Debridement methods efficacy for the second stage pressure ulcers treatment in outpatient department

Abstract

Aim: We aimed to analyze debridement methods efficacy for the treatment of patients with II stage pressure ulcers (PU). Method: Retrospective analysis of 60 patients’ case reports, treated for PU in single center, was performed. Group A (32 patients; PU stage II, covered with necrosis layer) underwent chemical debridement with moistened povidone iodine solution gauzes dressings. Group B (28 patients; PU stage II, covered with debris) was treated with hydrocolloid dressings to promote autolytic necrectomy. The study was performed between 2014 09 - 2016 09. We evaluated PU healing time and wounds’ clinical parameters (localization, size, persistence of necrosis, infection signs). Results / Discussion: There were 23 male patients and 9 female patients in chemical necrectomy group and 21 males and 7 females in other group respectively. 83 % of PU in both groups was home-acquired whereas 17 % evolved in previous health care facilities. 48 % of analyzed PU was in ischial region, 22 % sacral, 19 % trochanteric and 11 % heels. The mean diameter of PU was 3.2 cm. Groups were homogenous according to patients’ age, sex, wounds localization and size (p<0.05). In chemical debridement group the mean of healing time was 6.8 weeks and no presence of infection was mentioned. In hydrocolloid dressings group PU healed within 4 weeks. Two PU treated with hydrocolloids were excluded from study because of infection. Conclusion: Controlled autolytic necrectomy with the help of hydrocolloid dressings is the effective tool for the treatment of II stage PU in outpatient unit.
