Description
Intensive care management of liver transplanted patients involves close monitoring in the immediate postoperative period to address potential complications and ensure graft function.
Careful assessment of vital signs, fluid balance, and laboratory parameters is crucial to detect early signs of complications such as graft rejection or infection. Immunosuppressive medications are administered to prevent organ rejection, and their dosages are meticulously adjusted based on therapeutic drug monitoring. Maintaining hemodynamic stability is paramount, as fluctuations in blood pressure and perfusion can impact graft function and patient outcomes. Continuous monitoring of liver function tests, coagulation parameters, and renal function helps in early identification and management of potential complications.
Infection prevention strategies, including prophylactic antibiotics and vigilant monitoring for signs of infection, are integral to post-transplant care. Nutritional support is essential to promote healing and support the metabolic demands of the post-transplant recovery process.
Regular imaging studies, such as Doppler ultrasound, aid in assessing blood flow to the transplanted liver and identifying potential vascular complications. Multidisciplinary collaboration between transplant surgeons, intensivists, hepatologists, and nursing staff is crucial for comprehensive and effective post-transplant care. Patient education regarding medication adherence, signs of complications, and the importance of follow-up care plays a significant role in the long-term success of liver transplantation.
Résumé
- The presentation covers intensive care management of liver transplant recipients, focusing on critical care rather than donor aspects. It outlines the three phases of liver transplant: pre-anhepatic (dissection), anhepatic (vascular exclusion), and neo-hepatic (reperfusion). Key terms like cold ischemia time, warm ischemia time, and IVC clamp time are explained, highlighting their implications. Complications are classified into medical (hemodynamic, renal, neurological) and surgical (hemorrhage, vascular problems, biliary issues).
- Graft dysfunction is divided into primary non-function, initial poor function, delayed graft function, acute cellular rejection, and recurrent viral hepatitis. The lecture defines primary non-function as requiring immediate re-transplantation and details early graft dysfunction based on enzyme levels. It touches on the Small for Size Syndrome, a factor considered for living donor liver transplants, and vascular complications like hepatic artery thrombosis and portal vein thrombosis, stressing the use of Doppler and CT angiography for diagnosis.
- Hemodynamic and fluid management are vital, noting the difficulty in assessing hemodynamics in CLD patients who are often vasodilated and fluid-overloaded. It highlights the importance of maintaining euvolemia, avoiding both hypovolemia and hypervolemia. Electrolyte imbalances like hyponatremia, hypo/hyperkalemia, and hypocalcemia are discussed, along with the importance of glycemic control given the liver's role in carbohydrate metabolism and the use of immunosuppressants like steroids.
- Renal issues are frequently seen, often due to pre-existing conditions, fluid overload, or medication side effects. Neurological complications, ranging from seizures to cerebrovascular events, require careful monitoring and prompt treatment. Infections are cited as the most common cause of death in liver transplant recipients, emphasizing early administration of effective empirical antibiotics.
- Nutritional support is crucial, addressing protein energy malnutrition and sarcopenia by providing high-protein, high-energy diets. Immunosuppressants are classified into non-selective (corticosteroids, anti-metabolites) and selective (calcineurin inhibitors, mTOR inhibitors), noting their side effects. Finally, respiratory issues, including hepatopulmonary syndrome, are discussed, underscoring the importance of early extubation when possible.
