Abstract
OBJECTIVE: To assess use of an adjunctive topical haemoglobin spray in the treatment of sloughy wounds. METHOD: In addition to a standard wound care regimen, consecutive patients with sloughy wounds self-administered haemoglobin spray treatment twice a week until the wound was healed. All patients were followed-up for 26 weeks. Results were compared with a retrospective cohort of 100 consecutive patients, treated during the same period the previous year with standard wound care alone. Data were collected on wound characteristics including percentage of slough, exudate levels, wound pain, and wound size. RESULTS: After 26 weeks, 94/100 patients (94%) treated with haemoglobin spray were completely healed compared with 63/100 control patients (63%). Positive results were evident as early as week one with 52% mean wound size reduction using the heamoglobin spray versus 11% in the retrospective control (p<0.001). At baseline, mean slough coverage was higher in the haemoglobin group, 58% versus 44% in the control group (p<0.001). By week four, mean slough coverage was 1% in the haemoglobin versus 29% in the control group (p<0.001). Reductions in exudate and pain levels (p<0.001) were also observed. CONCLUSION: Overall, results of this evaluation showed the addition of adjunctive haemoglobin spray to standard wound care treatment achieved positive clinical outcomes for patients self-managing complicated sloughy wounds, by supporting reduction of wound exudate and slough within the complex multifaceted process of wound healing.
