Abstract:The aim of this study was to compare the effect of three different induction techniques, with or without neuromuscular block, on tracheal intubation, haemodynamic responses and cardiac rhythm. Ninety children, aged 1-3 years, undergoing day-case adenoidectomy were randomly allocated to three groups: group TS received thiopentone 5 mg kg-1 and suxamethonium 1.5 mg kg-1, group H 5 Vol.% halothane and group PA alfentanil 10 micrograms kg-1 and propofol 3 mg kg-1 for induction of anaesthesia. No anti-cholinergics … Show more
“…In a recent study, the first attempt at tracheal intubation was unsuccessful in 20% of children aged 1–3 years after induction of anaesthesia with propofol 3 mg·kg –1 and alfentanil 10 μg·kg –1 . In the same study, all the procedures were successful when induction was performed with halothane 5% (2). Hansen et al .…”

“…These authors mentioned that they could not find published data on the frequency of use or the safety of this technique. Many authors reported acceptable conditions for tracheal intubation in 95–100% of the children when using halothane alone (2,3) or associated with opioids (4). Acceptable intubating conditions seem more difficult to achieve after induction of anaesthesia with propofol associated with alfentanil (2,5).…”

Sevoflurane is the most commonly used agent for tracheal intubation without relaxants with higher doses being required in infants aged less than 6 months. Propofol, even with opioids, was not so successful.

“…In these studies, satisfactory intubating conditions were found in 35-90% of children given propofol 3-4 mg/kg and alfentanil 15-20 mg/kg or remifentanil 1-2 mg/kg. By contrast, in two of the studies, satisfactory intubating conditions were obtained in more than 95% of a group of children given thiopental 5 mg/kg and SCh 1.5-2 mg/kg [10,13]. In one study, intubating conditions were improved by increasing the dose of remifentanil from 2 to 3 mg/kg [14], but this produced a significant reduction in heart rate and blood pressure.…”

“…Concerns about the dangers of SCh in children encouraged several studies of tracheal intubating conditions following the administration of propofol and a shortacting opioid drug [10][11][12][13][14]. In these studies, satisfactory intubating conditions were found in 35-90% of children given propofol 3-4 mg/kg and alfentanil 15-20 mg/kg or remifentanil 1-2 mg/kg.…”
Recent developments in clinical practice have reduced or obviated the need for muscle relaxants in pediatric anesthesia. Muscle relaxants are still indicated for intubation and procedures requiring profound muscle relaxation, and to minimize the amounts of anesthetic drugs given to infants and sick children. Specific relaxants and doses can be chosen to suit the clinical circumstances.
