目的：探讨腹部肿瘤患者麻醉中七氟醚饱和状态后降低氧流量的效果。方法40例腹部肿瘤患者,拟在七氟醚吸入全身麻醉联合硬膜外麻醉下手术。潮气量(TV)设置为8 ml/kg, I：E=1：1.5,呼吸频率(RR)=10 bpm,新鲜气体流量(FGF)=分钟通气量(MV),设定浓度(Fd)为2.4%vol,呼气末浓度(Fet)达到峰值10 min后,记录吸入浓度(Fi)的数值。将FGF/MV从1降低到0.4,10 min内每隔1 min记录Fi和Fet的数值；然后将FGF/MV从0.4降低到0.3,同样方法记录Fi和Fet；最后将FGF/MV从0.3降低到0.2,同样方法记录Fi和Fet的数值。结果Fet达到峰值后,降低FGF/MV引起Fi轻度下降；相对于起始状态,在2 min和10 min时略有下降,但差异均无统计学意义(P>0.05),呼气末吸入浓度可以稳定在1.7%vol。结论在对肿瘤患者进行麻醉时,在七氟醚吸入麻醉达到饱和状态后降低流量具有很好的效果,具有良好的循环呼吸稳定性。

ObjectiveTo investigate effect of reducing oxygen flow rate in sevoflurane saturation of abdominal tumor patients.MethodsA total of 40 abdominal tumor patients received operation under sevoflurane inhalation anesthesia combined with epidural anesthesia. Tidal volume (TV) was 8 ml/kg, I:E=1:1.5, respiratory rate (RR)=10 bpm, fresh gas flow (FGF)=minute ventilation (MV), concentration set (Fd) was 2.4% vol, inspired concentration (Fi) was recorded after 10 min of end tidal concentration (Fet) peak. Fi and Fet were recorded in every 1 min during 10 min from reduced FGF/MV from 1 to 0.4, from 0.4 to 0.3, and from 0.3 to 0.2.ResultsAfter peak of Fet, reduced FGF/MV led to slightly reduced Fi, which was also reduced in 2 min and 10 min in the comparison with initial state. Their differences had no statistical significance (P>0.05). End tidal inspired concentration could be stabilized at 1.7% vol.ConclusionIn anesthesia for tumor patients, reducing oxygen flow rate in sevoflurane saturation can provide excellent effect and good stability in circular respiration.
