Bedside Ultrasound by Anesthesiologists for Screening Deep Venous Thrombosis

A Pilot Study of Bedside Ultrasound by Anesthesiologists for Screening Deep Venous Thrombosis in High Risk Patients Following Hip Fracture and Major Joint Arthroplasty

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 800 (actual)
• Sponsor: University Health Network, Toronto · Academic / Other
• Sex: All
• Age: 18 Years – 85 Years
• Healthy volunteers: Not accepted

Summary

The study is designed as a prospective comparative study. All patients will receive prophylactic anticoagulation according to routine hospital protocol after surgery. A bedside ultrasound examination will be performed by a trained anesthesiologist prior to the surgery and then daily beginning on postoperative day 2 until patient discharge.

Detailed description

Recent studies conducted at the emergency department evaluated the usefulness of an abbreviated bedside compression ultrasound test for diagnosis of Deep Venous Thrombosis (DVT) in the proximal region. This abbreviated ultrasound test conducted in the groin and popliteal regions to assess the compressibility of the femoral and popliteal veins required as little as 3.5 min to complete 15 and can be easily mastered by residents with minimum training. These studies showed a promising sensitivity ranging from 70% to 100% and a specificity ranging from 75.9% to 99.6%. Anesthesiologists are now well-trained in performing ultrasound scans as they perform ultrasound-guided peripheral nerve blocks routinely. Scanning for significant proximal DVT could potentially be anesthesiologists' extended role as they follow up patients who underwent orthopedic surgeries for postoperative pain control as part of the acute pain service.
