Ultrasound Guided Retroclavicular Infraclavicular Versus Axillary Block as Regional Anesthesia in Obese Patients

Ultrasound Guided Retroclavicular Infraclavicular Versus Axillary Block as Regional Anesthesia in Obese Patients Undergoing Around and Below Elbow Surgeries: A Randomized Clinical Study

• Status: Enrolling By Invitation
• Phase: N/A
• Study type: Interventional
• Enrollment: 90 (estimated)
• Sponsor: Zagazig University · Other Government
• Sex: All
• Age: 21 Years – 45 Years
• Healthy volunteers: Not accepted

Summary

The purpose of this study is to compare the analgesic outcomes (time to first analgesic request, total amount of analgesic consumption, and pain scores) following the ultrasound-guided retroclavicular infraclavicular approach and the axillary approach in obese patients.

Conditions

• Achievement of High-quality Analgesia in Elbow Surgeries

Interventions

Type	Name	Description
OTHER	retroclavicular infraclavicular brachial plexus block for	The patient will be placed supine, head facing the contralateral side. A high- frequency 13-6 MHz linear array transducer probe will be placed medial to the coracoid process below and perpendicular to the clavicle to obtain a short-axis view of the cords of the brachial plexus and the axillary vessels. The needle will be inserted in the supraclavicular fossa, approximately one cm posteriorly to the clavicle, and advanced in plane parallel to the probe. After passing the initial blind zone of about 2 cm caused by the clavicle's acoustic shadow, the needle tip will be continuously seen, until it appears posterior to the axillary artery. A single injection of the local an esthetic will be performed without needle repositioning unless paresthesia is elicited
OTHER	axillary block	The axillary nerve block is performed from behind the patient with the patient seated. The axillary nerve will be identified within the quadrilateral space by placing high frequency linear probe parallel to the long axis of the humeral shaft. The nerve was identified next to the circumflex artery
