摘要: Carotid endarterectomy is commonly conducted under regional (deep, superficial, intermediate, or combined) cervical plexus block, but it not known if complication rates differ. We a systematic review of published papers to assess the rate associated with superficial (or intermediate) and deep combined plus superficial/intermediate). The null hypothesis was that were equal. Complications interest were: (1) serious complications related placement (2) incidence conversion general anaesthesia, (3) systemic surgical-anaesthetic process. retrieved 69 describing total 7558 deep/combined blocks 2533 superficial/ intermediate blocks. Deep/combined block higher injecting needle when compared superficial/intermediate (odds ratio 2.13, P¼0.006). anaesthesia also 5.15, P,0.0001), there an equivalent other 1.13, P¼0.273; NS). conclude safer than any method employs injection. may have been influenced by direct complications, suggest provides better analgesia during surgery.
