Objective To explore the clinical efficacy of ebridement and suturing combined with double vacuum sealing drainage (VSD) technology for the treatment of pressure ulcer. Methods Totally 32 patients of pressure ulcer (from July 2011 to October 2015) re-ceived debridement and suturing after infection control. Then F14 silicone ventricular drainage tube was placed in the wound for drainage while VSD was placed outside the wound. Both tubes inside and outside wound were connected to the central vacuum (20~40 kPa). Three days after the drainage,F14 silicone ventricular drainage tube was removed,and VSD material outside wound was replaced to continuous vacu-um treatment for another 3 to 4 days. Results All of 32 cases were healed up without hematoma,dead space and flap margin necrosis,inclu-ding 4 cases of poor healing,which were healed after active dressing. Conclusion Small area of the pressure ulcer can be closed up by de-bridement and suturing combined with double VSD technology,which is a simple operation with little injury and high clinical application value.

Objective To evaluate the cosmetic outcomes of nasal aesthetic sub-unit principle. Methods From May 2007 to March 2015,19 patients with traumatic soft tissue defects of nose had a Single-stage reconstruction with suitable reconstructive method. Full-thick-ness skin transplantation was performed in 1 case,forehead nasal flap in 1 case,bilobed flaps in 2 cases,nasolabial flaps in 9 cases,a folded nasolabial flap in 2 cases,free auricular composite flap in 1 case,the temporal flap pedicled with the orbicular oculi muscle in 3 cases. All pa-tients were followed up for 5~27 months,evaluation items were recorded and analyzed. Results Skin transplantation and local flap were all survived. But 1 case with nasolabial flap infected was healing by second intention,the rest were primary healing,free auricular composite flap was gloomy,and it became normal 5 months after operation. The radian and the curve of the folded nasolabial flap to repair the nasal alar area were slightly poor. Condusion Good aesthetic effets come from nasal aesthetic sub-unit principle in Single-stage soft tissue reconstruction of a traumatic nasal defects.

Objective: To explore the clinical effect of cotton pads under stitches when intradermal traction with sutures is used to repair of chronic wounds. Methods: From January 2009 to August 2016, 21 patients with 31 wounds were treated by continuous intradermal traction. Wound edges were sutured with 2-0 silk thread in horizontal mattress fashion, but not tied. Then small cotton pads were put under stitches to protect the skin around the wound. After that, the sutures on both sides of the wound edges were pulled to the center of the wound with a certain force. And the wound was sutured finally when the skin on both sides of the wound was closed enough. Results: All of 31 wounds healed without necrosis of the skin margin and 5 cases of lacerated wound caused by silk thread healed after dressing change. The healing time was (43.24±11.46) days, and there was scarcely hypertrophic scar at the stitches. This method was compared with the previous method of protecting stitches with silicone tubes( referring to past data). There was no significant difference in the healing time between the two methods (P=0.119), and less laceration occurred under the stitches with cotton pads (P=0.046). Conclusions It is a commendable method for treating chronic wounds to put cotton pads under the stitches while tracting the wound edges with sutures. It can effectively cushion the cutting force of the silk thread, protect the traction point and facilitate the replacement of the pads.
