropic and pathogenetic therapy, carried out depending on the form of the disease and the existing clinical and laboratory syndromes. Etiotropic treatment of anthrax is presented in the treatment regimens for different forms of the disease.

Etiotropic treatment of anthrax should be combined with a single administration of specific anti-anthrax immunoglobulin at a dose of 20-100 ml intramuscularly (the dose depends on the severity of the condition). Local therapy consists only of treating the affected areas of the skin with antiseptic solutions. Bandages are not applied. Surgical intervention is contraindicated, since it contributes to the generalization of the infection. In the development of infectious toxic shock, widespread edema of the face and neck, it is recommended to administer prednisolone at a dose of 90-240 mg. Detoxification therapy is carried out according to individual indications. In the generalized form of the disease, antibiotic therapy is combined with intensive detoxification, measures aimed at combating hemodynamic disorders. Intravenous perfusions of polyionic solutions are used in the volume necessary to restore the volume of circulating blood, microcirculation, water-electrolyte balance (2-5 l), daily with the addition of 100 ml of polyglucin, rheopolyglucin or hemodez. Oxygen therapy, hyperbaric oxygenation, and extracorporeal detoxification methods are used.
Approximate periods of incapacity for work
Discharge of recovering patients with cutaneous anthrax is carried out after the rejection of the scab and the formation of a scar. Patients who have suffered from generalized forms of the disease are discharged after complete clinical recovery and two negative results of bacteriological studies, carried out at intervals of 5 days. Dispensarization is not regulated.
