RESUMO
Objective: To investigate the application effects of self-made simple vacuum sealing drainage (VSD) device in the postoperative treatment of sural neurocutaneous flap transplantation in the foot and ankle. Methods: From January 2017 to January 2019, 36 patients with foot and ankle skin defects and bone exposure admitted to People's Hospital of Xinjiang Uygur Autonomous Region met the inclusion criteria, and a retrospective cohort study was conducted. According to the bandaging method of the operative area, simple negative pressure group and antibacterial dressing group were both allocated with 18 patients, with 12 males and 6 females in the former group, 14 males and 4 females in the latter group, aged (41.6±2.8) and (42.3±2.6) years, respectively. Patients in the two groups all received sural neurocutaneous flap transplantation. Patients in antibacterial dressing group received nano silver antibacterial dressing change in the operative area, and the dressing was changed once every 3 days. In simple negative pressure group, the operative area was sealed with a simple VSD device made of gauze, silicone sputum suction tube with holes cut out, and biological permeable membrane, etc., which was connected with the wall central negative pressure suction system for continuous VSD treatment of -40.0 to -16.6 kPa. The negative pressure material was changed once every 5 days. The number of dressing change, the pain score evaluated by Numeric Rating Scale during each dressing change, the cost of dressing change, and the degree of flap swelling evaluated on the 3rd and 5th day after surgery were recorded, and the flap survival was observed. Data were statistically analyzed with independent sample t test, Wilcoxon rank sum test, and chi-square test. Results: The number of dressing change of patients in simple negative pressure group was (3.4±0.5) times, which was significantly less than (7.0±0.8) times in antibacterial dressing group (t=15.338, P<0.01). The pain score during dressing change of patients in simple negative pressure group was (4.3±0.8) points, which was significantly lower than (6.8±0.7) points in antibacterial dressing group (t=10.168, P<0.01). The cost of dressing change of patients was similar between the two groups. On the 3rd and 5th day after surgery, the degrees of flap swelling of patients in simple negative pressure group were significantly superior to those in antibacterial dressing group (Z=4.448, 2.395, P<0.05 or P<0.01). The flap survival of patients in simple negative pressure group was significantly superior to that in antibacterial dressing group (χ(2)=4.500, P<0.05). Conclusions: Compared with the traditional dressing bandage, the self-made simple VSD device used after sural neurocutaneous flap transplantation can reduce the frequency of dressing change, relieve the pain of dressing change and the swelling of flap, and promote the flap survival, which is worth popularizing and applying in clinic.

December 22, 2018, a pair of female baby twins aged 2 years with severe burns at the same time were transferred from the primary hospital to the People's Hospital of Xinjiang Uygur Autonomous Region on day 17 post burn. Physical examination on admission showed that both of them had severe burns on head, face, left upper limb, foot, etc. The blood preparations were difficult for them due to their rare blood types, with the elder sister of type B blood combined with Rh D mutant and the younger sister of type B combined with Rh negative blood. The total area of burn of the younger sister was 15% total body surface area (TBSA), with full-thickness burns with tendon and bone exposure in left ear and most of the ear auricle fallen off. The younger sister was treated with anti-infection, anti-shock by fluid infusion, and nutritional support. Split-thickness skin graft on left thigh was harvested to repair wound on left upper limb, and thin medium-thickness skin graft was harvested from right thigh in different operations to repair wounds on head and face, and thin medium-thickness skin graft from right thigh with area of 3 cm×1 cm was reserved. The total area of burn of the elder sister was 22% TBSA, combined with inhalation injury and severe lung infection after tracheotomy, and the condition was critical. After admission to the hospital, anti-infection, anti-shock by fluid infusion, nutritional support, atomization, and eliminating phlegm treatment were performed. After the general condition was basically stable and blood preparation was sufficient, thin medium-thickness skin grafts were harvested from left thigh to repair wounds on head, face, and left upper limb, and the reserved thin medium-thickness skin graft from right thigh of the younger sister was transferred to the posterior ear wound of the elder sister. The skin grafts survived after operation with expansion showing no difference from autogenous skin. The elder sister and the younger sister were discharged from the hospital on the 24 and 21 day of hospitalization respectively. During follow-up of 6 months, the effect of the operation was good.

Objective: To explore the risk factors of diabetic foot ulcer (DFU) in diabetic patients of Uyghur nationality and Han nationality in the Xinjiang Uygur Autonomous Region. Methods: Clinical data of 640 diabetic patients admitted to our ward from January 2015 to November 2016, conforming to the study criteria, were retrospectively analyzed. Patients were divided into DFU group (n=403) and non-DFU group (n=237) according to whether DFU occurred or not. The data of gender, age, nationality, body mass index (BMI), smoking, drinking, binge eating, triglyceride (TG), total cholesterol (TC), and high-density lipoprotein (HDL) of patients between two groups were compared with chi-square test and t test. Indexes with statistically significant differences between two groups were selected, and they were processed with non-conditional multivariate logistic regression analysis to screen the independent risk factors of DFU. The possible risk factors of DFU of patients of Uyghur nationality and Han nationality were further processed with non-conditional multivariate logistic regression analysis respectively to screen the independent risk factors of DFU of patients of Uyghur nationality and Han nationality. Results: (1) There were no statistically significant differences in gender, age, TC, and HDL of patients between two groups (with χ(2)=0.149, t values respectively 1.163, 1.033, and 1.026, P values above 0.05). There were statistically significant differences in nationality, BMI, smoking, drinking, binge eating, and TG of patients between two groups (with χ(2) values from 4.778 to 13.694, t values respectively 4.703 and 4.237, P<0.05 or P<0.01). (2) Nationality, BMI, smoking, drinking, binge eating, and TG were the independent risk factors of DFU(with odds ratios respectively 1.488, 1.527, 1.736, 1.738, 1.382, and 1.648, 95% confidence intervals respectively 1.315-3.175, 1.488-4.393, 1.834-4.675, 1.474-2.695, 1.342-4.678, and 1.105-6.747, P values below 0.05). (3) Smoking, drinking, binge eating, and TG were the independent risk factors of DFU in diabetic patients of Uyghur nationality (with odds ratios respectively 1.673, 1.387, 1.328, and 1.486, 95% confidence intervals respectively 1.384-1.765, 1.414-1.659, 1.423-1.687, and 1.150-1.670, P values below 0.05). BMI, smoking, and drinking were the independent risk factors of DFU in diabetic patients of Han nationality (with odds ratios respectively 2.442, 1.604, and 1.251, 95% confidence intervals respectively 2.223-2.699, 1.268-2.028, and 1.164-1.344, P<0.05 or P<0.01). Conclusions: Smoking, drinking, binge eating, and TG were the independent risk factors of DFU in diabetic patients of Uyghur nationality. BMI, smoking, and drinking were the independent risk factors of DFU in diabetic patients of Han nationality.
