Hydrosurgery as a safe and efficient debridement method in a clinical wound unit

OBJECTIVE: Hydrosurgical debridement allows removal of non-viable tissue, preserving healthy tissues. This study was designed to analyse whether hydrosurgery, used in a clinical wounds unit, is an effective and safe method that may reduce debridement time. METHODS: Patients' wounds had the following characteristics: wounds with devitalised tissue needing rapid debridement, wounds with cavities, or non-healing wounds. Hydrosurgical debridement uses a pressurised stream of saline (0.9% sodium chloride) and a vacuum around this stream to remove the devitalised tissue of the wound, preserving healthy surrounding tissues. Superficial wounds were 43.4% of the total and 56.6% of wounds had cavities. Pain associated with the hydrosurgery was mild to moderate. There were no hydrosurgery-related adverse events. For effective debridement, the required sessions were as follows: one procedure (73.6%), two procedures (18.9%) and three procedures (7.5%). There was a statistical significant direct correlation (r=0.307) between the number of required sessions and wound size. All patients improved in a week (>80% of granulation tissue). CONCLUSION: We demonstrate that hydrosurgery is an effective and rapid debridement method that can be used safely in the outpatient setting.
