The result in this case, as in many similar ones which I had occasion to observe during and after the ice-bag treatment, was that the inflammation in the lungs had been arrested and suppressed during the stage of destruction, when the air cells and tissues were filled with exudates, blood serum, pus, live and dead blood cells, bacteria, etc., leaving the affected areas of the lungs in a consolidated, liver-like condition.
Such counterirritation makes possible the absorption of the inflammatory exudates by changing the chronic inflammation to the acute form. WOUNDS. A wound, in the restricted sense that the term is commonly used, includes only such injuries that are accompanied by breaks or divisions of the skin and mucous membrane. It is usually an open, hemorrhagic injury.
They are filled with morbid exudates, pus, etc., which interfere with and make impossible normal nutrition and functioning. If suppression takes place during this stage, it is obvious that the affected areas will be left permanently in a condition of destruction. Here is an illustration from practical life: Suppose necessary changes and repairs have to be made in a house.
The character of an inflammation is largely modified by the nature of the tissue in which it occurs. A serous inflammation is characterized by serous, watery exudates. This form occurs in the serous membranes, mucous membranes and skin. Sero-fibrinous inflammations, such as occur in pleurisy and peritonitis, are common.
Taking cold may be caused by chilling of the surface of the body or part of the body. In the chilled portions of the skin the pores close, the blood recedes into the interior, and as a result of this the elimination of poisonous gases and exudates through these portions of the skin is suppressed.
The inflammatory exudates become organized at the beginning of this stage, and the air can not enter the air cells. This period lasts several days. Resolution marks the beginning of recovery or convalescence. Toward the end of the second period, the inflammatory exudate in the air cells has begun to degenerate.
We can now understand how the processes just described produce the well-known cardinal symptoms of inflammation and fever; the redness, heat and swelling due to increased blood pressure, congestion and the accumulation of exudates; the pain due to irritation and to pressure on the nerves.
In this case the point of infection was walled in, as all such cases are, with exudates and whether the appendix was primarily affected or not doesn't matter; it was within this enclosure and found to be ruptured, which is common; but its rupture was of no consequence because the escaped contents were in the abscess cavity that finally emptied into the cecum, the natural outlet in all these cases if they are left to nature and not officiously fingered thumbed and punched to death.
The diet should be varied from day to day to encourage the appetite. It has for several years been recognized that a salt-free diet in dropsies due to disease of the kidneys is a valuable aid in causing absorption of such exudates and of preventing greater exudations. For this reason a salt-free diet is often ordered in dropsies occurring in valvular disease.
In the last stage, these exudates undergo liquefaction and are absorbed, or expelled by coughing, in from seven days to two weeks, depending on the extent of the inflammation and the general condition of the animal. In the subacute form the symptoms are mild and may subside within a week. Sometimes abscesses form in the lung.
