高渗氯化钠羟乙基淀粉40注射液高容量血液稀释对大鼠肝脏缺血再灌注损伤的影响

Objective To investigate the effects of hypervolemic hemodilution (HH) with hypertonic saline plus hetastarch solution 40 injectio on hepatic ischemia-reperfusion (I/R) injury in rats. Methods Thirty male Wistar rats weighing 300-350 g were randomly divided into 3 groups ( n = 10 each): group I sham operation (group S); group II I/R and group Ⅲ HH. Partial liver ischemia was produced by clamping hepatic portal vein and left arteria hepatica for 30 min with atraumatic mini-clamp, followed by 2 h of reperfusion in I/R group and HH group. In HH group the animals were infused hypertonic saline plus hetastarch solution 40 injectio 10 ml/kg through vena caudalis over 30 min and then hepatic I/R was performed IS min after the infusion.The animals were killed at 2 h of reperfusion. The left liver was removed and blood sample was taken from inferior caval vein for determination of (1) serum alanine amino transferase (ALT) and aspartate amino transferase (AST) activities; (2) superoxide dismutase ( SOD) activity and malondialdehyde ( MDA) content in the liver; ( 3 ) microscopic examination. Results The serum ALT and AST activities and MDA content in the liver were significantly higher, SOD activity in the liver significantly lower after hepatic I/R and pathological changes in the liver severer in group I/R and HH than in group S. The serum ALT and AST activities and MDA content in the liver were significantly lower, SOD activity in the liver significantly higher after hepatic I/R and pathological changes in the liver milder in group HH than in group I/R. Conclusion Hypervolemic hemodilution with hypertonic saline plus hetastarch solution 40 injectio can ameliorate hepatic I/R injury by decreasing oxygen free radical production in rats.     

6%羟乙基淀粉130/0.4对患者硬膜外复合全麻诱导期肺循环的影响

Objective To observe the effect of pulmonary circulation by 6% hydroxyethyl starch 130/0.4 during induction period from epidural block combined with general anesthesia. Methods Twenty-six hepatobiliary surgical patients with ASA Ⅰ-Ⅱ, aged 32 y-59 y, weighing 54 kg-73 kg, were randomized into 2 groups(n=13): hydroxyethyl starch 130/0.4 group(HS)and complex acetic acid Ringer's solution (RL). Above-mentioned solutions were infused 7 ml/kg respectively before induction. The pulmonary circulation hemodynamic parameters such as pulmonary arterial systolic pressure (PASP), pulmonary arterial diastolic pressure (PADP), mean pulmonary artery pressure(MPAP), pulmonary artery wedge pressure(PAWP), pulmonary vascular resistance(PVR) and right ventricular stroke work(RVSW) were recorded at base value(T0), 10 min after infusion(T1), 5 min after induction(T2), 5 rain after intubation(T3), 10 rain after intubation(T4)and 20 min after intubation(T5). Results PASP、PADP、MPAP、PAWP and CVP were significantly higher in group HS at T, than the values at T0 (P<0.05); PVR in group HS was obviously lower from T1 to T5 than the value at To (P<0.05 or P<0.01); RVSW was significantly higher in two groups at T1 than base value (P<0.05), but that in group HS was lower than base value (P<0.05 or P<0.01); HR obviously decreased in two groups from T2 to T5 as compared with the value at T0 (P<0.05); MAP was lower from T3 to T5 than the value at To (P<0.05 or P<0.01). PVR was obviously lower in group HS from T1 to T5 than that in group RL (P<0.05 or P<0.01); MAP obviously increased from T2 to T5 in group HS as compared with the value in group RL(P<0.05 or P<0.01). Conclusion 6% hydroxyethyl starch 130/0.4 can obviously reduce PVR during induction pe-riod from epidural block combined with general anesthesia. In all, there is no effect on pulmonary circulation by 6% hydroxyethyl starch 130/0.4.
