Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Therefore, the investigators tested whether ultrasound-guided peripheral nerve block enhanced the postoperative analgesia for upper extremity surgery compared with nerve stimulator (NS) guidance.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
NS-guided infraclavicular block
NS-guided infraclavicular block is performed using 35 ml of 0.5% ropivacaine.
NS-guided infraclavicular block
Patients received a standard single injection infraclavicular block using the lateral sagittal approach of Klaastad. The infraclavicular brachial plexus is identified using an insulated needle connected to a nerve stimulator. Placement of the needle is considered adequate if motor response of radial nerve in the hand or wrist is still present at 0.2 - 0.5mA. Ropivacaine 0.5% 35ml is used.
US-guided infraclavicular block
US-guided infraclavicular block is performed using 35 ml of 0.5% ropivacaine.
US-guided infraclavicular block
Infraclavicular block is performed under ultrasound guidance. Linear probe is placed in a parasagittal positon below the clavicle medial to the coracoid process and adjusted to achieve a cross-sectional image of the axillary artery. Using in-plane technique, an 22-gauge insulated needle is advanced caudally and posteriorly to the axillary artery. Subsequently, 35 ml of 0.5% ropivacaine is incrementally injected.
