研究目的:

评价BIP涂层导尿管预防危重症患者CAUTIs的效果;评估BIP涂层导尿管抑制细菌生物膜形成的能力。  

Objectives of Study:

To evaluate the effect of a silver alloy and hydrogel-coated catheter against catheter-associated urinary tract infection in critically ill patients and the ability of a silver alloy and hydrogel-coated catheter to inhibit bacterial biofilm formation.

药物成份或治疗方案详述:

拟将收住重症医学科的需留置导尿并符合入排标准的患者随机分成对照组和观察组。在常规治疗的基础上,对照组留置普通硅胶导尿管,观察组留置BIP合金涂层导尿管。收集两组患者的临床资料。分别于第0,3、7、10、14天收集尿液标本,进行尿常规及尿培养检查。一旦患者被诊断为CAUTIs,即刻更换导尿管,给予相应的抗感染治疗并终止观察。于留置导尿第14天所有受试者拔出尿管,采用菌落计数法对尿管不同段生物膜中活菌数量(CFU)进行半定量评估。 

Description for medicine or protocol of treatment in detail:

Patients admitted to the intensive care department for catheterization and meet the entry criteria will be randomly divided into control and observation groups.On the basis of conventional treatment, the control group had a common silicone catheter welling, and the observation group had a silver alloy and hydrogel-coated catheter. Clinical data were collected from both patient groups. Urine samples were collected on days 0, 3, 7, 10 and 14 for routine urine and urine culture examinations. Once the patient was diagnosed with CAUTIs, the catheter was replaced immediately, the corresponding anti-infection treatment was given and the observation was terminated. The number of live bacteria (cfu) in different sections of the biofilm in the urinary catheter.  

纳入标准:

1.需留置导尿管的危重症患者;
2.年满18岁;
3.预计留置导尿时间超过14天。

Inclusion criteria

1. Critically ill patients who need indwelling urinary catheter;
2. Aged at least 18 years;

2.恶性肿瘤患者、血液系统疾病、自身免疫性疾病或免疫缺陷的患者;
3.存在结构性尿路疾病(如前列腺增生、泌尿系结石、尿道畸形等)等疾病史;
4.入住前已行留置导尿时间超过48h的患者;
5.入住ICU前已存在泌尿系感染或隐性感染的患者;
6.急慢性肾功能损伤患者。

Exclusion criteria:

1. Patients with a history of glucocorticoid and immunosuppressant drugs;
2. Patients with malignant tumors, patients with hematological diseases, autoimmune diseases or immune defects;
3. History of structural urinary tract diseases (such as prostatic hyperplasia, urinary calculi, urethral malformation, etc.);
4. Patients who have undergone indwelling catheterization for more than 48 h before admission;
5. Patients with urinary tract infection or recessive infection existing before being admitted to icu;

随机方法(请说明由何人用什么方法产生随机序列):

本研究由随机专员采用 SAS9.4 软件进行区组随机,设定样本量、组间比例(1:1)、区组长度、区段数、种子数生成随机号盲底,将生成的随机号盲底导入中央随机化系统(IWRS)中。在研究中每例受试者被分配到试验组或对照组将由随机化系统确定。随机表具有可重现性,所设定的种子数等参数记录在随机文件中。 本研究受试者筛选号格式为 S+6 位阿拉伯数字。前 2 位数字为中心号,后 4 位数字为受试者的筛选顺序号,例如:第 1 中心第 3 例参加筛选的受试者筛选号为“S010003”。筛选成功的受试者按照随机化的顺序获取随机号,随机表中随机号格式为 3 位阿拉伯数字,例如:随机号“005”对应的受试者为筛选成功后第 5 个进行随机化的受试者。筛选合格的受试者随机分配到不同的治疗组。 两种导尿管外观上无明显差异,对商标等标识处给予覆盖,使研究对象无法辨认出导尿管类型,即给予单盲处理。

Randomization Procedure (please state who generates the random number sequence and by what method):

In this study, the randomized specialist used SAS9.4 software to randomize groups, set the sample size, group ratio (1:1), group length, section number and seed number generated random blind base, and the generated random blind base was introduced into the central randomization system (IWRS).
