Case ReportsRepair of ventricular septal defect in a child with severe pulmonary hypertension-response to inhaled nitric oxide.
Nitric oxide (NO), was administered successfully, to a child with severe pulmonary hypertension, following surgical repair of a large ventricular septal defect. Inhalation of NO, 20-25 parts per million (ppm) was continued for 24 h, resulting in mean pulmonary artery pressure (PAP) of 25 mmHg and permitting a reduction in both ventilatory and inotropic support. ⋯ An immediate and dramatic increase in PAP occurred. A similar pattern resulted on further attempts, demonstrating the extreme sensitivity of the pulmonary vasculature to the effects of inhaled low dose NO and the selectivity of the response.

Case ReportsMassive blood loss during tonsillectomy in a child with congenital venous malformation.
Tonsillectomy and adenoidectomy have become frequently performed outpatient procedures and are generally considered to have a low morbidity profile. Postoperative haemorrhage remains a rare but important complication, while intraoperative uncontrollable bleeding is extremely uncommon. ⋯ Preoperative/preanaesthetic nasopharyngoscopic exam and magnetic resonance imaging did not reveal vascular prominence of the tonsils. Preoperative consideration of angiography or magnetic resonance angiography may be prudent to avoid this potentially fatal complication.
