Intervention / Treatment |
---|---|
Experimental: Blocked
All participants will have single-shot interscalene brachial plexus block with same technique.
There is no comparing.
|
For single shot-ISBP block, 15 ml of 0.5% bupivacaine + 10 ml of 2% prilocaine, a total of 25 ml of local anesthetic, will be administered to all patients. For the block procedure, an imaginary horizontal line drawn from the thyroid cartilage to the sternocleidomastoid (SCM) muscle will followed and the lateral of the SCM muscle will be cleaned with povidine iodine. At the C6 level to be blocked, the nerve roots will be detected by ultrasound. 25 ml of local anesthetic will be injected around the plexus roots with a 22 G 80 mm echogenic needle. The distribution of the local anesthetic applied to the area, which expands the tissues and separates the nerve roots from other tissues, will be seen on ultrasound. |

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Optic nerve sheath diameter change
Time Frame: Optic nerve sheath diameter will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute and change between basal and 20th minute will be assessed
|
Optic nerve sheath diameter will be measured as a unit of millimeter.
|
Optic nerve sheath diameter will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute and change between basal and 20th minute will be assessed
|
Internal jugular vein collapsibility index (IJV-CI) change
Time Frame: IJV-CI will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
|
IJV-CI will be measured as a unit of %.
|
IJV-CI will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
|
Maximum diameter of internal jugular vein (Dmax) change
Time Frame: Dmax will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
|
Dmax will be measured as a unit of millimeter
|
Dmax will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
|
Minimum diameter of internal jugular vein (Dmin) change
Time Frame: Dmin will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
|
Dmin will be measured as a unit of millimeter
|
Dmin will be measured before the block (basal) and it will be measured at 20th and 60th minutes after the block. The change between the measurements of basal and 60th minute, and change between basal and 20th minute will be assessed
