The aim of our study was a 30-day follow-up of the use of early detection of endotoxin by the endotoxin activity assay (EAA) for patients with acute liver failure superimposed on chronic liver disease (AoCLF) and treated with polymyxin-B hemoperfusion-based (PMX-DHP) treatment and albumin dialysis in the molecular adsorbent recirculating system (MARS). ⋯ The possibility of an early diagnosis using the EAA in AoCLF patients could prevent the progression of the sepsis cascade. The use of PMX-DHP and MARS in these patients, could lead to resolution of clinical status in a short time.

In addition to hepatitis C, hepatocellular carcinoma. is a leading indication for orthotopic liver transplantation (OLT). The indications for OLT in HCC remains a topic of debate. The successful Milan criteria are still accepted as the gold standard to select candidates with a good chance for long-term survival. ⋯ Among items of the Milan criteria tumor size had less impact on outcomes then number of foci. The majority of cases who exceeded the Milan criteria had been transplanted before 2003. Our results suggested that the Milan criteria should be applied for the selection of candidates in order to promise good survival after OLT for HCC.

Assessing adequate volemia to avoid fluid overload and pulmonary edema perioperatively in liver transplantation (LT) is a challenge both for the anesthetist and the intensivist. Volumetric preload indices, such as intrathoracic blood volume index (ITBVI), measured by transpulmonary thermodilution, and continuous end-diastolic volume index (EDVI), measured by pulmonary artery thermodilution, were shown to better reflect preload than central venous pressure (CVP) or pulmonary artery occlusion pressure (PAOP). An ITBVI increase soon after the graft reperfusion influenced pulmonary perfusion without an alteration of extravascular lung water index (EVLWI) and without impaired oxygenation. This study was designed to evaluate relationships between CVP, PAOP, ITBVI, EDVI, and stroke volume index (SVI) within 48 hours after LT. We also investigated the relationship between EVLWI and arterial partial pressure of oxygen and inspired oxygen fraction ratio (PaO(2)/FiO(2)). ⋯ In the first 48 hours after LT, ITBVI and EDVI were associated with SVI assessment, whereas CVP and PAOP were not related. EVLWI significantly inversely correlated with PaO(2)/FiO(2).

Ex vivo lung perfusion (EVLP) has been recently proposed to recondition organs before transplantation from donors with marginal or unacceptable features. The aim of our investigation was to explore glucose consumption during EVLP. ⋯ We found that the worse the lung function, the greater the consumption of glucose during EVLP. This observation suggests the need to explore lung metabolism during EVLP to possibly obtain metrics for evaluation.

It has been shown that anesthetic requirements during liver transplantation are inversely proportional to the degree of hepatic dysfunction. We investigate alterations during the three phases of requirements for intraoperative isoflurane within the target of 40 to 55 Bispectral Index (BIS) values concerning patients with end-stage liver disease who are undergoing liver transplantation. After faculty ethics committee approval, we studied 50 patients of (age range, 18 to 65 years) who were undergoing liver transplantation. ⋯ The ETiso values were lowest in the anhepatic phase compared to other phases, but the differences were not clinically important. The ETiso values in the dissection and neohepatic phases were compared with the anhepatic phase higher 5% and 8.6% respectively. During liver transplantation, ETiso requirement for the anhepatic phase was lower compared with the other two phases within the range of 40 to 55 BIS values.
