Filter by:We wish to compare the effect of very clean water used for dialysis therapy (i.e ultrapure water) in comparison with the use of conventional water which are used in most dialysis units worldwide. To the best of our knowledge prospective data in that field is sparse.
Intranasal injection of epinephrine is used routinely during endoscopic sinus surgery (ESS) to reduce bleeding in the nasal mucosa and thereby improve visualization of the surgical field. However, systemic absorption of epinephrine via the nasal mucosa is often accompanied by cardiovascular side effects during the early postinjection period, putting in risk patients with cardiovascular morbidity. Evidence indicate that topical administration of epinephrine achieves similar hemostatic effects compared with injection of epinephrine, while avoiding systemic adverse effects. We wish to conduct a prospective controlled trial assessing the hemostatic and hemodynamic effects of intranasal injection compared to topical application of epinephrin during ESS, in order to evaluate whether the previous could be avoided due to its untoward effects. We hypothesize that topical administration of epinephrine provides a hemostatic effect not inferior to that of intranasal injection while minimizing hemodynamic instability during ESS.
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's disease.
