Case study
N=7

Population: Mean age = 44.4 yrs; Gender: males = 5, females = 2; Level of injury: paraplegia = 4, tetraplegia = 3; Location of pressure ulcer: trochanter = 3, sacrum = 4; Stage of ulcer: IV = 6.
Treatment: Topical negative pressure (TNP) applied continuously (125 mmHg), dressing changed every 4-7 days.  All patients seen and assessed by dietitian; nursed on a pressure redistribution surface; turned frequently; wound debrided as necessary pre-treatment.
Outcome Measures: Picture & wound swabs (every dressing change); Pressure ulcer volume (beginning and end of treatment).
  1. Within 1-2 days of treatment initiation, granulation tissue developed in all wounds.
  2. Wound volume and grade decreased (33-96%) in all subjects, but rate and extent varied. Bacterial colonization was also reduced in each wound.
  3. Limited dressing problems were described, although rashes and pain were reported in some.
  4. Seal preservation in certain areas, overlapping foam on healthy skin and pressure application on bony protrusions, were reported as practical problems.
