  • Title: The effects of propofol and thiopentone on forearm circulation.
    Author: McKeating K, Howe JP, McArdle L.
    Journal: Anaesthesia; 1990 Apr; 45(4):294-6. PubMed ID: 2337213.
    Abstract:
    Some effects of propofol and thiopentone induction on the peripheral circulation of healthy patients are examined using mercury strain gauge venous occlusion plethysmography of the forearm. Results indicate that both drugs produce a statistically significant decrease in mean arterial blood pressure and forearm blood flow. Forearm vascular resistance remains unchanged after either drug. These data suggest that bolus dose induction of anaesthesia with propofol does not cause arterial vasodilatation of the limb and that a cause for the reduction in mean arterial pressure must be sought elsewhere.
