RESUMEN
The GlideScope® videolaryngoscope (GVL) is widely used in patients with difficult airways and provides a good glottic view. However, the acute angle of the blade can make insertion and advancement of an endotracheal tube (ETT) more difficult than direct laryngoscopy, and the use of a stylet is recommended. This randomized controlled trial compared Parker Flex-It™ stylet (PFS) with GlideRite® rigid stylet (GRS) to facilitate intubation with the GVL in simulated difficult intubations. Methods: Fifty-four patients were randomly allocated to undergo GVL intubation using either GRS (GRS group) or PFS (PFS group). The total intubation time (TIT), 100-mm visual analog scale (VAS) for ease of intubation, success rate at the first attempt, use of laryngeal manipulation, tube advancement rate by assistant, and complications were recorded. Results: There was no significant difference between the GRS and PFS groups regarding TIT (50.3 ± 12.0 s in the GRS group and 57.8 ± 18.8 s in the PFS group, P = 0.108). However, intubation was more difficult in the PFS group than in the GRS group according to VAS score (P = 0.011). Cases in which the ETT was advanced from the stylet by an assistant, were more frequent in the GRS group than in the PFS group (P = 0.002). The overall incidence of possible complications was not significantly different. Conclusions: In patients with a simulated difficult airway, there was no difference in TIT using either the PFS or GRS. However, endotracheal intubation with PFS is more difficult to perform than GRS.
RESUMEN
PURPOSE: Dyslipidemia, hypertension, and diabetes are well-established risk factors for cardiovascular disease (CVD). This study investigated the prevalence and management status of these factors for dyslipidemia among Korean adults aged 30 years old and older. MATERIALS AND METHODS: The prevalence and management status of dyslipidemia, hypertension, and diabetes were analyzed among 12229 subjects (≥30 years) participating in the Korea National Health and Nutrition Survey 2010–2012. Dyslipidemia was defined according to treatment criteria rather than diagnostic criteria in Korea. Therefore, hyper-low-density lipoprotein (LDL) cholesterolemia was defined if LDL cholesterol levels exceeded the appropriate risk-based threshold established by the National Cholesterol Education Program Adult Treatment Panel III. RESULTS: The age-standardized prevalence was highest for dyslipidemia (39.6%), followed by hypertension (32.8%) and diabetes (9.8%). The lowest patient awareness was found for dyslipidemia (27.9%). The treatment rate was 66.5% for diabetes and 57.3% for hypertension, but only 15.7% for dyslipidemia. The control rate among those undergoing treatment was highest for hypertension (64.2%), followed by dyslipidemia (59.2%) and diabetes (22.1%). The higher the risk levels of CVD were, the lower the control rate of dyslipidemia. CONCLUSION: While the prevalence of dyslipidemia was higher than hypertension and diabetes, awareness and treatment rates thereof were lower. Higher CVD-risk categories showed lower control rates of dyslipidemia. In order to improve awareness and control rates of dyslipidemia, diagnostic criteria should be reconciled with treatment targets based on cardiovascular risk in Korean populations.
