Effect of preoperative education on anxiety in children undergoing day-care surgery

Abstract

Background and Aims: There have been various methods tested for reducing preoperative anxiety in children, but very limited literature is available in the Indian scenario. Our aim was to analyse the effect of an informative video about the anaesthetic technique on preoperative anxiety in children. Methods: In all, 94 children were randomly allotted into two groups. Children in the study group were shown a peer modelling video depicting induction of general anaesthesia and recovery during the preanaesthetic check (PAC). Patients in the control group were given only verbal information during PAC. Anxiety was assessed on visual analog scale (VAS) for anxiety at two times. Baseline VAS score was recorded during PAC and preoperative VAS score was assessed prior to induction of anaesthesia. The VAS score was represented as median value. Data were analysed using the Mann–Whitney U-test for ordinal data and skewed quantitative data. Categorical data was analysed by using Chi-square test and t-test was applied for quantitative data. The significance threshold of P value was set at <0.05. Results: The median (interquartile range) preoperative VAS score was significantly lower in the study group [1 (0–1.3)] when compared with the control group [5 (3–5)] (P < 0.001). The mean preoperative pulse rate, mean preoperative systolic blood pressure and mean preoperative diastolic blood pressure were significantly lower in the study group when compared with the control group (P < 0.001). Conclusion: Multimedia information in the form of a peer modelling video helped reduce preoperative anxiety in children between 7 and 12 years of age.
