Delayed onset of hemothorax: an unusual complication of subclavian access for hemodialysis.

Subclavian catheterization for acute hemodialysis has become routine in many institutions. Immediate complications of this technique are dramatic and easily recognized, whereas late complications are less common, frequently insidious and tend to be more severe. We report the delayed occurrence of a right hemothorax following two hemodialysis treatments with a left subclavian access.

Diagnostic strategies in disorders of fluid, electrolyte and acid-base homeostasis.

Our understanding of the physiology and biochemistry of acid-base and fluid-electrolyte regulations has greatly expanded in recent years. Key physiologic principles have emerged that now permit rational diagnosis and therapy of clinical disorders of serum electrolyte concentration. This paper describes diagnostic strategies based upon these principles.
