Objective: We aimed to determine the effects of anthropometric values; body mass index, body surface area, abdominal circumference, and waist/hip ratio on sensorial block characteristics of spinal anesthesia and hemodynamics in patients to undergo cesarean sections performed under spinal anesthesia. Material and Method: 50 cases aged between 18-35, who would undergo elective cesarean section were included in the study. Weight, length, body surface area, and body mass index, abdominal, waist, and hip circumferences of the patients were measured. Spinal anesthesia was applied with 10mg hyperbaric bupivacaine HCL. The time of sensorial block to reach the T4 level and the maximum sensorial block level were recorded in each case. Cases developing hypotension and bradycardia during the spinal anesthesia were recorded. Results: In our study conducted based on anthropometric measurements; hypotension was observed in 54% of patients and it was determined that the prevalence of hypotension increased in patients with a shorter height, larger abdominal circumference, higher body mass index, lower body surface area and a higher waist/hip ratio. It was found that the prevalence of bradycardia increased in patients with a shorter height, higher body mass index, lower body surface area and a higher waist/hip ratio. This study also determined a positive correlation between the values of height, weight and body surface area and the time of sensorial block to reach the T4 dermatome; and a positive correlation between the body mass index and the dermatome area of the maximum sensorial block. Conclusion: It is suggested to be prepared more against bradycardia and hypotension that may develop in accordance with the values to be given by simple and non-time consuming anthropometric measurements in patients who are planned to receive a spinal anesthesia, and to estimate the sensorial block characteristics of the spinal anesthesia.
