Medical applications

Medical nitrous oxide is a colorless, odourless, sweet-tasting anesthetic that is used as sedative and analgesic. Commonly referred to as laughing gas, nitrous oxide is used in surgery and dentistry for its pain blocking and reducing effects. 

Medical nitrous oxide is used in adults and children for:

  • General anaesthesia – usually as an adjuvant to other volatile or intravenous anaesthetics
  • Pain relief – employed with oxygen for analgesia in moderately painful procedures, such as dentistry, obstetrics, and fractures
  • Conscious sedation – effective and safe sedation technique for the reduction of stress in the apprehensive or anxious individual

Nitrous oxide is sometimes used as an adjuvant of balanced anesthesia for surgical interventions, enabling reduced doses of other drugs and facilitating their post-operatory elimination.
