Pressure Sores - Treatment for Pressure Sores/Ulcers
Treatment for pressure ulcers can vary, depending
on the grade of the ulcer.
Treatment options may include regularly changing
your position, or using special mattresses and dressings
to relieve pressure or protect the skin. In some cases, surgery may be needed.
Pressure ulcers are a complex health problem
arising from many interrelated factors. Therefore, your care may be provided by
a team comprising different types of healthcare professionals. This type of
team is sometimes known as a multidisciplinary team (MDT).
Your MDT may include:
- a tissue viability nurse (a nurse who specialises in wound care and prevention)
- a social worker
- a physiotherapist
- an occupational therapist
- a dietitian
- medical and surgical experts with experience in pressure ulcer management
Changing position
It's important to avoid putting pressure on areas
that are vulnerable to pressure ulcers or where pressure ulcers have already
formed. Moving and regularly changing your position helps to prevent pressure
ulcers developing and relieves the pressure on the ulcers that have
developed.
After your risk assessment is completed, your care
team will draw up a "repositioning timetable", which states how often
you need to be moved. For some people, this may be as often as once every 15
minutes. Others may need to be moved only once every two hours.
The risk assessment will also consider the most
effective way of avoiding putting any vulnerable areas of skin under pressure
whenever possible.
You may
also be given training and advice about:
- correct sitting and lying positions
- how you can adjust your sitting and lying position
- how often you need to move or be moved
- how best to support your feet
- how to maintain good posture
- the special equipment you should use and how to use it
Mattresses and cushions
There are a range of special mattresses and
cushions that can relieve pressure on vulnerable parts of the body. Your care
team will discuss the types of mattresses and cushions most suitable for you.
Those thought to be at risk of developing
pressure ulcers, or who have pre-existing grade one or two pressure ulcers,
usually benefit from a specially designed foam mattress, which relieves
the pressure on their body.
People with a grade three or four pressure ulcer
will require a more sophisticated mattress or bed system. For example, there
are mattresses that can be connected to a constant flow of air, which is
automatically regulated to reduce pressure as and when required.
Dressings
Specially designed dressings and bandages can
be used to protect pressure ulcers and speed up the healing process. Examples
of these types of dressings include:
- hydrocolloid dressings – these contain a special gel that encourages the growth of new skin cells in the ulcer, while keeping the surrounding healthy area of skin dry
- alginate dressings – these are made from seaweed and contain sodium and calcium, which are known to speed up the healing process
Creams and ointments
Topical preparations, such as creams and ointments,
can be used to help speed up the healing process and prevent further tissue
damage.
Antibiotics
If you have a pressure ulcer, you will not
routinely be prescribed antibiotics. These are usually only prescribed to treat
an infected pressure ulcer and prevent the infection from spreading.
Antiseptic cream may also be applied directly to
pressure ulcers to clear out any bacteria that may be present.
Nutrition
Certain dietary supplements, such as protein, zinc
and vitamin C, have been shown to accelerate wound healing.
If your diet lacks these vitamins and minerals,
your skin may be more vulnerable to developing pressure ulcers. As a result of
this, you may be referred to a dietitian so that a suitable dietary plan can be
drawn up for you.
Debridement
In some cases, it may be necessary to remove dead
tissue from the ulcer to help stimulate the healing process. This procedure is known
as debridement.
If there is a small amount of dead tissue, it may
be possible to remove it using specially designed dressings and paste. Larger
amounts of dead tissue may be removed using mechanical means. Some mechanical
debridement techniques include:
- cleansing and pressure irrigation – where dead tissue is removed using high-pressure water jets
- ultrasound – dead tissue is removed using low-frequency energy waves
- laser – dead tissue is removed using focused beams of light
- surgical debridement – dead tissue is removed using surgical instruments, such as scalpels and forceps
- A local anaesthetic will be used to numb the area of skin and tissue around the ulcer so that debridement does not cause any pain or discomfort.
- Maggot therapy
During maggot therapy, the maggots are mixed into a
wound dressing and the area is covered with gauze. After a few days, the
dressing is taken off and the maggots are removed.
Many people may find the idea of maggot therapy
off-putting, but research has found that it is often more effective than more
traditional methods of debridement.
Surgery
It's not always possible for a grade three or four
pressure ulcer to heal. In such cases, surgery will be required to seal the
wound and prevent any further tissue damage occurring.
Surgical treatment involves cleaning the wound and
closing it by bringing together the edges of the wound (direct closure), or by
using tissue moved from a nearby part of the body (flap reconstruction).
Pressure ulcer surgery can be challenging,
especially because most people who have the procedure are already in a poor
state of health. There is a risk of a large number of possible complications
occurring after surgery, including:
- infection
- tissue death of the implanted flap
- muscle weakness
- Blisters (small pockets of fluid that develop inside the skin)
- recurrence of the pressure ulcers
- blood poisoning
- infection of the bone
- internal bleeding
- Abscesses (painful collections of pus that develop inside the body)
- DVT (a blood clot that develops inside the veins of the leg)
- Despite the risks, surgery is often a necessity to prevent life-threatening complications, such as blood poisoning and gangrene (the decay or death of living tissue).
