Objectives The study was to evaluate pain perceived by patients undergoing 99mTc filtered Sulfur Colloid Breast Lymphoscintigraphy administration with and without the use of lidocaine. Patients were asked to rate their pain on the universal pain assessment tool of 0 -10, with 10 being the greatest, after the 99mTc Sulfur Colloid breast lymphoscintigraphy injection. Patients were randomly selected for lidocaine use for this study.
Methods Three injections were administered into the superior, lateral and inferior retro-areolar area of the breast. Each administration was by a 3cc syringe attached with a sterile 25 gauge, 1.5-inch long needle, containing 0.150 mCi of filtered 99mTc filtered Sulfur Colloid aliquoted to 1.5 ml with normal saline. 13mg of lidocaine in 0.7ml was added to each of the 99mTc filtered Sulfur Colloid syringe for patients undergoing lymphoscintigraphy procedure with lidocaine. Patients were asked to rated their pain of the injection on the universal pain assessment tool.
Results 127 patients were administrated with lidocaine and 45 without lidocaine. The average pain perceived by the patients from the lidocaine and non-lodocaine 5.5 +/- 2 and 5.99 +/-2.9 respectively.
Conclusions The average pain for the lidocaine administration for both groups was nearly the same. Pain assessment by patient could be from the needle puncture, or hydrostatic pressure in the breast. Difference in the pain perceived may also be contributed from the technique of administration.
