Activation of the sympathetic nervous system appears to be relevant in some patients with unexplained pain after cholecystectomy, particularly those who show increases in plasma transaminase activity after challenge with morphine (morphine responders). In this study, the hypothesis that dexamethasone would improve chronic biliary pain, perhaps by suppressing activation of the sympathetic nervous system, was tested in a double-blind, placebo-controlled, cross-over trial in 20 patients, 10 morphine responders and 10 nonresponders. Before treatment with dexamethasone and placebo, urinary excretion of norepinephrine (NE) was significantly higher (p less than 0.05) in morphine responders than in nonresponders. During treatment with dexamethasone, 1 mg each night for 4 weeks, neither morphine responders nor nonresponders showed a significant improvement in pain or nausea or a significant reduction in sympathoadrenomedullary activity as assessed by urinary excretion of catecholamines. At the dose administered, dexamethasone was unhelpful for chronic pain after cholecystectomy and did not result in suppression of the sympathetic nervous system as assessed by urinary excretion of NE.
