The electric burn is a kind of special injury, in which the injured areas are not big, but deep tissues and organs are often injured, resulting in higher rates of mortality and amputation than thermal injury. In the process of management, besides the treatment for systemic and pathologic changes, wound repair is also emphasized for restoration of function. In the past 50 years, ten thousand patients with electric burn were cured in our country, including hundreds of severe electric burn patients with extensive injury. Lots of operative regimes for electric burn were developed, and the scope of experimental research was broadening. As a result, six monographs concerning electric burns were published. However, clinical management of severe electric burn to give a satisfactory result is still difficult, therefore further indepth research is necessary, especially in the field of the use of artificial skin, vessels, nerves, muscular tendon, etc. from gene and tissue engineering to improve quality of wound repair.

OBJECTIVETo evaluate the effect of insular pectoralis major myocutaneous flap on repair of jaw and neck tissue defect as a result of high-voltage electric burn.

METHODSEighteen patients with large area tissue defect in jaw and neck caused by high-voltage electric burn hospitalized from August 2001 to December 2007 were repaired with insular pectoralis major myocutaneous flap. The flaps (from 12 cm x 10 cm to 16 cm x 13 cm) was transplanted in 8 patients after early wound debridement, and in 10 patients on infected wounds.

RESULTSAll flaps survived wells except in 4 patients necrotic area (length 2-5 cm, width 1-2 cm) appeared in the distal wound edge, localized dehiscence of wound edge in 2 cases, which were healed after dressing change or secondary suturing. Patients were followed up from 6 months to 3 years, and the appearance and function were satisfactory.

CONCLUSIONSPectoralis major muscle island myocutaneous flap has the advantage of large tissue mass, with thin and flat muscle belly, and rich blood supply, which is suitable for repair of large deep tissue defect in jaw and neck.

OBJECTIVETo dicuss the application and therapeutic effect of middle-forearm flap based on perforator of ulnar artery for electrical burn wound on the wrist.

METHODSFrom Oct. 2009 to Oct. 2012, 10 cases of electrical burn wounds on the wrist were treated. A line from radialis medial epicondyle of humerus to the interior radialis pisiform bone was connected as flap axis. At the midpoint of the line, Doppler flow imaging meter was used to detect the emerging point of perforator vessel. The flap was designed and harvested. The flap was transferred reversely, with superficial vein retaining which was anastomosed with vein at recipient sites in 3 cases. The wounds in the donor sites were closed directly in 2 cases, and with skin graft in 8 cases.

RESULTSAll the 10 flaps survived completely. 7 cases without vein anastomosis underwent obvious flap edema during 2-4 days postoperatively, which resovled 1 week later. Sub-flap tissue necrosis and infection happened in 2 cases, which healed after dressing and drainage. Patients were followed up for 3-36 months with satisfactory results.

CONCLUSIONSThe middle-forearm flap based on perforator of ulnar artery has a stable and reliable blood supply. It offers a new choice for the electric burn wound on the wrist, especially at the ulnar side.

OBJECTIVETo analyze the management of high-voltage electrical burn injury of the scalp in our hospital.

METHODSThis study involved 10 patients who suffered from high-voltage electrical burn injury of the scalp. Scalp reconstruction was done by different modalities according to the size and location of the defect.

RESULTSComplete flap viability was achieved in all the cases. We had one case of gapped wound which was managed only by dressing. Widening of the scar was found in 2 cases.

CONCLUSIONRotation, advancement and transposition scalp flaps are used for reconstructing scalp defects caused by electrical burn. The choice of ideal flaps for reconstruction depends upon the size and site of scalp defect.

OBJECTIVETo explore the method for repairing circumferential wound in the wrist region due to high-voltage electrical burn.

