High-voltage electric burns is refractory with high rate of amputation (46%) in early stage and unfavorable functional recovery in later stage. Little breakthrough has so far been made in this respect. From Jan. 1985 to Jan. 1996, ninety-six cases with high-voltage burns were treated in our department. Seventy-one cases of various tissue flap grafting were applied to treat early electric burns, among which sixty-four cases were successful. The amputation rate was reduced to 30%. Postoperatively, a long-term rehabilitation training at home was carried out. Most of them achieved a good appearance of the wounded sites and limbs and satisfactory ability to work or self-care. It was suggested that early thorough debridement of necrosis tissue, careful reservation of living tissue, appropriate choice of tissue flap and postoperative rehabilitation training were of great importance to achieve a good prognosis.
Objective To investigate the cl inical effect of Meek technique skin graft in treating exceptionally large area burns. Methods The cl inical data were retrospectively analysed from 10 cases of exceptionally large area burns treated with Meek technique skin graft from April 2009 to February 2010 (Meek group), and were compared with those from 10 casesof exceptionally large area burns treated with the particle skin with large sheet of skin allograft transplantation from January 2002 to December 2006 (particle skin group). In Meek group, there were 8 males and 2 females with an average age of 34.5 years (range, 5-55 years), including 6 cases of flame burns, 2 cases of hot l iquid burns, 1 case of electrical burn, and 1 case of hightemperature dust burn. The burn area was 82.6% ± 3.1% of total body surface area (TBSA). The most were deep II degree to III degree burns. The time from burn to hospital ization was (3.5 ± 1.3) hours. In particle skin group, there were 8 males and 2 females with an average age of 36.8 years (range, 18-62 years), including 5 cases of flame burns, 2 cases of hot l iquid burns, and 3 cases of gunpowder explosion injury. The burn area was 84.1% ± 7.4% of TBSA. The most were deep II degree to III degree burns. The time from burn to hospital ization was (4.9 ± 2.2) hours. There was no significant difference in general data between 2 groups (P gt; 0.05). Results The skin graft survival rate, the time of skin fusion, the systemic wound heal ing time, and the treatment cost of 1% of burn area were 91.23% ± 5.61%, (11.14 ± 2.12) days, (38.89 ± 10.36) days, and (5 113.28 ± 552.44) yuan in Meek group, respectively; and were 78.65% ± 12.29%, (18.37 ± 4.63）days, (48.73 ± 16.92) days, and (7 386.36 ± 867.64) yuan in particle skin group; showing significant differences between 2 groups (P lt; 0.05). Conclusion Meek technique skin graft has good effect in treating exceptionally large area burns with the advantages of high survival rate of skin graft, short time of skin fusion, and low treatment cost of 1% of burn area.
Objective To introduce the technique of esophageal intraluminal stenting and assess its effect on the prevention of development of stenosis in patients with esophageal burns. Methods Thirty-three patients were admitted less than 3 weeks after ingestion of caustic agents. The second-or third-degree injuries were confirmed by esophogoscopy in all cases, but one with esophageal perforation at admission. Esophageal stenting was performed in all patients and these stents were kept in place for 4 to 6 months. Results There was no death in the series. All patients had a normal intake of food after removal of the stents, and stricture was not found on barium swallow test. Follow-up from 1 to 60 months five cases developed esophageal stenosis from 2 to 3 months after extracting the stents. One of them responded to esophageal bougienage, the remaining 4 patients required esophageal reconstruction and took a normal diet postoperatively. The other 28 patients have a normal diet after the stent removal. Conclusion The esophageal intraluminal stenting is able to prevent the formation of stricture in the aftermath of esophageal burns and its effect will be enhanced plus administering isoniazid.
