A Randomized, Crossover Comparison of Injected Buffered Lidocaine, Lidocaine Cream, and No Analgesia for Peripheral Intravenous Cannula Insertion
Annals of Emergency Medicine, 08/05/09

McNaughton C et al. – In adult health care providers, pain and anxiety associated with peripheral IV insertion is significantly reduced by using topical lidocaine cream or injected, buffered lidocaine. Injected, buffered lidocaine reduces IV insertion pain more than lidocaine cream, without affecting success. Adults desire the use of local anesthetic techniques for IV insertion for themselves and for their patients.

For many of our patients in the ED, IV access is a significant source of pain and anxiety. In our study using healthy volunteers (medical students and nurses participating in PIV training), we were able to show that something as simple as using injected, buffered lidocaine can significantly decrease both pain and anxiety associated with IV placement. And despite requiring a "second stick," the vast majority of participants preferred the injected, buffered lidocaine--for themselves and for future use in their patients.
