Abstract

Comparative study of preloading colloid fluids with not preloading colloid fluids for prevention of hypotension in patients undergoing elective cesarean section delivery after subarachnoid block. Material and methods: 120 patients were divided in to two groups. 60 in each group. Group A - preloaded with colloid fluids: Preloading was done with 10-20 ml/kg of colloid, 20-30min prior moving patient to OT. Subarachnoid block was given with anaesthetic drug, then patient was placed in supine position. After the achievement of adequate level of block, systolic blood pressure , diastolic blood pressure and mean arterial blood pressure were recorded .Group B - not preloaded colloid solution : Subarachnoid block was given with anaesthetic drug, then patient was placed in supine position. After the achievement of adequate level of block, systolic blood pressure , diastolic blood pressure and mean arterial blood pressure were recorded. Results: Most common diagnosis in Group A was POG with Previous LSCS (45%) whereas most common diagnosis in Group B was POG with PROM (33.3%). The post subarachnoid block lower SBP was more common in Group B patients as compared to group A patients (p<0.001). The post subarachnoid block lower DBP (hypotension) was more common in Group B patients as compared to group A patients (p<0.001). The post subarachnoid block lower MAP (hypotension) was more common in Group B patients as compared to Group A patients (p<0.001). Patients receiving preloading colloid fluids had lower incidence of hypotension compared to those not receiving preloading colloid fluids. Time interval when hypotension occurs after subarachnoid block was significantly longer in patients of Group A (9.30±1.951) who received preloading colloid fluids as compared to Group B (6.00±1.747) patients who did not received preloading colloid fluids. Conclusion: We concluded that the parturient undergoing elective cesarean section when preloaded with colloid fluids, revealed less hemodynamic changes in terms of SBP, DBP and MAP as compared to those who were not preloaded with colloid.
