醫(yī)學免費論文:高容量血液濾過在肝移植術后多器官功能障礙綜合征患者中的應用
【摘要】 探討高容量血液濾過(HVHF)在肝移植術后因嚴重感染引起多器官功能障礙綜合征(MODS)患者中的應用。 【方法】 分析2003年12月至2008年12月肝移植術后因感染引起MODS進行連續(xù)性血液凈化治療74例患者的臨床資料,根據超濾率是否大于35 mL·kg-1·h-1分為HVHF組(49例)和連續(xù)性靜脈-靜脈血液濾過(CVVH)組(25例)。記錄治療前和治療后24、48、72 h APACHⅡ評分、電解質、血流動力學和呼吸功能各項指標,以及臨床轉歸。分別對組內治療后各時間點與治療前以及兩組間各時間點之間的觀察指標進行比較。 【結果】 HVHF組患者,APACHⅡ評分、乳酸、肌酐、心率、多巴胺用量、氣道平均壓和氣道峰壓、氧合指數(shù)等指標在治療后24、48、72 h較治療前明顯下降(P < 0.05)。CVVH組患者,APACHⅡ評分、乳酸、氣道平均壓和氣道峰壓值治療前后無明顯變化(P > 0.05),心率、多巴胺用量和氧合指數(shù)雖較前有所改善,但程度均不如HVHF組(P < 0.05)。HVHF組病死率為59.2%(29/49),CVVH組為84.0%(21/25),兩者具有統(tǒng)計學差異(P = 0.031)!窘Y論】 HVHF通過維持機體內環(huán)境的穩(wěn)定,為其他治療創(chuàng)造有利條件,有助于提高肝移植術后危重患者的生存率。

Application of High Volume Hemofilatration on Patients with Multiple OrganDysfunction Syndrome after Liver Transplantation LI Min-ru, HUANG Zheng-yu, CAI Chang-jie, YI Hui-min, AN Yu-ling, WEI Min, CHEN Gui-hua Liver Transplantation Center, The Third Affiliated Hospital of Sun Yat-sen University, Guangzhou 510630, ChinaAbstract: 【Objective】 To investigate the effect of high volume hemofilatration (HVHF) in the patients with MODS induced by severe infection after liver transplantation. 【Method】 Seventy-four patients with MODS caused by severe infection after liver transplantation who have received continuous blood purification (CBP) from December 2003 to December 2008 were divided into two groups according to ultrafiltration rate: HVHF group (49 patients) and CVVH group (25 patients). APACHⅡ score, electrolyte, hemodynamic and respiratory index were monitored pre and 24 h, 48, and 72 h post-CBP. 【Results】 APACHⅡscore, lactate(Lac), creatinine(Cr), heart rate(HR), dopamine dosage, mean airway pressure(Pmean), peak air pressure(Ppeak) and PaO2/FiO2 were improved significantly (P < 0.05) after treatment in HVHF group (49 cases). There were no significant change(P > 0.05) of APACHⅡscore, Lac, Pmean and Ppeak between post and pre-treatment in CVVH group (25 cases). Although Cr, HR, dopamine dosage, and PaO2/FiO2 were improved, but they were not as ameliorated as HVHF group (P < 0.05). The mortality rate of HVHF group was 59.2%(29/49), and that of CVVH group was 84.0% (21/25). There was significant difference between them (P = 0.031). 【Conclusion】 CBP can maintain internal environment stable, create lucrative condition for other treatment and help to increase the survival rate of the critical patients after liver transplantation.

多器官功能障礙綜合征(multiple organ dysfunction syndrome, MODS)是肝移植術后常見且預后較差的并發(fā)癥,嚴重感染是其最主要的誘因,目前尚缺乏療效確切的治療方式,其死亡率可高達86.7%[1]。如何降低這部分患者的死亡率是提高肝移植圍術期生存率的關鍵。連續(xù)性血液凈化技術(continuous blood purification, CBP)被認為是治療MODS尤其是合并急性腎功能不全患者的重要手段。據報道高容量血液濾過(high volume hemofilatration,HVHF)作為CBP的一種新模式(指超濾率 > 35 mL·kg-1·h-1的連續(xù)性靜脈-靜脈血液濾過)可改善嚴重感染及其所引起MODS患者的生存率[2],但目前國內外尚無關于其用于治療肝移植術后MODS的報道。因此我們對部分肝移植術后由感染引起MODS的患者施行HVHF治療,并與傳統(tǒng)連續(xù)性靜脈-靜脈血液濾過(continuous veno-venous hemofiltration, CVVH)進行比較(低容量CVVH),觀察其對患者病理生理以及生存率的影響。
