Data are presented as p-value. ANOVA with repeated measures was used to compare the changes in SpO2 and p-value calculated. Bonferroni’s multiple comparison tests were used to make intergroup comparisons.
• There was no statistically significant difference in Intra-operative SpO2 in three groups (p>0.05).
