Recovery begins in a few seconds, the patient sighing or gasping, or, it
may be, vomiting; the strength of the pulse gradually increases, and
consciousness slowly returns. In some cases, however, syncope is fatal.
_Treatment._--The head should at once be lowered--in imitation of
nature's method--to encourage the flow of blood to the brain, the
patient, if necessary, being held up by the heels. All tight clothing,
especially round the neck or chest, must be loosened. The heart may be
stimulated reflexly by dashing cold water over the face or chest, or by
rubbing the face vigorously with a rough towel. The application of
volatile substances, such as ammonia or smelling-salts, to the nose; the
administration by the mouth of sal-volatile, whisky or brandy, and the
intra-muscular injection of ether, are the most speedily efficacious
remedies. In severe cases the application of hot cloths over the heart,
or of the faradic current over the line of the phrenic nerve, just above
the clavicle, may be called for.
