In the course of celiac plexus alcohol block, facial flushing, palpitations, and hypotension are occasionally incurred in some patients. We hypothesized that the phenomenon represents acetaldehyde syndrome, not response to increased blood levels of ethanol as might be supposed. In order to prove our hypothesis, we selected five patients scheduled to undergo celiac plexus alcohol block, and, with their consent, we measured blood concentration of ethanol and acetaldehyde before and for 6 hr after the block. We also determined the phenotypes of aldehyde dehydrogenase (ALDH) in their hair roots. We found that "flushers" are found exclusively among subjects without ALDH I, and that their blood levels of acetaldehyde were significantly higher than those of "non-flushers" within 10 min after the block. The flushers also gave histories of facial flushing after ingestion of small amounts of ethanol. On the basis of such histories one can anticipate whether acetaldehyde syndrome is likely or unlikely to accompany the block.
