Case Reports[Epidural analgesia in a pregnant woman with essential thrombocythaemia].
Epidural analgesia is often considered as risk of epidural haematoma in patient with essential thrombocythaemia because of the platelet disorder. In this observation, uncomplicated epidural analgesia was performed in a pregnant woman with asymptomatic essential thrombocythaemia, because the absence of bleeding symptoms was associated with normal thrombo-elastography and time of occlusion by PFA-100 suggesting normal platelet function. PFA-100 is a biological test evaluating platelet function in whole blood, which is easy and quick to perform. This case study suggests that this test might be useful in evaluating platelet function in obstetrics but must be validated before recommending its extensive use.

Clinical Trial[Spectral analysis of the ECG R-R interval permits early detection of vagal responses to neurosurgical stimuli].
To assess the efficacy of ECG spectral analysis, compared with heart rate (HR) monitoring in the detection of vagal response to surgical stimuli. ⋯ The ECG spectral analysis is a non-invasive technique, which permits the detection of intra-operative vagal reactions earlier than conventional monitoring of HR.

Case Reports[Posterior reversible encephalopathy syndrome: about 2 cases related to the cyclosporine].
Following a pulmonary transplantation for cystic fibrosis, 2 patients exhibited a syndrome associating arterial hypertension, headache, visual trouble and generalized seizures. Cerebral magnetic resonance imaging revealed diffuse cortical and subcortical lesions predominantly in posterior regions. The exclusion of alternate diagnoses and the disappearance of the symptoms when the cyclosporine treatment was stopped confirmed the diagnosis of cyclosporine-related reversible posterior encephalopathy syndrome (PRES). Immediate appropriate management resulted in symptom disappearance and regression of radiological images.

Case Reports[Orbital haemorrhage after medial canthus episclera (sub-Tenon's) anaesthesia].
Medial canthus episclera (sub-Tenon's) anaesthesia is a technique proposed as a suitable alternative to the more classical peribulbar block because of the greater reliability and more constancy in effectiveness. We report two cases of retrobulbar haematoma after sub-Tenon's anaesthesia, one with central retina artery compression needed anterior room punction. Sub-Tenon's anaesthesia, like peribulbar anaesthesia, can give also retrobulbar haemorrhage if the insertion of the needle is not limited to the anterior orbit.

Comparative Study[Assessment of 44 heat and moisture exchange filters. What to choose?].
If the use of heat and moisture exchange filter (HMEF) in anaesthesia is recommended by the French Society of Anaesthesia and Intensive Care (SFAR), the criteria's choice are not clearly defined. Many HMEF are proposed by manufacturers which technical characteristics are different. ⋯ Criteria's used by manufactures to evaluate there filters are not always precised or too restrictive. The technical tests, the international norms, the certificates of validation, the ergonomic qualities and the definition of our needs are the main elements of choice of a filter.
