Efficiency of Hyperbaric Oxygen Therapy Combined with Negative-Pressure Wound Therapy in the Treatment Strategy of Fournier’s Gangrene –A Retrospective Study

Fournier’s gangrene (FG) is a serious, aggressive, and often fatal multi-organism infection that affects the soft tissues of the perineum, rectum, and external genitalia. This study aimed to analyse the treatment’s strategies of FG.

This was a retrospective study of 35 patients with a diagnosis of FG admitted between 2016 and 2021. The diagnosis of FG was established on a clinical basis. Data on patient’s age, sex, comorbidities, laboratory results (C-reactive protein (CRP), white blood cell (WBC), hematocrit (HCT), platelets (PLT), sodium, potassium, creatinine, procalcitonin, international normalized ratio (INR), and gangrene culture), extent of resection, antibiotics used, and hospitalisation time were obtained. The extent of resection was assessed on a scale of 1–5.

The study group consisted of all men (n=35) aged 24–85 (mean, 58) years. In 13/35 (37%) patients, hyperbaric oxygen therapy (HBOT) combined with negative-pressure wound therapy (NPWT) was used as a treatment for wound healing in Fournier’s syndrome (group 1), and in 22/35 (63%) patients, open standard wound care was used (group 2). There were no fatalities in group 1, but four deaths (18%) were noted in group 2. The median extent of resection was 3 in group 1 and 2 in group 2. There was a correlation between the extent of resection and use of HBOT combined with NPWT. The hospitalisation time was much shorter in group 2 (mean, 23 days) than in group 1 (mean, 26 days).

HBOT and NPWT (group 1) showed advanced wound healing with a high efficiency rate. The longer median hospitalisation time in this group may be related to the severity of injury.
