Intermittent pneumatic compression is a therapeutic technique used in medical devices that include an air pump and inflatable auxiliary sleeves, gloves or boots in a system designed to improve venous circulation in the limbs of patients who suffer edema or the risk of deep vein thrombosis (DVT) or pulmonary embolism (PE). In use, an inflatable jacket (sleeve, glove or boot) encloses the limb requiring treatment, and pressure lines are connected between the jacket and the air pump. When activated, the pump fills the air chambers of the jacket in order to pressurize the tissues in the limb, thereby forcing fluids, such as blood and lymph, out of the pressurized area. A short time later, the pressure is reduced, allowing increased blood flow back into the limb. The primary functional aim of the device "is to squeeze blood from the underlying deep veins, which, assuming that the valves are competent, will be displaced proximally." When the inflatable sleeves deflate, the veins will replenish with ...
Deep Vein Thrombosis (DVT) is a life threatening condition and a serious concern among hospitalized patients, with death occurring in approximately 6% of cases. It involves the formation of a clot where stagnant blood flow occurs, predominantly in the deep veins of the legs. Three mechanisms underlie DVT, venous stasis (slowing or stopping of the blood), hypercoagulability (increased clotting) and damage to blood vessel endothelium (damage to blood vessel wall), collectively known as Virchows triad.. Intermittent Pneumatic Compression (IPC) involves the use of an inflatable cuff placed around the limb. This cuff inflates and deflates intermittently in order to squeeze blood from the underlying veins. Neuromuscular Electrical Stimulation (NMES) leads to a contraction of muscles by delivering a series of controlled electrical pulses via skin surface electrodes placed over the motor points of the targeted muscle. ...

Though home treatment is an option in some cases, most patients suffering from deep vein thrombosis will require hospitalization, as most will have additional risk factors that will require more monitoring than home care can provide. Deep vein thrombosis is typically treated by breaking down the clot with thrombolytic agents. Patients are then given anticoagulants to prevent the formation of new clots and pulmonary embolism. For patients that cannot undergo anticoagulant treatment, an inferior vena cava filter can also be used to reduce the occurrence of pulmonary embolism. However, this treatment is viewed only as a temporary measure to prevent the more life threatening pulmonary embolism. For medical and surgical inpatients, prevention is key and most hospitals will use a combination of anticoagulants, thromboembolic deterrent stockings, and intermittent pneumatic compression devices to prevent deep vein thrombosis from occurring. For travelers, as well as those patients susceptible to deep ...

Because of the bodys normal response to surgery and the reduction in activity that usually follows surgery, blood clot, or thrombus, formation can be a common complication. A thrombus is a blood clot that blocks a blood vessel and reduces blood flow. A thrombus can also dislodge and travel to other parts of the body, such as the heart, lungs, or brain, causing serious health problems.. Preventive or prophylactic steps can be taken to decrease the chance of developing a blood clot (thrombosis). The Joint Commission recommends that a venous thromboembolism (VTE) risk assessment be performed within 24 hours of admission to the hospital or intensive care unit. Treatment options should be evaluated for patients who are at high risk for a thrombus or VTE.. Effective venous thromboembolism prevention options include blood thinning medications, early mobilization and physical therapy, range-of-motion exercises, elastic stockings, and intermittent pneumatic compression devices (The Journal of Bone and ...
Antithrombotic prophylaxis in critically ill patients frequently fails. Venous thromboembolism is associated with adverse clinical outcomes, including a prolonged intensive care unit stay and death. A potential mechanism by which critically ill patients may be predisposed to antithrombotic failure is the inability to achieve prophylactic anticoagulant drug levels as a result of impaired absorption. For example, previous studies have shown that patients on inotropes have reduced serum levels of low molecular weight heparin, presumably on the basis of reduced absorption from the subcutaneous injection site. In the previous issue of the journal, Rommers and colleagues examined whether subcutaneous edema reduces absorption of a low molecular weight heparin; although small, and thus underpowered, the authors failed to find any relationship between the level of low molecular weight heparin and the presence of edema. These findings provide reassurance that subcutaneously administered medications may be used
Trauma patients are at a high risk of developing blood clots in the legs (deep vein thrombosis - DVT), which can travel to the lungs and cause serious health consequences. Often, these patients cannot receive blood-thinning medication to prevent these blood clots because of the risk of bleeding; in this case, they are usually given intermittent pneumatic compression devices (IPCs) to prevent blood clots. IPCs are inflatable sleeves that fit over the legs and periodically inflate and deflate, helping to pump blood out of the legs and thus reduce the risk of blood clot formation. Several studies suggest that IPCs are working properly on the patient only 60-70% of the time. Some patients also find them uncomfortable. A new device (geko) that works by stimulating the leg muscles and increasing blood flow in the legs has recently been developed. To compare the geko with IPCs, this study will randomly assign trauma patients who cannot receive blood thinners for blood clot prevention to either IPCs or ...

