OBJECTIVE: To explore the effect of inadequate analgesia for painful procedures (bone marrow aspiration, lumbar puncture, or both) on the pain of subsequent procedures. DESIGN: A cohort of patients with cancer who had participated in aplacebo-controlled, randomized study that documented the efficacy of oral transmucosal fentanyl citrate for painful procedures rated the pain associated with subsequent procedures performed with open-label oral transmucosal fentanyl. PARTICIPANTS: Twenty-one children undergoing diagnostic procedures who had been participants in previous study. INTERVENTION: All children were given oral transmucosal fentanyl, 15 to 20 microgram/kg, prior to the procedure; at its conclusion they were asked to rate the associated pain. RESULTS: In children younger than 8 years (n = 13), mean pain ratings during each subsequent procedure were consistently higher for those who had received placebo (n = 8) in the original study compared with those who had received the active drug (n = 5). A repeated-measures analysis of variance suggests that this difference is statistically significant (P = .04). Older children (n = 8) did not show this pattern. CONCLUSION:Inadequate analgesia for initial procedures in young children may diminish the effect of adequate analgesia in subsequent procedures.
