Gangrene from finger pricking

Impact of Squeezing Condition to Obtain Sufficient Blood Volume for Self-Monitoring of Blood Glucose Using an Automatic Puncturing and Sampling System

“…However, puncturing should be minimized because patients with diabetes are vulnerable to infection and wound-healing problems. 10,11 To solve the squeezing failure factor, it is possible to add a mechanism to warm the fingers, but patients with diabetes often have peripheral neurological disorders, 12 presenting a risk for burn injury. Therefore, to increase success rates, we changed the squeezing condition by shifting the timing of squeezing and sampling, which were performed simultaneously in the previous experiment.…”

Revascularization Options for Terminal Distal Ischemia

“…Patients with diabetes may need to use a site other than the fingertip (such as the earlobe) for checking blood glucose levels to prevent the onset of digital gangrene. 4 Local care of a finger wound once established follows the usual parameters of wound care. In the author's experience with this group of patients, pharmaceutical management with calcium channel blockers and anticoagulants is usually not helpful.…”

The accuracy and acceptability of performing capillary blood glucose measurements at the earlobe

“…, Dahiya et al . ), or it is clinically contraindicated to obtain a blood sample when intravenous infusion is being given through the hand. Also, as the fingertip is rich in sensory nerves, the pricking procedure can be a painful experience and repeated pricking at the fingertips is highly likely to lead to tissue damage and poor fine sensitivity (Monami et al .…”

“…In current practice, blood samples are often obtained from the fingertip due to its high vascularization and easy accessibility (Dufaitre-patouraux et al 2004). However, in some circumstances, the fingertip is not an appropriate site for lancingfor example, if the fingers are injured or oedematous (Le Floch et al 2008, Dahiya et al 2012, or it is clinically contraindicated to obtain a blood sample when intravenous infusion is being given through the hand. Also, as the fingertip is rich in sensory nerves, the pricking procedure can be a painful experience and repeated pricking at the fingertips is highly likely to lead to tissue damage and poor fine sensitivity (Monami et al 2002, Giannini & Mayr 2004, Anzalone 2008.…”
