High frequency jet ventilation (HFJV) is an alternative ventilatory mode during anaesthesia for laryngeal microsurgery. This procedure ensures good visualization of the operating field but is not without risk. Thus, its use in paediatric patients requires sound knowledge of respiratory physiology of children and infants. ⋯ The air-oxygen mixture must be adjusted to provide the lowest FIO2 possible (< or = 30%) when using the CO2 laser. The main indications for the use of HFJV in paediatric laryngeal microsurgery are laryngomalcia, laryngeal papillomatosis and subglottic haemangioma. HFJV is a reliable and useful technique in airway paediatric surgery providing the operator has good knowledge of the physiological particularities in children.

Case Reports[Vasodilatory septic shock refractory to catecholamines: is there a role for terlipressin?].
We report two patients in vasodilatory septic shock refractory to catecholamines in which a continuous infusion of terlipressin was associated with a dramatic increase in systemic arterial blood pressure and short-term survival. Low doses of terlipressin were sufficient in both cases (0.01-0.0 mg h(-1)) to restore blood pressure by increase of systemic vascular resistances. The haemodynamic response was immediate, long-acting, dose-dependent and reversible in a few hours when the drug administration was stopped. ⋯ Terlipressin simultaneously induced vasoconstriction within the cutaneous vascular territory, leading to local skin necrosis. The splanchnic vascular territory seemed to be constricted in the same way. Further studies are needed to better understand and precise the role of terlipressin in the treatment of vasodilatory septic shock refractory to catecholamines.

Case Reports[Left ventricular thrombus and myocarditis induced by paraphenylenediamine poisoning].
We showed that the paraphenylenediamine (PPD) poisoning caused myocarditis but there is no data on the echocardiographic features. We report a case of myocarditis induced by PPD poisoning with echographic data. After ingestion of 5 g of PPD, a 18-year-old woman was admitted to the hospital with asphyxia and rhabdomyolysis. ⋯ A follow-up echocardiogram performed on the 15th day showed normalization of ventricular function and disappearance of the thrombus. No embolic event was noted. Echocardiography is indicated in the myocarditis induced by PPD poisoning to prove the ventricular function as well as the presence of a thrombus.

Case Reports[Lepirudin during cardiopulmonary bypass in a patient with heparin-induced thrombocytopenia].
Lepirudin is an alternative anticoagulant therapy in heparin-induced thrombocytopenia (HIT) during cardiopulmonary bypass (CPB). We report a case of a female patient with HIT referred for aortocoronary bypass graft despite persistence of antibodies to platelet factor 4-heparin complexes. Anticoagulation management is described. ⋯ Total lepirudin administration was 44 mg. No haemorrhagic or thrombotic events were observed during surgical procedure and postoperative course. Despite lepirudin administration is not yet clearly precise for CPB procedure, its use seems adapted and safe in subjects without renal insufficiency but requiring precise coordination for anaesthesiological, surgical and biological teams.
