As the knowledge of securing patency of the air-passages by artificial respiration is generally diffused among medical students and is taught in some schools, it would be superfluous to repeat in detail the procedures of Hall, Sylvester, and others.
Laborde’s method of resuscitating those apparently dead has lately gained some notoriety. It consists in stimulating the respiratory reflex by regular rhythmical traction of the tongue, which should be vigorously pulled forward fifteen or eighteen times a minute, to correspond in frequency to the normal respiration.
Another method, alleged to have marvellous effects over the respiration, is that of anal dilatation. Its advocates claim that irritation of the anus is a much more effective measure in resuscitating the drowning or narcotized.[940]
Respiration may be further promoted by alternate dashes of hot and cold water on the face and chest, by smelling-salts, tickling the throat and nares with a feather, and by electrization of the diaphragm and inspiratory muscles. Protracted galvanism may, however, prove dangerous.
When signs of life appear, a warm tonic stimulating drink should be given. A hypodermic injection of caffeine is also recommended.
Whatever means are employed should be used on the spot in the open air and without a moment’s delay.
Restorative efforts may be kept up for two or three hours, although in the majority of cases life is extinct in the human subject after two minutes’ submersion or even less, and the chance of restoration after five minutes’ complete submersion is doubtful. To be sure, trained tank performers remain under water longer than two minutes, and exceptional instances occur of recovery after twenty minutes’ submersion in individuals in a state of syncope or with catalepsy.
CADAVERIC SIGNS IN CASES OF DROWNING.
The signs alleged to be common to death by drowning and characteristic of it are difficult to deal with, for the reason that there are no sure signs of drowning and the lesions furnished by necropsy are of feeble importance. There is consequently a divergence of opinion on this subject.
