Another form of pharmacologic pain relief available for laboring mothers is inhaled nitrous oxide. This is typically a 50/50 mixture of nitrous oxide with air that is an inhaled analgesic and anesthetic. Nitrous oxide has been used for pain management in childbirth since the late 1800s.
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]
Nitrous oxide, as medical gas supply, is an inhaled gas used as pain medication, and is typically administered with 50% oxygen mix. It is often used together with other medications for anesthesia . [ 2 ]
From 1993 to 2016, 30 death certificates in England and Wales mentioned nitrous oxide. Of those, 6 were in the 17-year period from 1993 through 2009, and 24 were in the 7-year period from 2010 through 2016.
The death rate of black women has also continued to climb with a 2020 CDC report showing the maternal death rate at 55.3 deaths per 100,000 live births – 2.9 times the rate for white women. [189] In 2023, a study reported that deaths among Native American women were even higher, at 3.5 times the rate for White women.
The maternal mortality rate in 2022 was 22.3 deaths per 100,000 live births, compared with 32.9 per 100,000 in 2021, according to the new report. ... mortality because it wasn’t nuanced enough ...
The past 60 years have consistently shown considerable racial disparities in pregnancy-related deaths. Between 2011 and 2014, the mortality ratio for different racial populations based on pregnancy-related deaths was as follows: 12.4 deaths per 100,000 live births for white women, 40.0 for black women, and 17.8 for women of other races.

When water-soluble gases such as anesthetic agent N 2 O (nitrous oxide) are breathed in large quantities they can be dissolved in body fluids rapidly. This leads to a temporary increase [ clarification needed ] in both the concentrations and partial pressures of oxygen and carbon dioxide in the alveoli.
