Intrathoracic and pulmonary blood volume during CO2-pneumoperitoneum in humans.

BACKGROUND Induction of CO2-pneumoperitoneum may have significant effects on systemic and pulmonary haemodynamics. We hypothesized that intrathoracic (ITBV) and pulmonary blood volume (PBV) are affected during intra-abdominal CO2-insufflation, which may be pronounced by positional changes of the patient. METHODS Sixteen anaesthetized patients were studied… CONTINUE READING
