Abstract:
The medical records of patients of both sexes with sleep disorders treated with multimodal sleep therapy for which patient controlled sleep with dexmedetomidine was the main method, aged≥18 yr, with body mass index of 18-30 kg/m 2, from February 2019 to January 2021, were collected.Dexmedetomidine 60 ml/h (4 μg/ml) was intravenously infused until non-rapid eye movement (NREM) Ⅲ phase was reached or the consumption of dexmedetomidine reached 1 μg/kg.Whether dexmedetomidine induced restless legs syndrome (RLS) was judged according to the Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition). When the titration was stopped and on the next day after emergence from anesthesia, clinical diagnosis was performed according to Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition) to determine whether RLS was combined or not.Kappa consistency analysis was used to assess the consistency between dexmedetomidine titration and the Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 Edition) in diagnosis of RLS.The sensitivity and specificity of diagnosis of RLS by dexmedetomidine titration were calculated.A total of 39 patients were included and 8 patients had RLS symptoms which were judged accroding to dexmedetomidine titration.The results of Kappa consistency test showed that there was a strong consistency between dexmedetomidine titration and Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition) (Kappa value 1.0, P<0.01). The sensitivity and specificity of dexmedetomidine titration in judging RLS were 100%.In conclusion, dexmedetomidine titration can accurately judge RLS.
