Abstract: Objective

To investigate the changes in the levels of serum neuron specific enolase (NSE) and serum S-100β protein during the perioperative period in the infants underwent parent liver transplantation, and to clarify the relationships between NSE, S-100β and brain injury during the perioperative period of the infants underwent parent liver transplantation.

Methods

Forty infants with congenital biliary atresia underwent parent liver transplantation were selected, aged 4-12 months, weighing 3.0-10.0 kg, ASA status Ⅲ or Ⅳ class. The blood samples were drawn from central vein of the infants before skin incision (T1), 30 min after anhepatic phase (T2), 1 h after neohepatic phase (T3) and 24 h after neohepatic stage (T4). Furthermore, the heart rate (HR), the mean arterial blood pressure(MAP), the central venous pressure(CVP),and pH values of blood were monitored at the moments of T1-T 4. The serum S-100β and NSE levels were detected by ELISA method.

Results

The levels of hemodynamics were significantly changed in anhepatic phase and neohepatic phase;compared with T1,the HR at T2 of the infants was accelerated (P<0.05),and the MAP, CVP and pH value of blood were decreased (P<0.05). After the surgery, all the hemodynamic indexes fell to the preoperative levels. Compared with T1, the serum NSE and S-100β levels at T2-T 4 of the infants were decreased (P<0.05); compared with T2, the serum S-100β and NSE levels of the infants at T3 of the infants were significantly increased (P<0.05); compared with T3,the serum S-100β and NSE levels at T4 of the infants were significantly decreased (P<0.05).

Conclusion

The brain injury may appear during the perioperative in the infants underwent parent liver transplantation and gradually aggravates during the anhepatic phase and gradually returns to the preoperative levels at 24 h after surgery.
