Cardiopulmonary bypass and extracorporeal membrane oxygenation are commonly used adjuncts to lung transplantation. These techniques are not without associated morbidity and mortality, and the surgeon must be aware of the possibility of aberrant anatomy that could lead to vascular injury during cannulation. In this report, we describe a patient with congenital absence of the inferior vena cava undergoing lung transplantation who required perioperative cardiopulmonary support. A percutaneous dual lumen cannula, Protek Duo, was connected in an Oxy-RVAD configuration to provide right ventricular and oxygenation support both intraoperatively and postoperatively to this patient.
Objectives: Though guidelines are set by the American Board of Thoracic Surgery for the operative cases that cardiothoracic surgery residents must perform to be board-eligible, no such recommendations exist to assess competency for the wide range of high-risk bedside procedures. Our department created and implemented a multi-disciplinary developed course designed to standardize common high-risk bedside procedures and credential our residents. The aim of this study was to survey the attitudes of residents to and query the efficacy of such a course. Methods: The course was designed with the goal of standardizing endotracheal intubation, arterial line insertion (radial and femoral), central venous line insertion, pigtail tube thoracostomy and nasogastric tube placement. The course consisted of an online module followed by a 4-hour hands on simulation session. Knowledge based pre and post evaluations were administered as well as Likert based survey regarding multiple aspects of the residents’ perceptions of the course and the procedures. Results: Twenty-three (7 traditional and 16 integrated) cardiothoracic surgical residents participated in the course. Residents reported that 48% of the time, bedside procedures were historically taught by other trainees rather than faculty. All residents endorsed increased standardization of all procedures after the course. Likewise, residents showed increased confidence in all procedures except for pigtail and thoracentesis as well as nasogastric tube placement. 43.5% of the participants demonstrated improvement in the pre and post-test knowledge-based evaluations. ConclusionCardiothoracic residents have favorable attitudes towards standardization and credentialing for high risk bedside procedures and utilizing such courses may help standardize procedural techniques.
Extracorporeal membrane oxygenation (ECMO) is a technology that has allowed for further cardiopulmonary support in the setting of respiratory failure refractory to mechanical ventilation. While it has evolved since its first description, one area of improvement continues to be its implementation. With advancements in cannulation techniques, in recent years, there has been a plethora of new cannulas that has been introduced to the market. For urgent venous-venous cannulation, the right internal jugular vein along with either femoral veins remain the most utilized strategy due to minimal need for imaging support. This allows for safe bedside cannulation. However, as the number of days of ECMO support continue to increase bridging patients to an easier to ambulate and more comfortable cannulation strategy is preferred. Therefore, we describe a method for bridging right jugular-femoral cannulation to left subclavian placement of the CrescentTM Dual Lumen Catheter without interrupting ECMO support.
