Blisters on the wound

If there is a wound on the body, it is easy to develop blisters if you do not pay attention to maintenance after bandaging. This is a tension blister. It is normal to have blisters on the wound. The flow of tissue fluid and blood will cause the formation of blisters. If this happens, it must be dealt with in time, otherwise it will infect other parts of the body. You can disinfect the wound with alcohol and then re-apply a Band-Aid to relieve the symptoms, but be sure to avoid getting it wet.

This is a tension blister, which is caused by the increase in local blood flow resistance after tissue injury, resulting in the exudation of body fluids and the formation of blisters. Since the tension in the lower limbs of the human body is greater than that in the upper limbs, standing for a long time will increase the tension in the lower limbs, so blisters after injuries are more common in the lower limbs. Treatment principles: After disinfection, puncture the blister from the upper and lower edges, apply gentian violet, apply pressure bandage, elevate the affected limb, and pay attention to proper rest. It will heal itself soon.

First, prepare medical cotton swabs and 75% medical alcohol. Take two cotton swabs, dip one in alcohol and gently scrub around the blisters. Use the other cotton swab to wipe around the scrubbed blisters again to absorb excess alcohol so that you can see clearly around the blisters. At this time, the disinfection of the blisters is completed.

Take a needle, a household sewing needle will do, place one end of the needle above the lighter, warm it with fire, then wipe the needle with medical gauze. This will sterilize the needle.

Use a clean needle to make a small hole on one edge of the blister. Be sure to puncture the area at the very edge. If you puncture the middle of the blister, only a small portion of the liquid in the blister can be squeezed out, and the rest will flow around the punctured hole and cannot be squeezed out at all.

Gently squeeze the edge of the other side of the blister hole. The liquid in the blister will flow out from the small hole. At this time, use medical cotton to wipe off the flowing liquid.

After squeezing out the liquid in the blisters, apply disinfectant or anti-inflammatory ointment evenly on the blisters. Be careful when applying it at this time, because the skin on the blisters where the liquid has been squeezed out is very fragile and can be easily torn.

Finally, wrap the blister with medical gauze and tie it gently on the outermost layer. Check the gauze frequently. If fluid is still accumulating in the blister, continue to squeeze out the fluid. The next step is to allow the wound to be ventilated and dry, so that it can recover faster.

Precautions

After squeezing the liquid out of the blister, be sure not to tear the skin there or make a large cut, as that will cause the wound to become infected and cause greater trauma.
