Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of the effects of colloid and crystalloid solution for volume preloading on maternal hemodynamics and neonatal outcome in spinal anesthesia for cesarean section].
The role of crystalloid or colloid preloading to prevent hypotension associated with spinal anesthesia in parturients during cesarean section has recently been questioned. The aim of the current study was to investigate the effects of volume preload with either crystalloid or colloid, or with no preload on changes of maternal hemodynamics and neonatal outcomes. ⋯ In healthy patients with full-term pregnancy, volume preloading has little effect on maternal hemodynamics and neonatal outcomes, suggesting that stable perioperative management is possible with or without volume preload before spinal anesthesia. However, preloading may be needed for prevention of hypotension in emergency cases.
