Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate the accuracy and correlation of estimating arterial CO2 pressure（PaCO2） using a transcutaneous CO2 pressure（PTCCO2） monitor in patients undergoing retroperitoneoscopic renal or adrenal surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

30 patients undergoing retroperitoneoscopic renal or adrenal surgery were included in this study.Their PaCO2, PetCO2, and PTCCO2values were measured at 3 time points before and 30min, 60min after pneumoperitoneum and calculated the different between each measure(PetCO2 and PTCCO2) and PaCO2. Agreement among measures was assessed by the Bland-Altman method.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

retroperitoneoscopic urologic surgery

All included patients will undergo retroperitoneoscopic renal or adrenal surgery with the transcutaneous carbon dioxide monitor.

Group Type EXPERIMENTAL

transcutaneous monitor (TCM-4 monitor)

Intervention Type DEVICE

TCM-4 monitor, which had changed new electrode membrane and was calibrated by the same person(who had been trained systematically) before each placement. The electrode should be heated to 44℃, then fixed it to the anterior part of chest in the location of lateral position after remove grease by alcohol. The positon of electrode must be changed every 2 hours in order to avoid thermal injury, and should be calibrated again.
