Incidence and Clinical Significance of Hemidiaphragmatic Paresis in Patients Undergoing Carotid Endarterectomy During Cervical Plexus Block Anesthesia

Ropivacaine 3.75 mg/ml, 5 mg/ml, or 7.5 mg/ml for cervical plexus block during carotid endarterectomy

“…Moreover, phrenic nerve paralysis can compromise respiratory function in disabled patients. 7,8 Ropivacaine was selected because it is reported to possess a higher threshold for systemic toxicity, which offers the benefit of an increased therapeutic margin in case of intravenous resorption. 10 Currently, information about ideal ropivacaine concentration for cervical plexus block is not available.…”

Continuous cervical plexus block for carotid body tumour excision in a patient with Eisenmenger's syndrome

“…Concerns about the risk of phrenic nerve palsy [39,40] and consequent respiratory impairment with cervical plexus block were addressed by the intermittent infiltration of local anaesthetic via the catheter. Utilizing this method provided flexibility and, we believe, reduced the risk of phrenic nerve palsy and local anaesthetic toxicity [41] in comparison to the standard technique [1].…”

Bilateral superficial and deep cervical plexus block for thyroidectomy in pregnancy

“…4 Although it provides better anesthesia, deep cervical plexus block is technically more difficult to perform and may be associated with more serious complications than superficial cervical plexus blocks alone. 5 An ultrasound-guided block has less risk, 6 but unfortunately we did not have access to this device.…”
