Data are presented as mean and standard deviation
Post-operative vital data events were compared between the three groups, mean blood pressure was lower in the epidural group (group A) compared to the femoral and adductor groups (group B and C). Although, there was no significant difference between the femoral & adductor groups
BP Blood pressure
P value less than 0.05 was considered statistically significant. pairwise comparison within the ANOVA data was done using post hoc Tukey’s test
