|DVT||Procedure: Ultrasound assessment of DVT||Not Applicable|
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.

Ultrasound assessment of DVT
DVT ultrasound vs Clinical assessment in high-risk patients following hip fracture and major arthroplasty before the patients become symptomatic.
Procedure: Ultrasound assessment of DVT
Using Ultrasound in assessing DVT in high-risk patients following hip fracture and major arthroplasty before the patients become symptomatic.
- The accuracy of a positive bedside ultrasound scan [ Time Frame: post operative day 2 ]To evaluate the accuracy of a positive bedside ultrasound scan as compared to clinical assessment for the detection of an occluding DVT.
- The degree of technical difficulty [ Time Frame: from start to of bedside compression test up to 1 hour ]The degree of technical difficulty in visualizing relevant veins and in determining whether a clot is present. That is, the incidence of uninterpreted test data in patients with a swollen thigh/leg after major hip or knee surgery. The degree of technical difficulty will be recorded especially in patients with a high body mass index (BMI).
