New wound swabbing technique detects more bacteria
A new technique for swabbing wounds has proven to be more effective at detecting bacteria than other swabbing methods.
The newly established Essen Rotary swabbing technique only takes a few more seconds to perform than traditional techniques and increases the likelihood that clinicians will find an accurate bacteria count. The new technique investigates a larger surface area of the wound, which is beneficial for detecting Methicillin-resistant Staphylococcus aureus (MRSA).
The Levine system, which is currently the gold standard in wound swabbing, is useful when performed correctly, but is not always an easy task and can be less representative of the actual bacteria present.
'The disadvantage of this method is the fact that it will only be representative if the swab is taken exactly over the infected area,' the study reports. 'Furthermore, it is possible to get false-negative results if too little wound fluid is collected. If the wound is too scabbed, necrotic or massively fibrinous, a prior wound cleansing is necessary to receive a representative result.'
