Mitochondrial oxygenation monitoring and acute kidney injury risk in cardiac surgery: A prospective cohort study.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common complication of cardiac surgery and is associated with increased morbidity and mortality. Recent guidelines emphasize the need for new monitoring methods to facilitate targeted CSA-AKI prevention and treatment strategies. In vivo real-time measurement of mitochondrial oxygen tension (mitoPO), could potentially fulfil this role during cardiac surgery, as suggested in our previous pilot study.

Tailoring the Best Positive End-Expiratory Pressure Through Invasive Right Ventricular Pressure-Volume Loops in a Patient Supported by Veno-Arterial Extracorporeal Membrane Oxygenation.

Patients undergoing veno-arterial extracorporeal membrane oxygenation (VA-ECMO) typically suffer from cardiogenic pulmonary edema and lung atelectasis, which can exacerbate right ventricular (RV) dysfunction through an increase in lung elastance and RV afterload. Invasive mechanical ventilation settings, and positive end-expiratory pressure (PEEP) in particular, can help to improve RV performance by optimizing lung recruitment and minimizing alveolar overdistention. In this report, we present a VA-ECMO supported patient in whom in vivo RV pressure-volume (PV) loops were measured during a decremental PEEP trial, leading to the identification of an optimum PEEP level from a cardio-respiratory viewpoint.

Implementation of barcode medication administration (BMCA) technology on infusion pumps in the operating rooms.

Background: Medication administration errors (MAEs) are a major cause of morbidity and mortality. An updated barcode medication administration (BCMA) technology on infusion pumps is implemented in the operating rooms to automate double check at a syringe exchange.

Objective: The aim of this mixed-methods before-and-after study is to understand the medication administrating process and assess the compliance with double check before and after implementation.

Mitochondrial Oxygenation During Cardiopulmonary Bypass: A Pilot Study.

Objective: Adequate oxygenation is essential for the preservation of organ function during cardiac surgery and cardiopulmonary bypass (CPB). Both hypoxia and hyperoxia result in undesired outcomes, and a narrow window for optimal oxygenation exists. Current perioperative monitoring techniques are not always sufficient to monitor adequate oxygenation.

Preoperative anaemia and outcome after elective cardiac surgery: a Dutch national registry analysis.

Background: Previous studies have shown that preoperative anaemia in patients undergoing cardiac surgery is associated with adverse outcomes. However, most of these studies were retrospective, had a relatively small sample size, and were from a single centre. The aim of this study was to analyse the relationship between the severity of preoperative anaemia and short- and long-term mortality and morbidity in a large multicentre national cohort of patients undergoing cardiac surgery.

Rotational Thromboelastometry-Guided Transfusion Protocol to Reduce Allogeneic Blood Transfusion in Proximal Aortic Surgery With Deep Hypothermic Circulatory Arrest.

Objectives: To determine the impact of a rotational thromboelastometry (ROTEM)-guided transfusion protocol on the use of blood products, patient outcomes, coagulation factor concentrates, and costs.

Design: A single-center retrospective cohort study.

Setting: A tertiary university hospital.

A case report of an interrupted inferior vena cava and azygos continuation: implications for preoperative screening in minimally invasive cardiac surgery.

Background: Femoral cannulation is commonly used in minimally invasive cardiac surgery to establish extracorporeal circulation. We present a case with a finding that should be evaluated when screening candidates for minimally invasive cardiac surgery.

Case Summary: A 57-year-old male patient was scheduled for minimally invasive repair of the mitral and tricuspid valve and a MAZE procedure.

Epipleural surgical block and ultrasound-guided erector spinae plane block for analgesia in VATS.

Thoracic surgery is still associated with severe postoperative pain. In this video tutorial, we present 2 techniques that could be used as an additional method in a multimodal postoperative analgesia strategy for video-assisted thoracic surgery. We present the combination of an epipleural surgical infiltration of a local anesthetic with an ultrasound-guided erector spinae plane block.

Increasing cardio-thoracic productivity at Erasmus MC.

The Thoraxcenter of Erasmus MC started an improvement project in 2015 in order to increase the number of open-heart surgeries by 150 for three consecutive years (450 in total, +46%), and to decrease the access time from 12-14 to 2-3 weeks by the end of 2016. This was required to attain economy of scale in a highly competitive market. In this paper we describe the first year of the project, focusing on its structure and interventions taken, resulting in 165 additional open-heart surgeries carried out in 2016 and a significantly shorter access time of 2-3 weeks.

Effectiveness of adherence to a preoperative antiplatelet and anticoagulation cessation protocol in cardiac surgery.

Objectives: Reduction of blood loss after cardiac surgery remains challenging. The effectiveness of adherence to a protocol on cessation of anticoagulants and platelet-inhibiting medications was investigated together with the influence of protocol violations on blood loss after surgery, use of blood products, surgical re-explorations and 30-day mortality.

Methods: Between 2009 and 2013, data were collected prospectively for all elective cardiac surgery procedures in adult patients (n = 1637).

Severe Systolic Anterior Motion After Aortic Valve Replacement and Cox MAZE Surgery.

Surgical aortic valve replacement may be complicated by severe dynamic left ventricular outflow tract obstruction and cardiogenic shock in the postoperative period. We present a patient who developed severe anterior motion following aortic valve and Cox MAZE surgery which necessitated a mitral valve replacement. doi: 10.

[Antidote against local anaesthetic intoxication: new use of lipid emulsion for intravenous administration].

Local anaesthetics are routinely used for several indications, but despite local administration their use may lead to systemic toxicity. The symptoms include numbness of the tongue, dizziness, tinnitus, visual disturbances, muscle spasms, convulsions, coma, and respiratory and cardiac arrest. Recently, an intravenous lipid emulsion was reported to act as a novel potential antidote for systemic toxicity due to local anaesthetics.

Targeting malignant gliomas with a glial fibrillary acidic protein (GFAP)-selective oncolytic adenovirus.

Glial fibrillary acidic protein (GFAP) is an intermediate filament protein abundantly expressed in malignant gliomas. We have constructed a novel oncolytic adenovirus, Ad5-gfa2(B)3-E1, for treatment of these tumors. In this construct, the E1 region is under control of the tissue-specific GFAP promoter (gfa2) with three additional copies of the glial specific 'B' enhancer.

Locoregional delivery of adenoviral vectors.

Unlabelled: The overall median survival of patients with a malignant glioma is <1 y. Because malignant gliomas rarely metastasize outside the skull, locoregional treatment strategies, such as gene therapy, are under investigation. Recently, convection-enhanced delivery (CED) has been presented as a method to improve delivery of large molecules.

Increased glia-specific transgene expression with glial fibrillary acidic protein promoters containing multiple enhancer elements.

The ability to direct transgene expression to astrocytes has become increasingly important as the roles for these cells continue to expand. Promoters consisting of the 5'-flanking region of the human or mouse glial fibrillary acidic protein (GFAP) gene have generally proved satisfactory. However, a more powerful promoter would be advantageous for several applications, such as expression of dominant negative RNAs or proteins, or for gene therapy.
