title: Pre-induction of anesthesia in pediatric patients with nasally administered sufentanil.
abstract: To evaluate nasally administered sufentanil, 1.5-4.5 micrograms/kg, for pre-induction (i.e., pre-medication/induction) of anesthesia in pediatric patients, the authors studied ASA PS 1 or 2 patients scheduled for elective surgery. Eighty children, ages 6 months to 7 yr, were randomized to receive sufentanil (1.5, 3.0, or 4.5 micrograms/kg) or placebo (normal saline, 0.03 ml/kg) nasally over 15-20 s. Induction of anesthesia was completed with 5% halothane and O2 via facemask. After tracheal intubation, anesthesia was maintained with N2O (60-70%) and halothane, as clinically indicated. A blinded observer remained with the child from prior to drug administration until discharge from the recovery room. Patients given sufentanil were more likely to separate willingly from their parents and be judged as calm at or before 10 min compared to those given saline. Ventilatory compliance during induction of anesthesia decreased markedly in 25% of subjects given sufentanil, 4.5 micrograms/kg. Subjects given sufentanil moved or coughed less during tracheal intubation and required less halothane compared to those given placebo. During recovery, patients given sufentanil cried less and fewer needed analgesics; recovery times were similar for all groups. However, patients given sufentanil, 4.5 micrograms/kg, had a higher incidence of vomiting in the recovery room and during the first postoperative day. The authors conclude that nasally administered sufentanil, 1.5 or 3.0 micrograms/kg, facilitates separation of children from parents, has minimal side effects, may improve intubating conditions, and can provide postoperative analgesia.
