Meningioma Surgery in Patients ≥70 Years of Age: Clinical Outcome and Validation of the SKALE Score.

Daniel Monden, Florian J Raimann, Vanessa Neef, Daniel Dubinski, Florian Gessler, Fee Keil, Marie-Thérèse Forster, Michael W Ronellenfitsch, Patrick N Harter, Thomas M Freiman, Elke Hattingen, Volker Seifert, Christian Senft, Peter Baumgarten,

Along with increasing average life expectancy, the number of elderly meningioma patients has grown proportionally. Our aim was to evaluate whether these specific patients benefit from surgery and to investigate a previously published score for decision-making in meningioma patients (SKALE). Of 421 patients who underwent primary intracranial meningioma resection between ... Read more >>

Current concepts in the evaluation and management of preoperative anemia.

Vanessa Neef, Suma Choorapoikayil, Florian Piekarski, Tobias Schlesinger, Patrick Meybohm, Kai Zacharowski,

<h4>Purpose of review</h4>In the past years, patient blood management (PBM) has evolved to improve patient's care and safety. Anemia is one of the most common medical diseases in the world and is an independent risk factor for morbidity and mortality. Iron deficiency is the main cause for anemia and constitutes ...

Local Anesthetic-Induced Central Nervous System Toxicity during Interscalene Brachial Plexus Block: A Case Series Study of Three Patients.

Daniel Spitzer, Katharina J Wenger, Vanessa Neef, Iris Divé, Martin A Schaller-Paule, Kolja Jahnke, Christian Kell, Christian Foerch, Michael C Burger,

Local anesthetics are commonly administered by nuchal infiltration to provide a temporary interscalene brachial plexus block (ISB) in a surgical setting. Although less commonly reported, local anesthetics can induce central nervous system toxicity. In this case study, we present three patients with acute central nervous system toxicity induced by local ... Read more >>

The visually estimated blood volume in scaled canisters based on a simulation study.

Lara Gerdessen, Vanessa Neef, Florian J Raimann, Kai Zacharowski, Florian Piekarski,

<h4>Background</h4>The most common technique used worldwide to quantify blood loss during an operation is the visual assessment by the attending intervention team. In every operating room you will find scaled suction canisters that collect fluids from the surgical field. This scaling is commonly used by clinicians for visual assessment of ... Read more >>

Audit of international intraoperative hemotherapy and blood loss documentation on anesthetic records.

Florian Piekarski, George Zhong, Vanessa Neef, Jan Kloka, Florian Wunderer, Patrick Meybohm, Kai Zacharowski, Florian J Raimann,

<h4>Background</h4>Anesthetic records facilitate information transmission to the next healthcare professional and should contain all relevant information of perioperative care. While most anesthesia societies provide guidelines for record content, important topics like hemotherapy and hemostatic therapy are not well represented. We considered the quality of anesthetic records with regard to the ... Read more >>

The association between intraoperative cell salvage and red blood cell transfusion in cardiac surgery - an observational study in a patient blood management centre.

Vanessa Neef, Linda Vo, Eva Herrmann, Chris Triphaus, Leonie Judd, Andreas Winter, Kai Zacharowski, Suma Choorapoikayil, Patrick Meybohm,

<h4>Introduction</h4>Cell salvage (CS) is an integral part of patient blood management (PBM) and aims to reduce allogeneic red blood cell (RBC) transfusion.<h4>Material and methods</h4>This observational study analysed patients scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CPB) between November 2015 and October 2018. Patients were divided into a CS group (patients ... Read more >>

Implementation of an anaemia walk-in clinic: Feasibility and preliminary data from the Orthopedic University Hospital.

Vanessa Neef, David Meisenzahl, Paul Kessler, Florian J Raimann, Florian Piekarski, Suma Choorapoikayil, Christoph Fleege, Kai D Zacharowski, Patrick Meybohm, Andrea Meurer,

<h4>Background</h4>Approximately one in three patients suffers from preoperative anaemia. Even though haemoglobin is measured before surgery, anaemia management is not implemented in every hospital.<h4>Objective</h4>Here, we demonstrate the implementation of an anaemia walk-in clinic at an Orthopedic University Hospital. To improve the diagnosis of iron deficiency (ID), we examined whether reticulocyte ... Read more >>

Characterization of neonates born to mothers with SARS-CoV-2 infection: Review and meta-analysis.

Vanessa Neef, Horst Buxmann, Holger F Rabenau, Kai Zacharowski, Florian J Raimann,

Characterization of neonates born to mothers with SARS-CoV-2 infection has been partially carried out. There has been no systematic review providing a holistic neonatal presentation including possible vertical transmission. A systematic literature search was performed using PubMed, Google Scholar and Web of Science up to June, 6 2020. Studies on ... Read more >>

Do we visually estimate intra-operative blood loss better with white or green sponges and is the deviation from the real blood loss clinically acceptable? Results from a simulated scenario study.

Florian Piekarski, Lara Gerdessen, Elke Schmitt, Linda Tanner, Florian Wunderer, Vanessa Neef, Patrick Meybohm, Kai Zacharowski, Florian Jürgen Raimann,

<h4>Background</h4>The intraoperative blood loss is estimated daily in the operating room and is mainly done by visual techniques. Due to local standards, the surgical sponge colours can vary (e.g. white in US, green in Germany). The influence of sponge colour on accuracy of estimation has not been in the focus ... Read more >>

Comparison of common perioperative blood loss estimation techniques: a systematic review and meta-analysis.

Lara Gerdessen, Patrick Meybohm, Suma Choorapoikayil, Eva Herrmann, Isabel Taeuber, Vanessa Neef, Florian J Raimann, Kai Zacharowski, Florian Piekarski,

Estimating intraoperative blood loss is one of the daily challenges for clinicians. Despite the knowledge of the inaccuracy of visual estimation by anaesthetists and surgeons, this is still the mainstay to estimate surgical blood loss. This review aims at highlighting the strengths and weaknesses of currently used measurement methods. A ... Read more >>

Quantification of Intraoperative Blood Loss in a Simulated Scenario Using a Novel Device.

Florian Piekarski, Lara Gerdessen, Elke Schmitt, Benjamin Friedrichson, Vanessa Neef, Patrick Meybohm, Kai Zacharowski, Florian J Raimann, Florian Wunderer,

<h4>Background</h4>Particularly for protracted bleeding situations, the realization of a relevant blood loss is necessary for early initiation of therapy to avoid hemodynamic instability and shock. The frequently used visual assessment of blood loss is known to be incorrect. An innovative option to address this problem is a mobile application using ... Read more >>
