Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Many studies have compared the effects of upper extremity peripheral nerve blocks on the onset, quality, extent, and postoperative pain of sensory and motor block through axillary, infraclavicular, supraclavicular and interscalene approaches.
The aim of this study is to measure the effects of sympathetic blockade caused by peripheral nerve blocks performed with the axillary, infraclavicular and interscalene approach on tissue oxygenation with Near Infrared Spectroscopy (NIRS), to evaluate and compare the radial artery flow velocity and diameter in the blocked extremity, and to investigate whether there is a relationship with the quality of the sensory and motor block.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Axillary Brachial Plexus Block
Our study includes 3 groups, 33 patients each who underwent axillary, infraclavicular and interscalene blocks. In the study, which of the axillary, infraclavicular and interscalene blocks will be preferred, will be decided by an experienced anesthesiologist in accordance with the type of surgery to be performed. Demographic data, comorbidities, and smoking will be questioned in each group, arterial blood pressure, heart rate, body temperature, radial artery diameter and flow velocities will be recorded before peripheral nerve block is applied, and tissue oxygenation will be measured with Near Infrared Spectroscopy (NIRS) in the extremities with and without block. Tissue oxygenation, radial artery flow velocity and diameters, body temperature will be measured simultaneously at 0(basal)-5-10-15-20-25 and 30th minutes after the application of the block. test will be applied and the success of the procedure will be determined accordingly.
Near Infrared Spectroscopy (NIRS)
After the brachial plexus block, the regional oxygen saturation (rSO2) was monitored for 30 minutes with the Regional Oximetry System (O3™, Masimo, Irvine, CA) and the radial artery diameter with ultrasound in the same period.
Infraclavicular Brachial Plexus Block

In the study, which of the axillary, infraclavicular and interscalene blocks will be preferred, will be decided by an experienced anesthesiologist in accordance with the type of surgery to be performed.
