Wound Bed Preparation Using Unripe Pawpaw in a Resource-poor Environment: A Prospective Study.

Background: Chronic wounds affect mainly the productive age group in developing countries and stretch the limited healthcare facility. We aimed to establish the efficacy or otherwise of pawpaw dressing in management of common forms of wounds in resource-poor settings using the Nigerian pawpaw in humans.

Methods: This study was a prospective research carried out at Alex Ekwueme Federal University Teaching Hospital Abakaliki Nigeria between September 2019 and August 2020 using patients with lower extremity wounds. Thirty patients who had lower extremity wounds that required debridement were enrolled in the study after giving consent. They had wound dressing with unripe pawpaw as an enzymatic debriding agent to evaluate the rapidity of eschar separation and bacterial clearance. The data obtained with a proforma were analyzed using IBM SPSS.

Results: There were 16 males and 14 females with an average wound size of 127.13+ 103cm2. Eschar separation occurred earliest after 3 d of dressing and the latest after 14 d with a mean period of 5.5+ 2.255 days. A case had negative bacterial culture on the first test. Others had a variable period of clearance with a maximum of 18 d and a mean of 6.73+3.750 days. Both eschar separation and bacterial clearance correlated positively with the wound size.

Conclusion: Wound bed preparation with unripe pawpaw dressing showed promising outcomes with rapid eschar and slough separation, and bacterial clearance resulting in a faster wound healing. This is recommended for wounds needing debridement in which the patients are not fit for anesthesia or could not afford the cost of surgery.
