不同液体复苏对失血性休克兔微循环及炎性因子的影响
Effects of Different Fluids on Microcirculation and Inflammatory Factors in Rabbits with Hemorrhagic Shock
摘要
Abstract
Objective To study the effects of different types of fluid resuscitation on mesenteric microcirculation and inflammatory factors in rabbits with hemorrhagic shock.Methods The model of hemorrhagic shock rabbits was established by reducing the basic mean arterial pressure by 40%through draining the blood from the common carotid artery.Animals were randomly divided into control group,saline group,lactate Ringer group,acetic acid Ringer group,hydroxyethyl starch group and succinyl gelatin group with 8 animals in each group.Mesenteric microcirculation was monitored with microcirculation monitor.Mean arterial pressure(MAP),heart rate(HR),microvascular perfusion ratio(PPV)and microvascular blood flow index(MFI)were recorded before bleeding(T0),at hemorrhagic shock(T1),at the beginning of fluid resuscitation(T2),at the completion of fluid resuscitation(T3),and at the end of the experiment(T4).The contents of tumor necrosis factor-α(TNF-α),interleukin-1(IL-1)and lactic acid(Lac)were measured at T0,T2 and T4.Results Compared with hydroxyethyl starch group,there were statistically significant differences in T3 MAP(P<0.05),except for succinyl gelatin group,hydroxyethyl starch group had higher MAP at T4 than other groups,the difference was statistically significant(P<0.05).The differences in MAP between experimental control group and other groups were statistically significant at T4(P<0.05).PPV and MFI of hydroxyethyl starch group and succinyl gelatin group were higher than those of normal saline group,lactic acid Ringer group and acetic acid Ringer group at T4(P<0.05),and the lactic acid value of hydroxyethyl starch group at T4 was the lowest,compared with lactic acid Ringer group and normal saline group,the difference was statistically significant(P<0.05).There were statistical significances between all groups and experimental control group at T4(P<0.05).There were no significant differences in TNF-αand IL-1 in T0,T2 and T4 among all groups(P<0.05).Conclusion Hydroxyethyl starch solution and succinyl gelatin solution can improve the microcirculation of rabbits with hemorrhagic shock,but can not improve the level of inflammatory factors.关键词
