Coronary artery bypass grafting on the cardiopulmonary bypass machine and depression.

摘要

This descriptive exploratory study was designed to identify possible links between the cardiopulmonary bypass machine used for coronary artery bypass grafting surgery and depression. Betty Neumans' Systems Model (1995) provided the theoretical framework. Administration of the Beck II depression tool was done to measure depression in two categories of subjects, those who had CABG on a cardiopulmonary bypass machine and those who had CABG off cardiopulmonary bypass machines. Subjects were given a depression-screening test upon admission into a cardiac rehabilitation setting. Analysis of data revealed that there was no statistical difference in the degree of depression between the two groups. The data did suggest that further study using a larger sample was indicated.
