I often get called to see patients with pressure sores. Pressure sores are a common problem for elderly patients with limited mobility. These patients are often bed-bound, and thus their joints and bony surfaces (heels, ankles, knees, buttock, elbows, etc.) are in constant contact with hard surfaces, leading to skin breakdown. This can worsen if not treated, and infections can develop. Relieving pressure on these areas by turning patients, changing postures, etc. is critical to treatment, as is proper nursing care for the sores.
Here is a very informative article written in ST’s Mind & Body, by Dr Barbara Rosario (Consultant Geriatrician, Changi General Hospital).
