In the study of the relationship between microcirculation and pressure ulcers, there is less continuous observation of skin microcirculation in bedsores patients. The hypotheses of this study were that in the three group, the bedridden with pressure ulcer healing (healing group), bedridden with pressure ulcer worsening (worsening group),and bedridden without pressure ulcer (bed group), the microcirculation will be different, and it will be related with change in ulcer size of pressure ulcers. The purpose is to observe the observation of reactive hyperemia after occlusion, to understand the five-week microcirculation changes, to compare the differences in microcirculation among different groups, and to explore the correlation between the assessment parameters. The post occlusive reactive hyperemia (PORH) was measured with a laser Doppler flow meter. After 3 minutes of general blood flow monitoring was performed on the skin of the sacrum, a pressure of 200 mmHg was applied for 5 minutes. After the release of pressure, the reaction perfusion was continued for 4 minutes . The parameters in this study were [1] Braden Scale [2] skin water and oil [3] ratio of maximum skin microcirculation before and after reactive hyperemia (hyperemia ratio) [4] ratio of skin microcirculation before and after reactive hyperemia (Integral ratio). The results of this study were no significant differences between the hyperemia ratio and the integral ratio in three consecutive biweekly comparisons. In the relation between ulcer and blood flow, the correlation coefficient between the ulcer change and the hyperemia ratio of ulcer healing was significantly correlated with 0.85. This indicates that the degree of instantaneous contraction of the microcirculatory wall in ulcer healing patients can be used as an observation of ulcer changes. There was no significant correlation is -0.09 and -0.10 for the worsening group between the ulcer size change and the blood flow hyperemia ratio and the correlation ratio of the integral ratios. In worsening gorup, microcirculation parameters cannot be used as an observation item for the degree of wound.
