Prothrombin Complex Concentrates in Pediatric Cardiac Surgery: The Current State and the Future.
After decades of practice of pediatric cardiac surgery, postoperative bleeding due to the immaturity of hemostasis, hemodilution, and hypothermia remains a concern. Recently, a new approach for adult coagulopathy after bypass has emerged. Prothrombin complex concentrates (PCCs), designed to treat bleeding in hemophilia patients, are safely and efficiently used off label for hemorrhage after bypass. However, optimal dosing, indications and contraindications, and laboratory tests to assess the efficacy of PCC use in children have not yet been established. This literature review outlines the challenges of bypass-related coagulopathy, the pharmacology, and the experience in use of PCCs, with a focus on their potential in pediatric cardiac surgery. ⋯ Extensive, high-quality research is warranted to fill in the gaps of knowledge regarding using PCCs in pediatric cardiac practice.

In operations for acute type A aortic dissection with open technique in elderly patients and patients with long-term treatment of anticoagulation, the transverse pericardial sinus was routinely closed before the graft implantation. With the aid of both a bovine pericardial patch covering the pericardial recess between the superior caval vein and the pulmonary artery and an opening in the left inner side of the superior caval vein, this prophylactic transverse pericardial sinus closure could make autotransfusion of blood loss into the central venous system possible to deal with the diffuse oozing from the suture line.

We assessed the impact of preoperative Staphylococcus aureus screening and targeted decolonization on the incidence of postoperative methicillin-resistant S aureus (MRSA) colonization, intensive care unit MRSA transmission, and surgical site infections in cardiac surgery patients. ⋯ Preoperative S aureus screening with targeted decolonization was associated with reduced MRSA colonization, transmission, and surgical site infections. Duration of preoperative therapy correlated with decreased frequency of postoperative MRSA colonization.

Despite the relatively high sensitivity of fluorodeoxyglucose-positron emission tomography (PET) and computed tomography (CT) scans used for staging of non-small cell lung cancer (NSCLC), a subset of patients with peripherally located clinical T1a N0 will be upstaged due to pathologic nodal disease. It is important to study this risk of upstaging, especially if local treatments, such as wedge resection or stereotactic body radiation therapy, are potential treatment modalities. Our aim was to determine the rate of pathologic N1/N2 disease in peripherally located clinical T1a N0 NSCLC and predictive factors for nodal metastasis. ⋯ High PET-SUVmax of the primary tumor is associated with elevated risk of nodal disease for peripheral T1a N0 NSCLC patients. Further diagnostic procedures, such as endobronchial ultrasound, may be required, especially if wedge resection or stereotactic body radiation therapy are being considered.

This was a retrospective study to determine whether lack of furosemide responsiveness (LFR) predicts acute kidney injury (AKI) after cardiopulmonary bypass surgery in infants. ⋯ After correcting serum creatinine for fluid balance and adjusting for surgical complexity, LFR performs fairly at 2 hours, whereas at 6 hours, LFR is a good AKI predictor. Prospective studies are needed to validate whether diuretic responsiveness predicts AKI.
