Epidural Anesthesia? No of Course

Although the contraindications for thoracic epidural anesthesia (TEA) are well defined, the debate continues about whether TEA improves outcomes. Pro and con trials and a metaanalysis in the past have yielded equivocal results; they did not deal with new vascular intervention or drugs. The benefit of TEA in surgery is to provide analgesia. In subgroups, TEA can decrease the mortality and morbidity. In contrast, the cost can increase in the situation of a complication that is opposite to the side effects is rare, but the impairment caused by them is out of proportion to the benefits. Primary or secondary prophylaxis with antithrombotic drugs is increasing in developed countries because of the increasing cardiovascular interventions and aging of the population. The neuroaxial guidelines are useful, but the changing of the coagulation profile after hepatectomy is not included in them. The decision to use TEA in liver surgery must be individualized with steps planned from the beginning. TEA suitability is based on an evaluation of the contraindications, comorbidities, coagulation profiles, hepatic reserve, and balance of benefits and risks. The insertion or withdrawal of the epidural catheter should be made with care according to the neuroaxial guidelines and in the presence of a normal TEG. The decreasing level of prothrombin content and platelet counts after hepatectomy should be closely monitored every 2 to 5 days.

The attitude and knowledge of intensive care physicians and nurses regarding organ donation in Hungary--it needs to be changed.

BACKGROUND The education of intensive care professionals can influence the number of transplantable organs. The aim of this cross-sectional study is to estimate the attitude and knowledge of intensive care staff as about organ donation. MATERIAL/METHODS The self-completed questionnaire was completed at the Congress of the Hungarian Society of Anesthesiology and Intensive Therapy in 2011. Data, including attitudes about donation, attendance in an organ donation course, donation activity, self-reported knowledge of donor management, legislation, transplantation, and aftercare were collected from intensive care specialists (n=179) and nurses (n=103). RESULTS An organ donation course was attended by 53.6% of physicians and 16.7% of nurses (p=0.000); the 59% of doctors and 64.7% of nurses who did not participate in education were not willing to do so. Older staff were more likely to attend the course (p<0.01). Organ donation activity was not influenced by age or type of staff (physician or nurse), but it was higher among staff who attended training (p<0.01). Independently from accepting the presumed consent legislation (91.1%), 66% of intensive care professionals supported the practice of requesting the consent of family for organ retrieval. Self-reported knowledge regarding the Eurotransplant, donor management, the law and ethics of donation, transplantation, and after care for transplanted patients was influenced by age, donation activity, education, type of staff (p<0.01). CONCLUSIONS Education, including knowledge concerning brain death, donor management and communication with family, needs to be part of the specialist training of intensive care professionals, with a refresher course every fifth year.

Volumetric Hemodynamic Changes and Postoperative Complications in Hypothermic Liver Transplanted Patients

INTRODUCTION Hepatic diseases decrease the livers involvement in thermoregulation. Removal of the liver during transplantation increases the incidence of hypothermia during the surgery. The aims of the present study were to analyze the hemodynamic changes among hypothermic liver transplantations and to determine its relationship to postoperative complications. METHODS Conventional and volumetric hemodynamic monitoring and intramucosal pH measurements were performed during 54 liver transplantations. According to the core temperature until graft reperfusion, patients were classified into group A, hypothermic patients (temperature < 35 °C; n=25) versus group B, normothermic patients (temperature > 36 °C; n=29). We examined the relationships between central venous pressure (CVP), intrathoracic blood volume index, cardiac index (CI), and oxygen delivery index, oxygen consumption index, as well as the fluctuation of the mean arterial pressure (MAP) and gastric intramucosal pH and activated clotting time. We recorded prolonged ventilation time, vasopressor and hemodialysis requirements, occurrence of infections, and intensive care days. RESULTS There were no significant differences in the MELD scores. More Child-Pugh class C patients (P<.01) showed significantly higher APACHE II scores (P<.02) among group A. During hepatectomy and at the same intrathoracic blood volumes, the hypothermic group showed significantly higher CVP levels (P<.02). During the anhepatic and postreperfusion phases, the decreased CI levels (P<.05) were associated with increased MAP values (P<.05). Without differences in oxygen delivery, the oxygen consumption was lower in group A (P<.05). The intramucosal pH levels were the same in the both groups during the whole examination period. More instances of infection, intensive care, and hemodialysis treatment days, were observed as well as significantly longer vasopressor requirements and coagulopathy among the hypothermic group (P<.007).

MARS therapy, the bridging to liver retransplantation — Three cases from the Hungarian liver transplant program

Besides orthotopic liver transplantation (OLT) there is no long-term and effective replacement therapy for severe liver failure. Artificial extracorporeal liver supply devices are able to reduce blood toxin levels, but do not replace any synthetic function of the liver. Molecular adsorbent recirculating system (MARS) is one of the methods that can be used to treat fulminant acute liver failure (ALF) or acute on chronic liver failure (AoCLF). The primary non-function (PNF) of the newly transplanted liver manifests in the clinical settings exactly like acute liver failure. MARS treatment can reduce the severity of complications by eliminating blood toxins, so that it can help hepatic encephalopathy (HE), hepatorenal syndrome (HRS), and the high rate mortality of cerebral herniation. This might serve as a bridging therapy before orthotopic liver retransplantation (reOLT). Three patients after a first liver transplantation became candidate for urgent MARS treatment as a bridging solution prior to reOLT in our center. Authors report these three cases, fo-cusing on indications, MARS sessions, clinical courses, and final outcomes.

