New research on wounds that suggests we can decrease our reliance on antibiotics if we merely clean and care for wounds more carefully! –
Researchers originally set out to compare the efficacy of two antibiotics commonly used to treat staph skin infections, randomly giving 191 children either cephalexin, a classic anti-staph antibiotic known to work against the most common strains of the bacterium but not MRSA, or clindamycin, known to work better against the resistant strains. Much to the researchers’ surprise, they said, drug choice didn’t matter: 95 percent of the children in the study recovered completely within a week, regardless of which antibiotic they got.
The finding led the research team to conclude that proper wound care, not antibiotics, may have been the key to healing.
“The good news is that no matter which antibiotic we gave, nearly all skin infections cleared up fully within a week,” says study lead investigator Aaron Chen, M.D., an emergency physician at Hopkins Children’s. “The better news might be that good low-tech wound care, cleaning, draining and keeping the infected area clean, is what truly makes the difference between rapid healing and persistent infection.”
Chen says that proper wound care has always been the cornerstone of skin infection treatment but, the researchers say, in recent years more physicians have started prescribing antibiotics preemptively.
Although the Johns Hopkins investigators stop short of advocating against prescribing antibiotics for uncomplicated MRSA skin infections, they call for studies that directly measure the benefit — if any — of drug therapy versus proper wound care. The best study, they say, would compare patients receiving placebo with those on antibiotics, along with proper wound cleaning, draining and dressing.
