EFFICACY OF CRYSTALLOIDS AND COLLOIDS AS PRELOADING FLUIDS TO PREVENT HYPOTENSION IN SPINAL ANESTHESIA IN ELECTIVE C-SECTIONS

Abstract

Background: Different crystalloids commonly used in preloading are Ringer lactate, normal saline and colloids that are used in preloading are gelatin, dextran, hetastarch, pentastarch, tetrastarch. This study was aimed to compare the efficacy of both as preloading infusion to prevent hypotension, requirement of vasopressors and requirement of total fluid given during surgery to maintain stable hemodynamics

Methods: This randomized control trials was conducted in the Department of Anaesthesia , R.V.R.S. Medical College, Bhilwara.  60 patients between 18- 40 years of age, belonging to American society of anaesthesia grade I or II going for elective caesarian section under spinal anesthesia were screened for the study eligibility criteria

Results: In group (I), in 20 females, efficacy was achieved while in 10 females efficacy could not be achieved because of drop in BP. In group (II), in 22 females, efficacy was achieved while in 8 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=>0.05)

Conclusion: According to this randomized trial we did not find any significant difference between both groups for prevention of hypotension.
