Background: The efficacy and feasibility of bilateral subthalamic deep brain stimulation (STN-DBS) for Parkinson’s disease (PD) under general anesthesia (GA) has not been evaluated. Objective: We compared the outcome of patients under GA with those who were operated on under local anesthesia (LA). Material and Methods: Thirty-three patients were assigned to the GA group (desflurane) and 19 patients were assigned to the LA group. Microelectrode recording (MER) was performed in both groups. The surgical outcomes of the patients were evaluated using the Unified Parkinson’s Disease Rating Scale (UPDRS) after at least 12 months after surgery. Results: Postoperatively, there was no significant difference on the UPDRS scores in either groups. A significant deterioration in cognitive function in the GA group was observed (p = 0.017). The recorded electrode coordinates, the average tracts for the MER, and STN depth were comparable in both groups. The overall incidence of adverse effects did not show any difference except that the incidence of sialorrhea and dysarthria was significantly higher in the GA group. Conclusion: Desflurane GA was shown to be a good alternative anesthetic method for PD patients undergoing DBS. Although the motor outcomes were comparable, a significant cognitive decline may be seen in the GA group with a higher occurrence of stimulation side effects.

Dysphagia following neurological impairment increases the risk of dehydration, malnutrition, aspiration pneumonia, and even death. Screening for dysphagia has been reported to change negative outcomes. This review evaluated the validity and reliability of measurement tools for screening dysphagia in patients with neurological disorders to identify a feasible tool that can be used by nurses. Electronic databases were searched for studies from 1992 to 2015 related to dysphagia screening measurements. The search was applied to the Pubmed, CINAHL, Cochrane, Medline, EBSCO host, and CEPS + CETD databases. A checklist was used to evaluate the psychometric quality. The tools were evaluated for their feasibility for incorporation into routine care by nurses in hospitals. A total of 104 papers were retrieved, and eight articles finally met the inclusion criteria. The sensitivity and specificity of the screening tools ranged from 29% to 100% and from 65% to 100%, respectively. The interrater reliability ranged from good to excellent agreement. On the basis of quality evaluations, all the included studies had a risk of bias because of inadequate methodological characteristics. The Standardized Swallowing Assessment is the most suitable tool for detecting dysphagia because its psychometric properties and feasibility are higher than those of other screening tools that can be administered by nurses.
