Comparison of preload versus coload by crystalloid in parturients undergoing caesarean section under spinal anaesthesia: an analytical study

Background: Spinal anesthesia is popular, simple and well accepted reliable technique for below umbilicus surgery. It frequently used lower segment section because of its rapid onset, a dense neural block, avoidance risk airway, little local anesthetic toxicity minimal transfer drug to the fetus, as failure block. Objectives this study was compare incidence severity hypotension, dose requirement mephentermine maternal bradycardia, shivering, nausea, vomiting. Methods: ASA grade I, II parturients posted elective cesarean were randomly allocated in two groups 55 each receive either preload or co-load with Ringers lactate solution, blood pressure, heart rate, other outcomes recorded at regular interval. Results: Hypotension observed significantly less co-loading group (37.18%) than preloading (61.81%). Mean vasopressor also more group. Heart rate change, vomiting fetal outcome remained same across both groups. Conclusions: Co-loading crystalloids effective strategy prevention spinal induced hypotension. We can save valuable time given case emergency caesarean sections.
