Study Notes

Cumulative damage to blood vessels due to multiple organ systems aging
Chronic conditions affecting arteries, including diabetes, hypertension, chronic kidney disease, hepatitis C, inflammatory bowel disease, cancer, and hypothyroidism
Skin changes such as collagen depletion, hormone reduction, and dehydration
Lifestyle factors affecting circulation: poor nutrition, chronic stress, alcohol use, smoking, environmental exposures (like cigarette smoke).

Laboratory Values-Device Placement

White Blood Cells (WBC): Normal range 4,500-10,000/mcL; higher counts (leukocytosis) usually indicate an infection, which may need treatment. (Trauma, hemorrhage, coronary occlusion, malignancy, pregnancy, and VAD device use in active infections can also cause leukocytosis.)
Other considerations: Infection in patients with vascular access devices can lead to systemic infections; consult with appropriate specialists to guide device type and appropriate insertion timing. Patients with elevated WBC or trending upwards may indicate infection not responding to antibiotics.

Kidney Function

Glomerular Filtration Rate (GFR): Normal range is 90-120 mL/min/1.73 m². Used to evaluate kidney function; estimates the blood filtered through glomeruli each minute..
Creatinine: Normal range 0.7-1.3 mg/dL (males) and 0.4-1.1 mg/dL (females). Indicates kidney function level and identifies kidney disease risk. Those with elevated creatinine or low GFR need a tailored vascular access plan. Low GFR or elevated creatinine in patients with CKD may necessitate prompt vascular access evaluation.

Coagulation Studies

Platelets: Normal range 150,000-450,000 per microliter. Placement of vascular access devices in thrombocytopenic patients should be carefully guided. Consideration given to insertion sites allowing for optimal compressibility. PICC lines may be more appropriate for patients with hypercoagulability.
International Normalized Ratio (INR): 1.0-1.2, 2.1-3.0 in treatment with anticoagulant therapy. Patients taking vitamin K antagonists need INR monitoring for appropriate dosage adjustment and risk assessment. INR is calculated from prothrombin time (PT). Be aware of possible heparin contamination from the vascular access device.
