【摘要】 目的 :观察低流量循环麻醉的临床效果。方法 :选择择期胆囊摘除手术 2 6例 ,每组 13例 ,分别接受低流量 (0 .4～ 0 .6L/min)或高流量 (3.0L/min)恩氟烷循环麻醉 ,观察两组麻醉期间的SBP、HR、PETCO2 、SPO2 、FiO2 、FiEnf、FETEnf及新鲜气体流量 ;统计学处理采用t检验和 χ2 检验。结果 :两组麻醉期间SBP、HR、PETCO2 、FiEnf、FETEnf差异不显著 (P >0 .0 5 ) ;与高流量麻醉组相比 ,低流量麻醉组恩氟烷投入量小、利用率高 (P <0 .0 1) ,且FiO2 总高于 0 .6。结论 :低流量循环麻醉与高流量麻醉同样安全、麻醉过程平稳 ,且具有节省麻醉药、提高麻醉气体利用率的优点。更多还原

【Abstract】 Objective:To observe the clinical effects of low-flux circuit anesthesia with enflurane.Methods:26 patients, ASAⅠ～Ⅱ,undergoing elective cholecystotomy under enflurane anesthesia,were divided into two groups according to the oxygen flux used:group A(n=13),O 2= 0.4～ 0.6L/min,and group B(n=13),O 2= 3.0L/min. Statistical analysis was accomplished using t test,Chi square,and P< 0.05 was considered significant.Results: SBP,HR,P ETCO 2,F iEnf and F ETEnf had no significan difference between two groups(P> 0.05).Group A had lower amounts and higher extraction rate of enflurane expensed,however,than group B(P< 0.01).F iO 2 in group A were never lower than 0.6.Conclusion:Low-flux enflurane anesthesia is safe and more steady in maintenance of anesthesia than high-flux.It can save anesthetics and increase extration rate of anesthetics.更多还原
