Dopamine has been widely used in the past for improving renal function but was abandoned due to lack of evidence and various potential serious side effects. In the new Heart Failure Guidelines 2013 of the AHA.pdf there is an interesting note in the section hospitalized patients with heart failure: low-dose dopamine infusion may be considered in addition to loop diuretic therapy to improve diuresis and better improve renal function. The level of evidence is IIb/B which means that efficacy is less well established and that there is greater conflicting evidence from trials. Indeed, when looking at the cited articles more questions than answer remain… but see yourself.
50% of all pregnant women suffer of sometimes severe nausea and vomitus, especially at the beginning of their pregnancy. In a cohort of 600’000 pregnancies, in which 25% of all women took Ondansetron, no increased risk for fetal abnormalities or miscarriages was shown. A good news for all pregnant, though the risk of QT prolongation has to be considered.
In this randomized, non-inferiority multi-center trial in 5 swiss teaching hospitals, 314 patients that presented to casualty with exacerbation of COPD were enrolled. They were treated with oral prednisolon for either 5 or 14 days.
Results showed that a 5-day treatment was non-inferior to a 14-day treatment with regard to re-exacerbation within 6 months but significantly reduced glucocorticoid exposure. As so often: Less is more!
