nitrous oxide and Labor Pain

nitrous oxide has been researched along with Labor Pain in 39 studies

Nitrous Oxide: Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.
dinitrogen oxide : A nitrogen oxide consisting of linear unsymmetrical molecules with formula N2O. While it is the most used gaseous anaesthetic in the world, its major commercial use, due to its solubility under pressure in vegetable fats combined with its non-toxicity in low concentrations, is as an aerosol spray propellant and aerating agent for canisters of 'whipped' cream.

Labor Pain: Pain associated with OBSTETRIC LABOR in CHILDBIRTH. It is caused primarily by UTERINE CONTRACTION as well as pressure on the CERVIX; BLADDER; and the GASTROINTESTINAL TRACT. Labor pain mostly occurs in the ABDOMEN; the GROIN; and the BACK.

Trial Outcomes

Mean Anxiety Score Experienced During Version

Anxiety scores will be collected following each version attempt using an 11 point scale (0 being not at all anxious; 10 being extremely anxious), ranging from 0 to 10. Higher scores indicate more anxiety, lower scores indicate less anxiety. If more than one attempt, anxiety scores will be averaged to obtain a single score for the entire procedure. (NCT03502915)
Timeframe: During each version procedure, a total average of up to approximately 30 minutes

Interventionscore on a scale (Mean)
Nitrous Oxide4.696
Oxygen4.253

Mean Pain Score Experienced During Version

Pain scores will be collected following each version attempt using an 11 point scale (with 0 being no pain at all; 10 being worst pain imaginable), ranging from 0 to 10. Higher scores indicate more pain, lower scores indicate less pain. If more than one attempt, pain scores will be averaged to obtain a single score for the entire procedure. (NCT03502915)
Timeframe: During each version procedure, a total average of up to approximately 30 minutes

Mean Post-procedure Pain Score

Pain scores will be collected following completion of the version using an 11 point scale (0 being no pain at all; 10 being worst pain imaginable), ranging from 0 to 10. Higher scores indicate more pain, lower scores indicate less pain. (NCT03502915)
Timeframe: Immediately Post-procedure, within approximately 15 minutes of final version attempt

Mean Post-procedure Patient Satisfaction Score

Satisfaction will be assessed following the procedure using an 11 point scale (0 being not at all satisfied; 10 being extremely satisfied), ranging from 0 to 10. Higher scores indicate more satisfaction, lower scores indicate less satisfaction. (NCT03502915)
Timeframe: Immediately Post-procedure, within approximately 15 minutes of final version attempt

Mean Post-procedure Provider Assessed Level of Difficulty Score

Following the procedure, the obstetric provider performing the procedure will rate the ease of procedure on a 1-10 scale (1 being very easy and 10 being extremely difficult), ranging from 1 to 10. Higher scores indicate more difficulty, lower scores indicate less difficulty. A 10 point scale was used for this outcome, while an 11 point scale was used for the other 4 outcome measures (pain, anxiety, post-procedure pain and satisfaction). (NCT03502915)
Timeframe: Immediately Post-procedure, within approximately 15 minutes of final version attempt
