BACKGROUND: We examined the ability of thiopental known to have protective effect on brain to prevent brain damage resulting from cerebral ischemia due to global imbalance in cerebral metabolic rate for oxygen and cerebral blood flow during rewarming period in cardiopulmonary bypass. METHODS: Jugular venous oxygen saturation(SjO2) was used as a reflection of cerebral oxygen balance. Thiopental 20 mg/kg(thiopental 10 mg/kg bolus and 10 mg/kg continuous infusion) was received during rewarming from hypothermic cardiopulmonary bypass of 27~30.5degrees C to 36degrees C and SjO2 compared with control group. RESULTS: In 8 patients of the 25 control group(32%) and 7 patients of the 24 thiopental group(29.2%), SjO2 were < or =50% with no difference between groups. Artery-jugular vein oxygen content differences (C(a-j)O2) and O2 extraction ratios increased significantly in SjO2 < or =50% patients suggesting increased oxygen consumption. Awake time prolonged significantly with thiopental. CONCLUSIONS: Thiopental(20 mg/kg) administration during rewarming in cardiopulmonary bypass for cerebral protection is not recommended.

BACKGROUND: Pulmonary hypertension (PH) associated with end stage liver disease is rare but the risk of hemodynamic deterioration during liver transplantation may be high. This study was done to characterize the pulmonary hemodynamics during liver transplantation and to seek the relationship between pulmonary artery pressure (PAP) and other hemodynamic variables. METHODS: One hundred patients undergoing liver transplantation were chosen and we divided patients into normal and PH groups (mean pulmonary artery pressure [MPAP] > 25 mmHg). Hemodynamic data was collected throughout the surgery. Studied variables between groups were analyzed with an unpaired t-test. The relationship between MPAP and other hemodynamic variables was analyzed with a linear regression test. Survival analysis was performed by cumulative survival analysis (Logrank test). RESULTS: Incidence of PH during liver transplantation was 34%, and true PH (pulmonary vascular resistance index [PVRI] > 150 dyne.sec/cm5/m2, MPAP > 25 mmHg) was 7%. MPAP, systemic vascular resistance index, cardiac index, right ventricular ejection fraction, maximum elastance, central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), and right ventricular end-diastolic volume index were significantly higher in the PH group. In the PH group, right ventricular function curve was abnormal. MPAP correlated significantly with PAOP, and CVP (P < 0.01). One year survival rate showed no significant difference between groups (Logrank test P = 0.49). CONCLUSIONS: Episodes of increased pulmonary artery pressure during liver transplantation was not infrequent. PAP was more dependent on preloads. In patients with high PAP, RV diastolic dysfunction was usually observed. Early mortality rate after liver transplantation was not associated with PH.

Journal of The Korean Society of Clinical Toxicology 2020;18(2):78-84
Purpose:
In acute acetaminophen poisoning, the administration of N-acetylcysteine (NAC) can effectively treat the main complications, such as kidney injury and liver failure. In the current situation, measurements of the acetaminophen concentration are not checked in the usual medical facilities. Therefore, this study examined the factors of determining the administration of NAC in addition to the stated amount of intake.
Methods:
The medical records of patients who visited Ajou University Hospital emergency center with acetaminophen poisoning from January 2015 to December 2019 were reviewed retrospectively. One hundred and seventy-nine patients were initially included. Among these patients, 82 patients were finally selected according to the inclusion criteria in the study. The inclusion criteria were as follows: patients who were 15 years of age or older; those whose ingested dose, ingested time, and body weight were clearly identified; and patients whose acetaminophen sampling time was within 24 hours. Patients were divided into two groups: NAC administered vs. non-NAC administered. The following variables were compared in these two groups: ingested dose, ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, psychiatric disease history, classification of toxicon-toxic groups, duration of hospitalization, and laboratory results.
Results:
Univariate analysis revealed the ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, and psychiatric disease history to be the determining factors in administering NAC. Logistic regression analysis confirmed that the ingested dose per body weight was the only significant factor leading to an NAC treatment decision. (Odds ratio=1.039, 95% Confidential interval=1.009-1.070, p=0.009)
Conclusion
The ingested dose per body weight was the only determining factor for administering NAC in patients with acute acetaminophen poisoning. On the other hand, additional criteria or indicators for the NAC administration decision will be necessary considering the inaccuracy of the ingested dose per body weight and the efficiency of NAC administration.

In advent of high-resolutional CT and MRI, it is not so difficult to detect the lumbar synovial cyst, however the unusual disease should be included in the differential diagnosis of cauda equine compression syndromes. The case of a 55-year-old man who had a low back pain and severe radiating pain on both legs showed a retrolisthesis at L3-4 and L4-5 and epidural enhancing mass just around L4-5 facet joint on MRI. Microscopically a lining of synovial tissue was demonstrated. After surgery of the total resection of synovial cyst and stabilization, the patient's presenting symptoms were improved.

Hepatopulmonary syndrome is essentially the triad of liver disease, pulmonary vascular dilations and abnormal arterial oxygenation, which can result in severe hypoxia. We managed two cases of 9 and 49-year-old males for liver transplantation with hepatopulmonary syndrome. Preoperative evaluation showed decreased diffusion capacity of carbon monooxide and severe hypoxemia, while breathing room air (PaO2 < 60 mmHg) but they responded to oxygen therapy. The pulmonary vascular resistance was low, consistent with an intrapulmonary vascular shunt but the pulmonary artery pressure was normal, reflecting a high cardiac output. Intraoperative oxygenation was satisfactory (PaO2 of 100 - 200 mmHg) in spite of a high shunt fraction (Qs/Qt 18.5 +/- 9.2%). This means that the impairment in gas exchange is not the result of a true shunt, suggesting the presence of a functional shunt, which is characterized by diffusion-perfusion impairment. The intraoperative course was uneventful in the two patients and they are in a successful postoperative course. In case 1, the hypoxemia was resolved promptly, but in case 2, it was persistent for sixteen months after transplantation. The hypoxemia itself in hepatopulmonary syndrome is not regarded as a contraindication to liver transplantation. (Korean J Anesthesiol 2001; 40: 677 ~ 683)

Protein C exerts anticoagulant effects by inactivating factor Va and VIIIa and stimulating fibrinolysis. The homozygous protein C deficiency is extremely rare and often results in life threatening thrombosis and purpura fulminans with necrotic cutaneous lesions. A child with homozygous protein C deficiency was treated at 6 months by a living-related liver transplantaion. After induction of anesthesia, we started an FFP infusion for protein C replacement and a low molecular weight heparin continuous infusion to prevent thrombosis. A complete reconstitution of protein C activity and resolution of the thrombotic condition occured postoperatively. So we report this case with a brief review of the literature.
