Erector Spina Muscle Distance From the Skin at Different Thoracal Elevations

1- Abstract Introduction Erector spina plana block can be performed in different positions (sitting-lateral-pron) and at different thoracic levels. In our study, we aimed to calculate the ideal measurement of the distance of the erector spina muscle to the skin and to find the best ultrasonography image at different thoracic levels (T1-T2, T5-T6, T5-T6, T11-T12) and in other positions (lateral-sitting-pron) to improve the quality of the block in patients who will undergo erector spina plan block. Material and Methods A total of 80 patients (40 females and 40 males, ASA I-II) aged 18-65 years were included in the study. The erector spinae muscle was determined at T1-T2, T5-T6, and T11-T12 levels and in lateral, sitting, and prone positions, respectively, with a high frequency 10-15 millihertz linear probe of ultrasound, The distance from the skin to the midline of the ultrasound screen was measured, and the best ultrasound screen image was recorded. Erector spina plan block, distance measurement, different positions, interfascial plan block.
