Abstract
BACKGROUND: Propofol has been reported to provide protection against ischemia–reperfusion injury. Nuclear transcription factor kappa B (NF
B) plays a key role in oxidative stress and the inflammatory response during ischemia–reperfusion. We compared the effect of propofol with sevoflurane on kidney NF
B expression and systemic inflammatory responses induced by aortic clamping.
METHODS: Twenty piglets were divided into four groups: sham surgery group with propofol (group SP, n = 5); sham group with sevoflurane (group SS, n = 5); and suprarenal clamping for 30 min with aorta–aortic bypass under propofol (group CP, n = 5) or sevoflurane (group CS, n = 5) anesthesia. Propofol was administered at 4 mg · kg–1 · h–1 IV and sevoflurane given at 1.5% inspiratory concentration. Peripheral blood and kidney biopsies were taken before the start of surgery, 15 min after unclamping the aorta, 24, 48, 72 h, and 7 days after surgery. Plasma creatinine, myeloperoxidase, tumor necrosis factor-
, interleukin 1-β; and kidney superoxide anion and superoxidase dismutase were measured. The expression of inducible nitric oxide synthase and renal tissue NF
B was measured using Western blotting.
RESULTS: Compared with the CS group, animals in the CP group had lower concentrations of myeloperoxidase, tumor necrosis factor-
, interleukin 1β, superoxide anion, superoxidase dismutase (P < 0.05) from 24 to 72 h after surgery and diminished NF
B expression and inducible nitric oxide synthase activity (P < 0.05) at 48 and 72 h after surgery, respectively.
CONCLUSIONS: Compared with sevoflurane, propofol administration during suprarenal aortic clamping and unclamping led to modulation of markers of inflammation and decreased NF
B expression.
