Key result
Cardiac output measured by the carbon dioxide rebreathing technique strongly correlated with the thermodilution method during laparoscopic surgery in a single patient.
Why the study?
Does the carbon dioxide rebreathing technique accurately measure cardiac output compared to the thermodilution method in a patient undergoing laparoscopic surgery?

Does the carbon dioxide rebreathing technique accurately measure cardiac output compared to the thermodilution method in a patient undergoing laparoscopic surgery?
The carbon dioxide rebreathing technique can be used to monitor cardiac output during laparoscopic surgery, showing strong correlation with the thermodilution method.
May support CO2 rebreathing for intraoperative cardiac output monitoring; hypothesis-generating and requires prospective validation.
In Brief Carbon dioxide insufflation during laparoscopic surgery may interfere with the accuracy of the cardiac output value measured by the NICO2™ system. The authors simultaneously measured cardiac output by the thermodilution method and by the carbon dioxide rebreathing technique during laparoscopic adrenalectomy in a patient with a nonfunctional adrenal tumor. There was a strong correlation between the cardiac output values measured by the two methods. This case report suggests that the carbon dioxide rebreathing technique can be used to monitor cardiac output during laparoscopic surgery. IMPLICATIONS: Cardiac output can be monitored by the carbon dioxide rebreathing technique during laparoscopic surgery.

Suzuki et al. (2005) conducted a case report in Nonfunctional adrenal tumor undergoing laparoscopic adrenalectomy (n=1). Carbon dioxide rebreathing technique vs. Thermodilution method was evaluated on Correlation of cardiac output measurements. Cardiac output measured by the carbon dioxide rebreathing technique strongly correlated with the thermodilution method during laparoscopic surgery in a single patient.
