Prospective Observational Study Comparing GA and WALANT in Distal Radius Fracture Plating Surgery

1. Written informed consent must be obtained before any study-specific procedures are undertaken. 2. The process of the experiment A. Include participants into this study, they will be randomized into general anesthesia or WALANT group B. The maximum (toxic) dose of lidocaine was 7 mg/kg. Make distal radius fracture for an example, the solution used in the WALANT technique consisted of 20 ml of 2% lidocaine with epinephrine 1:50,000, which were mixed with normal saline to give a total of 40 ml. A set of baseline parameters, including pulse oximetry, respiratory rate, heart rate, blood pressure, respiratory rate, and oxygen saturation, was obtained during the entire surgery. At the same time, preoperative intravenous antibiotics with 1 g cefazolin were given for each patient as prophylaxis. The amount of blood loss was based upon the amount in a suction container in the operation room. In addition, the investigators will measure the participant's intraoperative subjective satisfaction and pain assessment. C. After surgery, the participant needs to stay in the in-patient department for one day. The investigators will provide routine prophylactic antibiotics and oral pain pillar. Postoperative pain, sensory, and motor function assessment.
