Effects of combined general and epidural anesthesia on intestinal barrier function after obstructive jaun-dice surgery / 临床麻醉学杂志

ABSTRACT

Objective To investigate the effects of combined general and epidural anesthesia on intestinal barrier function in patients with obstructive jaundice after surgery.Methods Forty patients with obstructive jaundice,male 1 5 cases,female 25 cases,aged 26-65 years,of ASA Ⅰ-Ⅲ,with TBIL >100 μmol/L were randomly divided into two groups (n =20)the general intravenous anes-thesia group (group GA)and the combined general and epidural anesthesia group (group GE).Pa-tients of group GA with oxygen mask rapid intubate induction of endotracheal after general anesthesia. Patients of group GE take left side line of T8~9 or T9 ~1 0 segmental epidural puncture and insert cathe-ter,after changing the hypothesis to be 2% lidocaine 5 ml for test quantity,confirm without anesthe-sia complications and other abnormalities after general anesthesia 5 minutes later.Peripheral venous blood was sampled when entering the operating room (T1 ),and at the end of operation (T2 ),24 hours after operation(T3 )and 48 hours after operation (T4 ).The concentration of D-lactate (D-LA) was measured using ELISA method.Also polymerase chain reaction (PCR)was performed for quali-tative detection of Escherichia coli specific beta galactosidase gene BG.Results Compared with T1 , Plasma D-LA level in two groups at T2-T4 were increased gradually and it was significantly higher in group GA than in group GE at T2-T4 with significant difference (P <0.05).The Escherichia coli DNA test was negative at T1 ,the positive rate of Escherichia coli DNA gradually increased,and it was significantly higher in group GA than in group GE at T4 with significant difference(P <0.05).Conclusion Compared with the general intravenous anesthesia, general anesthesia combined with epidural anesthesia may relieve the intestinal barrier injury in patients with obstructive jaundice after surgery.
