Final answer:
The KDOQI rules of 6s provide guidelines for evaluating the maturation of arteriovenous fistulas (AVF). Four evaluations based on these rules include the six-week assessment, six-month evaluation, six to twelve-month examination, and six-year assessment.
Step-by-step explanation:
One method of evaluating the maturation of arteriovenous fistulas (AVF) is through the KDOQI rules of 6s. Here are four AVF evaluations based on those rules:
- Six-week assessment: This evaluation checks for any signs of infection or inflammation at the site of AVF creation, as well as the development of any complications.
- Six-month evaluation: This assessment involves monitoring the blood flow rate and assessing the functionality of the AVF. It also looks for any stenosis or signs of thrombosis.
- Six to twelve-month examination: During this evaluation, the patency of the AVF is checked using various methods such as ultrasound, angiography, or venography to ensure its continued functionality.
- Six-year assessment: This long-term evaluation focuses on assessing the durability of the AVF, checking for any signs of stenosis or thrombosis that may require intervention.
