Table 43-4

  • Increased cerebral perfusion and intracranial pressure
    • Caution in patient with brain tumor or ventriculoperitoneal shunt
  • Decreased splanchnic blood flow
    • Decreased or no change in bowel perfusion (mechanical pneumoperitoneum compression balanced by hypercarbic vasodilation)
    • Decreased hepatic blood flow (beneficial during cryoablation of liver metastasis)
    • Reduced renal perfusion and urine output (reduced during pneumoperitoneum with recovery after deflation)
  • Decreased femoral vein flow
    • Increased potential for deep vein thrombosis and pulmonary embolism
