Plaster of paris making of bandages

Preparing Handmade Plaster Bandages

Aim

To prepare plaster of Paris bandages by hand.

Procedure

   1.  To make handmade plaster bandages, starched cotton bandages of three, four and six inches which are prepared specially for this purpose are taken. They are available in various surgical stores.

   2.  The ideal mesh size of these bandages for holding the plaster should have 28 to 32 threads to an inch.

   3.  The usual length of the bandages is three yards, four yards and five yards for widths of three, four and six inches size respectively.

   4.  Regular dental grade of plaster of Paris powder, which should be free of grit used. If lumpy, the plaster must be sieved before it is used.

   5.  To make the plaster bandage, the powder is rubbed thoroughly into the mesh of bandage, the first portion of bandage being rolled so loosely as to leave a half-inch space in the center. If this detail is neglected, the inside part will not become wet when the bandage is immersed in water. If the powder is not rubbed uniformly into the bandage, there will be dry spots in the bandage as it is applied.

   6.  As the bandage is rolled no more powder should be added then it is held by the mesh, and it must not be rolled tightly. If either of these mistakes is made, the bandage will remain dry after it has been placed in water, and as a result the plaster will crumble when it is applied.

   7.  If, however, bandage is rolled too loosely, it is difficult to prevent it from “telescoping” it may be wrapped in waxed paper or a paper-napkin, or a rubber band is used to prevent it from unrolling.

   8.  Plaster bandages should be handled carefully to avoid shaking the powder out of the mesh.

   9.  It is important to store them in a dry place as dampness ruins them.

            10.       A liberal supply of plaster bandages of various widths should be available in the hospital at all times as they cannot be made on short notice.
