Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Costoclavicular block

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.

Group Type ACTIVE_COMPARATOR

Ultrasonographic measurement of diaphragm thickness

Intervention Type DIAGNOSTIC_TEST

Lineer probe of the ultrasound machine will be placed sagitally on the level of 9th to 11th rib in order to observe diaphragmatic thickness change during a sniff. The thicknesses will be measured both in full expiration (Te) and full inspirium (Ti) in centimeters. The diaphragm thickness fraction will be calculated as follows: (Ti-Te)/Te

Supraclavicular block

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.
