Filter by:The use of echocardiography in intensive care is a developing field. In expert hands echocardiography has proven its utility in diagnosing cardiac pathology, differentiating shock states and in haemodynamic monitoring. However, whether the results obtained by experts can be generalized to trainees or specialists with limited training remains unclear. Further, concerns around training time and cost for intensive care staff have been a factor in limiting the uptake of echocardiography in intensive care. The investigators aim to assess the diagnostic accuracy of Australian ICU doctors in training after completion of the current minimum training. After completing a structured teaching program and 30 mentored training scans trainees will be assessed on their accuracy with echocardiography. In the research phase trainees will complete a further 40 scans with each one matched with an expect scan. The results from the expert and trainee scans will be compared to determine the trainee's accuracy.
The purpose of this study is to evaluate predictability of a respiratory variation in pulse oximeter plethysmography for fluid responsiveness in children undergoing major surgery.
In this study the impact of two CE marked and FDA approved sternal needles in comparison to intravenous access on the flow-rate of autologous reinfusion of whole blood and the possible hemolysis of red cells post-transfusion in a population of healthy military officers is investigated.
The purpose of this study is to determine if extra systoles can be used to predict fluid responsiveness perioperatively in patients undergoing on pump coronary artery bypass graft (CABG) surgery. As an additional study we will investigate the ability of a mini fluid challenge to predict response of a larger volume of fluid.
The aim of the study is to identify the diagnostic value of the focused assessed echocardiography in septic patients undergoing urgent abdominal surgery due to peritonitis. The investigators expect that the incidence of hemodynamic instability will be reduced and the survival of the patients will be improved.
Study Design: Prospective observational study Study Location: Liverpool Hospital Intensive Care Unit, South Western Sydney Local Health District, Sydney, Australia. Target study size: 100 patients Ethics: Approved by the local Human Research and Ethics Council (HREC) at Liverpool Hospital (LPOOL) as a Low Negligible Risk (LNR) project [HREC/LNR/14/LPOOL/295, HREC/LNR/15/LPOOL47, HREC/LNR/14/LPOOL/150] Participants: Post cardiac surgical patients admitted to the Intensive Care Unit between March-October 2016 Aims: 1. to determine the descriptive and predictive value of variables (outlined below) related to oxygen delivery/consumption in regards to the effects of intravascular volume expansion 2. to assess correlations between central and peripheral variables (outlined below) relevant to oxygen delivery/consumption 3. to assess correlations between a set of variables (outline below) and patient centred outcomes in ICU and in hospital Main variables collected: 1. Tissue oxygen saturation by peripheral Near-Infrared Spectroscopy (NIRS) 2. Common carotid arterial Doppler 3. Arterial/mixed venous/central venous blood gas analyses 4. Haemodynamic parameters 5. Organ support measures Data collection time points: 1. ICU admission (within 30 minutes) 2. Before administration of a fluid bolus 3. After administration of a fluid bolus 4. 6 hours after ICU admission 5. Morning of first postoperative day (12-24 hours) Outcome measures: 1. the response to intravascular volume expansion 2. ICU mortality, morbidity and length of stay and hospital mortality and length of stay Data analysis: 1. Clinical data are collected bedside using an electronic case record form 2. Descriptive statistics 3. Paired and unpaired comparative 4. Correlative and predictive statistics
The purpose of this study is to evaluate predictability of an abdominal compression-induced change of blood pressure for fluid responsiveness in children with single ventricle (bidirectional cavopulmonary shunt and Fontan tract).
The investigators would like to study cardiac output, stroke volume, and fluid responsiveness on young adult pediatric patients undergoing anesthesia and surgery with the use of the NICOM, a non-invasive monitor. The NICOM method is non-invasive and provides reliable trending of cardiac output and stroke volume. Measuring cardiac output in conjunction with routine monitoring will provide a better assessment of intra-operative status.
It is the objective of the study to investigate the efficacy and safety of two different volume replacement regimens with gelatine solutions.
This study is a phase III, randomized, controled, parallel groups, single blinded, clinical trial that aims at comparing the improvement of right ventricular function after administration of a hypertonic solution versus Ringer Lactate following cardiac surgery. Adults patients admitted to Grenoble University Hospital for elective cardiac surgery under cardiopulmonary bypass, in sinus rhythm and with Swan Ganz monitoring will be included. Patients needing fluid expansion in the first three hours after surgery will be randomized in two groups : one receiving Ringer Lactate (10 mL/kg), the other receiving hypertonic saline solution (3 mL/kg). Right ventricular function measured with Swan Ganz catheter, 30 minutes after fluid expansion will be the primary outcome.
