In the German Hospital system the patient, male or female, is given a quarter of a grain of morphine sulphate hypodermatically half an hour before narcosis. The anesthesia is always induced with anaesthol or chloroform. _Where much blood is lost or the operation is of very long duration one may at any time make the transition to ether by the drop method without changing the mask._ As a rule, a morphine-anaesthol narcosis is given with a few drops of ether now and then (ether feeding), when a little stimulation is indicated. In a small number of cases, among them choledochotomies and other operations on the gall-bladder, particularly where there is jaundice, the morphine-anaesthol introduction is followed by the ether drop method. CARDIAC COLLAPSE. Cardiac collapse is fortunately uncommon. It usually occurs during the induction of anesthesia. Suddenly there is a marked pallor of the face and the pulse becomes weak. It happens in chloroform, and occasionally in anaesthol narcosis. When such a tendency is discovered _ether_ should be given by the drop method. _Gradual induction_ of anesthesia until the patient’s tolerance to chloroform is ascertained, is of cardinal importance. RESPIRATORY COLLAPSE. Obstructed breathing developing during the induction of narcosis is apt to be due to _crowding_. If obstructed breathing becomes manifest later, that is, during the course of the operation, it may be due to _inhibitory reflex elicited by the surgeon_. Traction on the gall bladder or mesentery will sometimes evoke a peculiar noisy breathing which does _not_ mean that the patient is insufficiently under the influence of the anesthetic. The breathing becomes normal and unrestrained as soon as the surgeon desists from these vigorous manipulations. [Sidenote: Crowding] [Sidenote: Respiratory Collapse]
