A simple technique for retrograde cerebral perfusion during circulatory arrest.

We describe a simple and safe technique for achieving retrograde cerebral perfusion via a small coronary sinus type catheter placed in the superior vena cava. This method is especially useful when the need for circulatory arrest is first recognized intraoperatively and a single two-stage venous cannula has already been placed for cardiopulmonary bypass. The advantages of this technique over other currently employed methods for retrograde cerebral perfusion are discussed.

The content was determined of polychlorinated pesticides in samples of internal organs obtained during autopsy: liver, heart, adrenals in 25 dying patients. The content of gamma-HGH, DDT and DDT metabolites was determined by gas chromatography. The obtained results expressing the content of pesticides and their metabolites in mg/kg of the tissues were analysed statistically using Wilcoxon's rank summation test.
