Abstract: Background and Aims: Hypotension is one of the most frequent side effects of spinal anesthesia. Crystalloid preloading prior to administration of spinal anesthesia to prevent hypotension is common. The aim is to study the effectiveness of preloading for the prevention of spinal anesthesia induced hypotension in lower limb surgery. Methods: 30 patients aged 18 to 65 years of either sex, scheduled for below umbilical surgery under spinal anesthesia were preloaded with 20ml/kg ringer lactate 20mins before spinal anesthesia. All patients were given subarachnoid block with 3ml of bupivacaine heavy with a 25gauge spinal needle at the L3-L4 intervertebral space. Mephentermine 6 mg was administered when the mean blood pressure fall less than 64 mmhg and atropine 0.6mg given to those patients whose heart rate decreased below 55 beats/min. Patients were observed for HR, SBP, DBP, MAP and SPO2 every 5 minutes until the end of the surgery. Result: Mean baseline value and trends at various time intervals of heart rate, systolic blood pressure, diastolic blood pressure, mean blood pressure were recorded. Total incidence of hypotension was 13.33% (4 out of 30 patients) and total incidence of bradycardia was 6.67% (2 out of 30 patients). Conclusion: Preloading with 20ml/kg ringer lactate 20 mins prior to induction of spinal anesthesia is effective in prevention of hypotension.
