Case Reports[Cerebral air embolism complicating talc pleurodesis: case report].
Cerebral air embolism is a severe complication which can occur during many invasive medical procedures. Its prognosis depends on early diagnosis and hyperbaric oxygen therapy. We report a case of cerebral air embolism which occurred during a talc pleurodesis within a chest tube, in chest postoperative period. After early and appropriate treatment, we observed a significant functional recovery.

Case Reports[Pulmonary hypertension and femoral neck fracture: interest of continuous spinal anaesthesia].
Anaesthetic management of patients with pulmonary hypertension is challenging and alternatives to general anaesthesia are encouraged. We report anaesthetic management of two patients with pulmonary hypertension admitted for femoral neck fracture. In order to reduce the risk of right-sided heart failure and systemic hypotension, it was decided to operate the patients under continuous spinal anaesthesia. ⋯ Quality and extension of the block was correct and allowed surgery. No postoperative complication was observed. These cases suggest that continuous spinal anaesthesia may be considered for the management of patients with pulmonary hypertension undergoing femoral neck fracture surgery.

Case Reports[Continuous haemodialysis with citrate anticoagulation in patients with liver failure: three cases].
Regional citrate anticoagulation for continuous renal replacement therapy provides an efficient alternative to heparin as it reduces the likelihood of haemorrhage in critically ill patients with bleeding risk or coagulopathy and increases the haemofilter survival time. Liver failure is a classic contraindication of regional citrate anticoagulation since it carries the risk of citrate accumulation and its metabolic complications, although it could be attractive for this population of patients with high bleeding risk. ⋯ For these patients, close monitoring of the total-to-ionized calcium ratio, pH and anion gap is particularly essential to control the safety of citrate infusion. Increasing effluent flow rate eliminates more calcium-bound citrate and therefore limits citrate accumulation and its consequences.

Case Reports[Major haemodynamic incident during continuous norepinephrine infusion: Beware of the infusion line. An avoidable postoperative hypertensive peak?].
The restoration of patients' mean arterial pressure after ineffective fluid resuscitation is obtained by vasopressive treatment such as norepinephrine. However, no guidelines exist concerning a norepinephrine infusion method: whether it be the norepinephrine concentration in the syringe, single or double pump administration via a carrier such as an isotonic saline solution, or use of minimized dead-volume extension sets. We present the case of a female patient requiring norepinephrine treatment, who quickly suffers a major haemodynamic incident (a sudden rise in systolic blood pressure above 220 mmHg associated with tachycardia up to 189 b/min). The main causes of this incident are discussed and infusion parameters considered with a view to developing an optimal infusion method for a drug with a specific therapeutic index.

Case Reports[Coronary artery dissection complicated by myocardial infarction in a head trauma patient].
Acute myocardial infarction, following coronary artery dissection, is a rare, but potentially fatal, syndrome after blunt chest trauma. The treatment is more complicated when intracerebral lesions are present, because of the need of anticoagulation. We report the case of a 37-year-old male patient, suffering from a polytraumatism with intracranial petechial haemorrhages who have a left coronary artery dissection with acute myocardial infarction.
