Background: Spinal anesthesia is preferred by both mothers and surgeons due to its multiple advantages. The present study determined maternal and anaesthesia-related risk factors and incidence of spinal anaesthesia-induced hypotension in elective caesarean section. Materials & Methods: 100 full-term pregnant females scheduled to undergo elective CS under SA were assessed for systolic blood pressure (SBP), diastolic blood pressure (DBP), BMI (kg/m2), gravidity, height, weight, previous abortions and previous abortions etc. Results: Hypotension was not present in 35, mild in 40, moderate in 20 and severe in 5. The mean weight was 74.2 Kgs, 79.4 Kgs, 79.8 kgs and 79.0 Kgs, mean height was 160.2cms, 163.4cms, 162.1cms and 162.0cms in patients with mild, moderate and severe hypotension respectively. BMI was 18.5- 20 Kgs/m2 seen in 18, 20, 3 and 1, 25-30 Kgs/m2 in 10, 8 and 4 and 2 and >30 Kgs/m2 in 7, 12, 3 and 2 patients without, mild, moderate and severe hypotension respectively. Gravidity was 1 seen in 20, 4 and 3, 2 seen in 12, 4 and 1 and >2 in 8, 2 and 1 in patients with mild, moderate and severe hypotension respectively. The difference was significant (P< 0.05).History of stillbirth was seen among 10, 4 and 5, history of previous abortion in 12, 7 and 7, previous CS was seen in 15, 8 and 9, history of hypotension in 16, 12 and 11 in mild, moderate and severe hypotension patients respectively. The difference was significant (P< 0.05).Conclusion: Authors found that main risk factors forSA-induced hypotensionwas height, weight, BMI, gravidity, previous abortions and previous abortions.
