Effect of ischemic preconditioning under hepatic inflow occlusion on the SGPT levels of domestic cats undergoing right hepatic lobectomy

ABSTRACT

OBJECTIVE: This controlled study was done to determine the protective effects of ischemic preconditioning (IP) on the liver of cats undergoing major liver resection.SPECIFIC OBJECTIVE: To determine the effect of IP on alanine transaminase (ALT or SGPT) in cat*that will undergo major liver resection.DESIGN: This study is a randomized controlled trial.SETTING: LIST Health Sciences Research Laboratory.PATIENTS/ PARTICIPANTS: This is an experimental study on the effects of ischemic preconditioning under hepatic inflow occlusion on the SGPT as a measure of morbidity in Felis catus (domestic cats) undergoing right hepatic lobectomy. Nine male cats, weighing 2.5-5kg, are equally allocated into any one of the following 3 study groups Control group not subjected to ischemic preconditioning (C), Experimental group subjected to 1 1/2 minutes of ischemia followed by 1.5 minutes of reperfusion (El), Experimental group subjected to 5 minutes of ischemia followed by 5 minutes of reperfusion (E2).RESULTS: There was no significant difference in the mean weight of cats in the 3 groups (p = 1.00). Comparing the pre and post result between using paired t-test, there was no significant difference in the baseline values (p = 0.14). However, there was a significant difference in the post result between the three groups (p CONCLUSION: In the past few years, interesting new data on the presence of ischemic preconditioning in various organs as an endogenous means to protect itself from ischemiahas been available. This study investigated and suggests that ischemic preconditioning may provide protection to the liver undergoing hepatic lobectomy.
