Protective effect of hyaluronidase after long-term aortic cross- clamping: initial experimental observations
D Vij, LH Toledo-Pereyra, DJ Magilligan Jr and FM Jara
This work studies the effect of hyaluronidase on myocardium subjected to
long-term aortic cross-clamping (three hours) and moderate hypothermia (28
degrees C). Animals receiving hyaluronidase (1,00o U per liter) through the
root of the aorta with a procaine-potassium chloride-lasmalyte cardioplegic
solution showed better functional, electrical, and morphological response
than the untreated animals. These findings, although preliminary, appear to
be promising for potential clinical application.
