“… 3 However, negative middle ear pressure is less easily equilibrated. 4 N 2 O is also associated with postoperative nausea and vomiting (PONV). 5 Negative pressure alone has not demonstrated a relationship with the development of PONV.…”

“…During recovery the nitrous oxide diffuses out rapidly and collapse of the walls of the eustachian tube prevents equilibration with atmospheric pressure (Perreault et al 1982;Blackstock & Gettes 1986). Montgomery and colleagues (1988) did not find any association between negative middle ear pressure and postoperative vomiting.…”

The effect of avoiding nitrous oxide during anaesthesia for myringotomy as an outpatient procedure in children aged 18 months to 10 yr was investigated. One hundred and four chldren were allocated randomly to receive either nitrous oxide, oxygen and halothane or oxygen and halothane for maintenance of anaesthesia. Ten of 47 (21%) children receiving nitrous oxide experienced postoperative vomiting, compared with two of 48 (4%) of those that did not receive nitrous oxide (P < 0.05). The possible mechanisms are discussed.

“…Pathophysiologisch werden verschiedene Mechanismen diskutiert, über die N 2 O emetogen wirken könnte: durch Diffusion in Darm und Mittelohr [16,124], über die Aktivierung des dopaminergen Systems [109] und über die Freisetzung von Opioidpeptiden in den Liquor [41]. Unter hyperbaren Bedingungen erwies sich N 2 O, angewendet als Monosubstanz bei gesunden Probanden, als emetogen [134].…”

Nitrous oxide has been used in addition to other volatile anaesthetics to provide general anaesthesia and short time sedation for more than 150 years. However, the exact mechanisms of action remain unclear. For decades nitrous oxide was considered to be the ideal anaesthetic because of his favourable physical properties and low cardiovascular side effects. However, the known side effects of nitrous oxide as well as the implementation of new anaesthetic agents and short acting opiates led to more and more criticism about the administration of this gas. Nitrous oxide is still frequently used for mask induction primarily in paediatric anaesthesia and gynaecology. However, recent studies have shown that omitting nitrous oxide can also be a risk factor because of an increased susceptibility to intraoperative awareness. Careful consideration of the illustrated contraindications and side effects as well as the available alternatives, shows that nitrous oxide is still an option in general anaesthesia.
