Safety and efficiency of ultrasound-guided intermediate cervical plexus block for carotid surgery

摘要: Abstract Objective Since stroke and myocardial ischaemia are major causes of perioperative morbidity mortality associated with carotid endarterectomy, monitoring the brain ensuring best haemodynamic stability important goals management. As regional anaesthesia was reported to improve during endarterectomy (CEA), we conducted a prospective observational study on efficacy safety ultrasound-guided intermediate cervical plexus blocks (CPB), early (immediate postoperative) mid-term (day 30) outcomes in awake patients undergoing CEA. Methods After ethics committee approval, 50 CPB from April 2011 May 2013 were included. Anaesthesia surgical dissection parameters, complications recorded, as well neurologic cardiac initially one month later. Results Cervical space easy locate by ultrasound 90% patients. The quality good 86 88% patients, respectively. No conversion GA required, secondary lack analgesia. Two (4%) had severe hypotension ( −1 ) without ECG change 1 death occurred after postoperative haemorrhagic stroke. Conclusions present work reports our first cases using guidance. results underline that this technique is perform, safe reliable, provided conditions continuous intraoperative stable haemodynamics respected.
