Table 2. Changes of the intraventricular pressure, mean arterial pressure, and pulse rate due to bilateral common jugular venous clipping.

Time point	IVP (mmHg)	p-value	MAP (mmHg)	p-value	PR (beats/min)	p-value
Before	6.9±3.1		97.2±11.2		392.3±57.1
During	9.2±3.5	0.008	90.0±10.2	0.008	395.1±48.8	0.678
<30sec After	6.8±3.0	0.110	96.3±10.2	0.441	393.0±50.7	0.859
>30sec After	7.4±3.4	0.767	97.0±8.7	0.953	377.0±42.1	0.260

(n = 9).

<30 sec After: less than 30 seconds after bilateral common jugular venous clipping.

>30 sec After: more than 30 seconds after bilateral common jugular venous clipping.

Abbreviations: IVP, intraventricular pressure; MAP, mean arterial pressure; PR, pulse rate. For p-values, comparison is to the initial time point (before bilateral common jugular venous clipping).
