Table 2 Alkaline phosphatase activity, measured pre-operatively and on post-operative day 1

From: Alkaline phosphatase activity after cardiothoracic surgery in infants and correlation with post-operative support and inflammation: a prospective cohort study

  No CPB CPB DSC P-value No CPB vs. CPB P-value No CPB vs. DSC P-value CPB vs. DSC
AP (U/L), Pre-op 143 (128, 173) 236 (150, 302) 155 (28, 297) < 0.05 ns < 0.005

  1. Alkakine phosphatase (AP) levels are presented as median (25th, 75th percentiles). CPB, cardiopulmonary bypass; DSC, delayed sternal closure; AP, alkaline phosphatase; POD, post-operative day; ns, not significant.
