Summary
Implementing a protocol for retrievable inferior vena cava filters (RIVCF) significantly improved filter retrieval rates in trauma patients. This prospective monitoring protocol enhanced patient safety by increasing successful RIVCF removal.
Area of Science:
- Trauma Surgery
- Vascular Surgery
- Medical Device Technology
Background:
- Retrievable inferior vena cava filters (RIVCF) are increasingly used in trauma patients at high risk for venous thromboembolism.
- This study evaluates the impact of an institutional protocol on RIVCF retrieval rates at a Level I trauma center.
Purpose of the Study:
- To assess the effectiveness of an institutional protocol in improving the retrieval rates of retrievable inferior vena cava filters (RIVCF) in trauma patients.
- To compare RIVCF retrieval rates before and after the implementation of a prospective monitoring protocol.
Main Methods:
- A retrospective review of 94 trauma patients who received RIVCF before protocol implementation (Group I).
- A prospective follow-up of 61 trauma patients who received RIVCF after protocol implementation (Group II).
- Comparison of filter retrieval eligibility, attempt, and success rates between the two groups.
Main Results:
- Filter retrieval eligibility was met by 81% in Group I and 61% in Group II.
- Retrieval attempt rates significantly increased from 42% in Group I to 95% in Group II (P < .001).
- Successful retrieval rates rose from 37% in Group I to 84% in Group II (P < .001), with no complications.
Conclusions:
- An institutional protocol for prospective monitoring of RIVCF significantly enhances filter retrieval rates in trauma patients.
- The protocol effectively addresses barriers to retrieval, leading to higher successful removal rates and improved patient safety.

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
