[Retracted] Effect of Dexmedetomidine Combined with Ropivacaine on Cognitive Dysfunction and Inflammatory Response in Patients Undergoing Craniocerebral Surgery

Figure 5

Comparison of oxygen saturation between the two groups at different times. Note: the abscissa from left to right represents T0, T1, T2, T3, and T4, and the ordinate represents oxygen saturation. There was no statistically significant difference in the comparison of the oxygen saturation at T0 between the experimental group () and the control group (; , ). There was no statistically significant difference in the comparison of the oxygen saturation at T1 between the experimental group () and the control group (; , ). There was no statistically significant difference in the comparison of the oxygen saturation at T2 between the experimental group () and the control group (; , ). There was no statistically significant difference in the comparison of the oxygen saturation at T3 between the experimental group () and the control group (; , ). There was no statistically significant difference in the comparison of the oxygen saturation at T4 between the experimental group () and the control group (; , ).
