Effects of intra‐abdominal CO₂‐insufflation on normal and impaired myocardial function: an experimental study

Abstract

Following the acute elevation of IAP, the right ventricular volume load shifted more extensively in the IMF groups than in the animals with normal myocardial function. Myocardial function in the impaired heart may worsen during IAP elevation due to right ventricular load alterations rather than a LV afterload increase.

A novel balloon technique to induce intra‐abdominal hypertension and its effects on cardiovascular parameters in a conscious dog model

“…Some studies have shown that sustained IAH has a profound effect on the cardiovascular system . A decrease in cardiac output and compensatory tachycardia was observed in response to an increase in intrathoracic pressure and a decrease in stroke volume, whereas other studies showed IAH to have a minimal effect on cardiac output . In the current study, an increase in IAP to 10, 15, 20, or 25 mmHg caused a slight but statistically insignificant increase in HR and SAP in conscious dogs.…”
