High Concentration of Sugar Solution Irrigation Promotes the Healing of Infected Wound

Study Overview
=================
Brief Summary
-----------------
Surgeons easily get wound infections. Most wound infections will be cured by applying medicines and changing dressing in very short period of time. But some wounds are severely contaminated combined with fat liquefaction, crateriform ulcer and large undermined lacuna, so changing dressing takes a very long time. In order to better change the dressing, it needs to expose the wound thoroughly, which requires to completely open the healed skin, so the healing will be slowed down. Some scholars lay stress on prevention. Wound infection control concerns prevention--not therapy--of an infrequent but expensive kind of surgical morbidity.(1.2)Some scholars think that the main armamentarium of the attack is the use of topical anti-infectives, which invade the bacteria where they reside, and, consequently, reduce their numbers and promote wound healing.(3)For example, silver is reemerging as a viable treatment option for infections encountered in burns, open wounds, and chronic ulcers. But it is expensive and is difficult to acquire silver-containing dressings. And Recent findings, however, indicate that the compound delays the wound-healing process and that silver may have serious cytotoxic activity on various host cells. (4) As High concentration of sugar solution, honey appears to heal partial thickness burns more quickly than conventional treatment (which included polyurethane film, paraffin gauze, soframycin-impregnated gauze, sterile linen and leaving the burns exposed) and infected post-operative wounds more quickly than antiseptics and gauze.(5)This study involve the use of another high-concentration of sugar solution (HCSS) to lavage infected wounds when changing dressings.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

| Active Comparator: High concentration of sugar solution<br>Lavage group of high-concentration sugar solution (HCSS): disinfected the Skin outside wound with conventional PVP. HCSS refers to supersaturated sugar solution made of 50% high-concentration glucose and white sugar. Prior to wound irrigation, dry cotton balls are used to wipe the wound and internal lacuna, to clean some necrotic tissues out of the wound. HCSS is applied on the wound once a day, and whether the lavaging is stopped based on the amount of exudation from the wound. | Procedure: High concentration of sugar solution<br> <br> |
| Active Comparator: conventional surgical dressing change<br>conventional surgical dressing change:separated suture, expanded the wound, placed drainage ribbon gauze and used hydrogen peroxide or(and) PVP to wash the wound; the decision-making power of these operators is determined by a doctor. After the doctor confirms granulation cleaning in the wound, the decision-making power of suture is also determined by a doctor. | Procedure: conventional surgical dressing change<br> <br> |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Duration of wound healing | It means the time from the first day after incision infection is found out to continuous dressing change in the last time. If the wound is kept in the infection status, it requires changing it for the wound once a day. For phase II suture on the open incision, the last time of dressing change should add the following days. Abdominal incision should increase 5 days. The wound of four limbs should increase 10 days. | 4 weeks | 
| The scoring on the open wound | Without separating suture, only the wound is shoved off within 2cm for 1 score; with separating suture, but the distance is kept in 2cm for 2 scores; with separating suture, the wound is shoved off for 2-3cm for 3 scores; In a similar fashion, the highest one is 10 scores. For patients with the longer wound and disconnected openness, the overall length of the wound should be overlapped. According to the overall length, scores are conducted as the above-mentioned rules. | 4 weeks |
