A Simple Dressing Technique Following Dermofasciectomy and Full Thickness Skin Grafting of the Fingers in the Treatment of Severe Dupuytren’s Contracture

Dupuytren’s disease with severe finger contractures and recurrent contractures following previous surgery often have extensive skin involvement. In these severe cases, excision of the diseased chord along with the involved skin is a good option to reduce the risk of recurrance. The resulting skin defect can be covered with a full thickness skin graft (FTSG) or a cross finger flap. Cross finger flaps have donor finger morbidity and hence a full thickness graft is usually preferred. The FTSG extending to the midlateral margins on both sides of the finger reduces the risk of joint contracture due to graft shrinkage. Once the FTSG is sutured in place, the standard practice is to compress and secure the graft to its recipient bed with a tie-over dressing and this can be time consuming. We present a simple dressing technique to secure the FTSG without the need for a tie-over dressing.     

敷料更换的不同次数对穿刺引流术后穿刺口感染的影响

目的 研究敷料更换的不同次数对穿刺引流术后穿刺口感染的影响.方法 随机将该院2013年6月—2014年7月收治的100位进行穿刺引流术的患者分为两组,50例为A组,50例为B组. 为A组患者1周更换1次敷料,B组患者1周更换2次敷料. 对两组患者穿刺口感染的情况进行分析比较. 结果 A组患者穿刺口感染的几率显著低于B组(P<0.05),A组患者的病原菌定植率显著低于B组(P<0.05),两组患者导管相关性血流感染率差异无统计学意义(P>0.05). 结论 穿刺引流术后的患者1周更换1次敷料比较合理,既能降低患者术后穿刺口感染的几率,又能降低医护人员的工作量,但要注意在敷料发生松动或者潮湿时也要及时进行更换.

Change in granulation tissue coverage and bacteriological load using Low Cost Negative Pressure Wound Therapy in acute musculoskeletal wounds

BackgroundLow cost Negative Pressure Wound Therapy (NPWT) dressings have been considered as an alternative to traditional daily dressings. There is scanty literature evaluating the change in the percentage area of wound covered by granulation tissue following application of low-cost NPWT. The change in the bacteriological flora following application of low-cost NPWT devices has also not been evaluated.MethodsPatients above the age of 18 years with acute musculoskeletal injuries of <3 weeks duration which underwent a surgical debridement and required subsequent wound coverage were included in the study. Area of the wound and the area covered by the granulation tissue as well as the bacteriological count were measured before and after application of NPWT. A low cost NPWT using wall mounted vacuum device was put on the patient giving a constant negative pressure of 125 mm of Hg for 2 days. The findings before and after application of NPWT were compared and analyzed using Wilcoxin Signed-rank test.Results21 patients with mean age of 35.52±15.075 were included. The pre-NPWT granulation tissue area ranged from 122 mm² to 8483 mm² with a mean of 1648.38 mm² (SD = 1933.866). The post-NPWT granulation tissue area ranged from 234 mm² to 7847 mm² with a mean of 2364.48 mm² (SD = 1857.716). The mean increase in granulation tissue was 716.1 mm².The pre-NPWT wound area ranged from 422 mm² to 10847 mm² with a mean of 4009.62 mm² (SD = 3026.209). The post-NPWT wound area ranged from 326 mm² to 9143 mm² with a mean of 3410.33 mm² (SD = 2636.206). The mean reduction in wound size was 599.29 mm².The pre-NPWT bacteriological count ranged from 3000/ml to 130000000/ml with a mean of 12616761.90/ml (SD = 29664589.37). The post-NPWT bacteriological count ranged from 1000/ml to 380000000/ml with a mean of 26401523.81/ml. The mean increase in bacteriological count was 13784761.91/ml.ConclusionThere was a statistically significant decrease in wound size (p = 0.001) and statistically significant increase in percentage area of granulation tissue coverage (p = 0.000) following low cost NPWT application. However there was no statistically significant increase in bacteriological clearance in these patients.
