title: [Hemodynamic and respiratory changes caused by CO2 laparoscopy in an experimental model of diaphragmatic injury].
abstract: OBJECTIVE
  The objective of this study was to analyze the hemodynamic and respiratory changes caused by CO2 laparoscopy in an experimental model of diaphragmatic injury.
  
  
  METHODS
  Fifteen animals chosen at random were submitted to diaphragmatic injury by means of CO2 laparoscopy. Evaluation consisted of drawing blood samples to analyze blood gases, as well as the hemodynamic and respiratory variables.
  
  
  RESULTS
  Alterations occurred in APA, CPP, PAO2, ASO2, VSO2.
  
  
  CONCLUSIONS
  We concluded that videolaparoscopy with pneumoperitoneum pressure under 15 mmHg is a safe procedure in patients with diaphragmatic injuries because this pressure level does not cause hemodynamic changes, such as decrease of the cardiac output.
