Filter by:Hemodynamic management of critically ill patients has long been focused on the arterial side of the vasculature by assessing adequate perfusion pressure. However, the venous pressure is also of critical importance. Venous congestion can occur in patients with right ventricular failure, pulmonary hypertension or fluid overload. Fluid overload has harmful effects to end organs causing acute kidney injury (AKI), lung edema, multiorgan dysfunction and death. Vice versa, AKI can aggravate fluid retention and inflammation. The measurement of venous pressure usually relies on central venous pressure (CVP) and inferior vena cava diameter (IVC). However, CVP measurement has been associated with measurement errors and has low accuracy in predicting fluid responsiveness. Moreover, IVC collapsibility or distensibility is a static parameter and is associated with subjective variability. Multiorgan Point-of-Care ultrasound (POCUS) can enhance the management of AKI by enabling the evaluation of renal structural abnormalities and hemodynamic status . POCUS allows the clinician to assess intravascular and pulmonary fluid overload. It has been shown that POCUS is a good parameter to predict global fluid status of the patient . Venous Excess Ultrasound (VEXUS) consists of the evaluation of IVC, hepatic vein, portal vein and intrarenal vein flow pattern. Previous studies showed significant correlation between VExUS score with RRT-free days and guide fluid management in critically ill patients with AKI . VExUS is useful in predicting patients at risk to develop AKI post cardiac surgery . Adding modified lung ultrasound score to the VExUS protocol could help clinician to adjust fluid administration and achieve proper fluid balance during continuous kidney replacement therapy (CKRT). However, the role of using combined VExUS and lung ultrasound in the assessment and guidance of fluid management during CKRT is unknown.
Assessment of the effect of gabapentin as an analgesic replacement on the Kidney function following Laparoscopic sleeve gastrectomy for Morbid Obese Patients by measuring two biomarkers: NGAL (Neutrophil gelatinase-associated lipocalin)and DKK3 (Dickkopf-3)
Acute kidney injury is a common complication in critically ill patients. This condition can significantly prolong the length of hospital stay, increase the cost of hospitalization, and have a high mortality rate and a poor prognosis. Early assessment of patients' prognosis with acute kidney injury is vital for clinical treatment. Point-of-care ultrasound and renal injury biomarkers can be used to evaluate kidney injury at different levels. Therefore, it is speculated that dynamic monitoring can accurately predict the prognosis of patients with kidney injury.
The multiFiltratePRO is a device for extracorporeal blood purification treatments. In this retrospective analysis, the treatments of patients who received at least one treatment with the investigational device as mentioned between January 2015 and January 2024 will be documented in a chronological order. No further control treatments will be investigated in this one-arm design. The design is considered to be appropriate to reflect daily clinical practice and to contribute to empirical evidence of performance of the multiFiltratePRO system.
Acute kidney injury (AKI) is a common complication of septic shock and together these conditions carry a high mortality risk. In septic patients who develop severe AKI renal cortical perfusion is deficient despite normal macrovascular organ blood flow. This intra-renal perfusion abnormality may be amenable to pharmacological manipulation, which may offer mechanistic insight into the pathophysiology of septic AKI. The aim of the current study is to investigate the effects of vasopressin and angiotensin II on renal microcirculatory perfusion in a cohort of patients with septic shock.
Data on the optimal period for RRT weaning in critically ill patient are scarce. The current practice for RRT weaning is based on urine output, the threshold of which is debatable. Two recent observational studies have shown that an increase in urinary creatinine or urea concentrations is a better predictive marker of RRT weaning than urine output. An unjustified delay in RRT weaning leads to numerous complications such as catheter-related infections, delay of the patient's functional recovery, severe ionic disorder, bleeding, and induced hemodynamic instability. It also induces an increase workload for careers and in cost without any additional benefit for the patient. Conversely, too early weaning inevitably limits the prevention on fluid accumulation that is independently associated with an increased risk of mortality and inevitably leads to resumption of RRT requiring reinsertion of dialysis catheter resulting in potential complications. A multicentre randomized controlled trial will be then necessary and only able to identify the optimal RRT weaning strategy. The main objective is to compare two RRT weaning strategies on RRT duration in critically ill patients with acute kidney injury: a strategy based on combined criteria (urine output + urinary parameters) as compared to a single strategy based only on urine output. The study protocol will be an open-label, two parallel group, multicenter, randomized, controlled clinical trial, in which enrolled ICU adult patients will have RRT weaning based either on urine output alone (single strategy) or on urine output and urinary parameters (combined strategy). When the urine output is greater than 500ml/24h, the enrollment must be performed within 24hours in 2 groups:. " Single strategy ": In the single strategy, RRT weaning will be achieved when urine output exceeds 500ml/24h without diuretics or 2000ml/24h with diuretics use. " Combined strategy": In the combined strategy, when urine output exceeds 500ml/day with or without diuretic use, RRT will be stopped during 48h to assess urinary indices (urinary creatinine and urea). Soon as urinary indices are higher than thresholds values (urinary creatinine > 5.2mmol/day and urinary urea > 1.35mmol/kg/day, RRT will be weaned. If they are lower, a RRT session will be perform after which the weaning process will be resume. The primary endpoint is the number of RRT-free days at D30 with at least 7 consecutive days alive and without RRT.
To detect frequency of acute kidney injury in critically ill children in Assuit university hospital. To detect associated AKI risk factors, severity and outcomes . To assess the value of use of renal Doppler ultrasound in AKI.
The research design is a prospective, randomized, controlled clinical trial in children to study effect of aminophylline in preserving renal function in oncologic patient received cisplatin either combined with other CMT or used alone. The participants in both groups will receive standard protocol pre-cisplatin infusion which include hydration with 5%DNSS/2 with KCL and MgSO4 IV infusion. In the treatment group, the participants will receive aminophylline infusion in the first 24 hours along with cisplatin, followed by oral aminophylline oral three times daily orally for 4 consecutive days post cisplatin. The aminophylline serum level will be maintained at the therapeutic range 10-20 mg. The side effect of aminophylline including nausea, vomiting and ECG will be monitored. The collected data including urine volume, GFR (estimated by cystatin C-creatinine based equation and by radiopharmaceutical-Tc DTPA), and renal tubular biomarker (urine B2 macroglobulin and urine NGAL) will be collected at baseline before receiving cisplatin, 24 hours and 5 days post cisplatin.
Urinary Activin A as amarker for assessement of acute kidney injury severity in patient admitted at Assuit University Hospital
Patients who are very ill either due to a severe infection, major organ injury, trauma or a major operation may require significant support with devices such as a dialysis machine for the kidneys or Extracorporeal Membrane Oxygenation (ECMO) for the heart and lungs. This is often due to a reaction of the body to the insult which is termed inflammation. The investigators would like to assess if the use of a device that can remove the agents driving this reaction can lead to a quicker recovery form the illness. The device is a blood filter called HA380 and it would be connected to either the dialysis machine or the ECMO circuit. The investigators want to assess the feasibility of conducting a study with the HA380 column. We will also evaluate if the use of the HA380 column has an effect on the time spent on dialysis or ECMO, time spent on the breathing machine, time spent requiring drugs to support blood pressure and time spent in the intensive care unit.
