Pressure ulcer surgery SSI risk factors
surgical site infection
Aims : The most common postoperative complication when treating a pressure ulcer with a flap or primary closure is early wound dehiscence. In this study, we aimed to investigate the cause of early wound dehiscence and its associated risk factors. Early wound dehiscence was defined as the wound dehiscence within the post operation period where no weight or tension is applied to the wound. Methods : We conducted a retrospective study of 40 patients with pressure ulcers (69 sites). We calculated the significant difference in the incidence of wound dehiscence between the groups for the following 15 factors : age, obesity, emaciation, diabetes mellitus, smoking, ulcer site, musculocutaneous flap, methicillin-resistant Staphylococcus aureus, presence of two or more types of bacteria, albumin level, C-reactive protein level, white blood cell count, hemoglobin level, operative time, and ulcer size. Results : Bacteria were detected in all wounds with early dehiscence, which was found in 28 (40.6%) of the 69 cases. C-reactive protein level, albumin level, musculocutaneous flap, and operative time were found to be risk factors for early wound dehiscence using the χ2-test and t-test. (P = 0.011, 0.045, 0.018, and 0.003, respectively). Conclusion : The cause of dehiscence was considered to be surgical site infection. C-reactive protein level, albumin level, musculocutaneous flap, and operative time may be risk factors of the occurrence of early wound dehiscence.
