High costs still limits the widespread use of xenon in the clinical practice. Therefore, we evaluated xenon consumption of different delivery modes during general surgery.
A total of 48 patients that underwent general surgery with balanced xenon anaesthesia were retrospectively analysed according to the mode of xenon delivery during maintenance phase (ECO mode, AUTO mode or MANUAL mode).
Xenon consumption was highest during the wash-in phase (9.4 ± 2.1l) and further decreased throughout maintenance of anaesthesia. Comparison of different xenon delivery modes revealed significant reduced xenon consumption during ECO mode (18.5 ± 3.7L (ECO) vs. 24.7 ± 11.5L (AUTO) vs. 29.6 ± 14.3L (MANUAL); p = 0.033). No differences could be detected with regard to anaesthetic depth, oxygenation or performance of anaesthesia.
The closed-circuit respirator Felix Dual offers effective reduction of xenon consumption during general surgery when ECO mode is used.
高昂的成本仍然限制了氙气在临床实践中的广泛应用。因此,我们评估了普通外科手术中不同输送模式下的氙气消耗量。
根据维持期氙气输送模式(ECO模式、AUTO模式或MANUAL模式),对48例行氙气平衡麻醉的普通外科手术患者进行回顾性分析。
氙气消耗量在冲洗期最高(9.4±2.1升),并在麻醉维持过程中进一步下降。不同氙气输送模式的比较显示,ECO模式下氙气消耗量显著降低(ECO模式为18.5±3.7升,AUTO模式为24.7±11.5升,MANUAL模式为29.6±14.3升;p = 0.033)。在麻醉深度、氧合或麻醉效果方面未发现差异。
当使用ECO模式时,闭路呼吸器Felix Dual可有效减少普通外科手术中的氙气消耗。
