The aim of this study is to demonstrate how easy and suitable is the closed system in infants and children. An original circuit, adapted from the Bain-Spoerel system, is used. Its principle is to draw-up the expired gas through a soda lime canister by a pump, whose flow is 14 l.min-1. ("Circuit Bisontin"). For this study, 20 infants and children underwent anesthesia with isoflurane, in spontaneous or mechanical ventilation (with a "bag in the bag" principle ventilator). The lowest body weight was 2.7 kg. The advantages are a minimal dead space and no expenditure of energy during spontaneous ventilation thanks to an internal high flow and the absence of internal one-way valve. Gas monitoring is achieved by a four gas analyser (Capbomac Datex).
本研究的目的是证明封闭系统在婴幼儿中是多么易于使用和合适。采用了一种源自贝恩 - 斯波雷尔系统的改良原始回路。其原理是通过一个流量为14升/分钟的泵，经苏打石灰罐抽取呼出气体（“Bisontin回路”）。在本研究中，20名婴幼儿接受了异氟烷麻醉，采用自主通气或机械通气（使用“袋中袋”原理的呼吸机）。最低体重为2.7千克。其优点是死腔最小，由于内部高流量以及没有内部单向阀，在自主通气时无需消耗能量。气体监测通过四气体分析仪（Datex公司的Capbomac）完成。