METHODSSix patients with circumferential wound in the wrist region after high-voltage electrical burn were admitted to our hospital from January 2009 to December 2011. After debridement, wounds in the wrist were repaired with combined abdominal axial pattern flaps. The wound of wrist on the flexor aspect was repaired with paraumbilical flap carrying a portion of rectus abdominis that filled the wound cavity of the wrist on the flexor aspect. The wound of wrist on the dorsal aspect was repaired with lower abdominal flap. Pedicle division was performed 4 - 5 weeks post surgery. Some donor sites were sutured directly, and the others were closed by skin grafting after the suture of anterior sheath.

RESULTSThree flaps survived. Liquefaction necrosis of tissue was observed under two flaps, and they were healed after debridement. Radial artery embolism of wrist occurred in one flap when pedicle division was performed 5 weeks post surgery, and it was healed by a transplantation of a segment of the great saphenous vein to reconstruct radial artery right after debridement. Patients were followed up for 6 - 12 months, and satisfactory appearance and function of the flaps were observed.

CONCLUSIONSIt is a feasible option to repair circumferential wound in the wrist region due to high-voltage electrical burn by using paraumbilical flap carrying a portion of rectus abdominis muscle combined with lower abdominal flap.

OBJECTIVETo explore the methods and effects of repair of occipital and nuchal wounds with inferior trapezius myocutaneous flap after deep electrical bum.

METHODSTwelve patients with high-voltage electrical burn in occipital and nuchal regions were hospitalized to our ward from March 2003 to September 2007. They were repaired with improved inferior trapezius myocutaneous flaps after debridement. Flaps were of two types: (1) blood supply from cutaneous and perforator branches of the original segment of the superficial descending branch of transverse cervical artery. (2) combined blood supply from both superficial and deep descending branches of transverse cervical artery C, i.e., dorsal scapular artery). All flaps carried segmental and limited trapezius muscle cuff surrounding the vascular pedicle of the flap similar to a perforator flap.

RESULTSFlaps survived completely primarily in eight cases. In two patients, infection developed in flaps adjacent to wounds with lignification; they healed after dress change. Necrosis appeared in distal end of flap (one case), it healed after re-operation. One patient with surviving flaps died of sepsis and multiple organ failure 21 days after operation. The flaps which survived were not swollen ; the donor sites at scapular region looked normal without pterygoid or pendulous scapula deformities.

CONCLUSIONInferior trapezius myocutaneous flaps can be used to repair occipital and nuchal wounds, with the advantages of constant blood vessels, reliable blood supply, convenience for application.

A 55-year-old male patient suffered from severe high-voltage electric burn with an area of 20%TBSA full-thickness injury. The injury involved the distal end of left upper limb, right trunk, and whole abdominal wall. Fracture of the 7th-10th ribs was found in the right side of chest, with perforation of abdominal cavity, and bilateral pleural effusion was found. Part of the small intestine was necrotic and exposed. At the early stage, xeno-acellular dermal matrix was grafted after debridement of abdominal wound; peritoneal lavage was performed; negative pressure drainage was performed in orificium fistula of intestine for promoting the adhesion between perforated intestine and abdominal scar. Two orificium fistulas formed after closure of abdominal granulation wound by autologous skin grafting. Eschar of chest wall and denatured ribs were retained. The risk of infection of thoracic cavity was decreased by promoting the adhesion between lung tissue and chest wall. During the treatment, the patient was diagnosed with Henoch-Schonlein purpura nephritis by renal biopsy, with the symptoms of purpura in the lower limbs, heavy proteinuria, severe hypoalbuminemia, edema, etc. After control of kidney damage by immunosuppressive treatment instead of glucocorticoid, alleviation of the levels of proteinuria and blood albumin, free latissimus dorsi myocutaneous flap was excised to repair chest wall, and free skin graft was excised to repair intestinal fistula. After all the wounds were successfully covered, the patient was treated with glucocorticoid combined with immunosuppressants for more than 1 year. The patient was followed up for 3 years, and his renal function was completely recovered with satisfactory clinical outcome.
