Protocol

Stretch the skin slightly

• to tighten the subcutaneous tissues
• to reveal areas of intralesional «breakdown»
• to highlight undermining
• to accentuate defects and tissue loss

Gently insert the needle

• Inject the liquid by withdrawing the needle, allowing the liquid to flow out
• Leave the liquid in contact with the wound*
• Continue from top to bottom towards the residual wound cavities
• Dry only the blood clots
• Meticulously mark the injection points that create pain

Mapping the most fragile tissue sections

*As an example, local anaesthetic flush reduces p.o. pain but also haematoma formation. Nisar A et al. Eur J Vasc Endovasc Surg, 2006. 31(3):325-331
