A plastic catheter mount.
Among the disadvantages of catheter mounts in common use is that, as generally manufactured, they have sharp interior angles militating against laminar flow. The diagram illustrates the longitudinal section of a plastic variant in which the narrowing has been chamfered off. It has been found satisfactory in practice, and seems to be standing up robustly to use. It has the additional advantage o...
متن کاملManaging blocked foley catheter balloons when removing posterior nasal packs in epistaxis patients.
INTRODUCTION In emergency otolaryngology, Foley catheters are often used to stop posterior epistaxis. Foley catheter balloons are prone to blockage, and this has been described in the literature since they were first introduced. There are numerous causes of a none-deflating Foley catheter balloon. These include blockage of the internal lumen with salt crystals, failure in the valve, or most com...
متن کاملConquering Mount Fuji: Resolution of Tension Pneumocephalus with a Foley Urinary Catheter
Tension pneumocephalus is the presence of air or gas in the cranium that is under pressure. It occurs due to disruption of the skull, including trauma to the head or face, after neurosurgical procedures and occasionally, spontaneously (Schirmer et al., 2010). Patients typically present with headache but can also have neurological deficits such as decreased mental status, numbness, and weakness ...
متن کاملMucopolysaccharidosis I cats mount a cytotoxic T lymphocyte response after neonatal gene therapy that can be blocked with CTLA4-Ig.
Although gene therapy has reduced manifestations of genetic diseases, immune responses can abrogate the effect. One approach to inducing tolerance is to perform gene transfer in newborns when the immune system is immature. We demonstrate here that the dose of retroviral vector (RV) is important in mice, as mucopolysaccharidosis I (MPS I) mice that received neonatal intravenous gene therapy with...
متن کاملBlocked Clause Decomposition
We demonstrate that it is fairly easy to decompose any propositional formula into two subsets such that both can be solved by blocked clause elimination. Such a blocked clause decomposition is useful to cheaply detect backbone variables and equivalent literals. Blocked clause decompositions are especially useful when they are unbalanced, i.e., one subset is much larger in size than the other on...
