Abstract:
Objective To investigate the effect of ulinastatin on the renal function during perioperative period in infants undergoing open heart surgery under CPB.Methods Forty ASA Ⅱ infants (25 male, 15 female)aged 3-5 months weighing 5.3-6.8 kg undergoing open heart surgery under CPB were randomly divided into 2 groups (n = 20 each): control group (group C) and ulinastatin group (group U). Ulinastatin 20 000 U/kg in normal saline 20 ml was infused iv in 3 parts (1/3 was infused via CVP line when the catheter was successfully placed in the internal jugular vein; 1/3 at the beginning of CPB and 1/3 at aortic unclamping). Blood and urine samples were collected at 30 min before incision ( T1 ), 5 min before aortic clamping (T2 ), 5 min after aortic unclamping (T3 ), at the end of operation (T4) and 24 and 48 h after operation (T5, T6 ) for determination of serum urea nitrogen (BUN) and creatinine (Cr) and urinary N-acetyl-β-D-glucosaminidase (NAG) and β2-microglubin (β2-MG) levels. Results There was no significant difference in serum BUN and Cr concentrations between the two groups. The urinary β2-MG concentration and NAG activity were significantly increased at T2-6 as compared with baseline values at T1 in both groups. The urinary β2-MG concentration and NAG activity were significantly lower in group U than in group C at T3-5 . Conclusion Ulinastatin can protect the renal function during perioperative period in infants undergoing open heart surgery under CPB.
