Figure 1: Changes of MAP and HR (a); RR (times/min), EtCO2(mmHg), and SpO2(%) (b) During every step of colonoscopy. Time point: (1) in the initial setting (n = 120 in Group 1, n = 116 in Group 2), (2) 5 min after RP infusion (n = 120 in Group 1, n = 116 in Group 2), (3) 10 min after RP infusion (n = 120 in Group 1, n = 116 in Group 2), (4) 15 min after RP infusion (both n = 89), (5) 20 min after RP infusion (n = 47 in Group 1, n = 41 in Group 2), and (6) 25 min after RP infusion (n = 18 in Group 1, n = 22 in Group 2). Data were presented as mean ± SD *P < 0.05 compared with Group 1 at each time point measurement; P < 0.001 compared with Group 1 at each time point measurement. Ce = Effect-site concentration; RP = Remifentanil–propofol; bpm: Beats per minute; EtCO2= End-tidal carbon dioxide pressure; HR: Heart rate; MAP: Mean arterial pressure; OAA/S scale = Observer's Assessment of Alertness/Sedation Scale; RR = Spontaneous respiratory rate; SpO2= Peripheral oxygen saturation; SD = Standard deviation
