A comparison of pneumotorax and phrenic nerve pulsy complications using the methods: supraclavicular nerve block, routine and ten degree cephalic route

Abstract

Background: Supraclavicular nerve block is a method for upper limb surgery in Anesthesiology. In this method that is common for supraclavicular block, injection anesthesia on the first rib and it has complications such as pneumothorax, phrenic never pulsy, infection, intra spinal injection. In this study injection with a 10 degree cephalic side as compared with the first rib in order to decrease of complications was evaluated. Materials and methods: In this research with a interventional study on 100 patients injection was done with a 10 degree cephalic side to the first rib and incidence of these complications is 0% in the Z-test the statistical difference is significant. Results: Results showed that there was no any case of peneumothorax and phernic nerve pulsy, although these complications were 6% and 60% in control group. There was significant in two groups using Z-test (p<0.0001). Conclusions: Therefore in this method, incidence of pneumothorax and phrenic never pulsy is decreased. Suggested that this method and the other methods compare and use this method with more confidence.
