Anesthesia acidosis kidney transplant

BACKGROUND: International guidelines have recommended preemptive kidney transplantation (KT) as the preferred approach, advocating for transplantation before the initiation of dialysis. This approach is advantageous for graft and patient survival by avoiding dialysis-related complications. However, recipients of preemptive KT may undergo anesthesia without the opportunity to optimize volume status or correct metabolic disturbances associated with end-stage renal disease. In these regard, we aimed to investigate the anesthetic events that occur more frequently during preemptive KT compared to nonpreemptive KT...

BACKGROUND: Transplant candidates on the waiting list are increasingly challenged by the lack of organs. Most of the organs can only be kept viable within very limited timeframes (e.g., mere 4-6 h for heart and lungs exposed to refrigeration temperatures ex vivo). Donation after circulatory death (DCD) using extracorporeal membrane oxygenation (ECMO) can significantly enlarge the donor pool, organ yield per donor, and shelf life. Nevertheless, clinical attempts to recover organs for transplantation after uncontrolled DCD are extremely complex and hardly reproducible...

BACKGROUND: Transfusion rates in cardiac surgery are high. AIM: To determine if intraoperative autologous blood removal without volume replacement is associated with fewer homologous blood transfusions without increasing acute kidney injury. SETTING AND DESIGN: Retrospective, comparative study. MATERIALS AND METHODS: Adult patients undergoing cardiac surgery, excluding those who underwent ventricular assist device surgery, heart transplants, or cardiac surgery without cardiopulmonary bypass were excluded, who had 1-3 units of intraoperative autologous blood removal were compared to patients without blood removal for determination of volume replacement, vasopressor support, acute kidney injury, and transfusions...

Background and Aims: Intraoperative fluid management is important in renal transplant recipients with end-stage renal disease. Conventionally, central venous pressure (CVP) has been used to guide perioperative fluid administration but with high incidence of poor graft outcome. There is a requirement of reliable parameter to guide the fluid therapy in these patients so as to minimize the perioperative complications and improve the outcome. Hence, this study was conducted. Material and Methods: This prospective study included 75 patients of chronic kidney disease undergoing renal transplantation...

BACKGROUND: Generally, lactate levels > 2 mmol/L represent hyperlactatemia, whereas lactic acidosis is often defined as lactate > 4 mmol/L. Although hyperlactatemia is common finding in liver transplant (LT) candidates, association between lactate and organ failures with Acute-on-chronic Liver Failure (ACLF) is poorly studied. We searched the important variables for pre-LT hyperlactatemia and examined the impact of preoperative hyperlactatemia on early mortality after LT. METHODS: A total of 2,002 patients from LT registry between January 2008 and February 2019 were analyzed...

BACKGROUND: Intraoperative fluid management may affect the outcome after kidney transplantation. However, the amount and type of fluid administered, and monitoring techniques vary greatly between institutions and there are limited prospective randomized trials and meta-analyses to guide fluid management in kidney transplant recipients. METHODS: Members of the American Society of Anesthesiologists (ASA) committee on transplantation reviewed the current literature on the amount and type of fluids (albumin, starches, 0...

BACKGROUND: Recent studies have shown a decline in glomerular filtration rate and increased renal vasoconstriction after administration of normal saline when compared with IV solutions with less chloride. In this study, we investigated the impact of normal saline versus a chloride-reduced, acetate-buffered crystalloid on the incidence of hyperkalemia during cadaveric renal transplantation. The incidence of metabolic acidosis and kidney function were secondary aims. METHODS: In this prospective randomized controlled trial, 150 patients received normal saline or an acetate-buffered balanced crystalloid during and after cadaveric renal transplantation...

BACKGROUND: Ischemia-reperfusion injury is an inevitable consequence of kidney transplantation, leading to metabolic acidosis. This study compared the effects of normal saline (NS) and Plasmalyte on acid-base balance and electrolytes during living donor kidney transplantation using the Stewart and base excess (BE) methods. METHODS: Patients were randomized to an NS group (n = 30) or a Plasmalyte group (n = 30). Arterial blood samples were collected for acid-base analysis after induction of anesthesia (T0), prior to clamping the iliac vein (T1), 10 minutes after reperfusion of the donated kidney (T2), and at the end of surgery (T3)...

We report a case of hyperkalemia in a recipient of living-related liver transplantation. The patient received a continuous infusion of gabexate mesilate at 60 mg x hr(-1) starting about 1 hr after the induction of anesthesia. The serum potassium concentration (K+) was increased from 4.53 mEq x l-(1) to 5.08 mEq x l(-1) within about 1 hr. Thereafter, a massive blood loss caused by an accidental damage of the portal vein necessitated rapid fluid therapy to maintain blood pressure. We observed an abnormal ECG recording including a wide QRS complex and a high T wave when about 30 units of leukocytes-reduced red cell concentrates had been transfused...

For many children with severe renal excretory dysfunction, renal transplantation is the sole method of life prolongation. The purpose of the investigation was to analyze the specific features of anesthetic maintenance of transplantation of related and cadaver kidney at 1 to 5 years. The investigation involved a detailed analysis of the specific features of 101 anesthesias made in children aged 1 to 16 years (mean 9.6+/-4.87 years) during transplantation of kidneys from corpses and apparently healthy relatives...

INTRODUCTION: Reperfusion is a crucial moment in kidney transplantation. Resumption of blood flow is associated with many metabolic changes, which result from the kidney's initial condition and preservation. These biochemical alterations including the acid-base balance are the part of ischemia-reperfusion injury. The study's purpose was to examine acid-base balance during the first 30 minutes after reperfusion of the transplanted kidney. MATERIALS AND METHODS: The 30 recipients (13 men, 17 women) averaged ages of 46 +/- 14 years...

A 15-year-old female with short intestine syndrome due to chronic intestinal pseudo-obstruction associated with kidney failure underwent a multivisceral (stomach-duodenum-jejunum-ileum-pancreas-liver) and kidney transplant. She had required parenteral nutrition for the last 5 years, with numerous complications such as sepsis from the central catheter, deep venous thrombosis, severe liver dysfunction, pancytopenia due to bone marrow failure, and severe malnutrition. Surgery lasted 15 hours and was free of complications other than hypothermia, which worsened after revascularization of the grafts...

Before the advent of curare, muscular relaxation essential for upper abdominal and intrathoracic surgery adequate operating conditions, could only be provided by deep ether or cyclopropane anaesthesia. The required depth of anaesthesia frequently caused severe cardiovascular depression, metabolic and respiratory acidosis and alteration of kidney and liver function. Ether, and especially cyclopropane sensitized the heart to the development of arrhythmias and the danger of explosion was never far away. For fear of anaesthetic mortality essential, life saving operations were often abandoned in poor risk patients...

Steps taken for intra-operative care and protection of the transplanted organ to aid its function recovery are explained.
