incision of a vein for the removal or withdrawal of blood; called also venesection and venotomy. arterial blood sample phlebotomy in the nursing interventions classification, a nursing intervention defined as obtaining a blood sample from an uncannulated artery to assess oxygen and carbon dioxide levels and acid-base balance.

Sep 4, 2023 · Venous access is gained by either a formal venotomy with a No. 15 scalpel to accommodate a larger IV cannula or by an introducer needle using Seldinger technique. If using a scalpel, place a hemostat behind the mobilized vein to …

Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible. The great saphenous vein is most commonly used.
