WARM WATER INJECTIONS FOR THE REMOVAL OF THE 
PLACENTA. 
By Mr. Laurent. 
These injections, at a temperature of forty to fifty degrees, 
conveyed beyond the neck of the uterus with an india-rubber 
tube, are strongly recommended by the author. By using this 
tube, the lavatory is carried quite to the bottom of the uterus, a 
result which it is impossible to obtain with any ordinary syringe. 
The tube is attached to a funnel containing about five quarts of 
liquid, which is injected three times a day. The placenta is 
usually expelled in two days. 
If the expulsion has been delayed beyond the fourth or fifth 
day, and the secundines are in a state of decomposition, there is 
danger in the introduction of the hand and arm into the putrefied 
mass, even when it has been previously oiled; and it is then that 
the use of the india-rubber tube becomes most advantageous. A 
disinfecting liquid of permanganate of potash is then used. The 
operation consists in injecting, as far in as possible, about five 
quarts of warm water containing from one-half to one gramm of 
the manganate, when the mass being thus as it were disinfected, 
can be readily removed by the hand introduced into the uterus. 
In conclusion, in order to accomplish a complete injection 
into the uterus, the tube is not convenient merely, but necessary 
and indispensable. It is the only instrument which can be car¬ 
ried so far into the organ without danger , and it facilitates the 
washing of all the cotyledons with either pure water or disinfect¬ 
ing liquids, and thus stimulating the uterine contractions and 
effecting the expulsion of the placenta.— Joum. de Soc. Scientif.
