| Aim: To test the efficacy of green tea with that of conventional topical metronidazole powder by comparing the rate of malodorous score reduction using the verbal numeric scale (VNS).
Methods: This was a prospective randomised experimental study comparing two types of odour control agents used for treating malodorous fungating malignant wounds in a tertiary hospital in Singapore. Patients were randomised to either control (metronidazole power) or treatment (green tea) group and was follow-up with a daily dressing for a week by a designated nurse. Both patient and designated nurse would rate the malodorous score daily on a VNS of 0 (no smell) to 10 (worst smell that one can imagine). Results: Thirty cancer patients with malodorous fungating wounds were randomised into either treatment (n=15) or control group (n=15). The location of wounds were breast (n=24), neck (n=2), groin (n=2), spine (n=1) and anus (n=1). All patients in both groups showed improvement in odour control by Day 7. Treatment group was as effective as control group and there was no statistical significance (p>0.05) to demonstrate which treatment is more superior. Conclusion: Green tea dressing is as effective as conventional topical metronidazole powder in controlling odour. Green tea is cheap, easily available and has no risk of drug resistance over long term use. Alternatively, it can also be used interchangeably with metronidazole powder to reduce the risk of drug resistance. |
