本文观察七氟醚的吸入浓度及氧化亚氮对小儿吸入诱导效果的影响,供临床参考。资料与方法 60例ASA Ⅰ级4～11岁小儿,随机分成三组,每组20例。Ⅰ组,吸入5%输出浓度七氟醚、60%氧化亚氮;Ⅱ组,吸入3.5%输出浓度七氟醚、60%氧化亚氮;豇组,仅吸入5%输出浓度七氟醚。全部患儿均不使用术前药,术前探视时与患儿进行充分交谈,讲明吸入诱导的方法和目的,获得小儿的良好配合。使用德国Drager公司的SA_2麻醉机和Va-por19.3七氟醚定量挥发器提供七氟醚和氧化亚氮,流量5L/min(氧气2L/min、氧化亚氮3L/min),用Artema mm204-7气体监护仪校正氧化亚氮浓度。使用
This article observed the inhalation concentration of sevoflurane and nitrous oxide on children induced by inhalation effect for clinical reference. Materials and Methods 60 ASA Ⅰ grade children aged 4 to 11 years old were randomly divided into three groups of 20 cases each. Group Ⅰ, inhalation of 5% output concentration of sevoflurane, 60% nitrous oxide; Ⅱ group, the inhalation of 3.5% output concentration of sevoflurane, 60% nitrous oxide; cowpea group, only inhaled 5% output concentration of sevoflurane. All children do not use preoperative drugs, preoperative visits with children fully talked about the method and purpose of induction of induction, access to children with a good fit. Sevoflurane and nitrous oxide were provided using a Dra_2 SA 2 anesthesia machine and a Va-por 19.3 sevoflurane quantitative volatilizer at a flow rate of 5 L / min (oxygen 2 L / min, nitrous oxide 3 L / min) with Artema mm 204 -7 Gas monitor calibrates nitrous oxide concentration. use
