简要总结
We propose to compare the effects of local anaesthetic dilution on the characteristics of the ultrasound guided axillary brachial plexus block.
Administration of 40ml lidocaine 1% with epinephrine will shorten the onset time of ultrasound guided axillary brachial plexus block when compared to 20 mL lidocaine 2% with epinephrine for elective upper limb surgical procedures.
详细描述
To compare the effects of local anaesthetic 20 mL lidocaine 1% with epinephrine vs 40 mL lidocaine 1% with epinephrine on the onset of sensory and motor block following ultrasound guided axillary brachial plexus block.
Methods:
It is a prospective, randomized, observer blinded study. With institutional ethical approval and having obtained written informed consent from each, 20 patients will be studied.
Randomisation and blinding:
Using a computer generated and sealed envelope technique, 20 patients will be randomly allocated in to one of two groups.
