The site of brachial plexus block needle anesthesia

Brachial plexus block anesthesia is one of the nerve block anesthesia, belongs to local anesthesia. Anesthesiologists choose different puncture sites according to different surgical sites of patients, including intermuscular sulcus, armpit, supraclavicular, subclavicular, etc. Different puncture sites are selected, and the block anesthesia sites are slightly different, but generally speaking, they are used to anesthete the upper limbs.

For example, the intermuscular sulcus, a nerve block at the middle posterior margin of the sternocleidomastoid muscle, can be used to perform a portion of the upper arm including the shoulder joint. For hand surgery, axillary nerve block anesthesia is generally chosen. Generally speaking, the onset time of brachial plexus anesthesia is 10-20min, and the onset time is different for different ages. Older people work faster, younger people work slower. Older people work faster, but for longer than younger people. This is because the elderly are highly sensitive to local anesthetics.
