Özet
Aim: The aim of the study was to assess whether spinal immobilization with long back board (LBB) and semi-rigid cervical collar (CC) at 20° instead of 0° conserves pulmonary functions in obese volunteers, including forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio. Methods: The study included adult volunteer subjects with android-type obesity who were otherwise healthy. First, pulmonary functions were tested in a seated position to obtain baseline levels, than volunteers were immobilized with LBB and CC at 0-degree and measurements repeated at 0th and 30th minute of immobilization. Next day, same procedures were repeated with the trauma board at 20-degree. Changes over time in FEV1, FVC values and FEV1/FVC ratios during spinal immobilization at 0° and 20° were compared to baseline levels. Results: Study included 30 volunteers. Results showed a significant decline in all values for both situations following spinal immobilization (p <.001). We also compared the decrease over time in those values (ΔFEV1, ΔFVC, and ΔFEV1/FVC ratio) during spinal immobilization at 0° and 20°. The decrease in pulmonary functions was similar in both groups (p >.05). Conclusion: The present findings confirm that spinal immobilization reduces pulmonary functions in obese volunteers, and that 20-degree immobilization has no conservative effect on these values when compared to the traditional 0-degree immobilization. It may be that 20° is insufficient to decrease the negative effect of abdominal obesity on pulmonary functions.
