简要总结
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.

结局指标
主要结局
Diaphragm thickness fraction (centimeters)
时间窗: Up to 4 hours
The formula is as follows: (Diaphragm thickness at the end of inspirium - Diaphragm thickness at the end of expirium)/ Diaphragm thickness at the end of expirium. This ratio gives the fraction of diaphragm thickness which reflects possible diaphragm paresis or paralysis. The thickness is measured during a sniff test via ultrasound for which the probe is placed sagitally on the level of 9th to 11th rib on the mid axillary line.
