An Evaluation of the Pericardial Sac as a Safety Factor During Tamponade.

摘要

Studies were conducted in vitro to determine the permeability characteristics of the rabbit and dog pericardium. The hydraulic conductance was significantly higher than other tissue for the rabbit and dog pericardium. The permeability coefficient of the pericardium for the rabbit is provided for water, glucose, and albumin. The reflection coefficient for various solutes is also given. The results, which indicate that the pericardium offers little resistance to the bulk transfer of liquids of the passage of large molecules, are discussed as possible safety factors during pericardial effusion.
