Filter by:The purpose of this study is to evaluate the stroke volume variation measured by both methods: transpulmonary thermodilution and electrical impedance tomography (EIT), during fluid responsiveness maneuvers and after fluid replacement in the immediate postoperative of coronary artery bypass grafting (CABG) patients. Patients will be hemodinamically monitored with the VolumeView set in combination with EV1000 clinical platform and the display of valuable volumetric parameters (Edwards Lifesciences, California, USA). Simultaneoulsy, patients will be monitored with Enlight Electrical Impedance Tomography (Timpel, São Paulo, Brazil). Hemodynamic data will be assessed at baseline 1, one minute after the passive leg raising maneuver, after PEEP increment, and after 500 mL of Lactated Ringer's (bolus infusion). Blood gases sample will be assessed before and immediatly after the protocol.
This study is designed to help decide how much intravenous (IV) fluid should be given to pediatric trauma patients. No standard currently exists for managing fluids in critically ill pediatric trauma patients, and many fluid strategies are now in practice. For decades, trauma patients got high volumes of IV fluid. Recent studies in adults show that patients actually do better by giving less fluid. The investigators do not know if this is true in children and this study is designed to answer that question and provide guidelines for IV fluid management in children after trauma.
The amount of fluids characterized as non-resuscitation fluids given to ICU patients are likely to be high and will probably have a substantial impact on the total amount of fluid administered to ICU patients daily. It will most likely also influence on the total fluid balance and the negative outcome of fluid overload. The aim of our study is to investigate the amount of fluid given as maintenance fluids in the ICU and the impact of this fluid on total fluid balance.
This study will describe the change of mitochondrial oxygen tension (mitoPO2) compared to traditional parameters of oxygenation and oxygen balance in the first 24 hours of septic patients admitted to the intensive care unit of an academic hospital. The mitoPO2 will be measured on prespecified measurement moments in the ICU. With each measurement moment, arterial and central venous blood gasses will be taken too.
Perioperative fluid therapy has undergone a huge change in clinical practice in recent years. The patterns of replacement and / or restoration of volemia described in the classic anaesthesiology books were supported by weak scientific evidence, and a paradigm shift in perioperative fluid therapy based on aspects such as increased mortality associated with an excessively positive balance of fluids in the perioperative period, evidences related to the non-existence of the third non-anatomical space and the need to preserve the capillary endothelium and its glycocalyx. On the other hand, advances in technology, through the availability of less invasive monitoring systems, capable of determining dynamic parameters related to blood volume that allow predicting the response to volume management, have provided much more adequate monitoring and simple to guide such intravenous volume restoration. Following all these changes different guidelines and recommendations have been published in recent years with the intention of clarifying the current evidence and facilitate the correct use of fluid therapy to clinicians, but despite this the fact is that today the investigators still do not have information on how fluid therapy is administered in daily practice, so the section of Hemostasis, Transfusion Medicine and Fluid Therapy of SEDAR, considered it necessary to evaluate the clinical practice of fluid therapy in the perioperative period through the Fluidday study.
The investigators will study the correlation between the lenght of the fasting before surgery and the need to replenish with intra-venous fluids in children, evaluated with 3 measures of the aortic Integral Time Velocity with transthoracic echocardiography.
Reduced urinary output is a common postoperative issue for patients going through major surgery such as pancreatic surgery. Commonly this is treated by increasing fluid administration to the patients and sometimes also diuretics. However, overloading patients with fluid also have several risks and known complications. Studies have also shown that a short period of decreased urinary output in the postoperative period do not have an increased incidence of acute renal failure. The aim of our study is to investigate the difference in renal function and postoperative complications associated with fluid overload on these patients that are randomized to either receiving a fluid bolus directly when urinary output decreases or to await for a maximum of four hours to see if urinary output increases spontaneously.
The study aim is to investigate if preoperative volume bolus based on lean body weight could preserve mean arterial pressure during target controlled infusion of anaesthesia (TCI) or rapid sequence induction of anaesthesia (RSI) in non-cardiac, non-morbidly obese surgery.
Whether a fluid protocol aiming for protecting vital organ perfusion or fluid restriction is favorable to post-craniotomy outcomes such as brain edema remains uncertain. To our knowledge, there has been no extensive and quantitative analysis of brain edema following SVV-based GDFT in neurosurgical patients with malignant supratentorial glioma. So the study aims to observe the effect of the stroke volume variation-based GDFT on the postoperative brain edema and decrease the incidence of postoperative complications in neurosurgical patients with malignant supratentorial gliomas.
Pulse wave Transit time (PWTT) is a parameter calculated from ECG and pulseoximeter. It is supposed to help assessing the preload Status and guide intraoperative fluid therapy. This Project aims to validate the benefit of PWTT assessment in an observational clinical fluid study. In case of hypovolemia, patients will receive a fluid Bolus and hemodynamic data from clinical Standard Monitoring, esophageal doppler and PWTT will be recorded before and after the fluid Bolus. Receiver operating characteristic (ROC) curve will be used to determine the validity of PWTT as indicator for fluid responsiveness and its cut off value.
