About

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.

50 participants in 2 patient groups

Costoclavicular block

Active Comparator group

Description:

Patients who will receive costoclavicular brachial plexus block for hand surgery. Costoclavicular block is performed via depositing local anesthetic in the costoclavicular space which is placed in the posterior of middle part of the clavicle. The diaphragma thickness will be evaluated after the surgery in postanesthesia care unit.

Treatment:

Diagnostic Test: Ultrasonographic measurement of diaphragm thickness

Supraclavicular block

Active Comparator group

Description:

Patients who will receive supraclavicular brachial plexus block for hand surgery. Supraclavicular is performed via depositing local anesthetic using corner pocket technique which is described as injecting the drugs to the inferolateral side of axillary artery above the 1st rib. The diaphragma thickness will be evaluated after the surgery in postanesthesia care unit.

Treatment:

Diagnostic Test: Ultrasonographic measurement of diaphragm thickness
