摘要
目的:观察口服异氟烷(Iso)、七氟烷(Sev)对小鼠的镇痛及催眠等麻醉作用。方法:按分层随机设计,将180只小鼠分为18组(n=10),分别用于热板实验、扭体实验(各60只):对照组(生理盐水(NS)组),Iso1、Iso2、Iso3组(1、2、3mL·kg-1),Sev1、Sev2组(5、10mL·kg-1)。催眠实验(60只):对照组(NS组),Iso1、Iso2、Iso3组(6、8、10mL·kg-1),Sev1、Sev2组(20、40mL·kg-1)。小鼠Iso、Sev灌胃后用热板和扭体实验观察小鼠热板痛阈值(HPPT)和扭体次数的变化情况,以评估镇痛作用;用催眠实验的睡眠时间变化情况评估催眠作用。结果:与对照组比较,Iso(1~3mL·kg-1)、Sev(5、10mL·kg-1)灌胃能增加HPPT值,减少扭体次数(P<0.05,P<0.01);Iso(6~10mL·kg-1)、Sev(20、40mL·kg-1)灌胃后能延长睡眠时间(P<0.01)。结论:在本实验条件下,小鼠Iso、Sev灌胃可产生有效的催眠和镇痛等麻醉作用。
OBJECTIVE: To investigate the analgesic and hypnotic effects of oral isoflurane (Iso) and sevoflurane (Sev). METHODS: 180 mice were randomly divided into 18 groups (n= 10). It included in hot-plate test (n=60), writhing test (n= 60), i.e. NS group, Iso1 group (1 mL·kg^-1), Iso2 group (2 mL·kg^-1), Iso3 group (3 mL·kg^-1), Sev1 group (5 mL·kg^-1), Sev2 group (10 mL·kg^-1). Another six groups were included in sleeping test, i.e. NS group, Isol group (6 mL·kg^-1), Iso2 group (8 mL·kg^-1), Iso3 group (10 mL·kg^-1), Sev1 group (20 mL·kg^-1), Sev2 group (40 mL·kg^-1). Hot-plate test, writhing test, sleeping test were employed to evaluate the hot-plate pain threshold (HPPT), writhing times (WT) and sleeping time (ST) respectively after i.g. administration of Iso and Sev to evaluate analgesic and hypnosis effect. RESULTS: As compared with NS group, Iso ( 1 3mL·kg^-1) and Sev(5, 10mL·kg^-1) with intragastric administration could increase the HPPT and decrease the WT(P〈0.05,P〈 0.01). Iso (6-10mL·kg^-1)and Sev (20, 40mL·kg^-1) with intragastric administration could extend the ST(P〈0.01). CONCLUSION: In this study, Iso and Sev represent effective analgesic and hypnotic effect with intragastric administration.
