A total of 1403 cases were reviewed. After exclusions for insufficient IV fluids documentation, 1023 cases were included in the analysis (Figure 1). The volume of IV fluids administered ranged from 0 mL to 5751 mL. Two types of crystalloid IV fluids were used: 0.9% Normal Saline and Hartmann’s solution (Compound Sodium Lactate). These were administered at variable rates. The low-volume IV fluids group (<2500 mL) included 810 cases, and the high-volume IV fluids group (≥2500 mL) included 213 cases. Maternal demographics and clinical characteristics for the two groups are summarised in Table 1 and Table 2.
