Abstract
we aimed to determine the effect of some anthropometric values on sensorial block characteristics of spinal anesthesia and hemodynamics in patients undergoing elective cesarean sections performed under spinal anesthesia. Weight, length, and body mass index ,waist and hip circumferences ratio of 200 patients were measured. Spinal anesthesia was applied while the patient was sitting erect. The time of sensorial block to reach the T4 level and the maximum sensorial block level were recorded in each case. Cases who developed hypotension and bradycardia during the spinal anesthesia were recorded. In this study hypotension was observed in 54% of patients and it was determined that the prevalence of hypotension increased in patients with a higher body mass index, a higher waist/hip ratio. It was found that the prevalence of bradycardia increased in patients with a higher body mass index and a higher waist/hip ratio. This study also determined a positive correlation between the values of height, weight 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 In line with the values provided by simple and non-time consuming anthropometric measurements the patients who are planned to receive a spinal anesthesia may be priorly prepared against adverse effects of bradycardia and hypotension that may develop, and to estimate the sensorial block characteristics of the spinal anesthesia.
