Chapter 66. Regional Anesthesia and Perioperative Outcome
One outcome advantage of regional anesthesia over general anesthesia involves:
A. Higher billing compliance
B. 10 times lower rate of prostate cancer
C. Elimination of anesthesia-induced metastatic brain cancer
D. Reducing the hypothalamic-pituitary-adrenal axis activation and subsequent immune suppression
D is correct. General anesthesia is worse from an oncologic standpoint when compared to sedation or regional anesthesia.1
Pain itself has what impact on the immune system?
A. Counteracts opioid-induced immune suppression
B. Suppresses natural killer (NK) cell function
C. Reduces immune-related cancer metastasis
D. Possesses cytotoxic properties
B is correct. Pain suppresses NK cell function.2
Epidural for thoracotomy surgery has what affect post-procedure?
A. Significantly lower rates of post-thoracotomy pain at 6 months post-procedure
B. Slightly lower rates of post-thoracotomy pain at 6 months post-procedure
C. Thoracotomy pain is not affected after 1 month post-procedure.
D. Thoracotomy pain decreases initially in the first week and then remains the same.
A is correct. Epidural has a both a short-term and long-lasting advantage when used for thoracotomy.3
Some economic benefits of regional anesthesia are:
A. Larger bundled payments
B. Higher billing compliance
C. Both shorter length of hospital stay and lower resource utilization
D. Quicker time to rehabilitation facilities and shorter turnover time
C is correct. Hospitals and patients benefit from regional anesthesia as length of stay and resource utilization goes down.4
Major perioperative outcome improvements related to regional anesthesia include:
A. Decreased rate of mechanical ventilation and blood transfusion
B. 10 times lower rate of deep vein thrombosis
C. Shorter stay in rehabilitation facilities
D. Decreased number of aneurysm ruptures
A is correct. With regional anesthesia, decreased blood loss from a sympatholytic effect occurs, and there is better pulmonary function, which ...
