摘要

开胸后收缩压、舒张压和平均动脉全身血压下降(-12%)。收缩压、舒张压和平均肺动脉压立即下降(25%)。中心静脉压无变化。开胸前不能测量心输出量(HMV)和脑卒中量。然而,在开胸后10 ~ 30 min, HMV(+17%)、HMV指数(+30%)和脑卒中容量(+60%)均呈上升趋势。心率持续下降(-19%)。最大压力上升速率(dp/dtmax)最初增加不显著,随后下降(-10%)。商数dp/dt/p立即下降(下降-10%)。所有措施持续到开胸后30min。

[The hemodynamics of the lung circulation of minipigs after experimentally-caused Sedlarik's pulmonary embolism. II. Modification of the hemodynamics of the heart and circulation by thoracotomy].

The systolic, diastolic, and the mean arterial systemic blood pressure decreased after thoracotomy (by -12%). The systolic, diastolic, and the mean pulmonary arterial pressure showed an immediate decrease (by 25%). The central venous pressure was not changed. The cardiac output (HMV) and the stroke volume could not be measured before the thoracotomy. However, the HMV (+17%), the HMV-index (+30%), and the stroke volume (+60%) increased from the 10th to the 30th min after the thoracotomy. The heart rate decreased continuously (by -19%). The maximum rate of pressure rise (dp/dtmax) increased primarily insignificantly and decreased afterwards (by -10%). The quotient dp/dt/p decreased immediately (by -10%). All measures were carried out until the 30th min after thoracotomy.
