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 >>

Factors influencing the bias between blood gas analysis versus central laboratory hemoglobin testing. A secondary analysis of a randomized controlled trial.

Linda Tanner, Simone Lindau, Markus Velten, Tobias Schlesinger, Maria Wittmann, Peter Kranke, Kira Berg, Florian Piekarski, Christoph Füllenbach, Suma Choorapoikayil, Dirk Hasenclever, Kai Zacharowski, Patrick Meybohm,

<h4>Background</h4>Anemia is the most important complication during major surgery and transfusion of red blood cells is the mainstay to compensate for life threating blood loss. Therefore, accurate measurement of hemoglobin (Hb) concentration should be provided in real-time. Blood Gas Analysis (BGA) provides rapid point-of-care assessment using smaller sampling tubes compared ... Read more >>

Christoph Martin, Florian Piekarski, Haitham Mutlak, Richard Schalk, Daniel Dubinski, Kai Zacharowski, Florian Raimann,

BACKGROUND:The i-gel mask is a second-generation, single-use supraglottic airway device which does not have an inflatable cuff. The cuff consists of a thermoplastic elastomer and its mechanism of sealing still remains unclear. Various theories such as temperature-dependent changes in hardness and volume expansion as well as fluid absorption have been ... Read more >>

Patrick Meybohm, Simone Lindau, Sascha Treskatsch, Roland Francis, Claudia Spies, Markus Velten, Maria Wittmann, Erdem Gueresir, Christian Stoppe, Ana Kowark, Mark Coburn, Sixten Selleng, Marcel Baschin, Gregor Jenichen, Melanie Meersch, Thomas Ermert, Alexander Zarbock, Peter Kranke, Markus Kredel, Antonia Helf, Rita Laufenberg-Feldmann, Marion Ferner, Eva Wittenmeier, Karl-Heinz Gürtler, Peter Kienbaum, Marcel Gama de Abreu, Michael Sander, Michael Bauer, Timo Seyfried, Matthias Gruenewald, Suma Choorapoikayil, Markus M Mueller, Erhard Seifried, Oana Brosteanu, Holger Bogatsch, Dirk Hasenclever, Kai Zacharowski, ,

BACKGROUND:Perioperative anaemia leads to impaired oxygen supply with a risk of vital organ ischaemia. In healthy and fit individuals, anaemia can be compensated by several mechanisms. Elderly patients, however, have less compensatory mechanisms because of multiple co-morbidities and age-related decline of functional reserves. The purpose of the study is to ... Read more >>
