Preparation of parents by teaching of distraction techniques does not reduce child anxiety at anaesthetic induction.

  For those children having surgery, induction of anaesthesia is one of the most stressful procedures the child experiences perioperatively. Current work has failed to show a benefit of parental presence at induction of anaesthesia for all children. The reasons for lack of effect may include the high anxiety levels of some parents and also that the role for parents at their child's induction is not delineated. The main aim of this study was to see if parental preparation by teaching of distraction techniques could reduce their child's anxiety during intravenous induction of anaesthesia. Methods  After ethics committee approval 40 children aged 2–10 years old, ASA status I or II undergoing daycase surgery under general anaesthesia were enrolled into the study. To avoid possible confounding factors children with a history of previous, surgery, chronic illness or developmental delay were excluded form participation. No children were given sedative premedication. After written informed consent by the parent, each child and parent was randomly assigned to an intervention or control group. Parents in the intervention group received preparation from a play specialist working on the children's surgical ward. It involved preparation for events in the anaesthetic room and instruction on methods of distraction for their child during induction using novel toys, books or blowing bubbles appropriate to the child's age. Preoperative information collected included demographic and baseline data. The temperament of the child was measured using the EASI (Emotionality, Activity, Sociability, Impulsivity) instrument of child temperament(l). In the anaesthetic room all children were planned to have intravenous induction of anaesthesia after prior application of EMLA cream. Anxiety of the child was measured by the modified Yale Preoperative Anxiety Scale (mYPAS)(2) by a blinded independent observer at three time points: entrance to the anaesthetic room, intravenous cannulation and at anaesthesia induction. Cooperation of the child was measured by the Induction Compliance Checklist (ICC) by the same observer (3). Postoperative data collected included parental satisfaction and anxiety scores measured by the Stait Trait Anxiety Inventory (STAI)(4) and at one week the behaviour of the child was measured Using the Posthospitalisation Behavioural Questionnaire (PHBQ)(5). Normally distributed data were analysed by a two‐sample t‐test, categorical data by Pearson's Chi‐squared test and non‐parametric data by the Wilcoxon rank‐sum test. Results  One parent withdrew after enrolment. This left 22 children in the control group and 17 in the intervention group. There were no significant differences in demographic and baseline data of the children between the two groups including ethnic origin, number of siblings, birth order of the child, recent stressful events in the child's life, previous hospital admissions and the temperament of the child. Parent demographics were also similar between groups including parent's age, sex, relationship to child and level of education. There were no significant differences in child anxiety or cooperation during induction measured by mYPAS and ICC between the control and intervention groups. More parents in the preparation group distracted their child than those without preparation but this did not reach significance. Parental anxiety immediately postinduction was similar between groups as was the level of parental satisfaction. The incidence of development of new negative postoperative behaviour of the child at one week was not significantly different between groups. Discussion  This study shows that giving an active role for parents in the induction room, particularly by instructing them on distracting techniques for their child, does not reduce their child's anxiety compared to conventional parental presence. We conclude resources should not be directed at this type of parental preparation. Further work should examine the usefulness of distraction by nursing staff or play specialists during anaesthetic induction.
