Summary
The Vascular Access (VA) scale is a practical tool for assessing peripheral venous systems. It improves patient quality of life by increasing successful venipuncture, reducing extravasation risk, and lowering costs.
Area of Science:
- Vascular Access
- Oncology Nursing
- Medical Device Evaluation
Background:
- Peripheral venous system assessment is crucial for effective intravenous therapy.
- Current methods may lack standardization, impacting patient outcomes.
- The Vascular Access (VA) scale offers a structured approach to evaluating venous integrity.
Purpose of the Study:
- To introduce and validate the VIA scale as a dynamic tool for peripheral venous system assessment.
- To evaluate the correlation between the VIA scale and objective measurements of vein diameter.
- To assess the clinical utility of the VIA scale in improving vascular access outcomes.
Main Methods:
- Prospective, observational, single-center study with two phases.
- Phase 1: Longitudinal assessment of venous system changes during chemotherapy (n=16).
- Phase 2: Correlation of VIA scale with high-resolution ultrasound vein diameter measurements in oncology patients (n=52) and controls (n=56).
Main Results:
- Excellent inter-rater agreement was observed for the VIA scale.
- Vein diameter measurements showed a decrease directly related to VIA scale assessments.
- The VIA scale effectively classifies the peripheral venous system for vascular access.
Conclusions:
- The VIA scale is a simple, practical, and reliable method for classifying the peripheral venous system.
- Clinical application of the VIA scale enhances patient quality of life by improving venipuncture success rates.
- The VIA scale reduces extravasation risk and material costs, offering an economical and safe venous assessment tool.

01:27Assessment of the Cardiovascular System III: Palpation
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:29Assessment of the Cardiovascular System II: Inspection
Inspection is the initial step in assessing the cardiovascular system. It involves a detailed visual examination that provides crucial information about a patient's circulatory and cardiac health. This systematic process, conducted from head to toe, helps identify signs of cardiovascular conditions by observing physical appearance, skin and mucous membranes, jugular and carotid pulsations, chest symmetry, and the condition of the extremities.

01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
01:26Varicose Veins I: Introduction
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
