Summary In order to explore the mechanism of hemodynamic changes caused by high biliary tract pressure, we established an animal model
of high biliary tract pressure, in which the disturbance of hemodynamics developed. The cervical or abdominal vague nerve
was then blocked. It was observed that when the biliary tract pressure was increased to 16 kPa and kept for 1 h, the arterial
blood pressure and cardiac output decreased immediately and parallelly (P<0.05). When the cervical or abdominal vague nerve were blocked or the pressure of the biliary tract was decreased to zero,
both indices returned to normal immediately (P> 0. 05). The change of cardiac output lags a little behind that of arterial blood pressure. It suggests that the signal of
biliary tract pressure increase can be sent to the cardiovascular center through vague nerve, and the balance between sympathic
and parasympathic nerve was broken, which led to the weakening of cardiac contraction and decrease of cardiac output. Due
to the peripheral effects of vague nerve, hemodynamic resistance of vessels decreased, which brought about redistribution
of peripheral blood flow. Both were the causes of hemodynamic disturbances. After the blood pressure decreased markedly, it
showed a jump to normal state when cervical vague nerve was blocked. And the amplitude of diastolic blood pressure restored
more than that of systolic blood pressure. This suggests that the cardiac output and peripheral blood resistance are important
factors that cause the decrease of blood pressure. 相似文献

目的 以迷走神经为对象 ,研究胆管加压所致机体心血管活动变化的神经机理。方法 采用自制“盲囊”导管制成家兔急性胆管加压模型 ,观察动物的动脉血压及心输出量改变情况。结果 持续胆道加压 ,家兔的动脉血压和心输出量几乎平行快速下降 (P <0 .0 5 ) ;这种变化在阻断颈部或腹部迷走神经后 ,又很快恢复至加压前水平 (P >0 .0 5 ) ,但动脉血压和心输出量的恢复速度 ,按迷走神经的阻断部位不同而有所差异。结论 胆道高压所致的家兔血液动力学变化 ,与迷走神经的活动有关 ,并且推断可能是一种神经反射机制。 相似文献

Summary In order to explore the effect of biliary tract pressure on Oddi’s sphincter and the mechanism of development of high pressure
of biliary tract during acute obstructive and suppurative cholangitis (AOSC), house rabbits were used to establish model of
high biliary pressure in acute biliary duct caecus. It was observed that when the pressure of the acute biliary tract was
increased to 8 kPa, the electric activity of Oddi’s sphincter was obviously enhanced, the pressure of Oddiœs sphincter increased
remarkably (P <0. 05), and even constant spasm appeared with accompanying increase of discharge frequency of the right greater splanchnic
nerves (P <0. 05) and progressive decrease of mean arterial pressure. However, when lidocaine of 0. 6 % was used to block the right
celiac plexus, no above-mentioned reaction happened when the biliary tract pressure was increased again. The results indicated
that the acute biliary tract obstruction might induce the contraction or spasm of Oddi’s sphincter and bring about a vicious
cycle. Its mechanism is related to splanchnic nerves reflection and it is one of important factors in the development of AOSC
course.

目的探讨不同腹腔内压力(IAP)对急性肺损伤(ALI)家猪呼吸力学及血流动力学的影响。方法将8只家猪经耳缘持续静脉泵入油酸0.1 mL/kg制作急性肺损伤模型,采用氮气气腹法制作不同腹腔压力模型,随机将IAP设置为0、15和25 mm Hg,即分为IAP0组、IAP15组和IAP25组,动态监测心率(HR)、平均动脉压(MAP)、中心静脉压(CVP),采用脉搏轮廓持续心排出量监测(PiCCO)法动态监测心排出量(CO)、胸腔内血容量指数(ITBVI)等血流动力学指标,同时置入食管内压管动态监测食管内压(Pes)的变化。结果 IAP15组、IAP25组与IAP0组比较,Pes和气道峰压(Ppeak)均显著增加(P<0.01),肺顺应性(Cstat)则显著下降(P<0.05),跨肺压(Ptp)呈下降趋势,PaO2亦呈下降趋势,PaCO2则呈上升趋势,但均无统计学意义(P>0.05)。IAP15组、IAP25组与IAP0组比较,HR和CVP显著增加(P<0.05),CI和ITBVI则显著下降(P<0.05),但MAP无明显改变(P>0.05);ΔPes与CI的变化(ΔCI)呈负相关(r=-0.648,P<0.05)。结论急性肺损伤时,腹腔内压增高引起胸腔内压力增高,导致肺顺应性下降和心排出量下降。 相似文献

本文分析了我院近十年的36例重症胆管炎(ACST)患者,结果显示:依梗阻是否完全,ACST可分成急性梗阻化脓性胆管炎(AOSC)和急性化脓性胆管炎(ASC),前者发展凶猛,死亡率极高,后者则预后较好。另外本文采用44只日本种长耳家兔以不同胆道梗阻制成胆道管炎模型,结果也证实,完全梗阻组48小时血压下降幅度达7.6kpa(55mmHg),较不全梗阻组(4kpa)为高(p<0.05),作者认为:胆道梗阻程度是ACST病情发展的重要因素。文中发现血内毒素与血压变化并不平行,可能存在其它影响因素。 相似文献