Objective To study the preventive measure of the subambient temperature burn by analysing the pathogenesis feature. Methods The cl inical data were analysed from 351 cases of subambient temperature burn between February 2004 and February 2009, including age, sex, burn season, burn factors, burn position, burn area, burn degree, treatment way, and wound heal ing. Results Subambient temperature burn occurred in every age stage. The susceptible age stages included infant, children, and the elderly. Female patients were more than male patients. The common burn reasons werehot-water bottle burn, honey warm keeper burn, and heating device burn. The peak season was winter. Lower l imb was the most common site of the subambient temperature burn. The deep II degree to III degree were the most common level, and the burn area was always small, often 1% of total body surface area. Most of patients were treated with changing dressings at cl inic and few patients needed hospital ization. Though the surface of wound could heal finally, and the wound healed well with no obvious scar in patients who received operation. Conclusion Subambient temperature burn is the frequently encountered disease in winter. Use of the warming articles should be cautious, at the same time safety awareness should be strengthened so as to decrease the incidence rate of subambient temperature burn and the injury degree.
ObjectiveTo investigate the effectiveness of Ilizarov technique in treatment of the clubfoot after burns.MethodsBetween March 2012 and February 2017, 12 patients (17 feet) with clubfoot after burns were treated with Ilizarov technique. There were 10 males (14 feet) and 2 females (3 feets) with an average age of 38 years (range, 18-52 years). There were 3 cases of left foot, 4 cases of right foot, and 5 cases of both feet. According to the Qin’s classification of clubfoot deformity, there were 5 feet of degreeⅠ, 9 feet of degreeⅡ, and 3 feet of degree Ⅲ.ResultsAll clubfeet were completely corrected without local skin necrosis, needle tract infection, or acroanesthesia. All patients could walk with a heavy load. Pationts were followed up from 4 months to 3 years (mean, 10 months). At last follow-up, according to the International Clubfoot Study Group (ICFSG) score, the effectiveness was rated as excellent in 7 feet, good in 7 feet, and fair in 3 feet, with the excellent and good rate of 82.4%.ConclusionUsing Ilizarov technique can gradually correct the clubfoot deformity with the advantages of minimal invasion, safeness, and simpleness.
ObjectiveTo investigate the feasibility and effectiveness of repairing temporal skin and soft tissue defects and reconstructing sideburns with superficial temporal artery composite perforator flap.MethodsBetween January 2018 and January 2019, 12 patients with temporal tumors were treated. There were 5 males and 7 females with an average age of 51 years (range, 37-68 years). There were 8 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma. The disease duration ranged from 3 months to 4 years (mean, 13 months). The area of residual wound after tumor resection was 3.8 cm×2.5 cm-5.2 cm×3.5 cm. The superficial temporal artery composite perforator flap was designed. The hairy superficial temporal artery frontal branch perforator flap was used to repair the hair growing area and reconstruct the sideburn; and the area of the flap was 2.5 cm×1.0 cm-4.2 cm×3.0 cm. And the superficial temporal artery descending branch perforator flap without hair was used to repair the hair-free area; and the area of the flap was 2.5 cm×1.5 cm-7.5 cm×4.0 cm. The donor sites were sutured directly.ResultsAll flaps survived, and the incisions at the donor and recipient sites healed by first intention. Eleven patients were followed up 6-12 months (mean, 9 months). The incisions were not obvious. The flaps were flat and the color of the flaps were not significantly different from the surrounding skin. The reconstructed sideburns were consistent with the healthy side and the facial appearance was satisfactory. No local tumor recurred during follow-up.ConclusionFor the temporal skin and soft tissue defects involving the sideburn, the superficial temporal artery composite perforator flap can be used to repair subunits with different aesthetic characteristics in sections and has the advantages of operating simply, obtaining satisfied facial appearance, and little effect on the donor site.
OBJECTIVE: With the recognization of the mechanism of wound healing, some topical agents are created and applied in trauma to improve the healing rate of wounds. The main purpose of this study is to investigate the effect of some topical agents on the healing rate of deep second-degree burn wounds. METHODS: One thousand five hundred and sixty-three patients with deep second-degree burn wounds(total burn surface area lt; or = 10%) were involved in this study from January 1982 to December 1999. According to the application time of different treating measures including supplement of Zn, application of growth factors and collagenase, the patients were divided into 3 groups, wound healing rates were compared. RESULTS: Before 1991, none of special topical agents were used, and the healing time of deep second-degree burn wounds was(23.8 +/- 3.5) days. From 1991 to 1996, with the topical application of SD-Ag-Zn, which can provide Zn for cells taking part in wound healing, the healing time of deep second-degree burn wounds was (20.6 +/- 3.2) days, earlier than no special topical agents (P lt; 0.05). From 1997 to 1999, growth factors such as basic fibroblast growth factor(bFGF) and epithelial growth factor (EGF) and collagenases were applied in wound treatment combining with SD-Ag-Zn, wound healing time was (16.2 +/- 2.8) days, earlier than no special topical agents (P lt; 0.01) and simple SD-Ag-Zn application (P lt; 0.05). CONCLUSION: It indicates that the improvement of topical agents can accelerate wound healing speed.
