In acute wounds, the microbiological spectrum depends primarily on the cause of the emergence of the wound. 45 Urogenital flora usually includes Eschericia coli, staphylococci, streptococci, diptheroids, lactobacilli, and enterococci. 45 In gastrointestinal tract flora, streptococci, lactobacilli, Bacteroides, and Clostridium species are typically present.

Normal skin flora is usually predominated by Gram-positive organisms, such as staphylococci, micrococci, and diptheroids.

38īefore focusing on the bacterial clearance associated with NPWT, knowledge regarding normal flora and the microbiological spectrum found in acute and chronic wounds is crucial and necessary for the successful management of such cases. 44 Based on these reports, the United States Food and Drug Administration (FDA) has identified bleeding, infection, and retained dressing material as three potentially life-threatening complications of NPWT. 37, 38 Major complications include toxic shock syndrome, 39 bleeding complications, 40 arterial erosion and hemorrhage, 41 empyema, 42 uncontrolled sepsis, 43 and major bleeding complications due to cardiac rupture. Minor complications mostly involve device malfunctions, loss of pressure, and leakage or damage to periwound skin caused by the trac pad. Emergency surgery, unplanned changes in procedures, and high body mass index were identified as risk factors.Ī variety of complications have been reported at the NWPT site. Fifty-four percent of the foreign bodies were left in the abdomen or pelvis, 22% in the vagina, 7.4% in the thorax, and 17% were left in the spinal canal, face, brain, and extremities. Furthermore, 69% of the cases involved sponges, and 31% involved instruments. 36 Although difficult to determine, it was estimated that the risk of retained materials was 1 per 3,000 cases of all surgical interventions. analyzed the risk factors for retained instruments and sponges after surgery in 61 cases. Besides the usual complications ( e.g., prolonged wound healing, infection, or thrombosis) that might occur in every surgical discipline, retained materials pose relatively rare complications however, such complications result in serious consequences for patients.

PICO 7 Single Use Negative Pressure Wound Therapy System VIA™ Negative Pressure Wound Therapy System The development of foams with radiopaque markers by the industry, such as those routinely used in surgical gauze swabs, might also be a useful step to minimize the risk of foam retainment within wounds. At foam removal, all dressing materials should be examined for integrity. The lack of routine documentation of the number, type, and localization of the inserted foam(s) and unplanned surgery with a different surgical team pose risk factors for foam retainment.įuture Directions: Introducing new documentation records for wounds treated with NPWT is recommended. Further imaging methods ( e.g., CT and MRI) also do not help in adequate differential diagnosis. Although the exact incidence remains unknown, initial studies have indicated rates of up to 10% in large collectives being treated by NPWT.Ĭritical Issues: The lack of radiopaque markers does not allow for the visual control of retained foams using plain radiographs. Recent Advances: In the past 15 years, an increasing number of studies have identified this potential problem. Retained foams are among its side effects, and they pose a rare but devastating complication at the site of this therapy, which might be associated with wound-healing complications, infection persistence, repeated surgical revisions, and prolonged antibiotic courses. Significance: Negative pressure wound therapy (NPWT) has become a valuable adjunct in the treatment of acute and chronic wounds in several surgical disciplines.
