Using nitrous oxide in modern-day anaesthesia is questioned. We surveyed improvements in utilization of nitrous oxide in Scandinavia and its justifications through the last two decades.
All CRM1 191 departments of anaesthesia during the Scandinavian nations were requested by email to reply an electronic survey in SurveyMonkey.
1 hundred and twenty-five (64%) on the departments responded; 4 have been excluded. The 121 departments presented 807.520 general anaesthetics annually. The utilization of nitrous oxide was reported in eleven.9% of scenarios, ranging from 0.6% in Denmark to 38.6% in Iceland when volatile anaesthetics had been 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 basic anaesthetics [2.4% (Denmark) -34.5% (Iceland)]. Use of nitrous oxide was unchanged in five departments (4%), reducing in 75 (62%) and stopped in 41 (34%). Motives for decreasing or stopping use of nitrous oxide were pretty uniform within the five countries, quite possibly the most important currently being that other agents have been 'better',product information whereas number of put weight on its possible risk for rising morbidity. Determination to halt making use of nitrous oxide was made by the departments except in 4 cases. Of 87 maternity wards, nitrous oxide was used in 72, whereas this was the case in 42 of 111 day-surgery units.
The usage of nitrous oxide has find protocol decreased in the Scandinavian countries, apparently because quite a few now favor other agents. Big difference in practices involving the five nations were sudden and apparently not justified on anticipated evidence only."
