This report evaluates the effects of NAC on liver perfusion and lactate signal intensities in the liver tissue of septic shock patients using proton magnetic resonance imaging and spectroscopy. kFurthermore, the monoethylglycinexylidide (MEGX) test was used to investigate hepatic function. Methods: Five septic shock patients received 150 mg/kg body weight NAC as an intravenous bolus injection over 15 min. Lidocaine was injected both prior to and following NAC administration in order to determine MEGX formation. Measurements (hemodynamics, oxygen transport-related variables, blood samples for lactate, liver-related markers) were performed 1 hour before and 1 hour after NAC injection. In addition to the proton magnetic resonance imaging patients received two proton magnetic resonance spectra, one prior to and one 30 min subsequent to the onset of the NAC infusion at a 1.5 Tesla clinical scanner, for measurement of liver perfusion and liver lactate signal intensity. Main findings: Following NAC infusion, the lactate signal intensity in the liver tissue showed a median decrease of 89% (1199%), there was a median increase in liver perfusion of 41% (-14 to 559%), and the MEGX serum concentration increased three times (1.525.91)."],["dc.format.mimetype","application/pdf"],["dc.identifier.ppn","526364726"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?goescholar/1266"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60826"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.rights","Goescholar"],["dc.rights.access","openAccess"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject","Klinische Pathologie; Urologie"],["dc.subject.ddc","610"],["dc.subject.ddc","616.07"],["dc.subject.ddc","616.6"],["dc.title","N-acetylcysteine decreases lactate signal intensities in liver tissue and improves liver function in septic shock patients, as shown by magnetic resonance spectroscopy: extended case report"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
