The liver is currently considered to be one of the first organs to be subjected to the hypoxic insult inflicted by hemorrhagic shock. The oxidative injury caused by resuscitation also targets the liver and can lead to malfunction and the eventual failure of this organ. Each of the various fluids, vasoactive drugs, and pharmacologic substances used for resuscitation has its own distinct effect(s) on the liver, and the anesthetic agents used during surgical resuscitation also have an impact on hepatocytes. The aim of our study was to identify the specific effect of these substances on the liver. To this end, we conducted a literature search of MEDLINE for all types of articles published in English, with a focus on articles published in the last 12 years. Our search terms were "hemorrhagic shock," "liver," "resuscitation," "vasopressors," and "anesthesia." Experimental studies form the majority of articles found in bibliographic databases. The effect of a specific resuscitation agent on the liver is assessed mainly by measuring apoptotic pathway regulators and inflammation-induced indicators. Apart from a wide range of pharmacological substances, modifications of Ringer's Lactate, colloids, and pyruvate provide protection to the liver after hemorrhage and resuscitation. In this setting, it is of paramount importance that the treating physician recognize those agents that may attenuate liver injury and avoid using those which inflict additional damage.
Hydatidosis is a usually asymptomatic chronic disease. In most patients who undergo surgery, hydatidosis is not resolved due to high recurrence rate. However, long-term treatment with albendazole has been found to have a significant efficacy that has been further improved when albendazole is combined with praziquantel and fat-rich diet. In this study a retrospective evaluation of the outcome of hydatidosis in 70 patients, was performed. In group A, a combined chemotherapy of albendazole plus praziquantel was given after surgical removal of cysts. In group B chemotherapy alone was administered without surgery. Sera of all patients were assayed for IgG, IgM, IgA and IgE antibodies by ELISA. In addition, ultrasonography (US) and/or computerized tomography (CT) scans were performed every 3 months for 18 months, and then, each year until the end of follow-up. The difference between the two kinds of treatment used in the present study was found to be not significant, nor was the difference of the shrinkage and extended calcification of the HCs between the two groups. However, the difference of the shrinkage of the HCs of more than 80%, as well as the extended calcifications of the cysts between the two groups were found to be statistically significant. In all patients high levels of IgG and IgA were detected, while IgE in group A and/or IgM in group B were marginally detected above the background level throughout the study. Level of IgG was strongly fluctuated and significantly decreased at 11.7 years after the end of chemotherapy, or at 8.5 years after relapses in group A, while was dramatically decreased at 3.6 years after the termination of chemotherapy in group B. Relapses occurred in 11.4% of patients within the first six months after end of chemotherapy. After additional chemotherapy with albendazole for 3–6 months, all of them were considered cured at 8.5 years of follow up.
Our experimental study showed that coadministration of NAC and DFO during liver hemorrhage can decrease the amounts of fluids needed for resuscitation. Moreover, the antioxidant combination restores the energy dependent apoptosis and proliferation of the hepatocytes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
