Sunstroke

Sunstroke (Insolatio). As a result of prolonged exposure to heat, usually from the direct rays of the sun, an attack of unconsciousness sometimes supervenes, usually attended with stertorous breathing, small frequent pulse and great heat of the surface. The attack is sometimes quite sudden, but is usually preceded by giddiness, nausea, a sense of prostration, and other premonitory symptoms. Recovery is generally slow, and a fatal issue by no means uncommon. The most effectual treatment consists in the application of cold to the head. Counter-irritants and stimulants are sometimes employed.
