Using nitrous oxide in modern anaesthesia has been questioned. We surveyed changes in use of nitrous oxide in Scandinavia and its justifications for the duration of the final two decades.
All now 191 departments of anaesthesia while in the Scandinavian nations have been requested by email to answer an electronic survey in SurveyMonkey.
One hundred and twenty-five (64%) in the departments responded; 4 had been excluded. The 121 departments supplied 807.520 standard anaesthetics annually. The usage of nitrous oxide was reported in eleven.9% of cases, ranging from 0.6% in Denmark to 38.6% in Iceland whilst volatile anaesthetics were employed in 48.9%, lowest in Denmark (22.6%) and highest in Iceland (91.9%). Nitrous oxide was co-administered with volatile anaesthetics in 21.
5% of standard anaesthetics [2.4% (Denmark) -34.5% (Iceland)]. Use of nitrous oxide was unchanged in 5 departments (4%), reducing in 75 (62%) and stopped in 41 (34%). Factors for decreasing or stopping utilization of nitrous oxide were relatively uniform in the 5 nations, essentially the most vital being that other agents were 'better',CRM1 whereas couple of put bodyweight on its potential threat for rising morbidity. Choice to end applying nitrous oxide was produced from the departments except in four situations. Of 87 maternity wards, nitrous oxide was used in 72, whereas this was the situation in 42 of 111 day-surgery units.
The usage of nitrous oxide has nearly decreased while in the Scandinavian countries, apparently since quite a few now want other agents. Big difference in practices in between the five countries were unexpected and apparently not justified on anticipated proof only."
