INTRA TRACHEAL INJECTION OF SALINE SOLUTION IN WEAK¬ 
NESS OF THE HEART. 
By Dr. Motz, V.S. 
Subcutaneous injections of saline solutions having been 
advantageously used in human practice, as a cardiac stimu¬ 
lant, Motz experimented with it on horses, employing the in- 
tra-tracheal injection as a better mode of administration. Pie 
reports the following case : 
A horse which had suffered from influenza, and had been 
ill for six weeks, showed, when first examined, great weak¬ 
ness, and frequently fell down. The cephalic mucous mem¬ 
branes were very pale, the pulse scarcely perceptible, and 
intermitting every third or fourth beat. Examination of the 
lung revealed nothing abnormal. The heart sounds corres¬ 
ponding to the perceptible beat of the pulse, were normal, 
and during the intermission there was an indefinite cardiac 
murmur. In order to combat the apparent weakness of the 
heart, fifteen grammes of common salt were dissolved in one 
hundred grammes of boiled water; the lotion was filtered, 
and thirty grammes of it were injected into the trachea. 
Within a quarter of an hour thereafter the pulse became 
fuller and stronger, and intermitted only every seventh or 
eighth beat. Hie injection was repeated after an hour, and 
doses of iron were administered with the food. On the sec¬ 
ond day the weakness had abated, the appetite was better, 
and the animal fell only once. The injections were continued 
for three days, when a permanent improvement took place, 
the pulse continuing to be strong and without intermis 
sions. 
Since then Motz has repeated this mode of treatment in 
eight cases of notable weakness, occurring in the course of 
attacks of influenza. Within half an hour the pulse always 
diminished in frequency, and this effect continued for eight 
and ten hours, after which a second injection was given. 
Further reports are recommended. — Biol. Thierarz-
