  1. 1, One min after insertion of the gastric tube; 2, Two min after intravenous administration of neuromuscular blocking drug; 3, One min after initiation of pneumoperitoneum; 4, One min after change to the Trendelenburg position. Data are shown as number (proportion), median [interquartile range].
