Data were shown as mean ± SD. The comparisons between pre- and post-op measurements within each group, Paired t-test, according to the Bonferroni Correction P < 0.025 was considered as statistically significant. The comparisons between control and study groups, Student’s t test, according to the Bonferroni Correction P < 0.025 was considered as statistically significant except for the comparisons at the last column. SBP: Systolic blood pressure; DBP: Diastolic blood pressure; HR: Heart rate; SAT: Peripheral oxygen saturation; RR: Respiratory rate.
