Negative pressure wound therapy with instillation (NPWTi) has the dual function of negative pressure sealing drainage and irrigation, which overcomes the disadvantages of NPWT, such as tube obstruction, inability to apply topical medicine, and poor anti-infection ability. NPWTi has been researched extensively and widely used in various types of wounds, and certain effects have been achieved. A series of parameters for NPWTi have not been unified at present, including the flushing fluid option, flushing mode, and treatment period. This paper reviews the research progress of these parameters for NPWTi and their application in the treatment of orthopaedic wounds.instillation, negative pressure wound therapy, orthopaedic wounds, treatment parameters
Key Messages• NPWTi has the dual function of negative pressure sealing drainage and irrigation • setting of treatment parameters for NPWTi has not been unified yet: further research studies are required • although there are multiple choices of instillation solutions, normal saline is recommended as the first choice; the recommended setting is the intermittent instillation mode and À125 to 150 mmHg, the duration time depends on the type of wound • NPWTi has been widely used in all kinds of wounds in orthopaedics, such as acute or chronic infected wounds, osteomyelitis, soft tissue injuries, and surgical wound management
