Abstract:

Aim:
To assess the effectiveness of the MolecuLight i:X Imaging Device in the management of bacterial load in burns patients.

Method:
30 burns patients were imaged at various points during their treatment (during dressing changes) using the moleculight camera.

Results / Discussion:
30 patients were photographed. 12 did not have bacterial contamination based on their images and swab results. 18 had growth of Staphylococcus aureus, Pseudomonas aeruginosa or other bacteria. These findings were supported by typical signs and symptoms of infection, violet images and microbiology results.

Conclusion:
Using the MolecuLight i:X is similar to using any smart, touchscreen technology.  It utilises an iPod touch display with proprietary MolecuLight image capture software installed.  The device hardware includes two high efficiency violet (405 nm) LEDs and a dual bandpass optical filter placed over the camera sensor, which allows photo and/or video capture of FL signals in real-time. The research has significant implication for improving overall healing because by detecting bacteria, we may be able to prevent it from reaching critical colonisation, infection and sepsis. Early intervention could reduce the likelihood of graft failure, and determining the accurate bacteria will target antibiotic therapy and prevent antibiotic resistance. The Moleculight camera provides guidance for clinicians in regards to the following: highlighting bacteria, identifying the type of bacteria to be treated and pinpointing the location of the colonisation for more accurate swabbing.
