Analgesic efficacy of an ibuprofen-releasing foam dressing compared with local best practice for painful exuding wounds.

Objective: To examine if wound aetiology has an effect on the pain-relieving properties of an ibuprofen-releasing foam dressing, which was previously shown to reduce pain in wounds of various aetiologies, compared with local best practice (LBP). Method: This was a secondary analysis of data from a multicentre, randomised, parallel group trial of patients with painful exuding wounds of various aetiologies. Wound aetiology was determined at enrolment. Of 853 patients enrolled into the trial, 688 belonged to a wound aetiology subgroup that included > 25 patients and were included in the analysis reported here. Patients were randomised to a dressing containing 112.5mg of ibuprofen (ibuprofen foam) or to LBP for 5 days. Patients recorded pain relief and pain intensity daily. The main endpoint was the proportion of patients who, from day 1 to day 5, reported a summed pain relief score > 50% of the total maximum pain relief score (TOTPARD5>50%) and the corresponding number needed to treat (NNT) for each wound ae...
