摘要 目的探讨1.5mg/ml左布比卡因和40μg/ml吗啡单独或联合应用对大肠杆菌、金黄色葡萄球菌、粪肠球菌体外生长的影响。方法菌株在琼脂培养基中稀释至7.5×105cfu/ml,细菌悬液在37℃麻醉药中培养48h。结果左布比卡因抑制大肠杆菌生长(61±0.7%;P<0.05),金黄色葡萄球菌(23±3.6%;P<0.05),对粪肠球菌生长无抑制作用。40μg/ml吗啡单独仅对金黄色葡萄球菌有抑制作用(13.8±3.1%;P<0.05)吗啡能够增加左布比卡因对粪肠球菌、金黄色葡萄球菌10%(P<0.05)和大肠杆菌7%(P<0.05)的抑制效果。结论左布比卡因和吗啡单独或联合应用对大肠杆菌、金黄色葡萄球菌生长抑制作用,粪肠球菌对吗啡和左布比卡因混合液敏感。吗啡对左布比卡因抑菌有协同作用。
