Arterial Lines

Excerpt

Arterial lines are a critical component of hemodynamic monitoring in acutely ill and perioperative individuals, providing continuous blood pressure measurement and allowing for frequent arterial blood gas analysis. Commonly placed in the radial, femoral, or brachial arteries, these catheters offer real-time insight into a patient’s cardiovascular status, guiding resuscitation and vasopressor management. Despite their utility, arterial lines are associated with potential complications, including infection, thrombosis, and ischemia, necessitating careful insertion technique and vigilant monitoring. This review explores arterial lines' indications, techniques, complications, and clinical applications, emphasizing best practices to optimize patient safety and hemodynamic assessment. As with all invasive procedures, arterial catheterization may present complications, and personnel must be ready to intervene promptly to prevent unnecessary harm to the patient.
