Once versus twice daily injection of enoxaparin for thromboprophylaxis in bariatric surgery: effects on antifactor Xa activity and procoagulant microparticles. A randomized controlled study.

Background: The optimal scheme of thromboprophylaxis in bariatric surgery remains uncertain, because clinical practice is different between countries and randomized trials are lacking.

Objectives: The primary objective of this randomized multicenter study was to determine the optimal regimen of enoxaparin providing an antifactor Xa peak activity between .3 and .

Occurrence of and risk factors for electroencephalogram burst suppression during propofol-remifentanil anaesthesia.

Background: Suppression ratio (SR) derived from bispectral index (BIS) monitoring is correlated to EEG burst suppression. It may occur during deep anaesthesia, but also in the case of metabolic or haemodynamic brain injury. The goal of the study was to describe the occurrence of SR and to determine factors associated with SR during propofol-remifentanil general anaesthesia maintenance.

[Takotsubo syndrome: a young woman case].

After induction of anaesthesia for lumbar disc herniation surgery, an ASA-1, 39-year-old woman presented an acute heart failure. A persistent hypotension with tachycardia was observed after a brief hypertension peak during orotracheal intubation. After electrocardiogram, echocardiogram and biologic dosages, the diagnosis seems to be coronary ischemia.
