    Abstract:
    OBJECTIVE: To identify the most effective sedation regimen for bone marrow aspiration and lumbar puncture procedures with a prospective trial of 3 combinations of sedation/analgesia. STUDY DESIGN: In this double-blind crossover study, we randomly assigned 162 children with acute lymphoblastic leukemia or lymphoblastic lymphoma to receive fentanyl 1 mcg/kg, fentanyl 0.5 mcg/kg, or placebo, in addition to propofol and topical anesthetic for 355 procedures. RESULTS: We found no significant differences among the 3 regimens in the frequency of pain (pain score > 0) or severe pain (pain score ≥ 5) during recovery, or a >20% increase in hemodynamic/respiratory variables during anesthesia. Treatment with fentanyl 1 mcg/kg was associated with a lower frequency of movement during procedure compared with treatment with fentanyl 0.5 mcg/kg (P = .0476) or treatment with placebo (P = .0545). The placebo group required longer time to recover (median, 18 minutes) compared with the fentanyl 0.5 mcg/kg group (median, 9 minutes) (median difference 2.0, P = .007) and the fentanyl 1 mcg/kg (median 8 minutes), (median difference 2.0, P = .15). The placebo group also required larger total dose of propofol (median 5 mg/kg) compared with that of the fentanyl 1 mcg/kg group (median, 3.5 mg/kg) and the fentanyl 0.5 mcg/kg group (median 3.5 mg/kg) (median differences 1.5, P < .00005, in both comparisons). CONCLUSION: The addition of fentanyl 1 mcg/kg to propofol for brief painful procedures reduces movement, propofol dose, and recovery time.
