“I suspected colonization, and
MolecuLight i:X guided me to
efficiently target debridement and
topical therapy application to ensure
maximum removal of the bacterial
load and prevent further
- Rose Raizman, RN-EC, MSc
Clinical Synopsis: Clinician used MolecuLight i:X to confirm the presence and location of Pseudomonas aeruginosa in a venous leg ulcer. As seen in Figure 3, the white/cyan color suggests heavy levels of Pseudomonas aeruginosa pre-debridement (the white/cyan color is due to signal oversaturation), which would otherwise be invisible to the unaided eye. The clinician uses this information to guide debridement of bioburdened tissue and re-imaged the wound post-debridement. Figure 4 indicates a reduction in bioburden post-debridement, but not the eradication of Pseudomonas aeruginosa.

|Wound Etiology and Location||• Venous leg ulcer, left-leg|
|Patient Demographics||• Female, 78 years old|
|Patient-Related Challenges||• Home care nurses had stopped using prescribed antimicrobial against clinician orders|
|Patient General Care Paradigm||• Antimicrobial paste
• Local wound care
|Clinician Stated Utility of the MolecuLight i:X||• Visualization of periwound bacteria led to larger cut dressings
• Guided selection of antimicrobial (silver) cream and dressings
Conclusion: The MolecuLight i:X images (Figure 4) provided important evidence that Pseudomonas aeruginosa was still present after debridement, which helped the clinician make the decision at the point of care to select antimicrobial (silver) cream and dressings as well as applying a larger dressing to fully manage the remaining bacterial load. This example shows how the MolecuLight i:X may provide important insights about the location of bacteria so clinicians can target debridement and treat wounds more effectively, compared to the standard of care
