landmark-based superficial cervical block is used. After insertion of the needle superficially below the skin, 20 to 30 ml of 4.75 mg/ml ropivacaine are injected fan-like in the subcutaneus plane.
ultrasound-guided intermediate cervical block was performed. The probe is placed perpendicular to the skin, in the horizontal plane at the C3-C4 level. Needle is inserted in-plane. 10 ml ropivacaine 4.75mg/ml are injected under ultrasound control, 5 ml injected when needle is withdrawn under ultrasound control, 5 ml in the subcutaneous plane.
