Insufflation of CO2

CO2 is introduced into the abdomen via a needle or port, with continuous monitoring of intraabdominal pressure.

Peritoneal stretch receptors sense the increase in intraabdominal pressure and respond by triggering increased vagal tone.
Close monitoring is required as patients may develop severe bradycardia, AV block, and sometimes asystole.
The increased intraabdominal pressure can also cause a mechanical increase in systemic vascular resistance leading to elevations in BP.
