CT Image Changes of Severe Acute Pancreatitis Based on Smart Electronic Medical Augmented Reality in Nursing Practice

Severe acute pancreatitis (SAP) is traditionally treated with chemical analysis. Faced with the increasing maturity of CT imaging technology, it is necessary to use more advantageous CT imaging to treat SAP. In this article, 72 SAP patients admitted to the Affiliated Hospital of Southwest Medical University were selected for study, of which 62 were severely ill, 8 were exacerbated, and 2 changed from severe to mild. This article combines the patient's case records and related CT images during treatment from the perspective of nursing and conducts nursing research on the application of CT image changes in severe acute pancreatitis in nursing practice. CT image processing uses CT imaging system workstation (DICOM). The results of the study showed that, in the care of patients, 21 cases had recurrence after internal drainage, and the cure rate was 91.1%. Internal drainage is an effective way to treat SAP. The higher the incidence of pancreatitis, the more likely it is to relapse after SAP internal drainage, which may be related to repeated episodes of pancreatitis and repeated inflammation of the pancreas and pancreatic duct damage. 4 of the relapsed cases in this article are postchronic pancreatitis SAP, and the relapsed cases account for 50% of the chronic pancreatic cases. This may be due to chronic fibrosis of the branched and main pancreatic ducts, continuous abnormal pancreatic juice drainage. Therefore, it is necessary to further explore the prognosis of different causes of SAP. In terms of complication care, the overall complication rate was 16.6%. One patient died of postoperative hemorrhage. Analysis of the causes of cyst recurrence and complications may be closely related to the mechanism of the occurrence and development of SAP. The initiating factor of SAP is that the pancreatic tissue is damaged due to inflammation, trauma, or microcirculation disorder, and then the pancreatic juice leaks out of the pancreas, wrapping the pancreatic juice; it takes a certain time for the capsule of fibrous knot tissue to form and strengthen.
