Continuous irrigation and suction for septic arthritis

Surgical treatment of septic arthritis with continuous irrigation and aspiration of septic arthritis. Bone and joint infections are one of the major diseases leading to limb dysfunction, especially for children in growth and development, both treatment and prognosis show considerable difficulties. Bone and joint infections mainly include osteomyelitis, septic arthritis, and bone and joint tuberculosis. Treatment of diseases: acute septic arthritis Indication Continuous irrigation and aspiration of septic arthritis are suitable for the treatment of septic arthritis of the extremities such as the hips, knees, and shoulder joints, and if the joint aspiration fluid is turbid or purulent, surgery should be performed immediately. It can not only reduce and prevent secondary joint infection caused by repeated joint puncture, but also effectively drain pus, reduce the dissolution and destruction of articular cartilage, and reduce intra-articular pressure, relieve pain and reduce stress Increased complications such as pathological dislocation of the hip and avascular necrosis of the femoral head. The knee joint is taken as an example to describe the operation. Surgical procedure 1. Determine the flushing and suction tube inlet Marked by the tibia, they are used as entrances and exits on the upper and lower sides of the tibia, respectively, and are marked with methylene blue. 2. Joint cavity cannula At the predetermined entrance, use a sharp knife to make a small incision in the skin, pierce the trocar from the incision, or obliquely under the humerus or into the joint cavity from one side. After the surgeon fixes the trocar, the needle of the trocar is pulled out, and the pus is discharged. The pus was collected for smear examination, bacterial culture and drug sensitivity test. Then, the silicone tube is sent from the trocar into the knee joint, and the direction and depth of the trocar and the silicone tube are adjusted. After seeing a large amount of pus flowing out, the trocar is pulled out and the silicone tube is retained in the joint cavity. The silk tube was sutured and fixed with a silk thread. Insert another silicone tube into the joint cavity at the exit using the above method. Generally, the silicone tube on the upper side of the tibia is used as the irrigation tube, and the lower side of the tibia is the suction tube.
