Comparison of the radial artery catheterization success rates of first-year anesthesia residents who had or had not received ultrasonography practice. 2022-08-19 anticipated 320 Complete https://irct.ir/trial/63947 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients are selected for each resident by available sampling method. Patients are assigned to one of the two methods of palpation and radial artery catheterization based on the randomization sequence prepared using PASS software using the randomization method with permutation blocks with a block size of 4 with allocation (2x2). In randomization, each resident is considered as a stratum. Allocation of patients with this method will be done by an anesthesiologist who will not be involved in the next stages of the research and before the patient enters the operating room by opening the non-transparent sealed envelope containing the name of the group, Blinding description: An anesthesia technician, who will not play a role in the research, will open an opaque sealed envelope based on a random sequence generated by the software during the patient's admission to the operating room and inform the responsible anesthesiologist. The anesthesiologist will call the resident associated with the patient group to perform catheterization and record the results of the resident's work. Then, without informing the main researcher, this information will be delivered to the statistical consultant of the project to be recorded in the statistical software. N/A Increase the success rate of radial artery catheterization. Intervention 1: Intervention group: Ten residents who each experienced ultrasound-guided catheterization in 16 patients in the first phase of the study will use the palpation method of radial artery catheterization in 16 other patients. Intervention 2: Control group: Ten residents who each experienced the use of the palpation method in 16 patients in the first phase of the study will again use the palpation method for radial artery catheterization in 16 additional patients. Yes - There is a plan to make this available What will be shared: All data is potentially shareable after unidentified individuals. When: One year after the publication of the article. To whom: All jobs Conditions: All non-personal patient information (anonymously) can be accessed by contacting the responsible author.

Success rate in the first attempt. Timepoint: The first 5 minutes of catheterization. Method of measurement: Measuring time and observing the success of anesthesia resident performance in radial artery catheterization by an anesthesiologist. Final success rate. Timepoint: During catheterization time. Method of measurement: An anesthesiologist observes the performance of the anesthesia resident. The time taken to complete the catheterization. Timepoint: During catheterization time. Method of measurement: Measurement with a stopwatch by an anesthesiologist.
