When should you not wear a band aid?


Bandages are our best allies when we sprain or we have a wound that requires some protection and support, so in our medicine cabinet should never miss a bandage, but what are they, what are they for, how to use them? All this we will see later.

It is one of the basic materials we need in our first aid kit. The elastic bandage provides even and gentle compression on the tissue surrounding an injury to reduce pain and swelling; it also provides support to an injured area. You may need an elastic bandage for any of the following reasons:

Compressive bandaging

As a procedure or technique, it consists of wrapping a part of the body that is injured for various reasons. Currently its most frequent use is to cover skin lesions and immobilize osteoarticular injuries. But it is generally used in the treatment of wounds, hemorrhages, contusions, sprains, dislocations and fractures. It is a specific technique that allows maintaining certain functionality of the injured area without damaging it. Applied as a therapeutic technique, it aims to selectively and mechanically limit the mobility of a joint in the direction of movement affecting the injured structures of the peri-articular tissues.[2][3][4][5][6]

Used to exert a progressive compression at the level of an extremity, from the distal to the proximal part, in order to promote venous return. It is also used to limit the movement of a joint in the case of 1st degree contusions and sprains.

The first turn is made with a 45º inclination towards the root of the limb, the second one with an inverted inclination (45º in the opposite direction to the previous one), the third one like the first one, but advancing a few centimeters towards the root of the limb… thus, in a back-and-forth movement, the bandage is completed, which at the end has the appearance of a “herringbone”.

Rigid bandage

In a reductionist way, it is typical for us to speak of elastic bandages to refer to those that apply pressure during rest and exercise, adapting to the changing diameter of the calf, while we consider them inelastic bandages when their pressure at rest is low and increases in peaks with muscle contraction. If we only place a bandage of one type, elastic or inelastic, this may approximate its in vivo behavior. However, as we will see below, a bandage is more complex than a bandage.

The former is an inherent characteristic of any bandage. Any bandage placed on a leg will be a multilayer bandage, even if we only apply one bandage, as there will always be some overlap between layers.

If the bandage is not very stiff, there are no pressure peaks on movement, as it adapts to changes in the shape of the calf, with little resistance to increased muscle volume. The pressure under the bandage in these cases does not vary much between rest and activity (lower Dynamic Stiffness Index).

Varicose veins are swollen and slightly twisted veins that can be seen with the naked eye on the skin. In mild cases, they do not usually cause symptoms or complications, and some people seek to eliminate them for aesthetic reasons, especially because they appear more frequently in a part of the body that is usually visible: the legs.

Veins have valves that work to keep blood flowing smoothly to the heart. When these valves become damaged or injured, blood flow can be impeded, causing blood to pool in some areas. This pooling causes the swelling in the veins characteristic of varicose veins.

D.E.M.A. bandages are made of cotton and elastomer fabric for better support. They are adjusted by means of a fastener that maintains the level of tension during daily use, and there are two versions: light and reinforced.
