The Effect of Intra-abdominal Pressure on Peritoneal Perfusion During Laparoscopic Colorectal Surgery (PERFUSION)
May 7, 2020 updated by: Radboud University Medical Center
The Effect of Intra-abdominal Pressure on Peritoneal Perfusion During Laparoscopic Colorectal Surgery: a Pilot Study
Peritoneal perfusion during laparoscopic surgery is quantified by video recording after intravenous injection of indocyanine green at a pneumoperitoneum pressure of 8, 12 and 16 mmHg.

Peritoneal perfusion
Time Frame: 3 minutes after intravenous injection of indocyanine green
|
Perfusion is quantified by video recording of the parietal peritoneum using the Firefly fluorescence module of the DaVinci surgical robot after intravenous injection of 0.2mg/kg indocyanine green.
Fluorescent intensity in [-] over time is plotted in MATLAB, maximum fluorescent intensity and time to reach maximum fluorescent intensity are extracted.
