Residual Pulmonary Hypertension more than 20 Years after Repair of Shunt Lesions

Inhaled Milrinone via HFNC as a Postextubation Cardiopulmonary Elixir: Case Series and Review of Literature

Pulmonary hypertension (PH) often complicates perioperative course following pediatric cardiac surgery, often presenting unique challenges to the attending cardiac anesthesiologist. Apart from difficult weaning from cardiopulmonary bypass, PH can often compound weaning from mechanical ventilation in this postoperative subset. From pathophysiological standpoint, the former can be attributed to concurrent detrimental cardiopulmonary consequences of PH as a multisystemic syndrome. Therefore, with an objective to address the affected systems, that is, cardiac and pulmonary simultaneously, we report combined use of inhaled milrinone (a pulmonary vasodilator) through high-frequency nasal cannula (oxygen reservoir and continuous positive airway pressure delivery device), purported to complement each other's mechanism of action in the management of PH, thereby hastening postoperative recovery. This article additionally presents a nuanced perspective on the advantages of combining the aforementioned therapies and hence proposing the same as a possible “postoperative cardiopulmonary elixir.”
