ADVERSE EFFECTS, SECONDARY
The primary outcome was the incidence of post-spinal anesthetic hypotension. According to previous studies, the incidence of post-spinal anesthetic hypotension may be as high as 70% [Total fluid volume, vasopressor dosage, changes in hemodynamic parameters, maternal adverse effects, and neonatal status were the secondary outcome measures.SPSS version 22 (IBM Corp., Armonk, NY, USA) was used to perform statistical analyses. To examine the normality of the distribution of univariate inter-group data, Q-Q plots and the Shapiro–Wilk test were utilized. Normally distributed outcome data are reported as mean (standard deviation [SD]) and Student’s t-test was used to compare groups. The Mann–Whitney U-test was used to examine non-normally distributed data that are summarized as median [interquartile range]. The chi-squared test was used to assess categorical variables. Statistical significance was set at p < 0.05.
