PICC refers to peripherally inserted central venous catheter, which plays an important role in the treatment of malignant tumor patients with chemotherapy, and it has the characteristics of high success rate of puncture and reducing the pain of patients. Its principle is to use PICC catheter for drug delivery, which can effectively reduce the pain of tumor patients for multiple puncture, and also can avoid drug extravasation or local stimulation of drugs. However, PICC catheter-related complications cannot be ignored, to some extent, directly affect the treatment effect of patients, and increase the pain and burden of patients. Therefore, this paper proposes a study of PICC catheter-related complications and protective nursing for patients with digestive system cancer based on smart medical block chain. First of all, using the method of literature, this paper deeply studied the combination of smart medicine and block chain and further strengthened the research on PICC catheter-related complications. Based on this, we designed a study on the prevention and nursing of PICC catheter-related complications in patients with digestive system cancer. Before the implementation of nursing, the incidence of complications in patients with digestive system cancer was 17.35%; after the implementation of nursing, the incidence of complications decreased to 4.08%. The purpose of this study is to analyze the causes through clinical research and put forward the protective nursing measures of related diseases, so as to reduce the incidence of PICC-related complications.<\/jats:p>","DOI":"10.1155\/2021\/5519722","type":"journal-article","created":{"date-parts":[[2021,4,13]],"date-time":"2021-04-13T20:10:43Z","timestamp":1618344643000},"page":"1-11","source":"Crossref","is-referenced-by-count":3,"title":["Prevention and Nursing Research of PICC Catheter-Related Complications in Patients with Digestive System Malignant Tumor Based on Smart Medical Block Chain"],"prefix":"10.1155","volume":"2021","author":[{"given":"Ruxian","family":"Huang","sequence":"first","affiliation":[{"name":"Gastrointestinal Surgery, The Central Hospital of Wuhan, Tongji Medical College Huazhong University of Science and Technology, Wuhan 430000, Hubei, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Gastrointestinal Surgery, The Central Hospital of Wuhan, Tongji Medical College Huazhong University of Science and Technology, Wuhan 430000, Hubei, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4562-4760","authenticated-orcid":true,"given":"Xiaoyun","family":"Le","sequence":"additional","affiliation":[{"name":"Gastrointestinal Surgery, The Central Hospital of Wuhan, Tongji Medical College Huazhong University of Science and Technology, Wuhan 430000, Hubei, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1080\/10376178.2020.1741417"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2020.03.039"},{"issue":"4","key":"3","doi-asserted-by":"crossref","first-page":"83","DOI":"10.4018\/JOEUC.2018100106","article-title":"Data analytics assisted internet of things towards building intelligent healthcare monitoring systems: IOT for healthcare","volume":"30","author":"K.
