1904 Excerpt: ...In the eatheterized specimen, obtained by ureteral
catheterization, it does render us assistance, especially where
used in connection with the other well established methods. The
freezing point of urine is influenced by diet, liquids, exercise
and elimination through other channels, as emesis, diarrheas,
perspiration, etc. CRYOSCOrY OF THE BLOOD. The cryoscopic
examination of the blood gives us more valuable information,
because it has been found that the freezing point of normal blood
is practically constant, varying from--0.55 to--0.57 C, the average
being--0.56 C. Any marked change in the freezing point of the blood
at once tells us that there is something wrong, and that we must
look, first of all to the functional activity of the kidneys, since
it has been found that interference with the proper excretory
function of the kidneys causes a concentration of the blood, hence
a lowering of its freezing point. The amount of blood required for
determining the freezing point is about 10 cc, and is readily
obtained by puncturing one of the larger veins in the forearm. The
skin is washed with soap and water, alcohol and ether, the veins
constricted above, and the needle of a Luer syringe is plunged
under the skin, as in giving a hypodermic, and then introduced into
the vein. Gradual suction is used in drawing the blood by slowly
withdrawing the piston. When the required amount is obtained (10 or
12 cc.) the constrictor is removed, the needle quickly withdrawn,
and gentle pressure made over the point of entrance. This is later
sealed with collodion. Tt causes no inconvenience to the patient
and may be done painlessly by using a little ethyl bromide or
chloride spray. In over 300 punctures, I have not met with a single
accident or objection from the patient. The w...
