We review the study by Xu et al. (J Clin Monit Comput 37(4):985-992, 2023. https://doi.org/10.1007/s10877-022-00968-1 ) on ultrasound-guided regional blocks in clavicle surgery, assessing the effects on anaesthesia and postoperative outcomes. However, there are concerns. The defined population of the study differs from the registered title (Xu et al. J Clin Monit Comput 37(4):985-992, 2023. https://doi.org/10.1007/s10877-022-00968-1 ). In particular, the authors did not specify fracture types (Xu et al. J Clin Monit Comput 37(4):985-992, 2023. https://doi.org/10.1007/s10877-022-00968-1 ). In addition, the method of measuring the diaphragm is not clear (Xu et al. J Clin Monit Comput 37(4):985-992, 2023. https://doi.org/10.1007/s10877-022-00968-1 ). This affects the accurate interpretation of their results.
