The Success Rate Of Radial Nerve And Ulnar Nerve Block With Ultrasound Compared To Without Ultrasound For Pain Management In Emergency

Background: One of the most important duties of an emergency medicine specialist is pain management. Patients with hand trauma come to the emergency room with severe pain. Therefore, the purpose of this study was to determine the success rate of radial, ulnar, and median nerve blocks with and without ultrasound guidance for pain management in the emergency room. Methods: In this clinical trial study, ۲۸۶ patients with isolated hand trauma were divided into two groups using a table of randomization numbers. In one group, the desired nerve block was performed under sterile conditions and with a guide probe surface ultrasound, and in the other group, the location of the nerve was determined through landmarks and under sterile conditions, the desired nerve block was performed. Data analysis was done using spss software version ۲۱ and using descriptive and inferential statistical tests. Result: The average age of the studied patients was ۲۶.۳ ± ۳ years. The frequency distribution of successful nerve block was ۸۵.۳% in the group with ultrasound guidance and ۶۷.۸% in the group without ultrasound guidance (P=۰.۰۰۲). There was no significant difference in the frequency distribution of patient satisfaction in the two study groups (P=۰.۶۲۲). The frequency distribution of nerve block success in both sexes was not significantly different (P=۰.۹۷۱). The frequency distribution of nerve block success based on the blocked nerve was not significantly different (P=۰.۱۳۸). Conclusion: The use of ultrasound to create a nerve block in the procedures performed on the hand in the emergency room increases the accuracy and success of the nerve block and as a result reduces the complications and dissatisfaction of the patients.
