Brief summary
Objective: To investigate the effect of lidocaine injection location on the success rate of ultrasound-guided radial artery catheterization in a single-center, randomized, controlled clinical trial.
Detailed description
Group A was randomly divided into two groups: 1% lidocaine 1 ml was injected above the artery during local anesthesia before arterial catheterization; Group B: 1ml of 1% lidocaine was injected into the right side of the artery. The proportion of subjects according to the number of PO was similar in all groups. After the screening, the scientific research personnel of each testing center will log in the random system, fill in the screening information, obtain the random number information, and distribute the corresponding scientific research drugs according to the random number. The total number of drugs is imported into the centralized random grouping system by generating random number by SAS software. The study was conducted by an evaluation researcher and a medication management researcher. Throughout the experiment, not only the subjects turned a blind eye, but also the evaluators turned a blind eye. This study set up evaluation investigators and administrative investigators. Administrative researchers were only involved in the randomization, allocation, and delivery process. Other procedures, including informed consent, screening, efficacy index and safety evaluation, and planned visits, were completed by the evaluation investigators.