Ulceration of the lower limb is a chronic, debilitating condition affecting an increasing percentage of the adult and elderly populations. Conservative treatment options are limited, and generally result in surgery or amputation. The purpose of this research was to investigate the feasibility of using intermittent pneumatic compression for the treatment and management of chronic non-healing leg ulcers. The aim was to develop a system capable of improving the healing of leg ulcers of varying causes through improving distal blood flow whilst also being comfortable and easy to use, to encourage patient compliance. Using Doppler ultrasound, it was demonstrated that intermittent pneumatic compression was capable of producing a distal blood flow response in the limb of a healthy volunteer. Further investigations examined the effect on this distal response of altering the cuff design, pressure and cycle duration in order to determine the optimal compression regime for enhancing the distal circulation ...

Background: Conventional hemodialysis (HD) is associated with dialysis-induced hypotension (DIH) and ineffective phosphate removal. As the main source of extracellular fluid removed during HD are the legs, we sought to reduce DIH and increase phosphate removal by using cycling and pneumatic compression, which would potentially provide higher venous return, preserving central blood flow and also offering more phosphate to the dialyzer. Methods: We evaluated 21 patients in a randomized crossover fashion in which each patient underwent 3 different HD: control; cycling exercise during the first 60 min; and pneumatic compression during the first 60 min. Data obtained included bioelectrical impedance, hourly blood pressure measurement, biochemical parameters, and direct quantification of phosphate through the dialysate. DIH was defined as a drop in mean arterial pressure (MAP) ,= 20 mm Hg. Results: There was no difference in the ultrafiltration rate (p = 0.628), delta weight (p = 0.415), delta of ...

Venous thromboembolism (VTE) remains a significant complication following knee and hip arthroplasty. National and international guidelines recommend pharmacological and mechanical thromboprophylaxis following surgery, unless contraindicated, to reduce the risk of VTE. This study aimed to explore the safety and efficacy profile of an adapted thromboprophylaxis regimen consisting of sequential enoxaparin and rivaroxaban for thromboprophylaxis following knee or hip arthroplasty at a London teaching hospital. A total of 265 patients who received sequential enoxaparin and rivaroxaban and mechanical thromboprophylaxis following knee and hip arthroplasty were included in the study. Efficacy outcomes assessed for 90 days post-operatively included: pulmonary embolism, deep-vein thrombosis, other VTE, myocardial infarction, stroke and death secondary to thrombosis. Safety outcomes were assessed during and for two days after thromboprophylaxis course duration and consisted of major bleeding episodes, clinically
An institutional review board-approved retrospective review of outcomes in patients undergoing spine surgery 2 years before protocol implementation (representing the preprotocol group) and of outcomes in patients treated 2 years thereafter (the postprotocol group) was conducted. Inclusion criteria were that patients were 18 years or older and had been admitted for 1 or more days. Before 2008 (preprotocol), VTE prophylaxis was variable and provider dependent without any uniform protocol. Since 2008 (postprotocol), a new VTE-prophylaxis protocol was administered, starting either preoperatively or on the same day of surgery and continuing throughout hospitalization. The new protocol consisted of 5000 U heparin administered subcutaneously 3 times daily, except in patients older than 75 years or weighing less than 50 kg, who received this dose twice daily. All patients also received sequential compression device. The incidence of VTE in the 2 protocol phases was identified by codes of the ...

If you require surgery, talk with your health care provider about the plan to prevent DVT. Depending on the surgery, your doctor may prescribe a blood thinner (anticoagulant).. If you are hospitalized for an extended period of time, or if a surgery requires hospital admission, your risk for DVT increases. Your health care provider may prescribe an anticoagulant the day of, or the day after, admission. Your doctor may also advise sequential compression devices. These are special sleeves wrapped around the legs or feet that inflate and deflate through air tubes connected to an electric pump. This action promotes better blood circulation and thus prevents DVT. Also, follow these tips: ...
