In Subclavian Vein Catheterization Using the Infraclavicular Approach, the Following

In subclavian vein catheterization using the infraclavicular approach, the following problems may occur, even when great care is exercised: (a) The needle may hit the clavicle; (b) the needle may hit the first rib; (c) the needle may hit the subclavian artery. How would you deal with these problems?
the body for taking the pulse, the following arteries are easily palpable: The pulsating facial artery can be felt as it winds around the lower margin of the mandible in line with the anterior border of the masseter muscle (see text Fig. 6-10). The superficial temporal artery may be palpated in front of the auricle of the ear as it ascends over the zygomatic arch (see text Fig. 6-1). The classical site for feeling the pulse in the neck is along the anterior border of the sternocleidomastoid muscle at the level of the upper border of the thyroid cartilage (see text Fig. 6-3). Here, the common carotid artery divides into the external carotid and internal carotid arteries, and all three are quite superficial at this location.