Role of Early Systemic Inflammatory Response in Simultaneous Pancreas-Kidney Transplantation

Pancreas grafts are susceptible to surgical complications mostly related to exocrine secretions and the low microcirculatory blood flow through the gland. During simultaneous kidney-pancreas transplantation, the systemic response depends on reperfusion of two organs acute graft pancreatitis, immunotherapy, coagulopathy, bleeding, and other factors. We performed a retrospective review of 10 adult simultaneous pancreas-kidney transplant patients to evaluate progression of early postoperative inflammation in the absence of infection. All patients were treated with four-drug therapy. We performed analyses of procalcitonin (PCT), C-reactive protein, serum creatinine, amylase, and lipase levels over the first 5 postoperative days. Relatively high peak PCT levels (maximum 130 ng/mL) were reached within 24 to 48 hours postoperatively followed by a moderate decrease. Consistent with this observation, the serum creatinine, amylase, and lipase levels decreased continuously to normal concentrations within the first week. The increased PCT levels seemed depend upon the surgical procedure and intraoperative events. PCT was superior to C-reactive protein to discriminate infection from inflammation in this setting. The dynamics of PCT levels, rather than absolute values, seemed to be important. Lack of a decrease in PCT levels after the peak, suggested an infectious complication or the development of sepsis. Monitoring and assessment of PCT levels may help in early recognition of infection and institution of therapy.

West Nile virus encephalitis in kidney transplanted patient, first case in Hungary: Case report

Abstract The complications caused by the rarely viral infections are more frequently treated in ICU (intensive care unit). The world paid attention to the WNV (West Nile virus) infections only in 1999, when 62 meningoencephalitis were registered in New York State. Six cases of WNV occur annually in Hungary. The authors present the first transplanted Hungarian patient with WNV encephalitis. The patient was hospitalized with epigastric pain, diarrhea, continuous fever, and decreasing amount of urine. The first checkup of infectious diseases was without any result. Although using of empirical antimicrobal therapy, the multiorgan failure patient remained febrile. On the basis of clinical signs, meningitis or encephalitis was suspected despite negative results of repeated cultures. On the 8th day, WNV infection was confirmed by serological examinations. With intravenous immunoglobulin therapy used within confines of supportive treatment, the patient became afebrile. After 21 days in ICU with good graft functio...

Magyarországi intenzív osztályok szervdonációval kapcsolatos személyi és tárgyi feltételei

INTRODUCTION At the end of 2016, the number of patients on the domestic transplant waiting list was twice as much as the number of the organ transplantations accomplished that year. The institutional prerequisites for functional organ donation programs are the sufficient number of personnel and the adequate material conditions to be provided in relation to the needs. AIM The goal of the current study was to evaluate the professional environment in Hungary. METHOD The Organ Coordination Office at the Hungarian National Blood Transfusion Service compiled a questionnaire survey on the personnel and material conditions of the intensive care units (ICUs) in Hungary in regards to organ donations. The survey applied an online questionnaire including 43 questions. In addition to the number of beds and employees, we investigated the tools needed for the legal and the medical diagnosis of brain death as well as the accessibility of examinations on the donor information form. The data collection spanned from 12 December 2016 to 30 June 2017. RESULTS 59 intensive care units completed the questionnaire; the investigation involved 640 hospital beds, 816 physicians and 1252 nurses. In the daytime shift, 0.25 doctors and 0.41 nurses work on a patient bed at an average, while in the night shift, the figures are 0.11 and 0.33, respectively. 51.7% of the doctors are registered to access the National Non-Donor Registry, and brain death diagnosis committee is available in 83% of the hospitals. Among the medical imaging methods (cranial, abdominal-thoracic), CT scan in 71-73%, abdominal ultrasound in 75%, transthoracic echocardiograpy (TTE) in 37%, transoesophageal echocardiography (TEE) in 4%, bronchoscopy in 49%, coronarography in 19% are non-stop available, with instant interpretation in 75% of the cases. Transcranial Doppler (TCD) in 30%, four-vessel angiography in 45% and SPECT in 14% of the cases are available. More than 90% of the laboratory examinations on the donor information form are available 24 hours a day. CONCLUSION The number of doctors and nurses did not change compared to our 2008 survey (0.18 doctors, 0.37 nurses/ICU beds in 2008), but the care of potential donors needs more resources and time. The standby availability of personnel and material conditions is a prerequisite for organ donation programs in order to save lives. Orv Hetil. 2018; 159(33): 1360-1367.
