Formulae for the Preparation of Surgical Materials.

(By F. W. Parham, M. D., Visiting Surgeon, Charity Hospital, New Orleans.)

A. - solutions.

I. Acid Sublimate solution.

1. The concentrated solution, as per following:

3212

℞ Hydrargyri chloridi corrosivi ..............Э iv

Acidi hydrochlorici c. p......3 vj

Aquae.........q. s. ad ℥ viij

M. S. Each ounce contains 10 grains of corrosive sublimate.

3213

2. The irritating solution: One ounce of the concentrated solution with water q. s. ad. Oij. will be 1 to 1,536, which is convenient, because easy to prepare extemporaneously: called 1 to 1500 solution. Other solutions may be made from this by adding any desired quantity of water.

- Dr. Ernest Laplace.

II. Carbolic Solution.

3214

℞ Acidi carbolici c. p........℥ j

Aquae........q. s. ad ℥ xxxiij

M. S. Approximates closely a 3 per cent solution.

III. Iodoform-ether (8 per cent, solution).

3215

℞ Iodoformi (vide B I).......Э ii

Etheris............ ℥ ij

M. S. As directed.

Uses: For thoroughly covering a surface with iodoform, the ether rapidly evaporating, On fresh raw surfaces causes severe pain.

N. B. - If kept on too long will cause vesication, owing to large amount of iodine generated.

IV. Iodoform-glycerin Emulsion.

3216

℞ Iodoformi............ 50

Glycerini.............30

Aquae.............. 30

M. S. Shake before using. Uses: For filling cavities and for injecting cold (tubercular) abscesses, when the ethereal solution would be considered objectionable on account of pain and danger of causing sloughing.

V. Iodoform-collodion (8 per cent, solution).

3217

℞ Iodoformi............Э ij

Collodii flexilis.......... ℥ j

M. S. To be used as directed.

Uses: For hermetically sealing aseptic wounds.

N. B. - If kept on too long may vesicate severely.

VI. Aseptic Salt Solution (6 per mille solution).

3218

℞ Sodii chloridi........gr. xlvj

Aquae.......... q. s. ad Oj

M. S. Boil for one-half hour. Keep in a Florence flask, stopped with sterilized cotton.

Uses: 1. Where an antiseptic solution is considered objectionable, or for the final washing of a previously antiseptically-washed wound.

2. For saline transfusion raise to a bloodtemperature.

N. B. - It is well to filter this solution before boiling, especially if to be used for the second purpose.

VII. Alcoholic Ether Solution of Iodoform.

3219

℞ Alcoholis et etheris partes equales iodoformi (vide B I.) q. s. ad. sol. sat.

M. S. To be kept closely corked.

Uses: For keeping silk (vide D II.) and catgut (vide D I.)

N. B. - Should be changed occasionally, owing to generation of iodine. Silk kept in this solution for a long time is more easily broken. Best prepared in small quantities.

- Dr. Dawborn.

VIII. Alcoholic Watery Solution of Sublimate.

3220

℞ Hydrargyri chloridi corrosivi ...........gr. v

Aquae...........℥ iij - 3 ij

Alcoholis.........q. s. ad Oj

M. S. Solution of 200 parts water and 800 parts alcohol, for sterilizing and keeping catgut. Uses: 1. For preserving rubber drains. 2. For disinfecting catgut.

- Bergmann.

IX. Alcoholic Solution of Sublimate.

3221
