Objective To observe the clinical efficacy and inflammation of tangential excision within 24 hours after burn with massive deep Ⅱdegree burn wounds for elderly patients. Methods From Jan. 2010 to Dec. 2013, a total of 82 elderly patients with massive deepⅡdegree burn wounds were divided into the observation group ( giveing tangential excision within 24 hours after burn) and the control group ( giveing tangential excision within 3~5 d after burn) according the time of tangential excision treatment. The amount of infused fluid, u-rine, levels of serum inflammatory factors, survival rate of skin grafts, wound healing time, hospitalization time and the complications were compared between the two groups. Results There was no significant difference in the amount of infused fluid, plasma and urine between the two groups in the first day and fifth day (P>0. 05). The levels of TNF-αsignificantly decreased after 3 days of therapy compared with the control group (P<0. 05). The levels of IL-6 significantly decreased and IL-10 significantly increased from the first day of therapy in the ob-servation group compared with the control group (P<0. 05). The survival rate of skin grafts in the observation group was significantly higher than that in the control group, and time of wound healing and hospitalization in the observation group was significantly shorter than that in the control group (P<0. 05). The complication rate of the observation group was 11. 1% which was significantly lower than that in the control group 29. 7% (P<0. 05). Conclusion To treat burn with massive deepⅡdegree burn wounds for elderly patients with tangential excision within 24 hours which can effectively reduce the inflammatory, reduce wound infection and improve the success rate of skin grafting.

From September 2013 to October 2018, 39 patients (28 males and 11 females, aged 21 to 76 years) with stage 4 pressure ulcers were admitted to the General Hospital of Xinjiang Military Command. The area of pressure ulcers ranged from 2 cm×2 cm to 20 cm×12 cm on admission. The two-stage method of debridement and skin flap transfer was exploited to repair the wounds. In the first stage, a thorough debridement was performed (26 cases underwent debridement once, 10 cases twice, and 3 cases for three times). The skin flap transfer surgery was conducted in the second stage after 6 to 12 days (local skin flap for 16 cases, vascularized island flap for 8 cases, fascial flap for 5 cases, gluteus maximus flap for 5 cases, and biceps femoris flap for 5 cases), with flap area of 4 cm×2 cm to 16 cm×10 cm. Some donor sites were closed by direct suture and the other donor sites which can not be sutured were covered by medium-thickness skin graft from the lateral thigh. All the pressure ulcers of 39 cases were healed with no sinus. During follow-up of 6 months to 5 years, no recurrence of pressure ulcer at the surgical site was observed; the flaps achieved soft texture and good appearance. Thus, the two-stage method of debridement and skin flap transfer achieved good long-term curative effect and could be a preferable option for treating stage 4 pressure ulcers.
