Pulse Voltage Electrical Stimulation for Bacterial Inactivation and Wound Healing in Mice with Diabetes.

BACKGROUND

Treatment of wounds in diabetes often gets less than perfect healing. One of the reasons for the difficulty in treating wounds in diabetes is the growth of aerobic and anaerobic bacteria. This study aims to determine the pulse voltage and treatment time that can optimally inactivate bacteria, and their effect on wound healing in mice suffering from diabetes.

METHODS

The study used electrical stimulation with a direct voltage of 10 given a pulse voltage of 50-80 , a width of 50 s, and the number of pulses of 65 per second. The research samples were () and () bacteria that grew on beef and mice () with diabetes. The treatment for and bacteria was carried out using a pulse voltage of 50-80 volts for 5-15 and repeated for 3 days. Meanwhile, treatment of mice wounds was carried out with a pulse voltage of 80 volts for 15 and repeated for 7 days.

RESULTS

The results showed that treatment with a pulse voltage of 50-80 and a treatment time of 5-15 significantly reduced the number of and bacteria in beef (p≤0.05). Treatment with a pulse voltage of 80 for 15 made beef free from bacteria. Meanwhile, treatment with a pulse voltage of 80 for 15 per day for seven days resulted in the wound state of three mice in the maturation phase and two mice in the proliferation phase on day 8 with an average wound area of 0.108 .

CONCLUSION

The treatment with a pulse voltage of 80 for 15 made the beef sterile, the mice wounds healed quickly, and the mice not stressed. The higher the blood glucose level, the slower the wound healing process.
