[New device and technique to measure intra-abdominal pressure].

Introduction: sequential measurement of intra-abdominal pressure is of paramount importance for an early detection and appropriate therapeutic management of intra-abdominal hypertension and abdominal compartment syndrome.

Objective: to validate a device and technique developed to measure intra-abdominal pressure (an innovation of the Foley urinary catheter named intra-abdominal pressure catheter).

Methods: three different sets of measurements where done to test the intra-abdominal pressure catheter device: I.

[Effects of different positive end expiratory pressure levels on resting energy expenditure measured by indirect calorimeter in patients with pressure-controlled ventilation].

Objective: To identify variations during measurements of resting energy expenditure (REE), oxygen consumption (VO2) and CO2 production (VCO2) by indirect calorimetry (IC) in patients with pressure-controlled ventilation and different levels of positive end expiratory pressure (PEEP).

Design: Prospective and comparative study.

Setting: Intensive care unit (ICU) of a university-affiliated hospital.
