Filter by:Beta-blockers are useful tools for the prevention of hemodynamic instability in the manipulation of airways. The main objective of the present study is to evaluate the effectiveness of using esmolol in attenuating hemodynamic responses at the time of tracheal extubation, by assessing the incidence of tachycardia in relation to placebo.
Hemodynamic unstability, defined by macrocirculation and/or microcirculation dysfunction or alteration is common in critically ill pediatric patients. The initial treatment of hemodynamically unstable patient is the fluid resuscitation (fluid challenge therapy). However, the stabilization of hemodynamics only with fluid resuscitation can be achieved in less than 50% pediatric patients. In case of persistent hypotension (defined as mean arterial pressure below 65 mmHg, or by the formula - 55 + 1,5 x age in years), or in case of persistent lactate levels and base deficit elevation is the catecholamine therapy method of choice in case of sufficiently restored intravascular volume. In adult patients, the drug of choice (the first line therapy of persistent hypotension) is considered norepinephrine (based on evidence-based data). The norepinephrine is administered intravenously in form of continuous infusion, with the dose adjusted to the target level of mean arterial pressure (MAP). It should be preferably administered through the central venous catheter to minimize the complications associated with the damage of the peripheral vein wall damage in case of administered into the peripheral vein. Due to lack of evidence-based data (EBM) for pediatric population, there is still significant heterogenity of clinical practice and dobutamin, dopamine, norepinephrine and epinephrine are being used for hemodynamically unstable pediatric patient.
This study aims to provide myriad of physiological parameters in patients admitted in an internal medicine department, and which are defined as being in an increased risk of clinical deterioration within the first 72-hours after admission. The investigators will also conduct a retrospective comparison between physiological changes in patients who did deteriorate to those who did not. This will form the basis for the development of an algorithm for early prediction and warning of physiological and clinical deterioration during the first 72-hours of admission.
The aim of this study is to compare hemodynamic monitoring using the invasive PiCCO device to the BB-613PW wireless, non-invasive PPG-based device, in critically ill patients within the ICU, suffering from hemodynamic instability and in need of vasopressor support. Data will be gathered prospectively and analysed retrospectively.
The "Hypotension Prediction Index (HPI)" was established by the Edwards Lifescience Company (Irvine, California, USA) and is CE certified. As part of the Edwards Acumen Decision-Support-Software-Suite the HPI is supported by the minimal invasive FloTrac Sensor. The HPI displays the probability of an occurring hypotension. The software was established with the help of 20.000 analyzed patient events. If the upper limit of the HPI is reached, the software is alarming the treating physician 8. At the university hospital of Giessen HPI analyses are used in the daily clinical routine as well as for scientific purposes. Preliminary data of the HPI-I-Trial ("Influence of the Hypotension Prediction Index on the number and duration of intraoperative hypotension in primary hip-endoprothetic replacement", University Hospital of Giessen) included patients, which underwent hip-endoprothetic replacement surgery and revealed that the use of HPI with a goal directed therapy (GDT) protocol compared to standard care significantly reduced the incidence and duration of intraoperative hypotension. Therefore HPI with GDT might reduce the incidence of hypotension related complications in a sicker patient cohort. The aim of the study is to investigate whether a goal directed treatment according to the Hypotension Prediction Index compared to standard care can reduce the incidence of intraoperative hypotension in patients under single lung ventilation.
This study will investigate the potential of guiding remifentanil analgesia during cardiac and vascular surgery in moderate to high risk patients requiring general anesthesia.
This prospective observational study will include critically ill patients with hemodynamic compromise. It will compare passive leg raising and a mini volume challenge (MVC) carried out on every patient sequentially. The endogenous release of stress hormones will also be assayed in order to investigate their modifying effect on the hemodynamic reaction of the participants. The effect of fluid resuscitation on renal perfusion will also be assessed and the data compared with the release of cystatin C.
Many surgical procedures are performed using the laparoscopic approach. However, insufflation of the abdomen (pneumoperitoneum) has detrimental hemodynamic effects. The investigators intend to investigate the effect of deep neuromuscular block and nociception guided anaesthesia on hemodynamic variables during pneumoperitoneum for lower abdominal laparoscopic surgery.
The ATLANTIS-study was designed to determine the safety of a full paracentesis in patients with malignant ascites due to ovarian cancer. The underlying hypothesis states, that full paracentesis does not impair safety, compared to fractioned paracentesis with clamping of the drain. Half of the patients will receive a full paracentesis, while the other half will receive fractioned paracentesis with clamping of the drain after 3 liters of ascites was evacuated. All patients receive extensive monitoring of hemodynamics and kidney function.
The patient's clinical care will not be altered apart from an the use of a non-invasive monitor for a short time, without any biological sample acquisition, or follow-up. This is low risk. The device works through a complex pressure measurement in the fingers and by slightly squashing the fingers it can cause minor impairments to circulation. This represents a very small risk. To mitigate this risk the investigators will exclude patients with impaired circulation to the fingers and fingers will be monitored. The approach is necessarily on the day of surgery and for many people this is an anxious time. The investigators have a lot of experience of approaching patients on the day of surgery for providing consent for observational studies - the investigators use caution and sensitivity. The investigators do not approach patients who the clinical team consider anxious or where there is significant pressure on time.
