Physicians and other advanced medical personnel commonly perform subclavian vein cannulation. Success depends on adequate knowledge of the anatomy. With this knowledge subclavian vein cannulation can be performed with low complication rates. The manuscript reviews the anatomy and the literature of subclavian vein cannulation.

Admission preoperative glucose is predictive of morbidity and mortality in trauma patients who require immediate operative intervention.
Although there have been reports in the surgical literature regarding the negative effects of preoperative hyperglycemia on outcome, the impact of elevated preoperative serum glucose levels in trauma patients is unknown. Our objectives were to determine whether preoperative hyperglycemia was associated with a greater morbidity and mortality in trauma patients who underwent surgical intervention upon admission. Prospective data was collected on 252 consecutive nondiabetic trauma patients admitted for > or =3 days who went directly to the OR from the resuscitation area. ⋯ Patients with elevated serum glucose had a significantly greater incidence of infection, HLOS, ILOS, and mortality matched per age and ISS. Elevated serum glucose on admission is an accurate predictor of postoperative infection, HLOS, ILOS, and mortality. A randomized prospective trial evaluating the impact of preoperative glucose control is warranted.

Effects of pneumatic dilation and myotomy on esophageal function and morphology in patients with achalasia.
Only two treatment modalities-pneumatic dilation and Heller myotomy-promise long-term relief from dysphagia and regurgitation in patients with achalasia. The objective of this study was to determine whether both options differ in their effects on esophageal function, morphology, and improvement in symptoms. Eighty-nine patients diagnosed with achalasia between January 1980 and December 2002 at a single center were enrolled in this study. ⋯ Morphologic changes, assessed by the diameter of the esophageal corpus, were also more pronounced after surgical therapy (P > 0.05). Both options will lead to an immediate and significant improvement in symptoms, although the two treatment modalities did not differ in their subjective results. As only objective findings, such as those obtained by manometry and the timed barium swallow, have proven relevance for the assessment of long-term results, surgical therapy is the superior and more effective treatment option in patients with achalasia.
