简要总结
The aim of this prospective, randomised, controlled study is to compare the efficacy of ultrasound-guided intermediate cervical block to superficial block for carotid endarterectomy.
Patients scheduled for carotide endarterectomy under regional anaesthesia (ropivacaine 4.75 mg/ml) are randomised into 2 groups according to the technique of anaesthesia performed: superficial cervical block (Control group) or, ultrasound guided intermediate cervical block (Echo group). Main outcome is cervical block success, defined by surgery performed under regional anaesthesia without supplemental topical lidocaine. Secondary outcomes are rate of conversion to general anaesthesia, total dose of supplemental topical lidocaine and block-related complications.

研究组 & 干预措施
control group
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.
干预措施: landmark based superfical ropivacaine 4.75 mg/ml injection (Other)
echo group
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is inserted in-plane. 10 ml ropivacaine 4.75mg/ml are injected under ultrasound control, 5 ml injected when needle is withdrawn under ultrasound control, 5 ml in the subcutaneous plane.
干预措施: Ultrasound-guided administration of ropivacaine 4.75 mg/ml (Other)
