Is there a dose response of dexamethasone as adjuvant for supraclavicular brachial plexus nerve block?
Low-dose dexamethasone (1-2 mg) prolongs analgesia duration and motor blockade to the similar extent as 4-mg dexamethasone when added to 0.25% bupivacaine for supraclavicular brachial plexus nerve block.
The AzBF showed a sustained decrease of value after a bolus injection of 50-μg OCT. A further hemodynamic response is detectable at OCT readministration after 60 minutes. The pattern of hemodynamic response to OCT may not be uniform among cirrhotics.
