Abstract: Background: Spinal anesthesia is the most common regional anesthesia widely used for many surgical abdominal, lower limb surgeries. Multiple spinal needle placement attempts may be hazardous. Appropriate preoperative prediction of difficulty helps to the delivery of high quality care. Aims and Objectives: The aim of the study is to predict the difficulty score of spinal anesthesia, by which to reduce the complications and improve the anesthesia quality. Materials and Methods: An observational study was done in the department of Anesthesiology of a rural tertiary care hospital between February 2021 and June 2022. A total of 122 patients scheduled for elective lower limb surgeries were considered and relevant data was taken from it. Results: As the age and Body mass index increases the difficulty score, number of attempts, number of new skin pricks increases. As the Body mass index increases, difficult to palpate spinous process. Conclusion: The proper clinical examination of patients before spinal anesthesia focusing on Lumbar spinous process, presence of lumbar deformity, calculation of BMI and radiological signs of lumbar vertebrae can be helpful in predicting spinal anesthesia difficulty.
