ADVERSE REACTIONS, ADVERSE EFFECTS
Clavicular fracture is one of the most common clinical fractures, and incision reduction internal fixation surgery is the main treatment method [At present, ultrasound-guided superficial cervical plexus combined with brachial plexus block is the most widely used method in clinical practice [In recent years, ultrasound-guided interfascial plane block has been widely used for regional anaesthesia and pain management of the trunk [The inadequacies of this study are as follows: first, this study did not discuss the optimal concentration and volume of local anaesthetics for superficial cervical fascial block; second, invasive arterial blood pressure monitoring was not performed; third, the ultrasound contrast monitoring of diaphragm movement was not performed, and the observation of dyspnoea was used to assess whether the sensitivity of the phrenic nerve block was poor, especially for patients with good cardiopulmonary function. In addition, the sample size seems insufficient to detect any adverse effects. Ultrasound-guided nerve block methods cause very few adverse reactions. Therefore, such reactions were not considered for this test, which is a shortcoming of this article, and further research is needed in the future. The scheme provided by this experiment shows obvious advantages, and future research requires more sophisticated methods for further in-depth research.