Objective To investigate the effectiveness of autogenous platelet-rich plasma (PRP) gel with acellular xenogeneic dermal matrix in the treatment of deep II degree burns. Methods From January 2007 to December 2009, 30 cases of deep II degree burns were treated. There were 19 males and 11 females with an average age of 42.5 years (range, 32-57 years).The burn area was 10% to 48% of total body surface area. The time from burn to hospitalization was 30 minutes to 8 hours. All patients were treated with tangential excision surgery, one side of the wounds were covered with autogenous PRP gel and acellular xenogeneic dermal matrix (PRP group), the other side of the wounds were covered with acellular xenogeneic dermal matrix only (control group). The heal ing rate, heal ing time, infection condition, and scar formation were observed. Results At 7 days after operation, the infection rate in PRP group (6.7%, 2/30) was significantly lower than that in control group (16.7%, 5/30, P lt; 0.05). The healing times were (18 ± 4) days and (22 ± 4) days respectively in PRP group and control group, showing significant difference (P lt; 0.05). The healing rates at 14 days and 21 days were 75% ± 7% and 88% ± 5% in PRP group, were 62% ± 15% and 73% ± 7% in control group, showing significant difference (P lt; 0.05). RPR group was superior to control group in elasticity, color, appearance, softness, scar formation, and heal ing qual ity. Conclusion Autogenous PRP gel with acellular xenogeneic dermal matrix can accelerate the wound healing of deep II degree burns as well as alleviate the scar proliferation.
Objective To explore the therapeutic effect of recombinant human epidermal growth factor (rhEGF) for burn wounds of degree II in the elderly patients. Methods From February 2003 to October 2008, 80 patientes with burn wounds of degree II were treated and randomly divided into two groups (n=40). In treatment group, there were 24 males and 16 females with an average age of 70 years (60-86 years), including 20 cases of superficial II degree and 20 cases of deep II degree.Burn wounds were caused by flame in 23 cases, by hot l iquid in 16 cases, and by electricity in 1 case. The mean time from injury to hospital ization was (2.87 ± 2.57) hours. The wounds were treated with silver sulfadiazine (SD-Ag) and rhEGF. In control group, there were 18 males and 22 females with an average age of 69 years (61-83 years), including 19 cases of superficial II degree and 21 cases of deep II degree. Burn wounds were caused by flame in 23 cases, by hot l iquid in 14 cases, by electricity in 2 cases, and by chemistry in 1 case. The mean time from injury to hospital ization was (3.39 ± 3.33) hours. The wounds were treated with SD-Ag. The dressing was changed every day until wounds heal ing. There were no significant differences in general data between two groups (P gt; 0.05). Results Wound did not heal in 1 case (deep II degree) of treatment group and in 5 cases (deep II degree) of control group over 40 days and free skin graft was used to repair wound. One case (superficial II degree ) in control group gave up treatment. One case (deep II degree) died of pulmonary infection in treatment group. These cases were excluded and 72 cases were analysed. No other side reactions were observed in teatment group except for flash stabbing pain (4 cases) and pruritus (2 cases). Wound infection occurred in 5 cases of the control group and in 3 cases of the treatment group, and wound healed after symptomatic treatment. The heal ing time of burn wound was (14.30 ± 1.26) days (superficial II degree) and (26.11 ± 2.97) days (deep II degree) in the treatment group, was (16.22 ± 1.40) days (superficial II degree) and (29.13 ± 4.99) days (deep II degree) in control group, showing significant difference between two groups (P lt; 0.05). Conclusion Incombined treatment, rhEGF can promote the heal ing of burn wounds of degree II in the elderly patients.
