Since 1984 the peritoneovenous shunt has been installed in 33 patients because of resistant ascites. The aim of this study was to find the optimal type of anesthesia in our conditions on our own clinical-patient material. All patients were classified by the ASA, Goldman, Child and Child-Puigh score. The patient, surgeon and anesthesiologist were polled about the quality of anesthesia, and all observed complications were followed, like after different premedications as well as in the course and after different types of neuroleptic anesthesia. General neuroleptic anesthesia was applied in 23 patients (69.7%), one was operated on in ketamine anesthesia (3.0%) and 9 (27.3%) in local anesthesia with 2% Xylocaine. After premedication with Thalamonal in all patients there came to a fall in arterial pressure for more than 20% of initial values and the feeling of uneasiness and fear was present. All patients with local anesthesia absolutely needed additional application of sedation or analgesia, especially during the formation of the subcutaneous tunnel, and neither patient nor surgeon were satisfied with the achieved comfort. During the course of neuroleptic anesthesia with Thalamonal hypotension developed, in 17/20 patients an in 2/20 the presence of prolonged apnea demanded additional artificial ventilation. In the patient operated on in ketamine anesthesia, an acute psychotic reaction developed, followed by visual and acustic hallucinations without signs of metabolic encephalopathy. On the basis of our own experience, we conclude that general neuroleptic anesthesia with the use of Flormidal as an anesthetic and Fentanil as an analgetic, is the method of choice, and that local anesthesia can be recommended only on one operative site (except the subcutaneous tunnel).

The mechanism causing influenza-virus-associated encephalopathy is unclear, even though diclofenac metabolites may induce this pathogenesis. CYP2C9 is known as the major cytochrome P450 gene product that catalyzes diclofenac in human liver. It is uncertain whether the mutation of CYP2C9 is associated the pharmacologic effects of diclofenac in influenza infection. Therefore, we applied a simple and rapid procedure involving real-time fluorescence allele-specific PCR(TaqMan-ASA) assay and denaturing HPLC assay to detect the mutation of CYP2C9 gene. A single-base mutation in the CYP2C9 gene was found in one of thirty subjects in the healthy population. We suggest that this mutation in the CYP2C9 gene may be related to diclofenac-induced influenza-virus-associated encephalopathy.

To study the pre- and intraoperative causes of hemodynamic disorders at the basic stages of liver transplantation in adult recipients, case histories and anesthesia protocols were analyzed in detail in 15 recipients of the cadaveric liver (Group 1) and 60 recipients of a liver portion taken from a living relative donor (Group 2). The patients' preoperative status, the etiology of the disease, the pattern and scope of preoperative preparation and examination, the cause of anesthesia, the volume, pattern, and rate of infusion were studied. Particular emphasis was placed on the presence of pathophysiological prerequisites and various intraoperative factors, which are causes of hemodynamic disorders. Orthotopic transplantation of the liver was performed under generalized balanced anesthesia whose major components were the inhalational anesthetics isoflurane and sevoflurane (89.3%) or total intravenous anesthesia based on neuroleptic anesthetics (10.7%). The main causes of hemodynamic disorders were the patients' severe baseline condition, anemia, ascitis, intoxication, encephalopathy, and the specific features of a surgical intervention, blood loss, heavy plasma and perspiration losses, water-electrolyte balance impairments, vein-vein shunt and reperfusion syndrome. Operations of extraordinary duration (longer than 15-20 hours) required higher plasma compensation volumes (36-52 ml/kg). Severest hemodynamic disorders were observed in patients admitted to hospital for emergency transplantation of the cadaveric liver. These patients who are to undergo transplantation are outside hospital in most cases, which is why any operation should be regarded in them as an emergency one made in patients who are in a very severe state (ASA IV-VE).

Maternal morbidity and mortality in the United States continues to be high. Understanding parturient complications and causes of death is critical to determine corrective actions. Analysis of closed malpractice claims evaluates patient care, identifies preventable morbidity and mortality, and offers recommendations for improvement. A review of obstetric anesthesia malpractice claims filed against nurse anesthetists (N = 21), extracted from the American Association of Nurse Anesthetists Foundation Closed Claims database, was completed. The malpractice claims included 18 maternal claims and 3 neonatal claims. The most common adverse maternal outcomes were maternal death (8/18) and nerve injury (4/18). Hemorrhage accounted for the greatest number of maternal deaths (3/8) followed by cardiovascular failure, emboli, and neuraxial opioid overdose. All neonatal claims (3/3) involved hypoxic encephalopathy resulting in 1 neonatal death and 2 cases of neonatal permanent brain injury. The majority of maternal cases were identified as nonemergent (15/18) and involved relatively healthy patients (15 identified as ASA physical status 2). Qualitative analysis of closed claims provides the opportunity to identify patterns of injuries, precipitating events, and interventions to improve care. Themes related to poor outcomes in this study include care delays, failed communication, incomplete documentation, maternal hemorrhage, and lack of provider vigilance.
