Background: Pressure ulcer management is difficult for the patient, relatives, doctor, and nursing staff and requires enormous resources. Management of multiple pressure ulcers in the spinal cord injured patient is a near-impossible task, especially in resource-deprived environments. The paraplegic, with multiple pressure ulcers, will frequently be managed under palliative care ...
