1/2. ventricular fibrillation during general anaesthesia in a seven-year-old patient with mitral valve prolapse.A case report is presented of a seven-year-old boy who developed ventricular fibrillation during general anaesthesia with atracurium, O2, N2O and halothane, following tracheal intubation for hypospadias revision. He spontaneously defibrillated and the surgery was cancelled. echocardiography done two days later was normal. The patient returned two weeks later for the same procedure. He developed nodal tachycardia, and premature ventricular contractions, which responded to lidocaine. A second echocardiographic examination done postoperatively while the child was crying showed mitral valve prolapse.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/2. ventricular fibrillation in a patient with unsuspected mitral valve prolapse and a prolonged Q-T interval.mitral valve prolapse is a common cardiac abnormality associated with arrhythmias and sudden death. In most instances it can be diagnosed on the basis of physical findings. Those patients who are symptomatic or who display electrocardiographic abnormalities appear to be most susceptible to arrhythmias and, therefore, may be at increased risk for anaesthesia. Because the syndrome is relatively common and may present a very innocent clinical picture, anaesthetists should be aware of this condition and the problems it may present. A case of mitral valve prolapse syndrome associated with ventricular fibrillation on induction of anaesthesia is reported. The symptoms and pathophysiology of the disorder are reviewed and the potential problems and the anaesthetic management are discussed.- - - - - - - - - - ranking = 0.4keywords = anaesthesia (Clic here for more details about this article) |
