Haemodynamic changes and vasopressin release are not consistently associated with carbon dioxide pneumoperitoneum in humans.


BACKGROUND Conflicting haemodynamic changes, suggested to be caused by vasopressin release, have been reported during carbon dioxide (CO2) pneumoperitoneum. However, peritoneal stimulations including open surgery cause both a systemic vasopressor response and a vasopressin release, which are suppressed by opiate administration. Also, a decreased venous… (More)
