BACKGROUND: Negative postoperative behavioural changes (NPOBCs) are very frequent in children after surgery and general anaesthesia. If they persist, emotional and cognitive development may be affected significantly. OBJECTIVE: To assess whether the choice of different anaesthetic techniques for adenotonsillectomy may impact upon the incidence of NPOBC in repeated measurements. DESIGN: A randomised, controlled, parallel-group trial. SETTING: University Hospital Split, Croatia. PATIENTS: Sixty-four children (aged 6 to 12 years, ASA 1 to 2) undergoing adenotonsillectomy assigned into one of two groups: sevoflurane (S) (n = 32) or total intravenous anaesthesia (TIVA) (n = 32). INTERVENTIONS: Permuted-block randomisation with random block sizes of 4, 6 and 8, administering anaesthesia, and evaluation of NPOBC with the Post Hospitalization Behavior Questionnaire (PHBQ: 27 items describing six subscales). The PHBQ was filled out by parents at postoperative days (POD) 1, 3, 7 and 14, and 6 months after surgery. MAIN OUTCOME MEASURES: Differences in numbers of NPOBCs between two anaesthesia techniques, and NPOBC analysis by subscales. RESULTS: The prevalence of at least one NPOBC after surgery ranged from a maximum of 80% [95% confidence interval (CI) 71 to 90%] on POD 1 to a minimum of 43% (95% CI 31 to 56%) 6 months after surgery. Absolute risk reduction for at least one NPOBC in the TIVA group compared with the S group increased from 0.24 on POD 1 to 0.55 6 months after surgery. The number of NPOBCs was also lower in the TIVA group [median 5, interquartile range (IQR) 2 to 10] than in the S group (median 22, IQR 10 to 32) (P < 0.001). The overall number of NPOBCs within PHBQ subscales was significantly lower in the TIVA group than in the S group. The largest difference in the number of NPOBCs between groups was observed for the separation anxiety subscale (mean 5, 95% CI 1 to 9 ; P < 0.001) followed by the general anxiety subscale (mean 4, 95% CI 3 to 5 ; P < 0.001) and apathy/withdrawal subscale (mean 3, 95% CI 1 to 5 ; P < 0.001). CONCLUSION: The prevalence of NPOBC after elective adenotonsillectomy in 6 to 12-year-old children was very high (80%). The choice of anaesthetic technique for adenotonsillectomy in children influenced the incidence and type of NPOBC. Sevoflurane/nitrous oxide anaesthesia was associated with more frequent and prolonged NPOBCs than TIVA, especially in the separation anxiety, general anxiety and withdrawal/apathy subscales.
