A Novel Non-invasive Method for the Detection of Elevated Intra-compartmental Pressures of the Leg
Published on: May 31, 2019
Summary
A new, wider pneumatic tourniquet effectively occludes lower limb blood flow at lower pressures than standard tourniquets. This may reduce tourniquet-related complications during surgery.
Area of Science:
- Vascular Surgery
- Medical Devices
- Anesthesiology
Background:
- Pneumatic tourniquets are used to occlude blood flow in limbs during surgery.
- Conventional tourniquets require higher inflation pressures, potentially increasing complication risks.
- A novel, wider pneumatic tourniquet has been introduced.
Purpose of the Study:
- To evaluate the efficacy of a wide pneumatic tourniquet in occluding lower limb blood flow.
- To determine safe and effective inflation pressures for the wide tourniquet.
- To assess the potential for reduced complications with the new device.
Main Methods:
- Prospective study involving volunteers.
- Recording of intraoperative blood pressure fluctuations.
- Comparison of blood flow occlusion with wide versus conventional tourniquets.
Main Results:
- The wide tourniquet achieved blood flow occlusion at lower inflation pressures compared to the conventional tourniquet.
- Effective occlusion was achieved with the wide tourniquet at pressures no more than 125 mm Hg above systolic pressure.
- Lower inflation pressures were theoretically linked to reduced tourniquet-related complications.
Conclusions:
- The wide pneumatic tourniquet reliably occludes lower limb blood flow at reduced inflation pressures.
- This wider tourniquet offers a potential advantage in minimizing tourniquet-induced complications.
- Further clinical evaluation is warranted to confirm reduced complication rates.

01:11Pulse Assessment Sites
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:15Veins of Lower Limbs
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...

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...
