Effect of Crystalloid or Colloid Fluid Loading and Vasopressor Pre-Treatment on the Timing of Hypotension in Cesarean Section with Subarachnoid Block

BACKGROUND: Cesarean section (C-section) is the most frequently performed surgery in obstetrics, generally using subarachnoid block (SAB) or epidural for anesthesia. The previous studies have shown effectiveness of fluid loading and vasopressor pretreatment preventing maternal hypotension (decreased blood pressure), common side effect SAB. However, timing response to these treatments has not been analyzed. AIM: This study therefore aimed compare effects crystalloid colloid pre-treatment on cases C-section under SAB METHODS: was a single-blind randomized controlled clinical trial with three treatment groups: Group I, 10 mL/kgBW solution (Ringer’s lactate) min before SAB; II, 5 (gelatin) III, 0.1 mg/kgBW (ephedrine) intravenous bolus just RESULTS: Significant differences mean pressure between groups were observed second 8th (p < 0.05). Hypotension group within first min, while average relatively stable all after min. In addition, occurred more (nine subjects, 45%), compared (two subjects per group, 10%; p CONCLUSION: rapidly when utilized, pretreatment. Administration prevent
