Maggots may trump scalpels when it comes to cleaning large wounds that won't heal easily, such as those seen in diabetics, according to French researchers.
allow such wounds to heal, doctors usually remove infected or dead
tissue with scalpels or enzymes, a process they call debridement. But
that method is time-consuming and doesn't always work. Studies have suggested maggots might
be helpful, potentially offering antibacterial and healing benefits in
addition to keeping the wound clean - although not all researchers are
convinced insects are the way to go.
new study was carried out in patients with so-called venous ulcers on
their legs. During a two-week hospital stay, they were randomly assigned
to either maggot therapy or traditional wound cleaning with a scalpel,
with just over 50 patients in each group. Both groups of patients were
blindfolded so they wouldn't know which treatment they received.
sterile creepy-crawlies, of the species Lucilia sericata, came in
little bags that were placed over the wounds twice a week. Maggots
secrete substances into the wounds that liquefy dead tissue and then
they ingest the material to further degrade it in their guts.
was no difference in pain or crawling sensations between the two
groups, according to Dr Anne Dompmartin of Centre Hospitalier Universitaire de Caen and colleagues. Their findings appear in the
Archives of Dermatology.
