[Impact of hypotension and global hypoperfusion in postoperative delirium: a pilot study in older adults undergoing open colon surgery].

Background: Post-operative delirium is a serious complication in patients undergoing major abdominal surgery. It remains unclear whether peri-operative hemodynamic and perfusion variables affect the risk for postoperative delirium. The objective of this pilot study was to evaluate the association between perfusion and hemodynamics peri-operative with the appearance of post-operative delirium.

[Early enteral nutrition in cancer patients subjected to a total gastrectomy].

Background: Total parenteral nutrition has a high cost and frequency of complications. Enteral feeding is a feasible alternative that can be started early in the postoperative period.

Aim: To assess digestive tolerance to early enteral feeding in cancer patients undergoing total gastrectomy and to compare early enteral feeding (EEF) with total parenteral nutrition plus enteral feeding (TPN + EF), initiated after overcoming postoperative ileus.
