A text-book of the diseases of the ear for students and practitioners . arying prolonged reflex hawking, the emphysema increases during the firstfew hours ; it is therefore important to instruct the patient to suppress asmuch as possible the act of swallowing or of clearing the throat for somehours. If the emphysema increases to such an extent as to produce difficultyin respiration, a means of escape for the air can be made by incising themucous membrane of the pharynx with a sharp bistoury or by cutting the30ft palate with a pah of scissors (Guy). In emphysema of the cheeks andneck, repeated friction of these parts has been recommended, but, in the authorsopinion, it does not seem to be a good method of treatment, because the airis driven towards the pharynx and the disorder thereby increased. As a rule,the emphysema disappears in a few days without treatment.* From the foregoing it is evident that in all cases in which amarked resistance is encountered on compression of the air-bagthe instrument must be somewhat withdrawn. By this action,. ?* —m Fig. 77.—Air-douche with the India-rubber Air-Bag. the orifice of the catheter, which has become occluded bypressure against the posterior wall of the tube, is rendered free,and the air can enter the canal unchecked. In order to avoidsuch incidents, caused by improper fixation of the instrument, itis advisable, with each compression, to press the catheter slightlytowards the balloon with the thumb and index finger of the lefthand; the object of moving the catheter towards the bag isto counteract the pressure exerted on the catheter during com-pression. The impact of the bag against the catheter is over-come by applying a short piece of rubber tubing to the nozzle ofthe air-bag and connecting it with the free end of the catheter. The most powerful action of the bag is obtained when, as in Fig. 77, itis held with the thumb and palm of the hand and compressed on its side withthe four fingers. On tbe other h
