Tissues are replaced to their normal anatomic positions with minimal amount of tension by sutures to prevent tissue devitalization. As tissues are returned to their normal positions, dead space needs to be obliterated by careful suture placement to appose tissue and/or placement of drains to prevent fluid accumulation. Dead space can delay healing and serve as a site for bacterial growth and fluid accumulation. Retraction and dissection of tissue can produce pockets known as dead space. For example, vascular forceps are used to occlude blood vessels when flow is to be reestablished hemostatic forceps, which crush, are applied to vessels through which blood will no longer flow.Īccurate tissue apposition enhances healing and promotes rapid return to normal function. Proper use of surgical instruments minimizes trauma. Electrocoagulation can be used for minor hemorrhage large vessels should be ligated. To avoid excessive tissue damage, only the vessel to be occluded is in contact with the electrode. In using electrocoagulation, a high frequency current is applied to a small area of tissue (the bleeding vessel) and electric energy is converted to heat, resulting in coagulation of tissue and sealing of the vessel. Only the vessel to be occluded should be incorporated in a ligature or clip. Hemostasis is achieved by ligation, pressure, electrocoagulation and avoiding damage to major vessels. Exposed tissue must be protected from drying or contamination.Įffective hemostasis and maintenance of blood supply allows visualization of the surgical field while preserving the total blood volume. Tissues should not be cut or separated without reason and tissue dissection is usually done along fascial planes. Gentle handling of tissues will help minimize postsurgical pain. Gown front is sterile only from waist to shoulder level.Draped tables are sterile only above the table level.Non-sterile persons never reach across a sterile field.All persons who touch sterile articles must be sterile.If in doubt about sterility of item or person, it is not!.All articles must be sterilized before use in procedure.Potential sources of contamination include the team members, the patient, all articles used in the procedure, the surgical room or area, and other personnel entering the surgical area. "Asepsis is a chain which is only as strong as its weakest link." Aseptic technique is required at all times and all team members are responsible for monitoring for breaks in aseptic technique. expeditious performance of the surgical procedure.appropriate use of monitoring equipment.maintenance of sufficient blood supply to tissues.Proper surgical technique is important to prevent wound infection, promote wound healing, and ensure likelihood of a satisfactory outcome to the surgical procedure.
