Smart medical care is user-centric, medical information is the main line, and big data, Internet of Things, cloud computing, artificial intelligence, and other technologies are used to establish scientific and accurate information, as well as an efficient and reasonable medical service system. Smart medical plays an important role in alleviating doctor-patient conflicts caused by information asymmetry, regional health differences caused by irrational allocation of medical resources, and improving medical service levels. This article mainly introduces the remote care assistance system of emergency department based on smart medical and intends to provide some ideas and directions for the technical research of patients in emergency department receiving remote care. This paper proposes a research method for remote care assistance in emergency departments based on smart medical, including an overview of remote care based on smart medical, remote care sensor real-time monitoring algorithms based on smart medical, signal detection algorithms, and signal clustering algorithms for smart medical. Remote care in the emergency department assisted in research experiments. The experimental results show that 86.0% of patients like the remote care system based on smart medical studied in this paper.

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.

Meta‐analysis research was implemented to appraise the effect of various repositioning regimens (RRs) on pressure wound ulcer (PWU) occurrence in at‐risk adult persons without existing PWUs. Inclusive literature research till April 2023 was done and 1197 interconnected researches were revised. The 15 picked researches, enclosed 8510 at‐risk adult persons without existing PWUs persons were in the utilised researchers' starting point, 1002 of them were utilising repositioning, 1069 were control, 3443 were utilising 2–<4 h repositioning and 2994 were utilising 4–6 h repositioning. Odds ratio (OR) and 95% confidence intervals (CIs) were utilised to appraise the consequence of various RRs on PWU occurrence in at‐risk adult persons without existing PWUs by the dichotomous approach and a fixed or random model. Repositioning had significantly lower PWU (OR, 0.49; 95% CI, 0.32–0.73, p < 0.001) compared to control in at‐risk adult persons without existing PWUs persons. 2–<4 h repositioning had significantly lower PWU (OR, 0.62; 95% CI, 0.42–0.90, p = 0.01) compared to 4–6 h repositioning in at‐risk adult persons without existing PWUs persons. Repositioning had significantly lower PWU compared to control in at‐risk adult persons without existing PWU persons. 2–<4 h repositioning had significantly lower PWU compared to 4–6 h repositioning in at‐risk adult persons without existing PWUs persons. However, caution needs to be taken when interacting with its values since there was a low sample size of some of the chosen research found for the comparisons in the meta‐analysis.
