Oral transmucosal fentanyl citrate (OTFC) is a labeled preoperative
pediatric sedative. Doses greater than 15 micrograms/kg are associated with
a high incidence of post-operative nausea and vomiting and occasional
respiratory depression. We studied the safety and efficacy of OTFC in
children 6 yr old and younger at a dose of 15 micrograms/kg. Nineteen
patients undergoing surgery associated with postoperative pain were
randomized to receive OTFC/intravenous (IV) saline or placebo lozenge/IV
fentanyl. After 45 min, patients receiving OTFC became more sedated than
the placebo group, but there were no differences in cooperation,
apprehension, parental separation, or induction cooperation scores.
Preoperatively, neither respiratory depression nor oxygen desaturation
occurred. Nine of 10 OTFC patients developed mild pruritus, and three of 10
OTFC patients vomited preoperatively; neither complication occurred in the
placebo group. (The high incidence of preoperative vomiting led to the
termination of the protocol before the anticipated enrollment of 40
patients.) General anesthesia was induced via a mask, followed by a
propofol infusion. Spo2 and respiratory rate were monitored, and sedation,
apprehension, cooperation, ease of parental separation, and induction
cooperation were scored. One OTFC patient developed rigidity during
induction. Emergence and recovery were not delayed by OTFC despite a 50%
incidence of postoperative vomiting. We do not recommend the use of OTFC in
a 15 micrograms/kg dose as a routine preoperative sedative in children 6 yr
old and younger.
