Analysis of Cumulative Fluid Balance Impact on the Stability of Gastrointestinal Tract Anastomosis.

Anastomotic leakage is a serious postoperative complication following a low anterior resection of rectum. Current research in colorectal surgery focuses on searching for techniques which could minimize the risk of leakage. The main objective of this study was to evaluate the impact of cumulative fluid balance on microcirculatory changes at the anastomotic site.

Lung Collapse during Mini-Thoracotomy Reduces Penetration of Cefuroxime to the Tissue: Interstitial Microdialysis Study in Animal Models.

Single-lung ventilation facilitates surgical exposure during minimally invasive cardiac surgery. However, a deeper knowledge of antibiotic distribution within a collapsed lung is necessary for effective antibiotic prophylaxis of pneumonia. The pharmacokinetics/pharmacodynamics (PK/PD) of cefuroxime were compared between the plasma and interstitial fluid (ISF) of collapsed and ventilated lungs in 10 anesthetized pigs, which were ventilated through a double-lumen endotracheal cannula.

Iron Oxide and Iron Sulfide Films Prepared for Dye-Sensitized Solar Cells.

In this paper, the prospects of iron oxide films and their sulfidation for dye-sensitized solar cells (DSSC) are reviewed. Iron oxide thin films were prepared by hollow cathode plasma jet (HCPJ) sputtering, with an admixture of oxygen in the argon working gas and with an iron nozzle as the sputtering target. The discharge was powered by a constant current source in continuous mode and by a constant voltage source in pulsed mode.

Inhalation of molecular hydrogen prevents ischemia-reperfusion liver damage during major liver resection.

Background: Liver resection is a surgical procedure associated with a high risk of hepatic failure that can be fatal. One of the key mechanisms involves ischemia-reperfusion damage. Building on the well-known positive effects of hydrogen at mitigating this damage, the goal of this work was to demonstrate the antioxidant, anti-inflammatory, and anti-apoptotic effects of inhaled hydrogen in domestic pigs during major liver resection.

Effect of short-term administration of lipid emulsion on endothelial glycocalyx integrity in ICU patients - A microvascular and biochemical pilot study.

Background: Endothelial glycocalyx (EG) is a carbohydrate-rich vascular lining of the apical surface of endothelial cells. It has been proved to have an essential role in vascular homeostasis. Lipid emulsions as part of parenteral nutrition (PN) are widely used in patients in the setting of critical care and perioperative medicine.
