A Pilot Study to Assess Effects of Self-Administered Nitrous Oxide (SANO) on Urodynamic Study (UDS) Parameters

Summary

A urodynamic study (UDS) is a common procedure done to learn more about the cause of urinary symptoms. For some patients, UDS can be associated with anxiety or discomfort. Nitrous oxide (or laughing-gas) is a well-known sedative which is frequently used in dental offices and for pediatric procedures to reduce anxiety and pain. This study is being done to see if giving low-dose (20-50%) nitrous oxide at the time of UDS affects the measurements taken during the procedure, such as how much volume your bladder can hold, and pressures during urination. If the measurements are the same with and without self-administered nitrous oxide (SANO), it could be suggested that nitrous oxide may be a useful way of reducing patient anxiety and pain during UDS.
