Abstract

To examine the adverse effects of peritoneal carbon dioxide (CO2) insufflation during laparoscopic cholecystectomy, both hemodynamic and respiratory alterations were continously monitored in 17 adult patients using noninvasive Doppler ultrasonography and a continuous spirometric monitoring device. During the surgery, which was performed under inhalational general anesthesia, intraabdominal pressure was maintained automatically at 10mmHg by a CO2 insufflator, and a constant minute ventilation, initially set to 30-33 mmHg of end-tidal CO2 (ETCO2), was maintained. Despite considerable depth of anesthesia, peritoneal CO2 insufflation induced a significant and immediate increase of mean blood pressure (+42%) and systemic vascular resistance (+62%), accompanied by a slight depression of cardiac index (-12%, nonsignificant), while the ETCO2 gradually increased and maximized around 30min following the initial CO2 insufflation. The stress of 10mmHg pneumoperitoneum was a major cause of hemodynamic changes during laparoscopic cholecystectomy. Some clinical strategies such as deliberate intraabdominal insufflation at the initial phase might be required to minimize these hemodynamic changes.
