Brief summary

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

Detailed description

The aim of the study is to assess the effect of hemi-diaphragmatic paresis following ultrasound-guided erector spinae plane block.

Interventions

OTHERESP block

ESP block performed using ultrasound guidance. Diaphragmatic excursion was measured using M-mode ultrasound during normal breathing, deep breathing and with the sniff manoeuvre.
