The most commonly used local anaesthetic for local infiltration is lidocaine. It is generally regarded as safe and effective. It is used to provide local anaesthesia prior to laceration repair or other unpleasant procedures such as lumbar puncture. The pain associated with a lidocaine injection as a local anaesthetic is a disadvantage. Several approaches for reducing injection discomfort have been researched. Lidocaine buffering to a neutral pH is thought to help reduce injection pain. Buffering has no effect on the anaesthetic power of lidocaine, and the resulting solution is stable.
