Hyperbaric oxygen therapy in adriamycin extravasation: an experimental animal study

Area of Science:

• Biomedical research
• Wound healing studies
• Hyperbaric medicine

Background:

• Adriamycin extravasation causes severe tissue damage, including necrosis and nerve injury.
• Previous studies on hyperbaric oxygen (HBO) for adriamycin-induced lesions yielded conflicting results.

Purpose of the Study:

• To investigate the efficacy of hyperbaric oxygen (HBO) in promoting the healing of adriamycin-induced skin wounds.
• To evaluate the impact of HBO on lesion size and wound closure rates in a rat model.

Main Methods:

• Ninety-five Wistar-Albino rats received subcutaneous adriamycin injections.
• The experimental group (n=43) received twice-daily HBO treatment (2.5 ATA, 80 min) for 28 days.
• A control group (n=42) received no therapy; lesion sizes were monitored for 4 weeks.

Main Results:

• No significant difference in lesion size was observed between groups at days 7 and 14.
• Lesion size was significantly smaller in the HBO group on days 21 and 28 (p < 0.05).
• Complete wound healing occurred in 16/36 rats in the HBO group by day 40, versus 0/36 in the control group.

Conclusions:

• Hyperbaric oxygen (HBO) demonstrates a beneficial effect on healing adriamycin-induced skin lesions.
• HBO therapy accelerates wound healing and increases the rate of complete wound closure.
• This study supports the use of HBO as a potential therapeutic intervention for managing adriamycin extravasation injuries.
