. Diseases of the dog and their treatment. Dogs. 134 DISEASES OF THE BESPIBATOBY OBOANS. Diuretics and cardiac stimulants have only an indirect influence on the accumulations, and when the exudate is gradually absorbed we can hardly credit these drugs with accomplishing the results, as the exudate is usually re-absorbed when the acute inflammatory stage of the diseases has passed. The best method of treatment is the removal of the secretion by surgical means—that is, to punc- ture the chest-wall. This operation is not at all dangerous in the dog, and is generally successful unless the adhesions are too thick. The operation must be performed where there is a very large exudate and the dull sound can be heard over the entire lung; where there is oedema of the lung; in intense dyspnoea caused by the pressure of the exudate; and where there is deficient reab- sorption, as is seen when the fever has entirely disappeared and the fluid does not show any signs of becoming reabsorbed. Puncture of the cavity of the chest: The trocar used in this operation is an ordinary sized trocar, seen in Fig. 38, or, if we wish to make first an exploring puncture, we use the needle of the ordinary hypodermatic syringe. The needle, after having been disinfected, is introduced into the lower third of the wall of the chest, between the fifth and ninth rib, the patient being in a stand- ing position. The entrance of air into the thoracic cavity must be avoided, and to prevent this we must use a trocar that has a faucet, or else when the flow of fluid becomes stopped at any time from some obstruction at the end of the trocar it is well to put the finger over the end of the opening to prevent the air from being sucked into the cavity. It is well to empty the cavity slowly and never entirely, as the affected pleurae come in contact with each other and rub, often causing acute hemorrhage. After withdrawing the trocar it is well to paint the opening with some iodoform collodion. Fig. Trocar
