CHLORAL. 331 ;

Dose.—Of hydrate of chloral, gr. v to gr. xx ; and it must be
remembered that one-half drachm has produced poisonous symp-
toms. Thirty grains of hydrate of chloral are equal in effect to
gr. j of opium. For adults, if short intervals of sleep are re-
quired, from gr. xx to xxx will answer j for young children, gr.
vij is the dose recommended. Moderate and frequently repeated
doses are better than a single large one.
Dental Uses.— In dental practice, the hydrate of chloral, in the
is applied to inflamed pulps for the relief
form of gr. ss to gr. j,
of odontalgia, and is an efficient remedy ; it is also employed for
the relief of neuralgia of the fifth pair of nerves ; as a stimulant
and deodorizing application to foul and fetid indolent ulcers
also as a local anaesthetic, for this purpose being combined with
camphor and other agents (see Aconite), (see Camphor); also as
an anodyne, for the relief of the pain of periodontitis ; and as an
injection, for alveolar abscesses. It is also used as a lotion (when
diluted with water) for inflammations of the oral mucous mem-
brane, and as an antiseptic (chloral, 5j ; aqua, f^ij) for injecting
putrid pulp-canals and chronic alveolar abscesses. Although it
is employed hypodermically, yet painful phlegmons have resulted
from its repeated application.
Chloral Phenol.—When chloral is combined with carbolic acid
it liquefies, and a preparation composed of equal parts of phenol
and chloral is used for odontalgia as well as for its antiseptic
qualities. Chloral Phenol is a colorless, clear liquid, soluble in
alcohol, acetic acid, amyl-alcohol, chloroform, carbon, glycerin
and ether. It possesses the odor and taste of its constituents.
Chloral has the property, when rubbed with certain bodies,
such as camphor, of forming there with syrupy liquids. With
phenol (absolute carbolic acid) it also liquefies, and a preparation
composed of equal parts of phenol and chloral is used in dentistry
for allaying toothache, as well as for its antiseptic properties. A
recent study by Fabini, says the Chemist and Druggist., shows that
chloral-phenol possesses the odor and taste of its constituents, and
when applied to the skin produces inflammation and an eruption
of small blisters. It is a colorless and clear liquid, having a sp.
gr, at 20° C. of 1.289, ^^ ^^^^ '^ sinks in anhydrous glycerin.
