Filter by:The RADAR-Canada trial is a pilot RCT undertaken to assess the acceptability of, compliance with, and biologic consequences of a deresuscitation protocol designed to expedite the removal of excess interstitial fluid in patients who remain in a positive fluid balance following admission to an intensive care unit (ICU).
Controlling the amount of fluids given to patients in perioperative setting can significantly influence their outcomes.
Feasibility and safety of targeting neutral vs liberal fluid balance in traumatic brain injured patients: a phase II randomized controlled trial
Fluid overload is a common feature of diseases such as heart failure and kidney injury, which can lead to pulmonary edema or even death if not treated in time. In order to rapidly relieve fluid overload in patients, a wearable filtrating artificial kidney device was developed. The purpose of this study is to evaluation of the precision, security, and operability of wearable filtrating artificial kidney device for on-site medical rescue.
Acute microcirculatory perfusion disturbances is common in critical illness and associated with increased morbidity and mortality. Recent findings by our group showed that microcirculatory perfusion is disturbed during cardiac surgery with cardiopulmonary bypass (CPB) and remain disturbed up to 72 (seventy two) hours after surgery. A cardiopulmonary bypass is a machine which takes over heart and lung function, during the procedure. The disturbed microcirculation is associated with organ dysfunction induced by cardiac surgery using CPB, which is frequently seen (up to forty two percent, 42%) and results in a six-fold increase in mortality rate. The underlying cause of disturbed microcirculation is a higher endothelial permeability and vascular leakage and are a consequence of systemic inflammation, hemodilution (dilution of blood), hypothermia and hemolysis (breakdown of red blood cells). To gain the knowledge regarding disturbed microcirculation the investigators previously showed that hemodilution attributes to this disturbed perfusion. Hemodilution lowers colloid oncotic pressure (COP). Also, COP is affected by free hemoglobin, which increases with hemolysis and attributes to a disturbed microcirculation following CPB. This is interesting, as to the best of our knowledge, the effect of minimizing hemodilution and hemolysis during cardiac surgery on the microcirculatory perfusion has never been investigated, but could be the key factor in reducing organ dysfunction.
The size of the inferior vena cava (IVC) using point of care ultrasound is used in resuscitation of patients who are critically ill and is now being used as a standard part of resuscitation in many clinical situations. Multiple factors can effect the size of the IVC including the type of oxygen devices the patient is currently on. In the ICU setting, the use of High Flow Nasal Cannula (HFNC) is often used to help in patients who are critically ill. There is some evidence to suggest that the use of HFNC can effect the size of the IVC measurement but the extent of the effect has not been well characterized. The purpose of this study is to determine the effect HFNC has on the size of the IVC measured using a point of care ultrasound.
The functional hemodynamic test (FHT) called passive leg raising (PLR) has been successfully used for assessing the fluid responsiveness in ICU patients since 2009 and its reliability has been confirmed by three large meta-analyses. However, the PLR is not usually practicable in the OR. A lot of different FHTs have been proposed, as alternative to the PLR, in ICU and, more recently, OR. These tests could be basically subdivided in two groups. A subgroup of FHTs is based on sudden and brief variations of the mechanical ventilation to induce a change in right ventricle preload and/or after load and, as consequence, of left ventricle SV. A second subgroup aims at testing the increase in SV after the rapid administration of a small aliquot of the predefined FC. Among the first group, the end-expiratory occlusion test (EEOT) and the lung recruitment maneuver (LRM) have been previously successfully tested in surgical patients. The EEOT consists of the interruption of the mechanical ventilation for 30 seconds, whereas the LRM consists in the increase in the peak inspiratory pressure up to 30 cmH20 for 30 seconds and in the assessment of the changes in the SV after the maneuvers. These tests are safe and can be easily applicable during the surgery to predict fluid responsiveness and optimize the fluid therapy. The primary aim of the present study is to compare the reliability of EEOT and LRM in predicting fluid responsiveness in patients undergoing general surgery.
Bioimpedance is recently known to be a reliable, reproducible and validated technic allowing determination of hydratation status in patients with chronic kidney disease treated with peritoneal dialysis (PD). Overhydratation attested by bioimpedance is strongly associated with cardio-vascular morbidity and mortality in patients with PD. Overhydratation might concern more than half of patients at PD initiation, though the underlying mechanism remains unknown. High peritoneal permeability (HPP) might concern about a third of patients starting a PD, although only a few datas are published on this condition. HPP at initiation of PD is associated with a decrease in both technical and patient survival and might be responsible of ultrafiltration failure. The underlying mechanisms of HPP at initiation of PD also remains unknown. To our knowledge, the correlation between hydratation status and peritoneal permeability at initiation of peritoneal dialysis remains unknown. Moreover, there is no datas concerning the cinetic evolution of peritoneal permeability; demographic or biologic factors associated with HPP in days and months following PD start. The aim of the present study is to correlate hydratation status (attested by bioimpedance) and peritoneal permeability at early start of peritoneal dialysis. Thus, we investigated early cinetic of peritoneal permeability at different time point during the first year of peritoneal dialysis and we analyzed the demographical and biological factors associated with HPP and overhydratation during this period. This study is a prospective, multicentric cohort study. Fourty patients recruited in a two years' period in five centers of nephrology will be included. Hydratation status will be determined with Fluid Overload measurement by bioimpedance technic thanks to BCM system (Fresenius Medical Care®). Peritoneal permeability will be determined by modified Peritoneal Equilibration Test with complete drainage at sixty minutes. Datas will prospectively be collected, including: weight, blood pressure, diuretic posology, diuresis, PD modality, dialysate prescribed.
