Objective. To investigate the efficacy and safety of oral transmucosal
fentanyl (OTFC) in providing analgesia and sedation for painful diagn
ostic procedures in children. Design. Randomized, placebo-controlled c
linical trial. Method. Forty-eight children referred to the University
of Connecticut Division of Pediatric Hematology/Oncology for bone mar
row aspiration or lumbar puncture were randomized to receive either OT
FC (15 to 20 mu g/kg) or a placebo lollipop. Thirty minutes after admi
nistration, the procedure was begun. An anesthesiologist monitored the
child's heart rate, blood pressure, and oxygen saturation every 10 mi
nutes. At the conclusion of the procedure, the nurse, the child's pare
nt, and all children over 8 years of age were asked to rate the pain a
ssociated with the procedure using a 1 to 10 visual analogue scale. Yo
ung children (less than 8) used a modified scale, the Oucher, yielding
a 0 to 5 score. Results. Significant differences in pain ratings betw
een the OTFC and placebo groups were noted on the pain scores of the p
arents (P =.005), nurses (P =.001), younger children (P =.006), and ol
der children (P =.013), and median pain scores in the OTFC group were
reduced to tolerable levels. Vomiting (P =.003) and itching (P =.001)
were more common in the OTFC group, but no clinically significant vita
l sign deviations occurred. Conclusion. OTFC is safe and effective for
use in relieving the pain of pediatric procedures, but frequency of v
omiting may restrict its clinical usefulness.
