Table 2 Species distribution of microorganisms in seroma cultures performed with a conventional method and with aerobic and anaerobic blood culture bottles. Microbiologic findings in 881 seroma samples after primary breast cancer surgery in 199 patients. The present study was part of a double-blind randomized placebo-controlled intervention study that analyzed the effect of a single dose of 80 mg of steroids on seroma formation after mastectomy
