The plentiful use of cold water will generally be sufficient to stop the bleeding, though cases are on record in which the use of styptics, or even the temporary closure of a bleeding point by pressure, has been necessary.
M. Guersant has operated on more than one thousand children, with only three cases of any trouble from hæmorrhage, while four or five out of fifteen adults required either the actual cautery or the sesqui-chloride of iron.[126]
CHAPTER IX.
OPERATIONS ON AIR PASSAGES.
Operations on the Larynx and Trachea.—The great air passage may be opened at three different situations, and to the operations at these different places the following names have been given:—
Laryngotomy, when the opening is made in the interval between the cricoid and thyroid cartilages, through the crico-thyroid membrane.
Laryngo-tracheotomy, when the cricoid cartilage and the upper ring of the trachea are divided.
Tracheotomy, when the trachea itself is opened by the division of two, three, or more rings.
