Studying the human forearm vascular bed in patients with septic shock, we tested the hypothesis that the responses to regionally infused endothelium\u2010(in)dependent vasodilators and vasoconstrictors are uniformly impaired. Forearm blood flow (FBF, venous occlusion plethysmography) and brachial arterial pressure were determined to calculate forearm vascular resistance (FVR) in eight consecutive sedated, mechanically ventilated patients with septic shock (APACHE II Score range 21\u201334, SOFA Score 11\u201316) and 11 healthy volunteers. Despite increased baseline FBF in patients with septic shock (6.1 (SD\u20031.5) ml.min\n                    <jats:sup>\u22121<\/jats:sup>\n                    .(100\u2003ml of tissue)\n                    <jats:sup>\u22121<\/jats:sup>\n                    compared to 4.7 (1.4) in volunteers) the significant decreases in FVR seen in response to exogenous nitric oxide (nitroprusside) and acetylcholine did not differ between groups.

In contrast, vasopressin, in dosages evoking no vasoconstriction in volunteers, induced a significant increase in FVR in septic patients (+\u200310.0\u2003mmHg.min.ml\n                    <jats:sup>\u22121<\/jats:sup>\n                    ).
