POULTICES (cataplasmata) — the medical procedure intended for local warming up of a body part.

Medical action of P. is connected with the weakening influence of heat on a tone of vessels of the warmed-up area (increase in a blood-groove), a tone of unstriated and skeletal muscles (a spasmolysis, reduction of rigidity) and with activation of phagocytosis in inflammatory infiltrates.

Apply the substances which are badly carrying out heat to P. Distinguish dry and wet Items. Dry P. are trained from various loose materials: sand, oats, etc. They are warmed up and filled in sacks of necessary size and a form. Such P. are convenient since they densely adjoin to the part of a body intended for warming up. Wet P. are trained from a flax seed or oats; at warming up to them add a little boiling water or hold over steam. Wet P., as well as warming compresses (see), cause more uniform and longer expansion of blood vessels, than dry poultices. Carry also hot mud and paraffin flat cakes to P. (see. Mud cure , Paraffin therapy ).

For preservation of heat of P. from above cover with an oilcloth, and then a warm blanket. Wet P.'s temperature shall be lower, than dry since the thermolysis in the wet atmosphere decreases and the burning sensation arises at lower temperature. For increase in duration of action of P. sacks with heated material change before their noticeable cooling. Sometimes P. hold for hours.

Items are shown at patol. the processes demanding local thermal influence — long forms of a local inflammation, it is long not resolving infiltrates, the organized hematomas, muscular spasms, etc.

A contraindication to P.'s use are acute purulent processes, abdominal pains of an unspecified origin, internal bleeding, an active form of tuberculosis, malignant new growths, heart and vascular failure, disturbances of sensitivity of skin, unconsciousness, i.e. the same processes and states at which are contraindicated hot-water bottle (see).
