Not many studies have explored the correlation between arterial carbon dioxide tension (PaCO2) and end-tidal carbon dioxide tension (ETCO2) in surgeries requiring pneumoperitoneum of more than 1 hour duration with the patient in non-supine position. The aim of our study was to evaluate the correlation of ETCO2 with PaCO2 in patients undergoing laparoscopic nephrectomy under general anaesthesia. ⋯ Continuous ETCO2 monitoring is a reliable indicator of the trend in arterial CO2 fluctuations in the American Society of Anesthesiologists Grades 1 and 2 patients undergoing laparoscopic nephrectomy under general anaesthesia.
