Background: Therefore the present study was undertaken to study on comparison of 6% hydroxyl ethyl starch with Ringer’s Lactate for preloading in caesarean section under spinal anaesthesia. Objectives: To study the effects on heart rate and blood pressure after pre-load with 6% hydroxy ethyl starch and ringer’s lactate in elective caesarean section after spinal anaesthesia. Methods: Total of one hundred patients belonging to ASA Grade I and II were included in the study during study duration. Patients in the age group of 18-35 years were selected. Through pre-operative examination was done one day prior to access the fitness for anaesthesia. Routine investigation like Haemoglobin, urine for sugar and albumin were done. Other investigations were carried out whenever necessary. The patients were randomly divided into two groups comprising of 50 patients in each group. Group A: received Lactated Ringer’s solution 1000ml. Group B: received 500ml. of 6% Hydroxy Ethyl Starch. Results: There was no statistically significant difference found in pulse rate and blood pressure parameters at baseline between two groups (p>0.05). It was found that there is no statistically significant difference of pulse rate during first hour after the Subarachnoid injection between the two groups (p>0.05). It was found that, there is no statistically significant difference of changes in respiratory rate and SpO2 between the two groups (P>0.05). Conclusion: From the present study, it was conclude that, preloading subjects with 6% hydroxyl ethyl starch is useful than preloading with ringer lactate solution as it produces better hemodynamic stability to subjects.
