title: [Anesthetic management in two infants undergoing hemilaminectomy for giant mediastinal neuroblastoma].
abstract: We report the anesthetic management in two infants who were a three-month-old boy (case 1) and a two- month-old girl (case 2), undergoing hemilaminectomy for giant mediastinal neuroblastoma. Neuroblastoma invades into the intrathecal space in a rare occasion, resulting in paraplegia, which requires emergent operation to save the spinal cord. Mediastinal neuroblastoma also possesses significant respiratory and cardiovascular risks due to the close anatomic relationship with vital organs. In the present report, we show that preoperative computed tomography (CT) scan and/or echocardiography revealed tracheal deviation in case 1 and mass compression of the left atrium in case 2. Therefore, the patients with mediastinal masses should be carefully evaluated before subjecting them to anesthesia. Especially, there is a possibility that the masses which do not appear to compress the airway and cardiovascular systems develop the airway obstruction and cardiovascular collapse after induction of general anesthesia. In fact, before induction of general anesthesia in the case 2, trial of the prone positioning which was scheduled for the hemilaminectomy, resulted in bradycardia and hypotension, presumably due to the compression of the left atrium. In summary, the authors here discussed the preoperative evaluation and anesthetic management for giant mediastinal neuroblastoma in infants.
