Once your child is under general anaesthetic, the doctor will use a variety of imaging techniques, such as ultrasound or x-rays, to guide them. This may involve waking your child in the night to give them a drink which we recommend. It is equally important to keep giving your child food and drink until those times to ensure they remain well-hydrated and get adequate nutrition. You will be informed the night before the procedure of the time that your child should be ‘nil by mouth’ – in other words, have nothing to eat or drink before the anaesthetic. Fasting reduces the risk of stomach contents entering the lungs during and after the procedure. This is called ‘fasting’ or ‘nil by mouth’. It is important that your child does not eat or drink anything for a few hours before the anaesthetic. This procedure is usually carried out while your child is under a general anaesthetic. If a larger amount of fluid needs to be removed or the fluid is too thick to be removed through aspiration, the doctor may suggest drainage instead. The joints in the body can become swollen with excess fluid called synovial fluid which surrounds the bone surfaces reducing friction as the joint moves. Blood can collect inside the body following surgery, or as a result of trauma. Fluid can build up in the abdomen or chest, putting pressure on the internal organs. Sometimes other fluids can build up inside the body, for example, lymph fluid, which is part of the immune system. Pus can collect in the area of infection making your child feel unwell and in pain.
Pus is a liquid mixture of dead cells and exhausted white blood cells. As the body is fighting off an infection, the white blood cells form fluid (pus). This page from Great Ormond Street Hospital (GOSH) explains about the procedure to drain or aspirate fluid from the body, what it involves and what to expect when your child comes to the Interventional Radiology department for treatment.įluid can build up inside the body as a result of infection. Larger amounts or thicker liquid will need to be drained over a period of time using a thin plastic tube. Small amounts of fluid can be drawn off using a needle and syringe.
Keeping the wounded site clean and regularly dressing the site can help prevent pus formation. Q: How do you stop a wound from exuding pus?Ī: The only way to avoid a wound from exuding pus is to ensure that it does not get infected. These dressings should be changed every two days. Alginate dressings contain seaweed fibres and sodium, which absorbs excess liquid and form a gel that aids the healing process. Q: Which type of dressing is best for purulent drainage wounds?Ī: Purulent wounds require dressings that trap the exudate and balance the moisture in the wound site.
