To assess the incidence of hemi-diaphragmatic paresis following ultrasound-guided erector spinae plane (ESP) block

The ultrasound (USG) guided ESP block was first defined in 2016. With the administration of local anesthesia between the transverse process of the vertebra and the erector spinae muscle, it is stated that the effect mechanism of ESP is that spread blocks the ventral and dorsal rami to the paravertebral area. The aim of the study is to assess the incidence of hemi-diaphragmatic paresis following ultrasound-guided erector spinae plane block.
