Hydrocephalus is a condition in which cerebrospinal fluid accumulates in the section of the brain called ventricle in much larger volumes than normal, causing the ventricle to be enlarged and the brain to be under pressure. Many of the children with hydrocephal us receive a surgery called the shunt surgery. There several points to be noted when children with shunt live our normallifestyle. In many cases of hydrocephalus emerging in childhood, it is treated by ventriculo.peritoneal shunt (V.P shunt) surgery. A shunt comprises of a valve and a catheter. By applying an external force , the valve and the catheter may be subjected to pressure. It may case the catheter to become deformed and clogged or damaged. Thus physical activities which may apply pressure on the valve or the catheter or cause some objects to hit them should be avoided. Since the pressure of a programmable valve is adjusted using magnetic force , it may be affected by magnets and so forth. Shunt system can cause shunt troubles. If shunt occlusion or shunt infection occurs, the patient will have symptoms such as headache, vomiting, dizziness, frustration, red swelling of the skin along the catheter and inability to keep balance of the body. If the above symptoms appear, we must suspect a shunt trouble. It may be necessary to caution other children to be careful with a child with shunt when they live together in kindergartens or nursery schools. When nursing children with shunts, the following precautions are required: CD Do not hit the valve or catheter in any way during physical activities. @ Avoid bringing magnets from coming into contact with the valve and strong magnetic fields. @ Do not miss the signs of shunt troubles. @ Inform other children to be careful.
