All of the following are the complications of laparoscopy, except:
|A||Increased systemic vascular resistance|
|B||Decreased cardiac output|
|D||Decreased renal artery pressure|
Decreased renal artery pressure
Increased intra-abdominal pressure by CO2 insufflation compresses the vena cava which can significantly (up to 30-35%) decrease the cardiac output. Brady. arrhythmias may occur due to sudden peritoneal stretching by CO2 insufflation. Systemic vascular resistance is increased by hypercapnia and increased levels of vasopressin and catecholamines. Vascular resistance: of all abdominal organs (except adrenals) is significantly increased leading to decreased blood flow (and this, increase in vascular resistance is because of increased intra-abdominal pressure).
