Auflagedruckmessung in der Dekubitusbehandlung

Backround. Pressure relief is an important factor to determine the quality of antidecubitus devices. Many studies have been carried out to measure the interface pressure, but because the results differed markedly, we made a study to assess the measurement devices. Methods. Thesystems FSA, a device for internal use in the Luck company, the X-Sensor and an invasive subcutaneous pressure measurement over the os sarcum (COACH: piezoelectric probe, MIPM) were tested on 20 healthy volunteers (average age 27 years, average BMI 21.8). Results. The values of interface measurement showed obvious deviations from subcutaneous pressure in two cases (FSA +1.8%, Luck -33%, X-Sensor +65%) and some results showed extreme variations (FSA +18 mmHg, Luck -21 mmHg, X-Sensor +27 mmHg). Conclusions. The interface pressure measurement (with a few volunteers) is not suitable for a correct assessment of antidecubitus devices. Furthermore, the use of this method is not necessary to monitor pressure relief in intensive care patients. These systems can, however be useful in the training of nursing staff.
