2141. Therapeutic Uses

In the acute pain occasioned by the presence of a Stone in the Bladder, Dr. Prout* states that he has seen great temporary relief produced by a lotion composed of Liq. Plumb. Diacet. Dil. and T. Opii in equal parts, applied as hot as possible, by means of a sponge, to the perinaeum. Opium or other remedies, as indicated in each case, may be given internally at the same time. In Prostatorrha, Prof. Gross recommends the following injection: - ℞ Liq. Plumbi Diacet., Vin. Opii aa f3j., Aq. fx., M. To be used thrice daily.

2142. In Leucorrha, where there exists an acrid secretion, with heat and excoriation of the parts, a solution of the Sub-acetate (Liq. Plumb, fl. drs. ij., Aq. Oj.) forms an excellent sedative vaginal injection. It may be used warm or cold, according to the sensations of the patient. "In some cases," observes Dr. Locock, " it is better to introduce into the vagina a piece of lint soaked in equal parts of Liq. Plumb., Liq. Opii Sed. and Mucilage." (See also Vaginal Injections, part ii.)

2143. In Catarrh Of The Uterus, Prof

Strohl,§ of Strasburg, employs injections of Liq. Plumb. Diacet. Dil. into the cavity of the uterus. The safety of the practice is very doubtful. (See Uterine Injections, part ii.)

2144. Gangrene Of The Pudenda In Female Children Was Successfully Treated By

Mr. R. Wood, || who applied Liq. Plumb. Dil. and bread poultices made with the same lotion. When the ulcers were clean, they were dressed with Ung. Zinci.

2145. In Purulent Ophthalmia, Dr

Vetch¶ states that the undiluted Liq. Plumbi Diacet. is a most efficacious application. It has the advantage, he says, of being perfectly harmless; and although for fifteen or twenty minutes, it causes some irritation, when this subsides, its astringent and soothing effect is evident. In the Ophthalmia of Infants, a diluted solution (ex. - xv. ad Aq. fl. oz. j.) proves a useful collyrium. In some other forms of Ophthalmia, it also proves serviceable; but it is inadmissible in all cases where ulcerations of the cornea exist, as it is apt to produce an indelible opaque cicatrix.
