The level and time block in patients undergoing spinal anesthesia are affected by body mass index [BMI] and the amount of cerebrospinal fluid.So the purposes this review were to evaluate the relationship between BMI and time of spinal block anesthesia in obese patients.Method: This reviewed study was carried out by doing search in Scholar Google, PubMed and Elsevier databases using keywords such as spinal block, body mass index and obese patients. Approximately 26 articles were selected that were fully reviewed.Results: our results were obtained on the results of the reviewed articles. Therefore, Sensory and motor blocks recovery time were longer in the obese patientsConclusion: Based on the result, there are correlation between BMI and the time of spinal block anesthesia. The maximum motor and sensory block specified in obese patients happens faster and the analgesic duration could be prolonged in patients with a higher BMI.
