Brief Summary:
This will be a randomized study aiming at investigating the combination of a norepinephrine infusion and colloid preloading versus the combination of a norepinephrine infusion and crystalloid co-loading for the prevention of maternal hypotension during elective cesarean section
Detailed Description:
Neuraxial techniques are the anesthetic techniques of choice in contemporary obstetric anesthesia practice, with a definitive superiority as compared to general anesthesia, since, by their use, serious complications involving the airway can be avoided.Spinal anesthesia has become the favorable technique for both elective and emergency cesarean section due to a quick and predictable onset of action, however, it can be frequently complicated by hypotension, with incidence exceeding 80% occasionally. Recently, noradrenaline has been shown to be effective in maintaining blood pressure in obstetric patients. Another technique widely used to prevent hypotension is fluid administration. Current evidence suggests that the combination of fluid administration and vasoconstrictive medications should be the main strategy for prevention and management of hypotension accompanying neuraxial anesthesia procedures during cesarean section. Research is still underway in relation to the most appropriate timing for fluid administration, the most appropriate fluid volume as well as the type of fluid that should be administered. However, preloading of crystalloids seems to be inefficient as a sole strategy, while co-loading of colloids is more effective than co-loading of crystalloids for prevention of hypotension in the parturient. On the other hand, preloading and co-loading of colloids seem to be of equal effectiveness. Literature is rather scarce regarding the comparison of colloid preloading and crystalloid co-loading.
The aim of this randomized study will be to investigate the combination of a norepinephrine infusion and colloid preloading versus the combination of a norepinephrine infusion and crystalloid co-loading for the prevention of maternal hypotension during elective cesarean section.
