Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Tourniquet for ankle fracture surgery?

The research indicates that using a tourniquet during ankle fracture surgery does not significantly affect hospital stay or operation time, but it may increase postoperative swelling and pain. Therefore, the effectiveness of tourniquet use in improving surgical outcomes for ankle fractures is not clearly supported by the available data. ^{1 2 3 4 5}

Is tourniquet use generally safe for humans?

Tourniquet use during surgery is generally considered safe, but it can increase postoperative swelling and pain, and there are potential risks like vascular compromise (blood flow issues). Proper assessment and understanding of patient history can help prevent unwanted outcomes. ^{1 3 6 7 8}

How does tourniquet use differ from other treatments for ankle fracture surgery?

Using a tourniquet during ankle fracture surgery is unique because it provides a bloodless field for the surgeon, which can make the operation easier. However, it may lead to increased swelling and pain after surgery compared to not using a tourniquet. ^{1 2 3 4 7}

What is the purpose of this trial?

This study aims to 1) characterize skeletal muscle pH during/after tourniquet use and 2) investigate any relationship between intraoperative tourniquet use and postoperative functional measures and patient-reported outcomes.

Eligibility Criteria

Adults aged 18 to 89 who are having surgery for an ankle fracture at OHSU can join this trial. It's not for those with other major bone or internal injuries, including on the same limb, or people with sepsis.

Exclusion Criteria

I have had serious injuries to my bones or internal organs.

I have had sepsis before.

Treatment Details

Interventions

• Tourniquet

Trial Overview The study is looking at how using a tourniquet during ankle surgery affects muscle pH levels and if there's any link between its use and how well patients recover functionally and what they report about their outcomes after surgery.

Participant Groups

Group I: Tourniquet Active Control 1 Intervention

This arm will have a tourniquet placed around the thigh inflated to 250mmHg for the duration of surgery (until splint placed) or 2 hours, whichever is shorter, during ankle fracture surgery.

Group II: No Tourniquet Active Control 1 Intervention

This arm will have a tourniquet placed around the thigh but NOT inflated for the duration of ankle fracture surgery.

Findings from Research

Tourniquet use during extremity surgery is generally safe, but requires careful assessment of patient history and understanding of risks to prevent complications.

Knowledge of the physiological effects of tourniquets, including their impact on skin, vascular health, and postoperative pain, is essential for improving surgical outcomes and ensuring safe perioperative care.
