Central venous catheterization is widely used for various purposes during surgery. For central venous catheterization, subclavian vein is selected because of the relatively low risk of infection, long-term patency and low patient discomfort. The cross - sectional area of the subclavian vein is an important factor to increase success rate. Several studies have reported that the Trendelenburg position increases the cross-sectional area of the subclavian vein, and the lateral tilt position can change the cross-sectional area of the subclavian vein. However, the impact of lateral tilt position to the cross-sectional area of the subclavian vein is not clear. The ipsilateral position can increase the cross-sectional area of the subclavian vein, and the contralateral position can decrease the cross-sectional area by gravity.
In the second stage of this study, the investigators would like to compare the success rate, the number of needle passage, time to complete subclavian vein catheterization in supine and ipsilateral tile position.

Assessment of Intermittent Self-Catheterization Procedures in Patients with Neurogenic Lower Urinary Tract Dysfunction: Dutch Translation and Validation of the Intermittent Catheterization Satisfaction Questionnaire, Intermittent Catheterization Acceptance Test, Intermittent Self Catheterization Questionnaire and Intermittent Catheterization Difficulty Questionnaire.
Intermittent self-catheterization (ISC) is by far the most appealing therapy to achieve a complete bladder emptying in patients with neurogenic lower urinary tract dysfunction (NLUTD). Four questionna...
Although vestibular inputs are bilaterally represented within the cerebral hemispheres, the higher level vestibular functions exhibit hemispheric asymmetries. Previous studies have suggested that such...
The kinetic link among the lumbar spine, pelvic tilt, and the hip has been hypothesized, but this relationship requires further study in acetabular dysplasia. Anecdotal reports suggest that patients m...

INFARCTION of the dorsolateral aspect of MEDULLA OBLONGATA in the BRAIN STEM. It is caused by occlusion of the VERTEBRAL ARTERY and/or the posterior inferior cerebellar artery. Clinical manifestations vary with the size of infarction, but may include loss of pain and temperature sensation in the ipsilateral face and contralateral body below the chin; ipsilateral HORNER SYNDROME; ipsilateral ATAXIA; DYSARTHRIA; VERTIGO; nausea, hiccup; dysphagia; and VOCAL CORD PARALYSIS. (From Adams et al., Principles of Neurology, 6th ed, p801)
A syndrome associated with injury to the lateral half of the spinal cord. The condition is characterized by the following clinical features (which are found below the level of the lesion): contralateral hemisensory anesthesia to pain and temperature, ipsilateral loss of propioception, and ipsilateral motor paralysis. Tactile sensation is generally spared. (From Adams et al., Principles of Neurology, 6th ed, p162).
Posture while lying with the head lower than the rest of the body. Extended time in this position is associated with temporary physiologic disturbances.
A standard and widely accepted diagnostic test used to identify patients who have a vasodepressive and/or cardioinhibitory response as a cause of syncope. (From Braunwald, Heart Disease, 7th ed)
