Abstract：Objective:To observe the influence of CO 2 insufflation on arterial blood gas in patients in moderate altitude region,undergoing urological retroperitoneal laparoscopic operations.Methods:A total of 35 patients under-went urological retroperitoneal laparoscopic surgeries from January 2012 to October 2014.The mean age of these pa-tients was 48 years-old,including 22 males and 18 females.Pneumoretroperitoneum (12 to 14 mm Hg,CO 2 )was established after general anesthesia.Arterial blood samples were collected for arterial blood gas analysis at three time points:0 min,30 min and 60 min after insufflation.Parameters including pH,PaCO 2 and PaO 2 were tested.Re-sults:Compared with 0 min,pH values at 30 min and 60 min were significantly decreased (P < 0.01 ),and the PaCO 2 values at 30 min and 60 min were greatly increased (P <0.01).There were no significant differences in both pH and PaCO between 30 min and 60 min (P >0.05).During the operation,PaO 2 was maintained at a high level, and no significant differences were found among three time points (P >0.05 ).Conclusions:Retroperitoneal carbon dioxide insufflation has a risk of hypercapnia which should be carefully detected during the surgery.
