title: [Monitoring of intra-abdominal pressure and abdominal perfusion pressure in urgent abdominal surgery].
abstract: OBJECTIVE
  To evaluate the changes in intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) during perioperative period in urgent abdominal surgery and to assess the relationship of these parameters with gas exchange and tissue perfusion.
  
  
  METHODS
  Twenty-four patients undergoing emergency abdominal surgery were enrolled into a prospective observational study. We recorded IAP APP, mean arterial pressure, arterial and venous blood gases after induction of anesthesia, at the end of surgery, and 6, 12, 48 and 72 h postoperatively. LAP was measured by nasogastric tube using CiMON monitor (Pulsion Medical Systems, Germany). In addition, we studied the relationship of IAP and APP with blood gases parameters.
  
  
  RESULTS
  We observed perioperative increase of IAP (> 12 mm Hg) in 75% of enrolled patients, tendency to postoperative rise of IAP and transient increase of arterial lactate at 6 h after surgery. APP remained within normal values. We found positive correlation of APP with PaO2/FiO2 and ScvO2 at 72 hours after surgery.
  
  
  CONCLUSIONS
  Transient perioperative increase of IAP was observed in 75% patients undergoing urgent abdominal surgery; however in parallel with intensive care the abdominal perfusion pressure remained within normal values. Abdominal perfusion is related with arterial oxygenation and central venous saturation.
