Based on a review of medical records at a large university hospital, which of the following best describes the risk of major vascular or neurological complications arising from perioperative arterial cannulation?
Arterial cannulation is frequently performed with anesthesia for major surgery to provide beat-to-beat blood pressure monitoring and access for intermittent laboratory sampling. Arterial cannulation is generally safe and effective, but complications have been reported. These include embolic or ischemic events, transient or permanent neurologic injury, and catheter-related infections. Previously described risk factors include the site of cannulation, the size of the catheter and the duration of monitoring.
A recent retrospective review of medical records from the Mayo Clinic described a search for complications related to perioperative arterial cannulation. More than 88,000 arterial line procedure notes were retrieved from the electronic health care record from 2006 through 2012. After eliminating arterial cannulation in pediatric patients, non-operating room cases and patients not consenting for inclusion of their records, the authors screened 62,626 arterial lines in 57,787 patients for any subsequent evidence of vascular or neurosurgical consultation, documented infection, or unplanned return to surgery. Finally, 2,609 medical records were individually reviewed by the research team, eventually confirming only 21 major vascular or neurological complications attributable to the arterial cannulation, for a rate of just 3.4 per 10,000 lines or 3.6 per 10,000 patients (approximately 1 in 3,000 lines or patients).
