RESUMO
BACKGROUND: Sternal wound infections are a rare but life-threatening complication of cardiothoracic surgery. Prior literature has supported the use of negative pressure wound therapy to decrease sternal wound infections and promote healing. This study sought to determine whether closed incision negative pressure therapy reduced wound infection and improved outcomes in cardiothoracic surgery. METHODS: A retrospective cohort study was performed including all adult patients who underwent nontraumatic cardiothoracic surgery at a single institution between 2016 and 2018 (n = 1199). Patient characteristics, clinical variables, and surgical outcomes were compared between those who did and did not receive incisional negative pressure wound therapy intraoperatively. Multivariable logistic regression analysis determined factors predictive or protective of the development of complications. RESULTS: Incisional negative pressure wound therapy was used in 58.9% of patients. Patients who received this therapy were older with statistically higher rates of hyperlipidemia, statin, and antihypertensive use. The use of negative pressure wound therapy was found to significantly reduce rates of both wound infection (3.0% vs 6.3%, P = 0.01) and readmission for wound infection (0.7% vs 2.6%, P = 0.01). After controlling for confounding variables, negative pressure wound therapy was found to be a protective factor of surgical wound infection (odds ratio, 0.497; 95% confidence interval, 0.262-0.945). CONCLUSIONS: In the largest population studied to date, this study supported the expanded use of negative pressure therapy on sternal wound incisions to decrease infection rates.

Tissue expanders are known adjuncts in ventral hernia repair, used in a staged approach where tissue closure or coverage of the defect is preferred but inadequate. Placement of tissue expanders in the correct tissue plane can be difficult, especially in thin patients or with loss of domain. This case series describes a technique in which tissue expander placement is facilitated by ultrasound-guided hydro-dissection, following the placement of a transversus abdominis plane (TAP) block. In short, after induction of anesthesia, the same needle used for the ultrasound-guided TAP block can be repositioned by the anesthesiologist to instill tumescent solution into the fascial plane between the internal and external oblique muscles. This allows for identification of the fascial planes in the ensuing operation. Our technique may prove to be an alternative tool in the placement of tissue expanders for ventral hernia repair, or in other procedures requiring device placement.
RESUMO
Periocular necrotizing fasciitis is a rare, but potentially blinding, or even fatal disease. The authors report a case of a 44-year-old man who presented with quiescent bilateral periocular and facial necrotizing fasciitis. The patient was treated with antibiotics and surgical debridement, followed by negative-pressure wound therapy (NPWT), until the wound bed was thought to be healthy enough to support bilateral upper eyelid full-thickness skin grafts. NPWT appeared to decrease local edema; speed reperfusion and granulation tissue formation; and served to stabilize the skin grafts against the wound bed, while not causing any ocular complications. NPWT can be a safe and effective adjunct treatment for periocular necrotizing fasciitis.
