PROGNOSIS.--The large majority of cases of spasm of the larynx recover. Statistics show that there are deaths from this disease, but in proportion to {73} the number attacked I think the mortality is small; how small we do not know. The confusion in classification is so great that we cannot place much dependence upon published statistics. In our climate I think most observers will admit that a patient seldom dies from this affection unless there be associated with it some morbid condition of a serious nature. TREATMENT.--The immediate and pressing indication in spasm of the larynx is for something to relax the constrictors and allow the act of inspiration to be accomplished without embarrassment. For the accomplishment of this purpose three methods of treatment may be resorted to: First, heat; second, emetics if there be time; third, anæsthetics and antispasmodics. Of all these measures, the first is the most easily applied, and will probably in a great majority of cases prove efficient. It is usually within the reach of the attendant or nurse. It can in any event do no harm. This fact is not to be overlooked, as the symptoms are so alarming that friends and physicians are often tempted to do too much. Heat may be applied by means of cloths dipped in hot water (110° F., or even more) applied to the neck and chest of the patient, or the child may be placed in a bath of 105° F., while the head is kept cool by cloths wet with cold water. This treatment may be continued till the spasms yield. The second of the measures suggested is usually safe, and may be resorted to along with the first. Those agents should be selected which act with most promptness, and the doses should be adapted to the age and condition of the patient. Alum, sulphate of zinc, sulphate of copper, are perhaps the best, but by no means the only ones. Ipecacuanha, by the relaxing effect which it has upon the muscular and nervous system, may be useful not only in overcoming the spasm, but in preventing the recurrence of the attack. Antimony is unsafe, and the other emetics are quite as useful in relaxing the muscles. The third of the measures suggested should be used with great caution. It may be doubtful whether, in fact, anæsthesia is ever indicated in simple spasm of the muscles of the larynx. The dyspnoea renders it very difficult to produce full anæsthesia, and without this the relaxing effect is not reached. In cases in which there is serious disease outside of the larynx there should be appropriate treatment directed to the extrinsic trouble. During the intermission--that is, during the day following the spasm--attention should be directed to the condition of the digestive and excreting organs as well as to the respiratory tract. In malarial districts I have thought that quinia given in antiperiodic doses the morning after the seizure has been of benefit in preventing or diminishing the severity of the next spasm. In addition to these
