How to Calculate: Formula & Steps

Computes volume in cubic centimeters (cc), then multiplies by standard ointment density (~1 gram/cc) to estimate ointment usage in grams.

Formula Used:Grams = Wound Area (cm²) × Application Thickness (cm) × Frequency/Day × Days × Density Factor

Step-by-Step Calculation Example

A 5cm × 4cm wound with a nickel-thick (2mm) application once daily for 14 days requires about 56 grams of Santyl.

Common Mistakes to Avoid

Applying the ointment too thick or spreading it onto healthy surrounding skin, which can cause skin irritation.

Practical Use Cases

Clinical prescription estimating
Pharmacy cost authorization calculations

Expert Tips

Protect surrounding healthy skin by applying a barrier ointment (like zinc oxide) before laying down the Santyl debrider.
