|Abstract:||The aim of this study is to compare the effect of two dressings, namely daily gauze dressing and lipido-colloid dressing, in terms of the efficacy in treating traumatic digital wounds in an emergency department in Hong Kong. In this randomized controlled trial study twenty-eight patients and their traumatic digital wounds were examined over a period of seven months in an accidental and emergency department in a general public hospital. The twenty-eight subjects, in both sexes, had injuries to their fingers with tissue lost but were not indicated admission or suture. By a random selection of dressing, either lipido-colloid or daily gauze dressings were applied on the wounds. Dressing changes were done at a three-day interval and the wounds were assessed in terms of several wound-healing parameters including wound size, tissue status, surrounding skin condition, nature and amount of exudates, wound pain and occurrence of infection. Patients were further examined, so as to monitor the healing progress, until the wound closed or the patient withdrew from the study, whichever occurred first. Chi-square, t-test and repeated measures were used to find out the differences in the two groups. The main outcome measures were wound sizes, occurrence of infection and patients' perception of pain in various stages. The statistics showed little difference between two dressing groups, in terms of mean healing time, occurrence of infection and the pain score experienced by patients. However, a significant difference, being that the wound area decreased shapely, was noticed in day 12 (U = 61.0, p = 0.04). The result demonstrated that the subjects in the lipido-colloid group (mean = 2.6, SD = 7.6) had their wounds recovered at day 12, which was faster than the daily gauze dressing group (mean = 8.4, SD = 10.2). It appears that the lipido-colloid is compared favourably to the daily gauze dressing, although statistically this study did not find a difference in the occurrence of wound infection and patients' perception of pain. The change of practice to daily gauze dressing was justified.|
