ABSTRACT
Double lumen tubes (DLT) are a cornerstone in thoracic anaesthesia to achieve onelung ventilation. Due to the shape and size of these devices, airway injuries might occur. The reported incidence of tracheobronchial ruptures caused by a DLT is very low (0.005% for single-lumen tubes and 0.05% for double-lumen intubations), but the outcome can be life-threatening (1, 2). In the past, treatment of tracheobronchial ruptures was performed surgically, nowadays conservative treatment can be considered (3, 4). Here, we report a case of tracheobronchial rupture during oesophageal surgery.

PURPOSE: In this literature review, we try to give anesthesiologists a better understanding about Junctional Ectopic Tachycardia (JET), a narrow complex tachycardia that frequently occurs during and after surgery for congenital heart disease. SOURCE: Information was found in the databases of Pubmed, Science Direct, Medline and the Cochrane Library, by using the mesh terms "Tachycardia, Ectopic Junctional", combined with "Diagnosis", "Etiology", "Physiopathology", "Complications" and "Therapy". The publication date of the articles ranged from 1990 to 2012. PRINCIPAL FINDINGS: Risk factors for the development JET are surgery near the AV node, a duration of cardiopulmonary bypass longer than 90 minutes, young age, the use of inotropic drugs and hypomagnesaemia. The diagnosis of Junctional Ectopic Tachycardia can be made on a 12-lead ECG, demonstrating a narrow-complex tachycardia with inverted P-waves and VA dissociation. Adenosine administration and an atrial electrocardiogram can help to confirm the diagnosis. If JET has a minimal impact on the hemodynamic status of the patient, risk factors should be avoided and the adrenergic tonus should be reduced. Hemodynamic unstable JET can be treated by amiodarone, hypothermia and pacing. Extracorporeal membrane oxygenation (ECMO) and radiofrequency or cryoablation are treatment options for life-threatening and resistant JET. CONCLUSION: JET is the most frequent arrhythmia during and after congenital cardiac surgery. The ECG is the only available method to diagnose JET, demonstrating inverted P-waves and VA-dissociation. Amiodarone seems to be the most effective treatment option, because it can restore sinus rhythm and reduces the JET rate.
