Zhang Y, et al. - Using a multivariate logistic regression model, researchers examined 80 individuals to analyze the risk factors of early postoperative cognitive dysfunction (POCD) after colorectal surgery. They performed neuropsychological tests of all the candidates before and after the operation. They observed 24.7% of cases with POCD. They noted fasting over 3 days after surgery, a history of diabetes and systemic inflammatory response syndrome (SIRS) score of > 3 on the second day after the operation as the risk factors for early POCD in colorectal cancer cases. Besides, no significant difference was noticed between the POCD and non-POCD groups regarding operation time, bleeding, transfusion, urine, hypotension, delirium, Intensive Care Unit (ICU) stay, or in-hospital stay.
