Self-Adjusted Nitrous Oxide: A Feasibility Study in the Setting of Vasectomy

Summary

This study is being done to see if nitrous oxide during vasectomy decreases pain and anxiety, and also assess whether patients have better satisfaction when they control their own level of nitrous oxide during the procedure. If we find that patients experience less pain or anxiety with nitrous oxide, it could be suggested that self-adjusted nitrous oxide (SANO) may be a useful tool for improving experience of care during vasectomy.
