Early experience with a newly developed electrospun polycarbonate-urethane vascular graft for hemodialysis access.
PURPOSE In this pilot study, we tested a newly developed electrospun multilayered, self-sealing graft, AVflo™, specifically designed for early hemodialysis access. METHODS Ten eligible consenting patients had a polycarbonate-urethane graft (AVflo™) implanted and were followed up prospectively for at least six months. Performance measures included graft patency, complications and time to fir...
متن کاملPatient reactions and granulocyte degranulation during hemodialysis with cuprophane and polycarbonate membranes. A double-blind study.
During dialysis with cuprophane or polycarbonate filters, a fall in neutrophil and eosinophil cell counts is observed. Total complement remains unchanged, but C3a increases indicating complement activation. Release of granular granulocyte proteins is observed indicating granulocyte activation. Patient reactions or biochemical findings indicate no significant difference when polycarbonate or cup...
متن کاملAcid-fast microscopy on polycarbonate membrane filter sputum sediments.
Polycarbonate membrane filters were used to concentrate 916 sputum specimens for detecting acid-fast bacilli by microscopic examination. These results were compared with those of smears prepared from centrifugates and direct smears of the same specimens. Culture isolation, the control procedure, demonstrated the presence of acid-fast bacilli in 76 specimens. The number of positive specimens det...
متن کاملThe Physical Effects Of Volatile Anesthetics On Polycarbonate Membrane Oxygenators
The spillage of enflurane on the outside of a membrane oxygenator during cardiopulmonary bypass resulted in a leak at the venous outlet, with nearly fatal outcome. We studied the effect of three different volatile anesthetics on the polycarbonate parts of unused and used COBE CMS membrane oxygenators with 30-HRV open filtered reservoir. The polycarbonate parts were submitted to a series of test...
متن کاملComparative poliovirus permeability of silver, polycarbonate, and cellulose membrane filters.
Three types of filters, silver, polycarbonate, and cellulose, were evaluated for permeability toward poliovirus suspended in water, salt-containing, and proteinaceous solvents. The ability of virus to pass through cellulose filters depended on the suspending medium; virus did not pass through cellulose filters in either water or salt solution, whereas the use of protein solutions increased filt...
