Inserting a cannula into a vein

(Deutsches Aerzteblatt International) Patients who are given a local anesthetic before having a venous cannula inserted have a clearly reduced sensation of pain when larger gauge cannulas are used. Compared with intradermal lidocaine infusion, the use of vapocoolant spray has the advantage that the rate of venepuncture failures is lower. This is the conclusion reached by Dirk R ü sch and coauthors from Marburg University based on a randomized controlled trial.
