Protocols of nine patients in shock are presented. In each instance intense vasoconstriction and reduced tissue perfusion was present whether the shock was duo to hemorrhage, gram-negative sepsis, or cardiac decompensation. The calculated value for total peripheral resistance was misleading in patients suffering hemorrhagic or septic shock. The value of this calculation is not that of an absolute number reflecting the magnitude of vasoconstriction, but is influenced greatly by the presence of arteriovenous shunting which is especially prominent in septic shock. These findings emphasize that the intensity of vasoconstriction and reduced tissue perfusion is best gauged by careful bedside observations of skin color and temperature and urine output.
