The potential risk of vascular compromise to\n\t\t\t\tthe limb may be exacerbated in patients receiving vasopressors. The utility of\n\t\t\t\tscanning laser Doppler flowmetry to measure changes in pedal perfusion\n\t\t\t\tfollowing catheterization was assessed.\n        \n        \n          Results:\n          There were no significant changes in mean occlusion pressures or\n\t\t\t\tin cutaneous perfusion between either leg or between measurement time points,\n\t\t\t\timmediately after or 24 h following insertion of the catheters.\n        \n        \n          Conclusions:\n          Scanning laser Doppler flowmetry is easily used to assess changes\n\t\t\t\tin foot perfusion and the effect of interventions that may reduce blood flow to\n\t\t\t\tthe skin of the foot.
