Serratus anterior fascia plane block for pain control in patients with multiple rib fractures

抄録

[Purpose] Respiratory physiotherapy plays an important role in the management of acute respiratory disturbance; however, chest pain often impedes patients from performing respiratory physiotherapy. In this study, we investigated whether pain due to multiple rib fractures can be managed with intermittent serratus anterior fascia plane (SAP) block. [Participants and Methods] We performed intermittent SAP blocks in three consecutive patients with pain due to multiple rib fractures based on the level of pain. The level of pain and differences in expiratory/inspiratory chest expansion were evaluated before and after performing the SAP block. [Results] All three patients reported an improvement in the severity of pain and increase in the thoracic range of motion after receiving the SAP block. No adverse events associated with intermittent SAP blocks were observed in any of the patients. [Conclusion] We report the cases of three patients who completed respiratory physiotherapy after receiving intermittent SAP blocks for the management of pain due to multiple rib fractures. SAP blocks are associated with a low risk of complications as the ribs are not punctured while performing SAP blocks.
