Table 1.

Systemic arterial and calf occlusion pressures (mmHg) prior to, immediately after and 24 h following arterial catheterization

	Preinsertion	Postinsertion	P value	24 h	P value
Mean systemic arterial pressure	76 ± 11	80 ± 12	0.11	79 ± 11	0.44
Catheter leg maximum occlusion pressure	112 ± 21	108 ± 27	0.41	117 ± 26	0.65
Noncatheter leg maximum occlusion pressure	111 ± 33	111 ± 28	0.89	114 ± 18	0.82

Values are shown as mean± SD. P values of postcatheterization and 24 h measurements are with regard to preinsertion values.
