A trial of a hydrocolloid dressing in the management of indolent ulceration

Abstract

A report of a randomised, controlled trial of a hydrocolloid dressing used in the treatment of leg ulcers that were failing to heal.

Efficacy of modern dressings in the treatment of leg ulcers: A systematic review

“…From those included, 22 studies 30–51 evaluated the use of modern vs. conventional dressings, and nine 52–60 were comparative studies of different modern dressings. Twenty‐six studies 30–48,52–58 corresponded to ulcers of venous origin and five 49–51,59 , 60 to leg ulcers whose etiology was not clearly identified. No study that exclusively targeted arterial ulcers and met the inclusion criteria was identified.…”

“…Five studies 36,37 , 52,54 , 59 made no reference to the size of the wound to be treated, and four failed to describe the baseline characteristics of the study population 36,37 , 44,59 . Seven studies made explicit mention of the fact that results were analyzed on an intention‐to‐treat basis 33,38 , 42,44 , 47,53 , 60 and only two 40,42 described the a priori calculation of the number of patients needed in order to be able to detect a clinical difference as statistically significant.…”

“…Sixteen studies (Table 1) evaluated the complete healing of the wound and Figure 2 shows the variability in the percentage of healing obtained in the intervention and control groups in each such study by duration of treatment. Joint analysis of the eight studies (with 782 participants) that examined hydrocolloid dressings vis‐à‐vis gauze with paraffin or povidone iodine, 30 nonadherent knitted viscose, 31,40 , 42 paraffin‐soaked gauze, 38,45 or Unna's boot (gauze mesh impregnated with zinc oxide, calamine, and gelatin; ConvaTec, Skillman, NJ) 35,39 revealed no statistically significant differences in healing rates between the respective hydrocolloid dressings and conventional treatment (Figure 3).…”

“…Withdrawals showed a great difference between studies, yet the pooled analysis of the 12 studies with 955 participants 30,32,33,35,38–40,44–48 that provided data failed to attain significant differences between the intervention group with modern dressings (22%) and the conventional group (17%; RR 95% CI: 1.20[0.76,1.89], P = 0.4).…”
