Have there been changes in the application of mechanical ventilation in relation to scientific evidence? A multicenter observational study in Mexico.

Objective: The main study objectives were to describe the practice of mechanical ventilation over an 18-year period in Mexico, and estimate changes in mortality among critical patients subjected to invasive mechanical ventilation (IMV).

Design: A retrospective subanalysis of a prospective observational study conducted in 1998, 2004, 2010 and 2016 was carried out.

Setting: Intensive Care Units (ICUs) in Mexico.

Incidence of gastric mucosal injury as measured by reactance in critically ill patients.

Gastric reactance has been proposed as a measure of mucosal ischemic injury in the critically ill. The purpose of this study was to evaluate the incidence of gastric mucosal injury as measured by gastric reactance in different subgroups of critical patients. We studied 100 adult patients admitted to 7 different hospital intensive care units, requiring a nasogastric tube.
