Traditionally, infraclavicular as well as supraclavicular approaches to brachial plexus have been recommended for elbow surgery. Supraclavicular approach is considered to have a more rapid onset. However, investigators have noticed that the supraclavicular approach needs more supplementation if it is used for elbow surgery. Therefore more and more anesthesiologists now choose the infraclavicular approach for elbow surgery (though both approaches are recommended in the text books).~None of the published studies have addressed if one approach is indeed superior to the other specifically for elbow surgery. Therefore the investigators propose to undertake a study that will evaluate the two approaches to the brachial plexus specifically for elbow surgery.
This study compares the infraclavicular approach to supraclavicular approach of brachial plexus block for elbow surgery.
