摘要
Abstract
Objective To compare the myocardial protective effects with different perfusion pressures of retrograde coronary sinus perfusion. Methods 60 cases suffering from bivalvular replacement were divided into 2 groups randomly, 30 cases for each group. Every patient was introduced to the myocardial preservation technique of primary aortic root antegrade perfusion combined with secondary retrograde coronary sinus perfusion. The retrograde perfusion pressure in group A was (30 ±2) mm Hg, and (40 ±2) mm Hg in group B. Different myocardial protective effects between these two groups were compared. Results Comparing to group A, the patients in group B had fewer dopamine usage and shorter mechanical ventilation time (P < 0. 05), and the results of CKMB, cTn -I and LDH were obviously lower. Only one patient had presented the low cardiac output syndrome in group A. Conclusion The retrograde perfusion pressure of 40 mm Hg can induce better myocardial protective effect than 30 mmHg.关键词
