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

Abstract

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 (SpO₂), 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, SpO₂, 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.
