Does cardiopulmonary bypass surgery lead to postoperative cognitive impairment?
Does cardiopulmonary bypass surgery lead to postoperative cognitive impairment?
The study highlights that using appropriate statistical models (like split-plot ANOVA) can reveal specific cognitive changes, such as new postoperative attention impairments, following CPB surgery.
Cognitive assessment around CPB may detect at-risk patients; leaves open whether bypass causes new deficits in this observational cohort.
Cognitive decline after cardiopulmonary bypass (CPB) surgery has been a concern since the advent of CPB procedures.A primary focus of many studies on this topic has been to quantify the incidence of post-CPB cognitive impairment.However, studies that have used traditional parametric statistics have generally failed to confirm that long-lasting (Ն 1 month) cognitive declines occur reliably after CPB surgery.For the present study, the authors used a split-plot analysis of variance model that revealed preoperative memory impairments in the CPB patients and new postoperative impairments of attention.The authors discuss the assumptions of, and problems associated with, analysis methods that are often used to quantify the incidence of cognitive impairment following CPB surgery.
