Placed some a-lines today. Decided I really don't like the Arrow kits (the one with the wires) First one I tried three times with the arrow, no dice. One try with the old-school jelco, bingo. Second time, facilitor wanted me to try placing it with the doppler on an awake patient. No luck. Jelco and palpation, perfect on the first try. Are some of you senior residents and attendings big jelco fans?
