The effects of discrete increases in the volume of an artificial space-occupying lesion on intracranial pressures and the systemic circulation were studied in six anaesthetised and artificially ventilated dogs. Each increase in volume, accompanied by an increase in supratentorial intracranial pressure, a decrease in supratentorial perfusion pressure, and an increase in transtentorial pressure gradient, induced alterations in the systemic circulation. There were a decrease in heart rate, marked alterations in the arrhythmia index, and increases in stroke volume and systemic vascular resistance. A period of transient systemic hypertension was noted to accompany each discrete increase in intracranial pressure.
在六只麻醉并进行人工通气的狗身上,研究了人工占位性病变体积的离散性增加对颅内压和体循环的影响。每次体积增加,伴随着幕上颅内压升高、幕上灌注压降低以及幕上下压力梯度增加,都会引起体循环的改变。心率下降,心律失常指数有明显改变,每搏输出量和体循环血管阻力增加。注意到每次颅内压离散性增加都伴有一段短暂的全身性高血压。
