Fig. 2 — The change of sonographic ONSD at four specific time-points. ONSD decreased significantly between time-points 2 and 3 (P < 0.001). ONSD values at time-point 3 and 4 were significantly decreased compared with values at time-point 1 and 2. ONSD did not show differences between two time-points in the same ETCO₂ level (time-point 1 vs. 2, and 3 vs. 4). ONSD: optic nerve sheath diameter, ETCO₂: end-tidal carbon dioxide concentration. ^*P < 0.001 (compared with time-point 1 and 2).
