Changes in heart rate (HR). Although a slight increasing trend was observed in HR over time, this change was tolerable. A slight increase in HR at insufflation and 30 min after insufflation compared to the baseline (P <0.05) was observed in the 9-mmHg group. Significant differences were not observed between the groups. Data are expressed as the mean ± SD. * P < 0.05 versus baseline value.
