Study hypothesis
Carotid endarterectomy is performed in patients with severe stenosis (narrowing) of the carotid arteries. The operation improves blood supply to the brain and reduces the risk of stroke in selected patients. In the early post operative period following carotid endarterectomy patients commonly develop blood pressure lability. It is our observation that severe hypertension has decreased whilst hypotension requiring treatment has increased in our patient group over the past 2 years. Two changes in our practise may be contributing to this - first the majority of patients are now beta blocked, secondly our patients are now commonly given a superficial cervical plexus block. We aim to establish the influence of superficial cervical plexus blockade on post operative blood pressure control in these patients.
Our null hypothesis is that there is no clinically significant difference in the mean blood pressures in the first 24 hours following carotid endarterectomy in patients who have been given a superficial cervical plexus block and those who have not.
Ethics approval
Ethics approval received on the 22nd July 2004; amendment approved 27th May 2005 (ref: 04/Q1001/21).

Laevo-bupivacaine
Primary outcome measure
Mean systolic blood pressures over the first 24 hours postoperatively.
Secondary outcome measures
1. Need for antihypertensive treatment
2. Need for pressor treatment
3. Cumulative dose of any vasoactive medication
4. Mean pain scores
5. Cumulative opiate requirements
Any cardiovascular, cerebrovascular or other major morbidity or mortality occuring during the time period and any complication potentially related to the superficial cervical plexus block will also be recorded.
