Document Summary

Objectives: discuss venipuncture, different methods used, site selection, pre peri and post procedural tasks. Supplies needed: 18 - 22 gauge, 18 antecub, easier to adapt to the size of the peripheral vein chosen, verify inventory. If high flo(cid:449) rate (cid:449)ith (cid:271)utterfly: the (cid:374)eedle is o(cid:374) its o(cid:449)(cid:374) a(cid:374)d does(cid:374)"t ha(cid:448)e a (cid:272)atheter over it- can pierce the vessel. Choosing a site: superficial venous anatomy of upper extremity allows many choices. Irritation in the lower veins, long transit time, smaller veins in feet. Low pressure injections: hand injection, should be avoided when power injection technique is used, may result in extravasation and patient injury. Patient monitoring case study: discuss the following with your partner, any peri-procedural considerations, the time between venipuncture and table time, considerations during procedure, post procedural tasks, patient communication highlights, patient care concerns.
