OB‑GYN asks board to revisit rules after clinic interest in low‑dose nitrous oxide; staff to review office‑based surgery regulations

Dr. Lindsey Turner, an OBGYN from Flowood, told the State Board of Medical Licensure May 22 that low‑dose nitrous oxide — commonly called "laughing gas" — can alleviate anxiety and increase patient tolerance for uncomfortable clinic procedures such as endometrial biopsy, IUD placement and cervical biopsy. She said clinics in most states use patient‑driven low‑dose nitrous oxide systems (she mentioned ProNox as an example) and described the technology as having rapid onset and offset, which allows procedures without long‑acting benzodiazepines that require patients to arrange a driver.

Turner said Mississippi was one of only two states that still restricted nitrous oxide for office procedures as a result of a 2018 board decision that treated 50% nitrous use as elevating the procedure from a level‑1 to a level‑2 office surgery, triggering more stringent equipment and medication requirements. Board members and staff discussed technical and safety considerations; anesthesiologist members reminded the assembly that nitrous oxide cannot be used alone for general anesthesia and that environmental/occupational exposure and correct monitoring must be addressed.

Several board physicians recommended a rules‑level review rather than a one‑off fieldwide exception. Executive Director Ken Cleveland told members the staff could research how other states regulate nitrous oxide, examine competency/monitoring requirements, and bring proposed language to the rules and regulations committee. The board directed staff to undertake a comprehensive review of the office‑based surgery regulations and return recommendations to rules and regs.

The board did not change any rules at the meeting. Members emphasized patient monitoring, avoidance of co‑administration with other respiratory depressants, and a need for written clinic policies if the board later allows nitrous use by rule.
