ABSTRACT
Objective To investigate the role of pentose phosphate pathway (PPP) after upper abdominal operationMethods Twenty-six patients undergoing upper abdominal surgery, were divided randomly into three groups: epidural block(EB,n=10), intravenous propofol anesthesia(PRO, n=10) and intravenous procaine balanced anesthesia(IPBA,n=6) The venous blood samples were collected to measure of erythrocytes hexokinase (HK), phosphofructokinase (PFK) and glucose-6-phasphate dehydrogenase (G-6PD), and activities, and plasma glucose before anesthesia induction, 60 min after incision,60 min after surgery, on the 1st and 2nd postoperative daysResults Compared with the values before anesthesia, the activities of erythrocyte HK and PFK decreased significantly on the 1st postoperative day in three groups (P
