Abnormal peripheral perfusion is defined as at least one abnormal peripheral perfusion variable capillary refill time >4.5 seconds, peripheral perfusion index <1.4 or a forearm-to-fingertip skin temperature gradient >2°C. We used a generalized mixed-model analysis to calculate the predictive value of abnormal peripheral perfusion for severe complications at each postoperative day. Mean arterial pressure, heart rate, vasopressor therapy, C-reactive protein and haemoglobin were used to adjust the predictors in the multivariate analysis. P < 0.017 is considered significant.
