The Treatment of Parturient Paresis with Iodide 
of Potassium \_E. Hauptmann ~\.—The action of iodide of 
potassium in parturient paresis is proved without any doubt. 
The mode of administration of this specific remedy, as first 
recommended by Schmidt-Kolding, has been modified. By the 
administration of Lugol’s solution (1 gin. iodine, 5 gm. iodide 
of potassium, and 100 gm. sterilized water, 25 gm. of this to be 
injected into each teat of the mammae) as used and recom¬ 
mended by Kunnemann, the author recorded 10 cases of bad re¬ 
sults from this treatment, in spite of the fact that it was used in 
every case during the early stages of the disease. Dr. Peter in 
a recent article advises the introduction of the iodide of potas¬ 
sium directly into the blood circulation. He injected in the 
time of 10 minutes 10 gm. of iodide of potassium, in 2000 gm, 
of steiilized water, at the temperature of 38° C. intravenously. 
This method was successful in several cases. The injection into 
the mammae or jugularis requires great care and strict asepsis, 
which is often, even for the professional man, not practicable. 
These difficulties caused Hauptmann to experiment on the in¬ 
ternal administration of the iodide of potassium, and, as he 
states, with the best results. The drug was given in a clear 
solution. In case some should escape into the trachea, it would 
cause no harm, on account of the complete solubility of the 
iodide of potassium. By this procedure Hauptmann obtained 
as good results as by the Schmidt treatment. The action of the 
iodine manifests itself at the same time as when injected into 
the mammae. In case the action is delayed, in eight hours the 
dose can be repeated, or reduced to half, depending on the cir¬ 
cumstances. The dose was about 10 gm. with a slight varia¬ 
tion, depending on the weight of the animal, which was accord¬ 
ingly regulated. As heart stimulants digitalis was given in the 
form of tincture, coffeinum natriosalicylicum, ammonium car- 
bonicum, and alcohol were also used. The further experiments 
in introducing the iodide of potassium by the way of the uterus, 
which, as known, has a great power of resorption, proved also to 
be successful, having the same curative effects and also the same
