Relationship between anesthetic factor and intestinal injury in patients undergoing cardiac surgery with cardiopulmonary bypass: a comparison of propofol-versus sevoflurane-based anesthesia / 中华麻醉学杂志

ABSTRACT

Objective To investigate the relationship between anesthetic factors and intestinal injury in the patients undergoing elective cardiac surgery with cardiopulmonary bypass (CPB).Methods Ninety American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes,aged 18-64 yr,with New York Heart Association grade Ⅱ or Ⅲ,undergoing elective cardiac surgery with CPB,were divided into 2 groups (n =45 each) using a random number table:propofol-based anesthesia group (group P) and sevoflurane-based anesthesia group (group S).CPB was established routinely after anesthesia induction.Before induction (T0),immediately after aortic unclamping (T1),at 30 min after aortic unclamping (T2) and at 2 h after discontinuation of CPB (T3),blood samples were collected from the radial artery for determination of the plasma endotoxin,D-lactic acid,diamine oxidase (DAO) and intestinal fatty acid-binding protein (Ⅰ-FABP) concentrations (by enzyme-linked immunosorbent assay) and plasma interleukin-6 (IL-6),IL-8 and tumor necrosis factor-alpha (TNF-o) concentrations (using radio-immunity method).Results Compared with the baseline at T0,the concentrations of plasma endotoxin,D-lactic acid,DAO,TNF-α,IL-6,IL-8 and I-FABP were significantly increased at T1-T3 in both groups (P＜0.05).Compared with group P,the concentrations of plasma endotoxin,D-lactic acid,DAO,TNF-α,IL-6,IL-8 and I-FABP were significantly decreased at T1-T3 in group S (P＜0.05).Conclusion Anesthetic factors are related to intestinal injury in patients undergoing cardiac surgery with CPB.Compared with propofol-based anesthesia,sevoflurane-based anesthesia is helpful in reducing the inflammatory response and in decreasing the degree of intestinal injury and is more suitable for the cardiac surgery with CPB.
