BackgroundApproaches to pediatric induction of anesthesia vary widely. While oral sedative premedication and inhalational induction are common, total intravenous anesthesia is becoming increasingly popular. Total intravenous anesthesia without anxiolytic premedication, which is the most commonly used technique in our hospital, requires intravenous (IV) cannula placement in an awake child.AimsTo quantify the success rate of IV cannula placement in 1 or 2 attempts and to identify success factors and barriers.MethodsWith ethical approval and written informed consent from participating anesthesiologists, a prospective audit of IV cannulation was undertaken over a 1-month period. The attending anesthesiologist captured basic demographics, IV insertion characteristics, setting, distraction techniques, the behavior of the child, number of attempts, and success/failure. A logistic regression model for successful IV cannulation was created. Anesthesiologists and procedural suite nurses participated in semi-structured interviews to identify success factors, barriers, and teaching approaches.ResultsData from 984 cases were analyzed. IV induction was planned in 562 cases, and IV cannulation was successful in 90% of these patients. Anxiolytic premedication was given in 6% of cases. Observations indicated that 64% of children were pain- and reaction-free, and 90% experienced minimal or no reaction. Predictors for success included older child's age and child behavior at first encounter. Qualitative interview data from 13 participants suggested success factors included effective distraction, preparing the family for IV induction, parental presence, support of the operating room team, effective use of local analgesic cream, adapting the approach to the individual child, and the anesthesiologist's efficiency. Barriers included needle phobia, uncooperative child, anxious parents, ineffective use of analgesic cream, and unfavorable anatomy. Distraction techniques varied by age and developmental stage of the child.ConclusionsCannulation for planned IV induction is feasible for most children, enabling increased use of total intravenous anesthesia as an institutional anesthetic strategy.© 2020 John Wiley & Sons Ltd.
