Objective:
To explore the efficacy and safety of bioactive material (combest) which is combinated with bioglass and hyaluronan on burn wound healing.
Methods:
From March to September 2006, 20 patients were treated; including 16 males and 4 females, aging 18-58 years(40 years on average). The wounds were classified as deep degrees II in 7 cases, granulated wounds in 9 cases and graft site wounds in 4 cases. Twenty wounds in one side were repaired with Combest as the test group and 20 wounds in the other side with blank cream as the control group. The wounds in size ranged from 2.0 cm x 1.5 cm to 40.0 cm x 20.0 cm. The wound healing rate was observed, and the blood test and the indices of hepatic and renal function were determined on the 1st, 3 rd, 6 th, 11 th, 16 th and 21 st days of treatment.
Results:
Wound healed within 3 weeks in 11 cases of the test group (3 cases on the 11 st day, 4 on the 16 th day, and 4 on the 21 st day) , but no wound healing was observed within 3 weeks in the control group. The healing size accounted for 2/3 of wounds in 18 cases of the test group and in 1 case of the control group. The excellent and good rates were 95%(18 cases and 1 case) in the test group and 50% (1 case and 9 cases) in the control group, showing significant difference (P<0.01). For all patients, no obvious changes were found in the blood test and hepatic or renal function indices.
Conclusion:
Combest combinated with bioglass and hyaluronan is beneficial to the proliferation of the granulation and wound healing with good safety.

Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
