Efficacy of crystalloids and colloids as preloading fluids to prevent hypotension in spinal anesthesia in elective c-sections at m.g.hospital bhilwara, rajasthan

Background- Spinal anaesthesia is commonly used for C-section. Hypotension from spinal anaesthesia results from sympathetic blockade which causes vasodilatation and increase in capacitance vessels.
Methods- This randomized control trials was conducted in the Department of Gynae & Obs, M.G. Hospital Bhilwara. A sample size of 100 cases;50 cases in each group.
Results- In group (I), in 35 females, efficacy was achieved while in 15 females efficacy could not be achieved because of drop in BP. In group (II), in 36 females, efficacy was achieved while in 14 females, efficacy could not be achieved. The difference between both groups was statistically insignificant but there were more females in group II in which efficacy was achieved. (p-value=0.784)
Conclusion- According to this randomized trial we did not find any significant difference between both groups for prevention of hypotension.
