BACKGROUND: Sepsis-associated brain dysfunction (SABD) is associated with high morbidity and mortality. The pathophysiology of SABD is multifactorial. One hypothesis is that impaired cerebral autoregulation (CAR) may result in brain hypoperfusion and neuronal damage leading to SABD. METHODS: We studied 100 adult patients with sepsis (July 2012-March 2017) (age = 62 [52-71] years; Acute Physiology and Chronic Health Evaluation II score on admission = 21 [15-26])...

BACKGROUND: Inadequate suture tension is a risk factor for the failure of laparotomy closure. Suture tension dynamics in the abdominal wall are still obscure due to the lack of measuring devices. To answer the questions if intra-abdominal hypertension (IAH) influences suture tension in midline laparotomies and if IAH leads to a permanent loss of suture tension, microsensors were applied in a porcine model of IAH. MATERIAL AND METHODS: Microsensors measuring suture tension "on the thread" with a frequency of 1/s were developed and implanted in the suture lines of midline laparotomies in four pigs...

Parkinson's disease, a neurodegenerative disorder, presents with resting tremor, muscle rigidity and bradykinesia. Affecting multiple organ-systems, it's an important cause of peri-operative morbidity. General anaesthesia may deteriorate cardio-pulmonary and neuro-cognitive functions; moreover, medications used may interact with anti-parkinsonian agents. Spinal anaesthesia is usually avoided in Parkinson's disease. However, it offers neurologic monitoring and less surgical stress response and avoids complications of general anaesthesia...

The hemodynamic effects of mechanical ventilation can be grouped into three clinically relevant concepts. First, since spontaneous ventilation is exercise. In patients increased work of breathing, initiation of mechanical ventilatory support may improve O2 delivery because the work of breathing is reduced. Second, changes in lung volume alter autonomic tone, pulmonary vascular resistance, and at high lung volumes compress the heart in the cardiac fossa similarly to cardiac tamponade. As lung volume increases so does the pressure difference between airway and pleural pressure...

BACKGROUND: Acute heart failure refractory to medical therapy is a major cause of morbidity and mortality. The Aortix device (Procyrion Inc) is a percutaneously delivered entrainment pump positioned in the descending aorta. METHODS AND RESULTS: Using the newest generation Aortix device in 8 adult male Yorkshire swine, we tested the hypothesis that positioning in the abdominal aorta may provide superior hemodynamic effects than thoracic positioning in a swine model of postinfarct left ventricular injury...

BACKGROUND: Laparoscopic abdominal surgery has been widely used to reduce the length of hospital stay and complications from open abdominal surgery. During the operation, the creation of pneumoperitoneum is used for better visualization of the operating field. However, the effect of pneumoperitoneum on kidney function is unknown. We aimed to identify risk factors and predictors associated with AKI development following laparoscopic abdominal surgery. METHODS: A single-center prospective cohort study of laparoscopic abdominal surgery patients between June 2012 and December 2013...

An abdominal aortic aneurysm (AAA) is a localized dilatation of the infrarenal aorta. AAA is a multifactorial disease, and genetic and environmental factors play a part; smoking, male sex and a positive family history are the most important risk factors, and AAA is most common in men >65 years of age. AAA results from changes in the aortic wall structure, including thinning of the media and adventitia due to the loss of vascular smooth muscle cells and degradation of the extracellular matrix. If the mechanical stress of the blood pressure acting on the wall exceeds the wall strength, the AAA ruptures, causing life-threatening intra-abdominal haemorrhage - the mortality for patients with ruptured AAA is 65-85%...

PURPOSE: Pulmonary recruitment and positive end-expiratory pressure (PEEP) titrated according to minimal static elastance of the respiratory system (PEEPEstat,RS ) compared to PEEP set according to the ARDSNetwork table (PEEPARDSNetwork ) as a strategy to prevent ventilator-associated lung injury (VALI) in patients with acute respiratory distress syndrome (ARDS) increases mortality. Alternatively, avoiding negative end-expiratory transpulmonary pressure has been discussed as superior PEEP titration strategy...

Diffusion-weighted magnetic resonance imaging (DW-MRI) uses water as contrast and enables the study of perfusion in many organs simultaneously in situ. We used DW-MRI in a sepsis model, comparing abdominal organs perfusion with global hemodynamic measurements and inflammation. Sixteen anesthetized piglets were randomized into 3 groups: HighMAP (mean arterial pressure, MAP > 65 mmHg), LowMAP (MAP between 50 and 60 mmHg) and Healthy Controls (HC). Sepsis was obtained with endotoxin and the desired MAP maintained with noradrenaline...
