Changing the Buffer in Buffered Lidocaine

This study assessed how lidocaine buffered with bicarbonate compares with lidocaine buffered with saline in minimizing pain with lidocaine injection. Sixty patients received the buffered lidocaine before having a peripherally inserted central catheter inserted. Thirty patients received lidocaine buffered with bicarbonate and 30 patients received lidocaine buffered with saline. Pain and vasoconstriction were the 2 outcomes monitored during the project. Although the trial was only 2 wk due to the urgency of the rollout, the pilot was able to offer clinicians the opportunity to compare the 2 products. The saline-buffered lidocaine provided comparable pain relief compared with the lidocaine buffered with bicarbonate. The clinicians also measured the amount of vasoconstriction caused by the 2 products with similar outcomes.
