ABSTRACT

BACKGROUND: Acute renal insufficiency (ARI) usually occurred following liver transplantation due to the surgical trauma and the application of immunosuppressant, which lack of unified diagnostic criteria. OBJECTIVE: To investigate the experience of diagnosis and treatment of ARI following liver transplantation.DESIGN, TIME AND SETTING: The experiment was performed at the 458 Hospital of Chinese PLA from January 2004 to December 2006.PARTICIPANTS: A total of 37 cases received liver transplantation, including 35 males and 2 females, aged 37-67 years, mean aged (48.5±8.9) years. All cases were divided into the liver cancer group (n=16) and liver cirrhosis group (n=21). The liver cirrhosis group included 16 cases with posthepatitic type B cirrhosis, 4 with posthepatitic type C cirrhosis, and 1 with alcoholic cirrhosis. All these cases were in decompensation stage. The final diagnosis was performed by pathological examination. METHODS: The removal of kidney and construction of blood outflow tract was achieved by modified piggy-back liver transplantation. The arterial blood gas analysis, blood routine examination, renal function and liver function were examined more than twice per day. The cephalosporins, Fluconazole and ganciclovir or vancomycin were used for 5-7 days to prevent infections.MAIN OUTCOME MEASURES: The incidence rate of acute ARI, clinical features and outcomes of patients were observed.RESULTS: ARI developed in 19 patients with liver transplantation, 5 patients died, 14 patients recovered in 2-3 weeks. The incidence of ARI following liver transplantation was associated with infection, bleeding shock, respiratory failure and acute respiratory distress syndrome (P < 0.05). CONCLUSION: The incidence of ARI following liver transplantation was 51.35%, with 26.32% mortality rate. The early diagnosis and treatment are the key steps for increasing successful rate of ARI treatment following liver transplantation.

ABSTRACT

Objective To study the application of pressure regulated volume control ventilation in respiratory support after liver transplantation.Methods Twenty patients underwent liver transplantation were randomly averagely divided into two groups: pressure regulated vlume control ventilation(PRVCV) group and volume control(VC) group.The parameters of respiratory mechanics,hemodynamics and blood gas analysis of patients in two groups were compared,such as oxygen delivery(DO2),oxygen consumption(VO2),oxygen incepation ratio(O2ER),arteriovenous oxygen content difference(C(a-v)O2),cardiac output(CO),mean arterial pressure(mABP),mean pulmonary arterial pressure(mPAP),alveolar-arterial PO2 difference(P(A-a)O2),gas exchange index(PaO2/FiO2),ratio of shunted blood to total perfusion(Qs/Qt),peak inspiratory pressure(PIP) and mean airway pressure(mAP).Results The P(A-a)O2 and Qs/Qt were significantly decreased in PRVCV group than those in VC group(P(A-a)O2:(101.42?28.07) mm Hg vs.(136.76?39.13) mm Hg;Qs/Qt:(1.78?0.86)% vs.(3.28?0.99)%),P

ABSTRACT

BACKGROUND: Intrapulmonary vascular abnormalities result in the right-to-left shunting and severe hypoxemia in liver transplantation candidates. Currently, a convenient, sensitive and effective method is absent to screen the intrapulmonary vascular dilatations.OBJECTIVE: To evaluate the role of contrast-enhanced echocardiography on clinical diagnosis of intrapulmonary shunting in liver transplantation candidates.DESIGN, TIME AND SETTING: The experiment, prospective controlled observation based on cases, was performed at the Hepatology Unit of the 458 Hospital of PLA (Guangzhou, Guangdong, China) from February 2004 to February 2006.PARTICIPANTS: Twenty-four consecutive liver transplantation candidates were recruited from the Hepatology Unit of the 458Hospital of PLA.METHODS: Routine examination was conducted under the condition without any regimen of vascular dilatation drugs.Contrast-enhanced echocardiography was applied to detect the prevalence of right-to-left shunting in the patients with end-stage liver disease. The microvesicle of the left ventricle in patients was qualitatively assessed by a score from 1+ to 3+. Accordingly, all patients were divided into two groups: intrapulmonary shunting and non-intrapulmonary shunting.MAIN OUTCOME MEASURES: The prevalence of right-to-left shunting and clinical characteristics of liver transplantation candidates were determined.RESULTS: Ten (41.7%) of 24 patients with positive contrast-enhanced echocardiography were proved to develop the intrapulmonary right-to-left shunting, including 6 for l+ and 4 for 2+ by left ventricle abnormality, which emerged after 6-10 cardiac cycles of right ventricle abnormality. There were no significant differences in age, gender, arterial blood gas analysis and liver function tests between the two groups (P > 0.05). Echocardiography results demonstrated that, the upper digestive tract hemorrhage,spleen thickness that indicated portal hypertension, pulmonary artery systolic pressure and Tei index were significandy higher in the patients of intrapulmonary shunting than in those of non-intrapulmonary shunting (P<0.05-0.01 ).CONCLUSION: Intrapulmonary vascular dilatation occurs frequently in liver transplantation candidates associated with intrapulmonary shunting but without hypoxemia. Contrast-enhanced echocardiography is a sensitive and non-invasive method for the early diagnosis of intrapulmonary vascular dilatation. The pathogenic cause is portal hypertension. Tel index can be used as an important parameter for evaluating right ventricular function in patients of intrapulmonary vascular dilatation.

ABSTRACT

Objective To investigate the clinical significance of the electrocardiogram (ECG) to cardiac involvements in Systemic lupus erythematosus (SLE). Methods 80 cases without sign and syndrome of cardiac involvements were analyzed retrospectively in our hospital between January 2004 and April 2009.Results In 80 cases without sign and syndrome of cardiac involvements, 46 cases had ECG changes,with the positive rate being 57.5% . In the next echocardiography examination, 39 cases had heart struction or function change,with the positive rate being 48.8% . Conclusion For SLE patients, ECG examinations can find the change,and in the next echocardiography examination, cardiac involvements degree can be sure. It can provid an early important information for diagnose and treatment.

ABSTRACT

Objective To study the relationship of social support and quality of life of liver transplantation patients, investigating the effective measures to improve their life quality. Methods Questionnaires were filled in by 90 liver transplantation patients and a descriptive study was used. Results Positive correlation was found between social support and life quality of liver transplantation patients. Conclusion Social support was related to the life quality of liver transplantation patients. Nurses should pay attention to the effect of social system to improve their life quality.
