Propofol and Sevoflurane Anesthesia in Colorectal Cancer Surgery: Incidence of Acute Kidney Injury...

Acute Kidney InjuryCancer Colorectal

The goal of this observational study is to compare anesthetic modalities (intravenous propofol anesthesia with sevoflurane gas anesthesia) in patients who underwent colorectal cancer resection surgery regarding the outcome of acute kidney injury. The main questions it aims to answer are: is there a difference in acute kidney injury incidence in the two anesthetic modalities? is there a difference in plasma creatinine between the two anesthetic modalities? are there any patient characteristics or intraoperative factors that effect the incidence of acute kidney injury in either anesthetic modality? The study will analyze data from the CAN clinical trial database. (Cancer and Anesthesia: Survival After Radical Surgery - a Comparison Between Propofol or Sevoflurane Anesthesia, NCT01975064)

Acute Kidney Injury After Elective Total Joint Arthroplasty

Acute Kidney Injury

Total joint arthroplasty (TJA) is a common orthopedic procedure to treat patients with end-stage knee arthritis. Over 4,000 TJA were performed in the Hong Kong public hospitals in the past 12 months (July 2020 - June 2021) and the demand for this procedure is ever increasing with time. TJA are rehabilitative surgeries with an aim to accelerate patient ambulation and minimize hospital stay. To facilitate this process, multi-disciplinary enhanced recovery after surgery (ERAS) programs are implemented. This involves surgeons, anaesthetists, physiotherapists and nurses who follow an integrated care pathway to allow early patient mobilization and hospital discharge. The program reduces the hospital length of stay and this can reduce the risk of complications and mortality. One of the major challenges in TJA is postoperative pain. TJA is a very painful procedure with up to 50% of patients have moderate to severe pain (numeric rating scale >4) immediately after surgery. This can delay patient mobilization and hinder postoperative recovery. Severe postoperative pain is also associated with an increased risk of infection, myocardial ischaemia, respiratory complications and the development of chronic pain. Therefore, an effective multimodal analgesia is an essential component in the ERAS program. It combines different oral analgesics to limit opioid use and its related side effects. Celecoxib has been shown to reduce pain and opioid use after TJA. It is therefore recommended to be used routinely. However, its potential nephrotoxic property has led to its judicious use, especially in patients with preoperative chronic renal failure. Postoperative acute kidney injury (AKI) is an independent risk factor for mortality, cardiovascular complications and hospital length of stay6. However, the studies assessing the incidence of AKI following TJA are scarce, and with conflicting results. Therefore, the aim of our study is to retrospectively review the incidence and duration of AKI following elective TJA in a tertiary institution. We will evaluate the effect of celecoxib in our multimodal analgesia regimen on the risk of postoperative AKI and determine the risk factors associated.

Trial of Plasma Exchange for Severe Crescentic IgA Nephropathy

GlomerulonephritisIGA3 more

Crescentic IgA nephropathy (CreIgAN) has a poor prognosis despite aggressive immunosuppressive therapy. The efficacy of plasma exchange (PE) in CreIgAN is not well defined. This study will evaluate the efficacy and safety of plasma exchange as adjunctive therapy for severe crescentic IgA nephropathy compared to pulse methylprednisolone on a background of oral prednisolone and cyclophosphamide in prevent kidney failure.

Sodium Bicarbonate to Prevent Acute Kidney Injury in Children Undergoing Cardiac Surgery

Acute Kidney InjuryCongenital Heart Disease

The proposed study will investigate the effect of sodium bicarbonate on the prevention of acute kidney injury in children undergoing cardiac surgery with cardio-pulmonary bypass. The investigators hypothesize that the occurrence of acute kidney injury will be less in children treated with sodium bicarbonate in the perioperative period when compared to placebo. The specific aims of this proposal are as follows: 1. To institute a prospective, randomized, double-blinded, placebo-controlled trial in pediatric subjects undergoing cardiac surgery to determine the efficacy of sodium bicarbonate on prevention of acute kidney injury as measured by pRIFLE criteria. 2. To examine whether treatment with sodium bicarbonate modifies the duration of acute kidney injury, fluid balance, hospital length of stay, need for dialysis, and progression to kidney failure. 3. To determine the relevance of NGAL as a biomarker to predict development of acute kidney injury.

Bicarbonate in Cardiac Surgery

Acute Kidney Injury

With over one million operations a year, cardiac surgery with cardiopulmonary bypass is one of the most common major surgical procedures worldwide (1). Acute kidney injury is a common and serious postoperative complication of cardiopulmonary bypass and may affect 25% to 50% of patients (2-4). Acute kidney injury carries significant costs (4) and is independently associated with increased morbidity and mortality (2,3). Even minimal increments in plasma creatinine are associated with an increase in mortality (5,6). Multiple causes of cardiopulmonary bypass-associated acute kidney injury have been proposed, including ischemia-reperfusion, generation of reactive oxygen species, hemolysis and activation of inflammatory pathways (7-10). To date, no simple, safe and effective intervention to prevent cardiopulmonary bypass-associated acute kidney injury in a broad patient population has been found (11-14). Urinary acidity may enhance the generation and toxicity of reactive oxygen species induced by cardiopulmonary bypass (10,15). Activation of complement during cardiac surgery (16) may also participate in kidney injury. Urinary alkalinization may protect from kidney injury induced by oxidant substances, iron-mediated free radical pathways, complement activation and tubular hemoglobin cast formation (9,17,18). Of note, increasing urinary pH - in combination with N-acetylcysteine (19,20) or without (21) - has recently been reported to attenuate acute kidney injury in patients undergoing contrast-media infusion. In a pilot double-blind, randomized controlled trial the investigators found sodium bicarbonate to be efficacious, safe, inexpensive and easy to administer. These findings now need to be confirmed or refuted by further clinical investigations in other geographic and institutional settings. Accordingly, the investigators hypothesized that urinary alkalinization might protect kidney function in patients at increased risk of acute kidney injury undergoing cardiopulmonary bypass needs to be confirmed in an international multicenter, double-blind, randomized controlled trial of intravenous sodium bicarbonate.

High Cut-Off Continuous Veno-venous Hemodialysis (CVVHD) in Patients Treated for Acute Renal Failure...

Systemic Inflammatory Response SyndromeKidney Failure1 more

This study will assess the influence of the High Cut-Off (HCO) CVVHD treatment on the disease progression in septic patients. The primary aim of the study is to evaluate whether HCO CVVHD leads to a significant improvement of the hemodynamic status (mean arterial pressure, vasopressor requirements) in septic patients in comparison to CVVHD treatment with conventional high-flux filters. For the HCO-group the investigators expect a 50% lower dosage of vasopressors needed to maintain an adequate organ perfusion.
