on our recently published study on the serratus anterior plane block in the treatment of multiple rib fracture pain. 2 We are convinced that the trauma patients consider the NRS reduction of two to be clinically significant, and this assumption is supported by literature. 3 With visual analogue scale postoperative patients 10 mm may be sufficient. 4 Blunt trauma patients often have multiple injuries. 5 In our study all the patients except two had also other injuries than rib fractures influencing rescue opioid use.In this study design, we asked patient satisfaction in 1 h because at that time point, the patients were able to evaluate specifically the effect of the block. At a later stage the pain caused by other injuries and the use of PCA are confounding variables. Dorsal thoracic wall blocks may be good option, especially with dorsal fractures, but necessitate more challenging positioning compared with SAB. Also, paravertebral block is considered to be a deep block with same guidelines for anticoagulation that would be used for neuraxial anesthesia. 6 We totally agree that more clinical studies are needed for this subject.
