The effect of head-down tilt during general anesthesia on intracranial pressure (ICP) dynamics was examined in eight cats. Changes in lateral ventricular pressure (LVP), sagittal sinus pressure (SSP), and effective CSF pressure (ECSFP), which is the driving pressure of cerebrospinal fluid (CSF) absorption, were studied in association with a shift from the horizontal prone position to the 20 degrees head-down tilt position. Both LVP and SSP values were significantly (P < 0.01) increased at 10 min in the head-down tilt position as compared with the control position, remained elevated during the next 110 min, and returned to baseline when the horizontal position was restored. However, ECSFP (expressed by LVP - SSP) was not significantly different from the control value, because changes in LVP and SSP were similar. These results suggest that head-down tilt does not impair CSF absorption.
在八只猫身上研究了全身麻醉期间头低位倾斜对颅内压（ICP）动态变化的影响。研究了从水平俯卧位转变为头低位倾斜20度时侧脑室压力（LVP）、矢状窦压力（SSP）以及有效脑脊液压力（ECSFP，即脑脊液（CSF）吸收的驱动压力）的变化。与对照位置相比，头低位倾斜10分钟时LVP和SSP值均显著升高（P < 0.01），在接下来的110分钟内持续升高，恢复到水平位置时回到基线。然而，ECSFP（由LVP - SSP表示）与对照值无显著差异，因为LVP和SSP的变化相似。这些结果表明头低位倾斜不会损害脑脊液吸收。
