Comparison of Supraclavicular and Costoclavicular Brachial Plexus Blocks in Adult Patients

Comparison of Diaphragma Thickness and Perfusion Index Change in Supraclavicular and Costoclavicular Brachial Plexus Block in Adult Patients Undergoing Hand Surgery

Hemidiaphragmatic paresis is a common side effect of brachial plexus blocks such as supraclavicular or infraclavicular block techniques. It has been shown that diaphragma thickness is affected at some extent in supraclavicular block and also in costoclavicular block which is accepted as an infraclavicular approach. However, these two approaches have not been extensively investigated before in terms of the diaphragmatic paresis. Here, it is aimed to compare these two methods considering their effects on diaphragma thickness in inspirium and in expirium. Moreover, the performance properties such as motor and sensory block onset, needle visualization time, needle visualization difficulty, postoperative pain scores, and lastly the perfusion index which is known to be reflecting vasodilation will be investigated.
