Severe and Transient Hypoxemia During Selective Intra-arterial Chemotherapy for Retinoblastoma in Children: Evaluation of the Right-sided Heart Function.
Severe and Transient Hypoxemia During Selective Intra-arterial Chemotherapy for Retinoblastoma in Children: Evaluation of the Right-sided Heart Function.
Children having selective ophthalmic artery chemotherapy for retinoblastoma under general
 anaesthesia may experience troubles during the procedure. The troubles are transient, may be
 severe and include hypoxemia, hypotension and bradycardia. All children having such trouble
 always fully recovered without any sequelae or prolonged length of stay. The investigators
 suspect that these phenomenons are caused by transient pulmonary hypertension.The objective
 is to see whether transient pulmonary hypertension and right-sided heart failure is present
 during theses phenomenon by trans-thoracic echocardiography.
