Comparison of Hemidiaphragmetic paralysis in supraclavicular and infraclavicular brachial plexus block

Phase 3

Not yet recruiting

Conditions: Acute embolism and thrombosis of veins of upper extremity, (2) ICD-10 Condition: I872||Venous insufficiency (chronic) (peripheral),

Registration Number: CTRI/2024/09/074293

Lead Sponsor: JSS ACADEMY OF HIGHER EDUCATION AND RESEARCH

Brief Summary: Following approval from the Institutional Ethical committee,

Patients will be evaluated for the eligibility of the study , and written informed consents will be obtained from enrolled participants by the study team before surgery .

A thorough pre anesthetic evaluation will be done 24 hrs prior to the procedure.

Patients will be randomly assigned using shuffled sealed ,opaque enveloped technique at

ratio of 1:1into two groups .

GROUP (SC)- Supraclavicular brachial plexus block

GROUP(CC)- Costoclavicular block

ANESTHETIC PROCEDURES

Patients in the age group of 20-60 of either sex undergoing elective basilic vein

transposition under brachial plexus block will be enrolled for the study with written

informed consent

On the day of surgery, a single anesthesiologist performs either the supraclavicular or

infraclavicular block. Prior to 30 minutes of surgery sonographic assessment of diaphragm

motion and contraction will be done using â€œABCDE â€œ method described by Tsui et all(2).Which is performed by placing the probe at zone of apposition of anterior Axillary line,

watching for breathing (lung sliding), then moving caudally to identify the diaphragm for

evaluation . An 20 G iv cannula will be inserted and the patient is connected to standard

monitors such as noninvasive blood pressure , electrocardiography [ECG] and pulse

oximetry[Sp02].

All blocks will be performed under ultrasound guidance (Logiq p6 pro ultrasound system

manufactured by GE healthcare) by a single experienced Anesthesiologist using linear

probe of frequency 15-20 hz (11L) at different locations . Each patient will be

administered mixture of 22 ml, out of which 10 ml is 0.5% Bupivacaine , 10ml is 2%

lignocaine with adrenaline. , Dexamethasone 4mg (1ml) and clonidine 150mcg. .

Adequacy of sensory and motor blockade will be assessed .After about 30 minutes of

observation the movement of Diaphragm will be assessed using Ultrasonography by

using the â€˜ABCDE teqnique. Patient satisfaction and complications like vascular puncture

and pneumothorax will be assessed.
