Nitrous oxide is a gaseous mixture harmless to inhale, ready for use, consisting of 50% oxygen and 50% nitrous oxide. Spreads rapidly in the blood, does not bind to hemoglobin, is not metabolized but is cleared from the lungs, and has a low accumulation in tissues and lipids. It’s an alternative epidural to reduce the pain of childbirth. The gas inhaled during labor allows ease the pain of contractions and to tackle the birth with less anxiety. It was recently introduced in some Italian hospitals while in Anglo is already in use for some time.
WHY USING THE NITROUS OXIDE?
The mixture nitrous oxide and oxygen (LIVOPAN®) is used during the delivery of more than a century for the treatment of pain. In many countries it is currently the most widely used in obstetrics inhaled medication during labor:
• In the UK, 50-60% of women giving birth has used since the early 50

The LIVOPAN® is suitable for women seeking a more soft and non-invasive management of labor pain, preserving the natural character of the labor and delivery.

It has a control valve that delivers gas only in the moment that woman inhales and gathers at other times. It’s therefore the mother to determine when it needs to relieve pain and inhale the analgesic, managing in a completely autonomous administration of the drug.
The exhaled air is then channeled through a slit placed around the mask and then made to flow through a system of gas-evacuation of the room, so that there is no dispersion in the environment.
In this way, its use is safe for all operators who assist the woman in labor.
HOW DOES THE GAS?
LIVOPAN® is generally used towards the end of the first stage of labor, when the contraction become stronger and the pain increases.

For the safety of the mother is important that the drug is self-administered by a mask is not fixed to the face in order to prevent any-sedation. Inhalation should commence approximately 30 seconds before the contraction so that the peak of the analgesic effect coincides with the peak intensity of the contraction, and then with the apex of pain sensation.
