Postoperative non-invasive assessment of pulmonary vascular resistance using Doppler echocardiography.
2011
Non-invasive monitoring of pulmonary vascular resistance (PVR) in postoperative cardiac surgery patients might be useful, particularly for management of pulmonary hypertension. For this purpose, we sought to assess Doppler echocardiography in the intensive care setting. In 73 patients, hemodynamics was measured using both, invasive gold standard (pulmonary artery catheter), and non-invasively by Doppler echocardiography. Four Doppler parameters: (1) tricuspid regurgitant velocity/time-velocity-integral of right ventricular outflow tract (TRV/VTI(RVOT)), (2) tricuspid annular systolic velocity (S'), (3) tricuspid annular strain, and (4) tricuspid annular strain rate, were compared with invas…
Ventilation workshop - a new concept
2000
The use of simulator technology to practise crisis resource management or to train standardised procedures in anaesthesia is a proved concept, although its setup in clinical practice is still in progress. To get a better understanding of the complex pathophysiological and clinical relations in the pulmonary system and the kind of alterations that could be induced by changing the ventilation of an intensive care unit patient, we modified the current concept. We created a workshop, which employs more than just the simulator training in the classical sense. During this workshop the participants attend one patient from admission to an emergency room, until discharge from an intensive care unit …
Hemodynamic monitoring and management in patients undergoing high risk surgery: a survey among North American and European anesthesiologists
2011
Abstract Introduction Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. Methods A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Results Overall,…
Influence of dopexamine on hemodynamics, intramucosal pH, and regulators of the macrocirculation and microcirculation in patients undergoing abdomina…
2000
Abstract Objective: To investigate whether dopexamine hydrochloride beneficially influences splanchnic perfusion and regulators of the macrocirculation and microcirculation in patients undergoing surgery of the abdominal aorta. Design: Prospective, blinded, and randomized study. Setting: University-affiliated hospital. Participants: Twenty patients undergoing elective abdominal aortic surgery. Interventions: The patients were randomized to one of two groups. In the dopexamine group (DOP, n = 10), dopexamine, 1 μg/kg/min, was started before surgery and continued for 24 hours. In the control group (COG, n = 10), patients received saline solution as placebo. Extensive hemodynamic monitoring wa…
