Cardiopulmonary arrest in liver transplantation surgery: Perioperative beta-blockade implication in the cirrhotic patient.

Liver transplantation (LT) has an incidence of intraoperative cardiopulmonary arrest (CPA) of around 5%. Patients who experience CPA during this procedure have a reduced survival rate of approximately 50%. Most CPAs occur during the neohepatic phase due to reperfusion syndrome, but this is not always the underlying cause, and a broad differential diagnosis must be performed.

Dynamics of Ischemia/Reperfusion Injury Markers During Normothermic Liver Machine Perfusion.

Background: A comprehensive mechanistic assessment of normothermic machine perfusion (NMP) is an essential step toward identifying biomarkers to assess liver viability. Although some studies have evaluated the effect of NMP on inflammation markers, there are other key pathological mechanisms involved in ischemia/reperfusion injury (IRI) that have not yet been evaluated.

Methods: Eight human donor livers preserved by NMP were included to analyze IRI during preservation.

Demographic Trends in Liver Transplant Survivors After 3 Decades of Program Implementation: The Impact of Cohort and Period Effects on Life Expectancy.

Background: Demographic analyses may reveal current patterns of change in the outcomes of rapidly developing medical procedures because they incorporate the period perspective.

Methods: We analyzed the changes in size, age structure, and hospitalizations in the population of liver transplantation (LT) survivors in our center during the last 30 y (n = 1114 patients) and generated projections, including life expectancy (LE), considering cohort and period effects. Life tables were used to project the complete LE (overall 1990-2020 experience), the cohort LE (according to the decade of surgery: 1990-2000, 2000-2010, and 2010-2020), and the period LE (current 2015-2020 experience).

The link between high factor VIII to protein C ratio values and poor liver function after major hepatectomy.

Our goal was to assess the coagulation profile in the immediate postoperative time after major liver surgery and its association with the liver function. Our hypothesis is that a decreased synthesis of the coagulation factor levels reflects an impaired liver synthesis following hepatic resection and will be associated with poor outcomes. This is a prospective, observational study recruiting consecutive patients scheduled for major liver resection in a tertiary hospital.

An Individualized Low-Pneumoperitoneum-Pressure Strategy May Prevent a Reduction in Liver Perfusion during Colorectal Laparoscopic Surgery.

High intra-abdominal pressure (IAP) during laparoscopic surgery is associated with reduced splanchnic blood flow. It is uncertain whether a low IAP prevents this reduction. We assessed the effect of an individualized low-pneumoperitoneum-pressure strategy on liver perfusion.
