Although spinal anaesthesia is a popular medical practice worldwide for surgical procedures, it can be associated with numerous adverse events. They may be due to anaesthetic agents, procedures, techniques and coincidental events as well. Descriptive cross sectional study design was conducted among patients admitted to Base Hospital Thambuththegama to undergo surgery under spinal anaesthesia. Patients who were treated with immunosuppressive medicines as a prophylactic measure to prevent drug allergies were excluded from the study. Systematic random sampling technique was applied to recruit 397 patients. Interviewer administered structured questionnaire was used as the study instrument in all three languages. Data was analyzed by using standard statistical software. No conflicts of interests to be declared. Age of the participant were ranged from 18 years to 86 years (Mean=39.8 yrs:SD=16.6 yrs). Majority of the participants were below 45 yrs (n=287:72.3%). Female predominance were observed in the study sample. Prevalence of the detection of adverse events following spinal anesthesia was 60%(n=238:95%CI=55.1-64.3). Highest number of participants were experienced Hypotension during surgery. Bradycardia and shivering were the other prominent presentations. Majority of adverse events were observed during surgery and occurrence of adverse events in post operative period was relatively less. Female gender, Lower Segment Cesarean Sections were significantly associated with the occurrence of adverse events following spinal anaesthesia. The findings in present study align with much of the published research on spinal anesthesia, especially regarding the high rate of hypotension, bradycardia, and shivering during surgery, particularly in female patients undergoing LSCS. However, the reported overall prevalence of adverse events (60%) seems slightly elevated compared to some other studies, likely due to the inclusion of obstetric surgeries where complications are more frequent. It would be valuable to compare results with other populations, including non-obstetric patients, to further understand the nuances of adverse events following spinal anesthesia..
