简要总结
The aim of this study is to evaluate hepatoprotective effect from ischemia-reperfusion injury of remote ischemic preconditioning of the liver against local ischemic preconditioning of the liver during human liver resections.
详细描述
In this randomized control study, a total of 60 patients were randomized into 3 groups: remote ischemic precondition group - RIPC (3 intervals of 5 minute right upper limb ischemia with 3 intervals of 5 minute reperfusion), local ischemic precondition group - LIPC (15 minutes of inflow liver occlusion followed by 10 minutes of reperfusion before liver transection), control group - CG (group without ischemic preconditioning before liver transection). Patients were also stratified according to the extent of the hepatectomy. Hepatoprotective effect was evaluated by comparing serum transaminase levels, bilirubin levels, albumin, and protein levels, coagulograms and pathohistological exams. We also measured flow rate by Doppler ultrasound of hepatic artery and portal vein before and after preconditioning.

结局指标
主要结局
Change in synthetic liver function
时间窗: Preoperatively, first, third and seventh postoperative day
We measured residual synthetic liver function and liver ischemic-reperfusion injury by value level of bilirubin, total proteins, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutamic aminotransferase (ƴGT), cholinesterase, alkaline phosphatase (AP), coagulogram.
次要结局
- Flow through the hepatic artery and portal vein(Before and after preconditioning)
- Liver histology evaluation(Up to 10 days after operation)
