Effects of multiple exposures to general anesthesia on the sleep quality of children after plastic surgery in Beijing, China: a cohort study.

Abstract

To assess the effects of the number and duration of general anesthesia exposure on the sleep quality of 6-15-year-old school children who underwent plastic surgery. The study was conducted on 688 children who underwent plastic surgery between the ages of 6 and 15years using the Sleep Disorder Scale for Children (SDSC). The children were divided into two groups according to their exposure to general anesthesia: No General Anesthesia (NGA) and General Anesthesia (GA) groups. The GA group was further divided into three subgroups according to the number of exposures: Single-exposure, Double-exposure, and Multiple-exposure groups. The GA group was also subdivided into two groups according to the cumulative total time of anesthesia exposure: < 3h and ≥ 3h groups. Multivariate logistic regression analysis was used to confirm the potential factors that affect children with sleep disturbance (SDSC scores > 39) after general anesthesia exposure. Linear regression was used to analyze the correlation of the factors with the SDSC scores. The SDSC scores were higher in the GA group [35.4 ± 4.3 vs. 34.0 ± 3.6, P < 0.0001] as compared to the NGA group. The number of children with SDSC scores > 39 was also higher in the GA group [80 (17.5%) vs. 17 (7.4%), P < 0.0001]. More anesthesia exposure was correlated with higher total SDSC scores [34.5 ± 4.3 for single exposure vs 35.1 ± 3.9 for double exposure vs 37.5 ± 4.5 for multiple exposures, P < 0.0001] and a higher proportion of SDSC scores > 39 [24 (12.0%) for single exposure vs 24 (15.5%) for double exposure vs 32 (31.1%) for multiple exposures, P < 0.0001]. Longer anesthesia exposure was also correlated with higher total SDSC scores [34.4 ± 4.5 for < 3h vs. 35.8 ± 4.2 for ≥ 3h, P = 0.002]. The number of exposures to general anesthesia was a potential factor in sleep disturbance among children, determined based on logistic regression. Children who underwent plastic surgery between the ages of 6 and 15years with general anesthesia exposure might have worse sleep quality and a higher incidence of sleep disorders. More frequent anesthesia exposure leads to worsened sleep quality and a higher incidence of sleep disorders. This study also confirmed that a longer duration of cumulative anesthesia exposure also leads to worse sleep quality.
