Perioperative goal directed fluid therapy may reduce complication rate after surgery. Minimal invasive cardiac output monitoring is a key method to guide fluid therapy. More operations are being performed by keyhole surgery (laparoscopy). For laparoscopy, the abdomen is filled with carbon dioxide. Increased pressure in the abdomen may influence minimal cardiac output monitoring, therefore minimal cardiac output monitoring is not recommended during laparoscopy. This study aims to validate minimal cardiac output monitoring during laparoscopy and therefore facilitate for goal directed fluid therapy.

Condition Intervention
Procedure: Pneumoperitoneum and SVV/PPV

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Health Services Research
Official Title: The Influence of Pneumoperitoneum on Minimal Invasive Cardiac Output Measurements

Further study details as provided by Haukeland University Hospital:

Primary Outcome Measures:
  • Change of stroke volume variation and pulse pressure variation during pneumoperitoneum [ Time Frame: peroperative ]
    Change in PPV/SVV(LiDCO), PPV(Philips) and SVV/CO(TEE) in percent before and after pneumoperitoneum.

Secondary Outcome Measures:
  • Difference in measurements from different methods of minimal cardiac output monitoring. [ Time Frame: peroperative ]
  • Effect of fluid bolus under pneumoperitoneum (responder vs. non-responder) [ Time Frame: peroperative ]
