ABSTRACT
Objective:
To evaluate the effect of inhalation of sevoflurane during cardiopulmonary bypass (CPB) on early postoperative brain injury in the patients undergoing cardiac valve replacement.Methods:
Forty-two American Society of Anesthesiaologists physical status Ⅱ or Ⅲ patients of either sex, aged 40-70 yr, weighing 47-86 kg, scheduled for elective single valve replacement under CPB, were divided into 3 groups ( n=14 each) using a random number tablemethod:
control group (group C), combined intravenous-inhalational anesthesia group (group CA) and sevoflurane group (group S). During CPB, propofol 4-6 mg·kg -1·h -1 was intravenously infused in group C, propofol 2-3 mg·kg -1·h -1 was intravenously infused, and 0.5 MAC sevoflurane was inhaled via the membrane oxygenator in group CA, and 1.0-1.5 MAC sevoflurane was inhaled via the membrane oxygenator in group S. The anesthesia and sedation index values were maintained at 40-60 during operation in the three groups.Blood samples were taken from arteries before anesthesia induction (T 1), at 30 min and 6 and 24 h after termination of CPB (T 2-4) for determination of plasma concentrations of neuron-specific enolase (NSE) and Tau protein.Results:
Compared with group C, the plasma concentration of NSE was significantly decreased at T 2, 3, and plasma concentration of Tau protein was decreased at T 2-4 in group S, and the plasma concentration of Tau protein was decreased at T 2 in group CA ( P<0.05). Compared with group CA, the plasma concentration of NSE was significantly decreased at T 2, 3, and the plasma concentration of Tau protein was decreased at T 2-4 in group S ( P<0.05).Conclusions:
Inhalation of sevoflurane during CPB can reduce early postoperative brain injury to a certain extent in the patients undergoing cardiac valve replacement.
