14 Medical Condition Being Studied

Musculoskeletal disease of the upper limb that require surgery under regional anesthesia

15 Intervention

i Types of intervention

Procedure

Please specify

ii Description/ name of Intervention/article

Ultrasound guided Costoclavicular Brachial Plexus block - single or multiple injection

iii Dosage form of the intervention

not a pharmaceutical study

iv Dosage of the intervention

not a pharmaceutical study

v Duration of the intervention

1 hour

vi Frequency of the intervention

once before operation

16 Comparative Treatments

i Description/ name of comparative treatments

This is a randomized study and there is a 50:50 chance of getting either one injection at the center of the three cords (Brachial plexus) via single skin puncture (Single injection) or have a single skin puncture and then the needle will be redirected under ultrasound guidance to inject the local anaesthetic close to each cord (a total of 3 cords) (Multiple injections). Multiple injections are expected to provide more rapid onset of surgical anesthesia and a higher proportion of patient achieving complete block than a single injection.

ii Dosage form of the comparative treatments

Not a pharmaceutical study

iii Dosage of the comparative treatments

Not a pharmaceutical study

iv Duration of the comparative treatments

1 hour

v Frequency of the comparative treatments

once before operation

23 Primary Outcome

i The Name of the outcome

The proportion of patient achieving complete block (both sensory score = 0 and motor score = 0)

ii The metric or method of measurement used

Sensory blockage (0-100), 100= normal sensation to cold, 0=no sensation to cold. Motorl blockade (3-point scale): 2=normal, 1=paresis, 0=paralysis.

iii The timepoint(s) of primary interest

At regular intervals for 50 minutes (5 min, 10min, 15min, 20min, 30min, 45min) after the block

24 Secondary Outcome

i The Name of the outcome

the time to complete blockade and time to readiness for surgery (sensory score ≤ 30 and motor score ≤ 1), block performance time, incidence of paresthesia during performing the block & complication of the technique; degree of discomfort experience by patient during injection

ii The metric or method of measurement used

Paresthesia (yes or no), & degree of discomfort (NRS: 0-100) experience by the patient during the injection.

iii The timepoint(s) of primary interest

After the block
