Effect of different frequencies of dressing change on efficacy in diabetic patients with stage III pressure sores

Objective To investigate the efficacy and medical fees of different frequencies of dressing change in diabetic patients with stage Ⅲ pressure sores.Methods Random number table was used to divide 62 patients with stage Ⅲ pressure sores into the observation group (31 cases) and the control group (31 cases).75％ alcohol together with resins draconis was mixed into pasto and applied on the wound,and thtan viscose foam dressing was applied on the outer layer.The dressing was changed every 5 days in the observation group and every 3 days in the control group.Results Effective rate was 94.1％ of the observation group and 97.1％of the control group.There was no significant difference between the two groups ( x2 =0.796,P ＞ 0.05 ).Average cost of dressing use was ( 1 67.7 ± 14.5 )Yuan in the observation group and (277.9 ± 18.9 ) Yuan in the control group; Average frequency of dressing use was ( 4.2 ± 1.2 ) times in the observation group and (6.7 ± 1.5)times in the control group.The differences were statistically significant (t =27.486 1,7.588 7,respectively;P ＜ 0.05 ).Conclusions Among combined application of resina draconis and foam dressing in patients with stage Ⅲ pressure sores,lower frequency of dressing use does not reduce treatment outcome but reduces the patients' economic burden and nurses' workload and avoids the patients' discomfort during dressing change.
