The study, conducted by researchers from the Department of Anaesthesia at St. Vincent’s Health, administered eight neurological tests at baseline and at seven days and three months postoperatively to subjects from three procedure groups and one control group. The study sample consisted of subjects involved in three separate clinical trials: coronary angiography under sedation, major non-cardiac surgery under general anesthesia and coronary artery bypass graft surgery under general anesthesia.
The incidence of POCD in elderly patients seven days after surgery was higher after CABG surgery than THJR surgery, but after three months, there was no difference when comparing the three surgical groups. Cardiovascular risk factors were not predictive of POCD after any procedure.
