A six-point programme for the prevention and pressure therapy of hypertrophic scarring started in 1975 at Odstock Hospital. The work reported here includes a pressure calibration of batches of the material chosen for pressure bandaging; a pressure study of the bandages on volunteers' limbs; and the formation of a pressure therapy clinic. The clinic results were similar to those reported by Thomson (1974) and were considered sufficiently favourable to justify continuing the clinic and instituting a policy of close review and early therapy for all burns patients. The programme proved the accuracy of the pressure sensor and attempted to develop an objective method of recording progress. Arguments for pressure versus occlusion as the therapeutic agent are discussed and supported by a case report. It is suggested that a controlled trial of pressure therapy should be carried out.
