¡¡¡¡Abstract:Objective To provide the anatomical data concerned with plexus cervicalis anaesthesia for the clinical anesthetist.Methods The lateral cervical area of28adult corpses£¬18ma1e and10female£¬were dissected and6data concerned with clinical aesthesia through plexus cervica-lis were measured with a ruler and a vernier caliper.The collarbone head of sternomastoid muscle was named as A£¬the lowest point of mastoid pro-cess of temporal bone as B£¬the midpoint of plexus cervicalis superficial branch out of posterior margin of sternomastoid muscle as O£¬the costal tuber-cle of the4th transverse process of cervical vertebra as C4 .Results The length of AB line was(12.6±1.1)cm£¬the distance of OB was(6.8±0.6)cm£¬the distance of C4 B was(6.5±0.8)cm£¬the shortest distance of skin(S)to O was(0.8±0.1)cm£¬the shortest distance of SC4 was(2.0±0.2)cm.Conclusion In performing the plexus cervicalis block anaesthesia£¬the region of injection should be within(6.8±0.6)cm from the posterior margin of sternomastoid muscle to the lowest point of the processus mastoideus£¬and the depth of injection should be(0.8±0.1)cm for
