Preoperative assessment

Preoperative assessment of the patient for regional anesthesia is similar to that for general anesthesia. The details of the procedure to be performed, including its anticipated length, patient position, and a complete review of any coexisting diseases, should be taken into account in determining the appropriateness of a regional technique.

The area where the block is to be administered should be examined for potential difficulties or pathology. Preexisting neurologic abnormalities should be well documented and the presence of kyphoscoliosis determined.

A history of abnormal bleeding and a review of the patient's medications may indicate a need for additional coagulation studies.
