Filter by:The purpose of this study aimed to compare the efficacy of Oxiris (Baxter) and M100 filters on IL-6 as primary outcomes and other blood cell counts, blood biochemistry (serum urea, creatinine, potassium, sodium), inflammation indicators (CRP, PCT), as secondary outcomes and safety (28 days mortality as a primary outcome and coagulopathy, lifespan of filter, usage of vasopressor, clinical conditions (ventilator-free days, ICU and hospital- length of stay) as a secondary outcome), clinical conditions (ventilator-free days, ICU and hospital- length of stay), and mortality of patients with pneumonia-related AKI.
Laparoscopic and minimally-invasive robotic access has transformed the delivery of urological surgery. While associated with numerous desirable outcomes including shorter post-operative stay and faster return to preoperative function, these techniques have also been associated with morbidity such as reduced renal blood flow and post-operative renal dysfunction. The mechanisms leading to these renal effects complex are multifactorial, and have not been fully elucidated. However they are likely to include direct effects from raised intra-abdominal pressure, and indirect effects secondary to carbon dioxide absorption, neuroendocrine factors and tissue damage from oxidative stress. It is well documented that pneumoperitoneum places profound stress on the cardiovascular, respiratory and gastrointestinal systems; it also places strain on the renal system. During robotic surgery, continuous pneumoperitoneum and continuous rising of intra-abdominal pressure causes transient oliguria. Moreover, kidney function, estimated by the GFR, deteriorates during elevated intra abdominal pressure (IAP), and most of the studies identified decrease in renal blood flow (RBF) and renal cortical perfusion. Studies conducted to assess the contribution of the nitric oxide (NO) system to the renal hemodynamic/function alterations during pneumoperitoneum, concluded that these adverse effects are probably related to interference with the NO system, and could be partially ameliorated by pretreatment with nitroglycerine. Mannitol is an osmotic diuretic and a renal vasodilator that promotes tubular flow, prevents intratubular cast formation, decreases postischemic cellular swelling, and might serve as a free radical scavenger. Mannitol has traditionally been administered before renal surgeries to minimize perioperative renal dysfunction according to preclinical animal studies and clinical experience with renal transplantation. However, high-level clinical data in support of this belief are not available. The aim of this study is to characterize the effects of increased intra-abdominal pressure on renal perfusion and function in cases undergoing robotic lower tract urologic surgeries, and to assess the contribution of either mannitol or nitroglycerin infusion to the renal hemodynamic/function alterations during pneumoperitoneum.
To study the ability of RRI, measured by bedside Doppler ultrasound, in detecting acute kidney injury in high-risk patients admitted to surgical intensive care unit, Aswan university hospital, compared with renal biomarkers and conventional assessment using urine output and serum creatinine levels.
This is a prospective randomized clinical trial designed to determine the effect of intraoperative dexmedetomidine administration on renal function after coronary artery bypass graft surgery.
Approximately 150 patients with acute kidney injury (AKI) associated with acute hypoxemic respiratory failure (AHRF) will be randomized at up to 40 sites. Patients will be randomly assigned to either Auxora or matching placebo. Study drug infusions will occur every 24 hours for five consecutive days for a total of five infusions.
In our locality, limited studies have discussed AKI in patients with liver cirrhosis and its outcome, therefore we aim to highlight the incidence, patterns, risk factors, and outcomes of acute kidney injury in patients with liver cirrhosis at Sohag University Hospital.
Shock state is defined as an acute, life-threatening, circulatory failure with impaired tissue oxygenation (or tissue hypoxia). The cause of the shock state can be septic, anaphylactic, hypovolemic or cardiogenic. Its management is based on etiological treatment and replacement of organ failures. Acute kidney injury (AKI) may be lead by renal hypoxia. Acute kidney injury is frequent in patients admitted to intensive care unit (ICU) and associated with an increased mortality. Serum creatinine is the reference biological marker in the diagnosis of Acute kidney injury. However, its use is limited by a delayed increase in plasma creatinine level in relation to the causal renal agression, at a time when renal tissue damage may already be established. Thus, the identification of a biological marker making it possible to estimate renal hypoxia continuously during a shock could allow us to identify early a situation at risk of evolving into Acute kidney injury. The renal medulla is vulnerable to tissue hypoxia with a risk of acute tubular necrosis. As in situ measurement of mPO2 is not possible in current practice in humans, several studies have shown a positive correlation between variations in mPO2/uPO2 and occurence of Acute kidney injury. In humans, studies have shown a significant association between the reduction in uPO2 in cardiac surgeries and the occurrence of postoperative Acute kidney injury. The aim of the study is to describe the association between uPO2 values and the onset of Acute kidney injury and/or the ocurrence of early recovery of renal function after Acute kidney injury. Any patient in shock (group A) or without shock and requiring urinary catheterization as part of treatment (group B) admitted to the Medical-Intensive Care Unit of Angers University Hospital is eligible for inclusion. After inclusion, a continuous uPO2 measuring probe is introduced with the placement of the urinary probe. uPO2 is collected continuously for the first 5 days of admission or until discharge from intensive care or removal of the urinary catheter. uPO2 is also measured by a gasometry on a urine sample on a multi-daily basis. Serum creatinine is collected every 12 hours (twice a day) and diuresis every two hours for 5 days.
Prospective observational cohort study; pediatric sepsis vs. healthy pediatric subjects and pediatric sepsis with acute kidney injury (AKI) vs without AKI. Blood samples and renal ultrasound will be collected on sequential days for septic subject and one time for the healthy patients. Enzyme-linked immunosorbent assays (ELISA) with be run on serum plasma to compare the renin-angiotensin-aldosterone system (RAAS) between groups.
To evaluate the efficacy and safety of phentolamine in prevention of CA-AKI following complex PCI in patients at high risk of CA-AKI.
This project investigates intentionally hypotensive management such as NTG (nitroglycerin) or NTG+Trandate during general anesthesia in patients undergoing orthognathic surgery. Throughout the entire surgical procedure, blood biochemical and urine monitoring will be conducted. Serum creatinine (Cr) levels, urine analysis, and perioperative monitoring will be utilized as indicators for assessing renal function during the surgery. The objective is to assess its potential renal injury and identify early risk factors for acute kidney injury (AKI). Timely recognition of these factors will allow for the implementation of appropriate intervention strategies, aiding in the prevention of postoperative acute kidney injury. This approach contributes to achieving the goals of Enhanced Recovery After Surgery (ERAS) for surgical patients, promoting faster postoperative recovery.
