Randomized Controlled Trial Clinical Trial
Use of inhaled nitrous oxide for minor eyelid surgery: a placebo-controlled study.
Pain from local anaesthetic injection for minor eyelid surgery can often be severe enough to be the most unpleasant part of the procedure. This study was aimed at assessing the efficacy of 50 : 50 N(2)O/O( 2) (Entonox) in relieving such pain. ⋯ Entonox has been used effectively in different specialties for pain relief. However, our study was unable to show this beneficial effect in relieving pain from local anaesthetic injections for minor eyelid surgery.
