RT Journal Article SR Electronic T1 Cannulation of Small Veins Another Approach JF Regional Anesthesia: The Journal of Neural Blockade in Obstetrics, Surgery, & Pain Control JO Reg Anesth Pain Med FD BMJ Publishing Group Ltd SP 133 OP 134 DO 10.1136/rapm-00115550-198308030-00015 VO 8 IS 3 A1 Desai, Sukumar P. YR 1983 UL http://rapm.bmj.com/content/8/3/133.abstract AB A technique to simplify cannulation of small, poorly visible veins is described. This technique using an Esmarch's bandage appears to facilitate venous cannulation by increasing the caliber of the vessel and the length over which it is visible. Furthermore, the vein is palpated more readily, again, simplifying cannulation. Should cannulation be unsuccessful, however, it would be wise to release the Esmarch's bandage as soon as possible to prevent the formation of a large subcutaneous hematoma.
