肝脏具有复杂的代谢功能和强大的代偿能力。对肝脏功能损害程度和储备功能的判断,一直是人们关注的热点。术前肝储备功能的正确评估,对肝硬化.特别是肝癌肝叶切除术患者在外科临床更显重要。肝功能衰竭是肝癌切除术后严重的并发症,也是导致术后死亡的主要原因。肝功能衰竭的发生.主要与肝硬化引起的肝脏储备功能下降有关,也与手术过程,包括切除肝脏体积、术中出血、阻断肝门血流与否以及围手术期的处理等有关。术前正确评估肝脏储备功能,术中合理掌握切肝量,是避免术后肝功能衰竭的重要措施。 相似文献

OBJECTIVE: To determine perioperative changes in circulating (BVI) and central blood volume (CBVI) by a new dye dilution technique using pulse dye densitometry. DESIGN AND SETTING: Prospective observational study in the cardiac anesthesia and intensive care unit of a university hospital. PATIENTS: Sixty-six patients undergoing coronary artery bypass surgery. MEASUREMENTS AND RESULTS: Hemodynamic measurements by the dye dilution method using pulse dye densitometry were performed prior to skin incision and 3.3+/-1.4 h and 17+/-2.7 h after surgery. Based on conventional monitoring the therapeutic goals of hemodynamic therapy were achieved in all of the patients of this study. Despite a marked positive fluid balance which developed during surgery mean BVI decreased significantly after surgery while CBVI remained unchanged. Postoperative BVI deficits vs. preoperative values were observed in 78% of patients; these BVI deficits were profound in 29% of the cases. In contrast, 65% of the individual patients showed no or only minor postoperative changes in CBVI vs. preoperative values. CONCLUSIONS: Changes in the intravascular volume compartments affected BVI to a greater extent than CBVI. Therefore measuring circulating in addition to central blood volume may be useful to ensure a normal circulating blood volume that can compensate for any change in the central vascular compartment. 相似文献

Methodological limitations of the use of intrinsic hepatic clearance of ICG as a measure of liver cell function 总被引:1,自引:0,他引:1
Abstract Negligible extra-hepatic elimination of indocyanine green (ICG) makes it well suited as a liver test substance. The liver blood flow rate ( Q ) is estimated from concentration measurements in peripheral ( A ) and hepatic venous ( V ) blood during a constant ICG infusion rate (Inf), as Q = Inf/( A – V ). Intrinsic hepatic clearance of ICG, Cli = Inf/((A – V)/In( A/V )), is interesting because it should give a flow-independent quantitative estimate of liver cell function, utilizing the same concentration measurements. The present study was aimed to investigate possible limitations involved in the estimation and use of Cli of ICG in 41 liver patients and 20 controls. Time-dependence was studied by means of two successive 40-min infusion periods (with no significant change in Q ). Cli of ICG decreased 6% per hour ± 3% (mean ± SD, n = 6, P < 0·01) due to a small but significant increase of the concentrations during the infusion period. Flow-dependence was studied by measurements before and after an increment of flow of on average 51%, induced by the intake of a meal. This caused no significant change in Cli of ICG ( P > 0·5, n = 5, Student's paired t -test). The intrinsic hepatic clearance of ICG was on average 0·75 ± 0·26 1 plasma min-1 (± SD, n = 20) in controls and 0·39 ± 0·18 1 plasma min-1 in liver patients ( n = 41), P < 0·001. It was positively correlated to the galactose elimination capacity, although the scatter was large ( P < 0·05, n = 56). This might be due to the fact that Cli depends both on liver cell function and on intra-hepatic vascular shunting of blood. 相似文献

目的探讨Child-Turcotte-Pugh(CTP)评分与CT灌注成像在肝硬化患者肝储备功能评估中的相关性及其临床意义。方法选择30例肝硬化患者(肝硬化组)及30例健康对照者(对照组),进行CTP评分,并行多层螺旋CT灌注扫描,计算灌注参数:门静脉灌注量(HPP)、肝动脉灌注量(HAP)、总肝灌注量(TLP)和肝动脉灌注指数(HPI),评价肝硬化患者的CT灌注成像各项参数与CTP评分之间的相关性。结果肝硬化组与对照组比较,HPP〔(0.4958±0.2313)vs(0.9356±0.2679)ml/min·ml,P=0.000〕、TLP〔(0.8437±0.3242)vs(1.1326±0.3720)ml/min·ml,P=0.022〕均降低,差异有统计学意义。肝硬化组CTP评分与HPP(r=-0.793,P=0.000)、与TLP(r=-0.815,P=0.021)均呈负相关。结论与CTP评分体系相比,CT灌注参数可反映肝硬化患者肝脏的血流灌注情况,对肝储备功能评估有一定指导作用。 相似文献

BACKGROUNDAs transjugular intrahepatic portosystemic shunt (TIPS) creation alters the hemodynamic status of the portal system, whether reduced portal blood supply affects the synthetic reserve function of the liver has been the focus of clinical attention. Since the Viatorr stent entered the Chinese market in 2015, it has not yet been widely used in clinical practice. Further, unlike other countries, the main cause of liver cirrhosis in China is viral hepatitis. Therefore, use of the Viatorr stent to establish a TIPS channel in patients with liver cirrhosis with differing etiologies is of great clinical interest.AIMTo investigate factors affecting changes in liver reserve function after TIPS Viatorr stent implantation.METHODSClinical data from 200 patients with cirrhotic portal hypertension who received TIPS treatment from March 2016 to March 2020 were analyzed retrospectively. The patients were divided into three groups (A-C), according to their disease etiology, with post-hepatitis, autoimmune, and alcoholic cirrhosis, respectively. Preoperative and postoperative liver and renal function and coagulation data, Child-Pugh grade, and model for end-stage liver disease (MELD) scores were collected. Statistical analyses were performed using the t-test or chi-square test. The incidence and of hepatic encephalopathy and patient survival were calculated using Kaplan-Meier method.RESULTSThe surgical success rate was 100%, with mean portal pressure gradient (mmHg) decreasing from 25.5 ± 5.22 to 10.04 ± 2.76 (t = 45.80; P < 0.001). After 24 mo, the cumulative incidence of hepatic encephalopathy in group A was significantly lower than that in group B/C, while the cumulative survival rate was significantly higher in group A than in group B/C (P < 0.05 for both). The Child-Pugh score for group A was 6.96 ± 1.21, which was significantly better than those of groups B (7.42 ± 0.99; t = -2.44; P = 0.016) and C (7.52 ± 1.12; t = -2.67; P = 0.009). Further, the MELD score for group A (9.62 ± 2.19) was significantly better than those for groups B (10.64 ± 1.90; t = -2.92; P = 0.004) and C (10.82 ± 2.01; t = -3.29; P = 0.001).CONCLUSIONInsertion of 8 mm internal diameter Viatorr stent has no significant effects on liver reserve function. Changes of liver reserve function in the medium and long term may be related to the etiology and treatment of portal hypertension. 相似文献
