Disease relevance of Plethysmography, Impedance

• We have compared technetium-99m (99mTc) red blood cell (RBC) venography to serial impedance plethysmography (IPG) in 110 consecutive patients with a first episode of clinically suspected deep vein thrombosis (DVT) [1].
• With the criteria for thromboembolism of abnormal impedance plethysmography and confirmatory clinical signs, protection seems to have been afforded by hydroxychloroquine sulfate [2].

High impact information on Plethysmography, Impedance

• Serial BTG measurements were made in urine (40 patients) and plasma (20 patients) from high-risk neurosurgical cases who were screened with 125I-fibrinogen leg scanning and impedance plethysmography [3].
• All patients underwent DVT surveillance with iodine 125-labeled fibrinogen leg scanning and impedance plethysmography [4].
• Assessment of the optimal atrio-ventricular delay in DDD paced patients by impedance plethysmography [5].
• DESIGN--A non-invasive technique, impedance plethysmography, was applied to the assessment of the effects of sublingual glyceryl trinitrate on the compliance of the forearm and digital arteries [6].
• Serial impedance plethysmography was performed in all patients; a 125I-radiolabelled fibrinogen uptake test was added to impedance plethysmography in a randomized subsample of 62 patients (MF 701, 28; UFH, 34) [7].

Chemical compound and disease context of Plethysmography, Impedance

• Each patient underwent examination for deep vein thrombosis with iodine-125 leg scanning, impedance plethysmography and contrast venography [8].
• Acute spinal cord injury patients were assigned alternately to a control and a heparin prophylaxis group to determine the effect of 5,000 micro sodium heparin subcutaneously every 12 hours on the incidence of venous thrombosis as detected by impedance plethysmography of the lower extremities [9].

Associations of Plethysmography, Impedance with chemical compounds

• The patients were anticoagulated with heparin and warfarin for at least three months; impedance plethysmography, Doppler, and duplex scans were repeated at scheduled intervals [10].
• The effect of As2 and Cinnarizin on cerebral circulation is studied on rabbits using the method of local cerebral rheography [11].
• We have found that after the naftidrofuryl treatment tcPO2 significantly increased from 38.5 +/- 0.8 mm Hg to 54.6 +/- 11.5 mm Hg, and the impedance plethysmography indexes, such as the height of the rheographic wave, the area of the rheographic wave and the rheographic index were also slightly increased [12].
• One hundred forty-one indium study patients also underwent Doppler ultrasonography/impedance plethysmography (Doppler/IPG) as a comparative non-invasive technique [13].
• Five patients exposed to vinyl chloride were studied by hand angiography and other non-invasive methods, including photoplethysmography, rheography, and thermography [14].

Gene context of Plethysmography, Impedance

• Impedance plethysmography in human limbs. Part 1. On electrodes and electrode geometry [15].
• Fourier analysis of impedance rheography for peripheral arterial occlusive disease [16].
• The results of this study indicate that impedance plethysmography can be used to measure segmental cardiovascular responses during LBNP and that females may be less tolerant to -60 mm Hg LBNP than males [17].
• Using venous occlusion impedance plethysmography, leg blood flow was measured in seventeen men undergoing transurethral prostatectomy under either amethocaine spinal anaesthesia (SAB) or nitrous oxide-halothane general anaesthesia (GA) [18].

Analytical, diagnostic and therapeutic context of Plethysmography, Impedance

• Changes in blood flow and blood redistribution were measured by impedance plethysmography in the pelvic and leg regions of six male and four female subjects during three 5-min exposures to -20, -40, and -60 mm Hg lower body negative pressure (LBNP) [17].
