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.
ABSTRACT
Objective@#To investigate the prevalence characters of peripheral artery disease (PAD) and associated factors among people aged 35 and above in Beijing.@*Methods@#This was a cross-sectional study. A total of 5 208 community-based individuals aged equal and above 35 in Beijing were chosen with stratified multistage random sampling method. Structure questionnaire was used to collected the information of demographic factors, habits and chronic disease history. Ankle brachial blood pressure was detected and ankle brachial index (ABI) was calculated. ABI was used to diagnose PAD (ABI≤0.90). Based on the 2010 Beijing Municipal Population Census, the age-and gender-specific weight-adjusted sample was acquired to estimate the prevalence of PAD and corresponding 95% confidence intervals (CI). Multivariate logistic regression analysis was performed to estimate the associated factors of PAD.@*Results@#The age-and sex-standardized prevalence of PAD was 3.84% (200/5 208, 95%CI 3.32%-4.36%). There was no significant difference between male and female (3.83%(102/2 664, 95%CI 3.10%-4.56%) vs. 3.85% (98/2 544, 95%CI 3.10%-4.60%), P=0.965). The prevalence of PAD in urban was higher than that in rural (4.34% (163/3 755, 95%CI 3.69%-4.99%) vs. 2.55% (37/1 453, 95%CI 1.74%-3.36%), P=0.001). Furthermore, the prevalence of PAD increased with age (Ptrend<0.01), and the difference between genders did not change with ageing (all P>0.05). In addition, age (OR=1.03, 95%CI 1.01-1.04), urban (OR=1.52, 95%CI 1.08-2.12), smoking (OR=1.83, 95%CI 1.29-2.59), hypertension (OR=1.61, 95%CI 1.17-2.22) and diabetes (OR=1.44, 95%CI 1.08-1.93) were related with increased risk of PAD in logistic regression analysis models.@*Conclusions@#The prevalence of PAD increases with age in Beijing and there are significant difference between urban and rural on prevalence of PAD. Age, urban, smoking, hypertension and diabetes are related with increased risk of PAD.
