Course Overview:
Preserving and replanting autologous tissue may enhance long-term patient outcomes. Cranial bone flaps or parathyroid glands may be stored when clinical factors such as infection, swelling, or abnormal hormone levels prevent immediate reimplantation during the procedure. Autologous tissue may be preferred over allografts or synthetic implants in certain situations—adhering to evidence-based guidance for autologous tissue management is essential.
Periop 303: Autologous Tissue Management provides scenario-based activities with 20 questions. Learners will review evidence-based procedures for autologous tissue management according to AORN Guidelines. Each scenario includes tips and reflection on practice to promote mastery. The goal is to assess a learner’s ability to apply knowledge in practical situations.
Course Outcomes:
90% of learners will recall the responsibilities for autologous tissue management in the perioperative setting, as evidenced by achieving a score of at least 80% on the test questions.
Course Objectives:
At the completion of this course, learners will be able to:
- Describe the recommendations for autologous cranial bone flap management for delayed cranioplasty.
- Explain the recommendations for cryopreserving and autotransplanting parathyroid tissue.
- Identify the important safety measures to take while handling autologous tissue.
- Describe autologous tissue packaging and labeling recommendations.
