Introduction: Spinal anaesthesia complicates maternal hemodynamic and may expose the parturient to dangerous cardiovascular problems. Aims: To compare the hemodynamic in normotensive and preeclampsia pregnant women posted for caesarean section under spinal anaesthesia. Materials and methods: A prospective and comparative study carried out in Pregnant women of ASA physical status I and II or III, between 20 to 30 years of age, carrying single live, healthy fetus posted for elective caesarean section who satisfy the following inclusion and exclusion criteria. A total of 100 (Minimum of 50 in each group) pregnant women who scheduled to undergo elective caesarean section. Results: Multigravida was observed in normotensive group subjects and primagravida was observed more in preeclampsia group subjects. The women in normotensive group had higher gestational ages, was statistically extremely significant. Mean height and weight in normotensive group and preeclampsia group had no statistical significance. The baseline heart rate, blood pressure were significantly higher in severe preeclamptic women and percentage decrease was statistically not significant. For the hypotension episodes, requirements of vasopressors, dose of vasopressor and IV fluids the difference between the groups was statistically significant. Conclusion: Our findings have led us to conclude that spinal anesthesia does not cause precipitous drop in blood pressures in severe preeclamptic women as was once thought. Further studies are required to prove the same.
