Clinical Trial Summary

The measurement of VO2 and VCO2 makes it possible to calculate the respiratory quotient (RQ) (VCO2 / VO2) which is a reflection of human energy metabolism and therefore of anaerobiosis. A study has been conducted in our department to demonstrate the ability of the indirectly measured RQ from the inspired and exhaled breath analysis of the anesthetic respirator to predict the onset of anaerobic metabolism and postoperative complications in the operating room.

But, because of artificially increase of carbon dioxide due to insufflation, coelioscopic surgery was an exclusion criteria of our pilot study.

However, no study has examined the impact of coelioscopy on the indirect measurement of RQ

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Indirect respiratory quotient by measurement of VO2 and VCO2	The measurement of VO2 and VCO2 makes it possible to calculate the respiratory quotient (RQ) (VCO2 / VO2)	during coelioscopic surgery
Secondary	occurence of at least one post-operative complication	the aim is to predict the occurence of at least one complication with the use of indirect respiratory quotient	through study completion, an average of 6 months
