[Preterm labour after adenosine treatment for paroxysmal supraventricular tachycardia during pregnancy, a case report].
Paroxysmal supraventricular tachycardia is the most frequent arrhythmia among young pregnant women. In case of failure of vagal manoeuvres, their management is preferentially intravenous infusion of adenosine. ⋯ Adenosine administration was immediately followed by a preterm labour managed by calcium channels blockers tocolysis. Even if causal relationship remains uncertain, this observation is consistent with physiopathological data and should catch physician's attention when initiating this treatment.

The ovarian hyperstimulation syndrome (OHSS) is a complication of controlled ovarian hyperstimulation (COH) protocols performed in women undergoing assisted reproductive technologies. This syndrome is characterized by multiple intra-ovarian corpus luteum and constitution of a third space that can lead to a life-threatening situation. Although the pathophysiology remains unclear, vascular endothelial growth factor (VEGF) and other cytokines, secreted under the influence of exogenous gonadotrophins administered for COH, are involved in increasing capillary permeability. ⋯ Mortality rate, though not accurately quantified, is significant (1/45 000 to 1/500 000) and mostly due to thromboembolic complications. The only effective treatment is prevention, by adapting ovarian stimulation protocols to OHSS risk factors. There are no specific treatments and therapy is mainly symptomatic until the condition resolves spontaneously.

Comparative Study Clinical Trial[High-flow nasal oxygen for severe hypoxemia after cardiac surgery].
High-flow nasal oxygen (Optiflow™) is validated in paediatric intensive care but not in adults' patients for severe hypoxemia. The aim of this study was to evaluate this oxygen system delivery in adults' patients for postoperative hypoxemia after cardiac surgery. ⋯ These results give good arguments for an improvement in gas exchange and better tolerance of high-flow nasal oxygen (Optiflow™) versus classical high-flow oxygen face mask in postoperative cardiac patients. These results must be confirmed by a randomised study with a larger population.
