Lactate level during cardiopulmonary bypass as a predictor of postoperative outcomes in adult patients undergoing cardiac surgery

JA Clinical Reports

Table 4 Multivariate association of preoperative and intra-operative variables with the ICU-free survival days

Variable	Regression coefficient	p value
Preoperative eGFR	0.086	<0.001*
CPB duration	−0.107	0.278
Preoperative MAP—mean CPB pressure	−0.083	0.015*
Lactate level at CPB-2 h	−3.601	<0.001*

Model R ² = 0.387; data were shown as β regression coefficients
