Summary

In this study, the investigators seek to evaluate a novel tissue-cooling device for pain management during needle sticks and /or blood draw on the fingertips.

Detailed description

Patient compliance with laboratory testing is one of the most underrecognized challenges in developing a treatment plan for acute and chronically ill patients. The ability to offer alternatives to standard venipuncture blood draws would greatly increase a laboratory's ability to provide testing to patients and health care providers.The fingerstick blood draw has been used as an alternative. Aiming a less painful, potentially easier alternative we devised a novel that can be applied distally on the digit prior to the blood collection procedure and may provide analgesia through a liquid coolant that is run through tubes in the device to safely cool tissue to achieve numbing. We hypothesize that this device will safely and effectively reduce the pain associated with the fingertip pricks and increase the amount of capillary blood collected. Multiple punctures with a large lancet were a frequent cause of discomfort among patients.With this new device the discomfort will be reduced by its application followed by the numbness of the finger. The investigators plan to have 12 patients to complete the study. Subjects must be equal to greater than 18 years old and younger than 60 years older and may be any gender or Fitzpatrick skin type.
