Changes in serum mannose‐binding lectin (MBL) level 30 min after weaning from cardiopulmonary bypass (CPB) (ratio MBL2/1) in relation to postoperative complications*.

Complication	Yes	No	P
Infection	0·65	0·78	0·62
SIRS	0·58	0·82	0·03
LCOS	0·82	0·77	0·35
Renal insufficiency	0·79	0·77	0·74
Liver dysfunction	0·58	0·78	0·63
MODS	0·78	0·77	0·91

^a*Decreases in serum MBL are expressed as the median ratio of values obtained at 30 min post‐bypass to the preoperative values (MBL‐2/MBL‐1). Only patients with preoperative values > 100 ng/ml were included. The significance of the differences was determined by the Mann–Whitney U‐test. LCOS = low cardiac output syndrome; MODS = multiple organ dysfunction syndrome.
