The basic principle of the suture

(1), to ensure good involution suture wounds or wounds. The suture should be layered, stitched at the anatomical level of the organization, strict organizational level, not to get involved or sewn into other organizations, do not leave residual cavity to prevent the effusion of blood clots and infection. Suture the wound edge distance and the pin spacing must be uniform, so it looks beautiful, but more importantly, consistent and tight suture tension force and Contributions to warrant the leak.
(2), pay attention to the tension of the suture. The ligation suture tightness should be closely connected to the edge of the incision subject of the not too tight, in other words, the wound healing sooner or later, good or bad is not the tightness of fully proportional too tight, too loose can lead to poor healing. Should suture the wound tension, wound such defect is too large, consider metastasis flap or skin graft.
(3), the choice of the suture and the suture needle to be appropriate. Sterile incision or less contaminated wound debridement and disinfection cleaning process can be used silk, wound infection or contamination serious choice of absorbable suture vascular anastomosis should choose the appropriate type of damage the needle.
The classification and commonly used suture suture suture many ways, there is no uniform classification. Press the the tissue involution relationship divided into simple suture, eversion suture, the varus suture three categories; each category by a continuous suture sutures were divided into intermittent and continuous suture two; suture and suture the positional relationship between the organization is divided into horizontal suture, the vertical suture; sometimes is above several cases named. Purse-string suture by suture form is divided into semi-purse the suture, U suture, 8 suture, T suture, Y-shaped suture. There are also special-purpose suture, suture, the intradermal suture and suture hemostasis.
