| dc.description.abstract | The aim of this study was to determine the relationship between body mass index and hemodynamic changes during changing from prone to supine at the end of lumbar discectomy surgery.
Materials and Methods: In this cross-sectional study, a total of 80 patients in three groups by BMI (18.5-24.9, 25-29.9, >30) undergoing lumbar disc surgery was included. At the end of the surgery, the patient's systolic and diastolic blood pressure, heart rate, respiratory rate per minute, and Sat O2 measured by the operating room monitoring sphygmomanometer. Then patients were transferred to the supine position, and the patient's systolic and diastolic blood pressure, heart rate, respiratory rate per minute, and Sat O2 were measured immediately and at 5 and 10 minutes after the change in position.
Results: A statistically significant relationship between BMI and systolic and diastolic blood pressure wasn't observed immediately before the change of position (p <0.05); However, at 5 and 10 minutes after the change of position, the mean arterial blood pressure in BMI above 30 was significantly higher than BMI between 18.5 and 24.9 (p=0.002 and 0.023, respectively). Also, in the time before the change of position, 5 and 10 minutes after the change of position, the median diastolic blood pressure in BMI above 30 was significantly higher than BMI between 18.5 and 24.9 (p=0.002 and 0.022 and 0.028, respectively). | en_US |
