BACKGROUND: In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures. METHODS: Data from patients with pre-operative LVEF ≤40 % undergoing cardiac surgery at a university hospital were reviewed and analyzed...

BACKGROUND: Simulation-based training (SBT) has developed into an established method of medical training. Studies focusing on the education of medical students have used simulation as an evaluation tool for defined skills. A small number of studies provide evidence that SBT improves medical students' skills in the clinical setting. Moreover, they were strictly limited to a few areas, such as the diagnosis of heart murmurs or the correct application of cricoid pressure. Other studies could not prove adequate transferability from the skills gained in SBT to the patient site...

Graft and patients survival are the main goal of anesthesiological management in patients undergoing liver transplantation (LT). Even if anesthesiological practice sustained major developments over time, some evidence-based intraoperative strategies have not yet been widely applied. The aim of this review was to summarize intraoperative anesthesiological strategies which could have the potential to improve LT graft and/or recipient survival. Monitoring must be as accurate as possible in order to manage intraoperative hemodynamic changes...

BACKGROUND: Current respiratory monitoring technologies such as pulse oximetry and capnography have been insufficient to identify early signs of respiratory compromise in nonintubated patients. Pulse oximetry, when used appropriately, will alert the caregiver to an episode of dangerous hypoxemia. However, desaturation lags significantly behind hypoventilation and alarm fatigue due to false alarms poses an additional problem. Capnography, which measures end-tidal CO2 (EtCO2) and respiratory rate (RR), has not been universally used for nonintubated patients for multiple reasons, including the inability to reliably relate EtCO2 to the level of impending respiratory compromise and lack of patient compliance...

Respiratory insufficiency type 2 (ventilatory failure) is characterized by hypercapnia due to alveolar hypoventilation. Therefore, the monitoring of pCO2 is essential for diagnostic and surveillance purposes. Various techniques which differ in the way of measurement (e.g., invasive/noninvasive, continuous/noncontinuous) and their indication are available. Arterial blood gas analysis (ABG) as an invasive procedure is the gold standard procedure and is mostly used in emergency medicine or intensive care units (ICUs)...

Anesthesiological management of patients with Takotsubo syndrome (TTS) is a challenge of questions related to physiopathology, prognosis, and trigger causes. Relative rarity of this disease and lack of wide literature do not allow to state any negative or positive effect of the variety of drugs available for anesthesia. The authors report a case of a woman with a clear diagnosis of TTS and anxiety disorder, who underwent to cataract extractions at both eyes at two different times. Clinical management is described, from preoperative assessment until discharge of the patient...

Clinical monitoring is an essential part of the profession of anesthesiology. It would therefore be impossible to review all articles published in the Journal of Clinical Monitoring and Computing that are relevant to anesthesia. Because other reviews will address monitoring of the respiratory and cardiovascular system, the current review will limit itself to topics uniquely related to anesthesia. The topics are organized according to the chronological order in which an anesthetic proceeds: secure the airway; ventilate and deliver anesthetic gases; monitor vital organ function and anesthetic depth; and ensure analgesia during/after emergence from anesthesia (locoregional anesthesia and pain control)...

Sedation in locations outside the operating room (OR) is common. Guidelines for safe patient monitoring have been updated by the American Society of Anesthesiology to include monitoring of ventilation and/or carbon dioxide (CO2). Although technologies exist to monitor these variables, the quality and/or availability of these measurements in non-OR settings is not optimal. This quality improvement project assessed the value of impedance technology for monitoring minute ventilation (MV) compared to standard end-tidal monitoring of CO2 (ETCO2)...

PURPOSE OF REVIEW: A major cause of hypoxemia in anesthesia is ventilation-perfusion (VA/Q) mismatch. With more advanced surgery and an aging population, monitoring of VA/Q is of increasing importance. RECENT FINDINGS: The classic multiple inert gas elimination technique has been simplified with a new approach based on mass spectrometry. VA/Q distributions can also be measured, at the bedside, by varying inspired oxygen concentration. MRI, 3-dimensional single photon emission computed tomography, positron emission tomography, and electrical impedance tomography enable imaging of perfusion and ventilation, and in some of the techniques also the distribution of inflammation...
