摘　　要：目的观察脓毒症相关胆汁淤积性黄疸患者临床特征并分析死亡危险因素。方法收集2011年8月-2019年8月四川省医学科学院·四川省人民医院重症医学中心SICU收治的脓毒症相关胆汁淤积性黄疸患者139例,分为存活组(n=62)和死亡组(n=77)。记录患者年龄、性别、急性生理和慢性健康评分(APACHEⅡ)以及感染部位;记录5个时间点TBil、DBil、IBil、PT、国际标准化比值(INR)、AST、ALT、WBC、中性粒细胞(NEU)、降钙素原(PCT)、乳酸(Lac)数值;同时记录TBil、DBil、IBil峰值,以及血管活性药物时间、机械通气时间、人工肝血浆置换次数、重症监护病房(ICU)住院时间、Child-Pugh分级、黄疸分级。符合正态性和方差齐性的计量资料两组间比较采用独立样本t检验;不符合正态性和方差齐性的计量资料两组间比较采用Mann-Whitney U检验。计数资料两组间比较采用χ2检验。采用二元logistic多因素回归分析进行死亡危险因素分析。结果脓毒症相关胆汁淤积性黄疸患者病死率55.4%。存活组TBil、DBil以及IBil在14 d、21 d、28 d以及峰值水平均显著低于死亡组(TBil:Z值分别为-3.230、-8.197、-9.281,t=-5.371;DBil:Z值分别为-4.708、-8.633、-9.579、-8.238;IBil:Z值分别为-2.402、-6.522、-8.113、-5.300,P值均<0.01);存活组中度黄疸比例高,而死亡组重度黄疸比例高,两组比较差异有统计学意义(χ2=57.633,P<0.01);存活组PT和INR在所有时点(诊断时、7 d、14 d、21 d、28 d)均低于死亡组(PT:Z值分别为-3.173、-3.467、-2.660、-2.261、-3.120;INR:Z值分别为-3.141、-2.754、-3.230、-2.560、-3.229,P值均<0.05);AST在7 d、14 d、21 d及28 d明显低于死亡组(Z值分别为-2.484、-3.200、-3.298、-4.277,P值均<0.05);ALT在14 d、21 d及28 d明显低于死亡组(Z值分别为-2.635、-2.667、-4.656,P值均<0.01);存活组WBC、NEU在7 d、14 d、21 d均显著低于死亡组(WBC:Z值分别为-3.229、-2.987、-4.537;NEU:t=-3.332、Z=-3.107�Objective To investigate the clinical features of patients with sepsis-induced cholestatic jaundice and the risk factors for death.Methods A retrospective analysis was performed for the clinical data of 139 patients with sepsis-induced cholestatic jaundice who were admitted to Surgical Intensive Care Unit,Critical Care Medicine Center,Sichuan Academy of Medical Sciences&Sichuan Provincial People’s Hospital,from August 2011 to August 2019,and the patients were divided into survival group with 62 patients and death group with 77 patients.Age,sex,Acute Physiology and Chronic Health Evaluation II(APACHEII)score,and infection sites were recorded;related laboratory data at five time points were recorded,including total bilirubin(TBil),direct bilirubin(DBil),indirect bilirubin(IBil),prothrombin time(PT),international normalized ratio(INR),aspartate aminotransferase(AST),alanine aminotransferase(ALT),white blood cell count(WBC),neutrophils(NEU),procalcitonin(PCT),and lactic acid(Lac);the peak values of TBil,DBil,and IBil were also recorded,as well as duration of use of vasoactive agent,duration of mechanical ventilation,number of times of artificial liver plasma exchange,length of stay in the intensive care unit(ICU),Child-Pugh class,and jaundice grade.The independent samples t-test was used for comparison of normally distributed continuous data with homogeneity of variance between groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data with heterogeneity of variance between groups;the chi-square test was used for comparison of categorical data between groups;a binary logistic regression analysis was used to investigate the risk factors for death.Results The mortality rate of patients with sepsis-induced cholestatic jaundice was 55.4%.Compared with the death group,the survival group had significantly lower levels of TBil,DBil,and IBil on days 14,21,and 28 and significantly lower peak values of TBil,DBil,and IBil(TBil:Z=-3.230,-8.197,and-9.281,t=-5.371,all P<0.01;DBil:Z=-4.
