Continuous erector spinae plane block for analgesia and better pulmonary functions in patients with multiple rib fractures: a prospective descriptive study

Background : The present study explored the role of continuous erector spinae plane (ESP) block for analgesia as well as its impact on pulmonary functions in patients with multiple rib fractures. Methods: Ten patients with multiple rib fractures were enrolled after getting informed and written consent. Ultrasound-guided ESP block was performed at the level midway between the fractured ribs followed by the insertion of the catheter. Pre- and post-block VAS score, hemodynamics, respiratory rate (RR), peripheral oxygen saturation (SpO(2)), inspiratory capacity (IC), blood gases (PaO2 and PCO2), and complications were compared. Results: Pain scores at rest as well as on movement showed a significant reduction from 5.9 and 7.5 pre block to 1.6 and 2.5 respectively at 96. hours (p <. 0.0001). Similarly, RR, SpO(2), IC, and PaO2 were significantly better after the block placement (p <.0.001). Conclusion: Continuous ESP block provide adequate analgesia with better respiratory functions in patients with multiple rib fractures.
