Does Alkalinization of Technetium-99m Sulfur Colloid Reduce Perceived Pain Levels During Non-breast Sentinel Lymphoscintigraphy?
Pain during nuclear medicine breast lymphnode detection procedures has been reported as high
as 8.8/10. Using Sodium Bicarbonate to alkalinize the radio-pharmaceutical injection, pain
can safely be reduced from 6.6/10 to 4.7/10, during breast lymph node detection procedures.
In sites other then the breast, using Bicarbonate to make the injection's pH closer to
natural, attempts to lower the pain levels will be performed.
Hypothesis: The perceived pain level during non breast sentinel lymph node techniques can be
reduced by raising the pH of the injectate (Tc-99m SC) to near the physiologic level of pH
7.40.

Inclusion Criteria:
- Patients presenting for SLN imaging for melanoma or who have had an excisional biopsy
for melanoma of the thorax and appendicular structures;
- Patients scheduled to receive two or more injections of Tc-99m SC for the purpose of
clinical management of melanoma or who have had an excisional biopsy for melanoma of
the thorax and appendicular structures.
