ADVERSE EFFECTS
The total fluid volume was significantly higher in the control group than in the SCVUS group (690 [650–757.5] vs. 160 [80–360] mL, p < 0.001), while the phenylephrine dose (0 [0–40] vs. 0 [0–30] µg, p = 0.276) and incidence of post-spinal anesthetic hypotension (65% vs. 60%, p = 0.950) were comparable between both the groups. The incidence of maternal adverse effects, including nausea/vomiting and bradycardia (12.5% vs. 17.5%, p = 0.531 and 7.5% vs. 5%, p = 1.00, respectively), and neonatal outcomes (Apgar scores) were comparable between the groups. SCVCI correlated with the amount of fluid administered (R = 0.885, p < 0.001).
