HB 1155 Louisiana House · 2026 Regular Session

HEALTH CARE/PROVIDERS: Provides for the use of nitrous oxide by physicians during medical procedures

This bill allows licensed physicians in Louisiana to use nitrous oxide as pain relief during minor office surgeries and similar procedures. It requires the Louisiana State Board of Medical Examiners to create specific safety guidelines for this practice while explicitly prohibiting the board from banning its use in these settings. The legislation directly affects doctors who may now have an additional tool for managing patient pain in outpatient settings, provided they follow the board's rules.
