Preventive Effect of Intensive Nursing Intervention of Deep Vein Thrombosis of Lower Extremities in Elderly Patients with Gastrointestinal Tumors after Surgery

Tumors of the gastrointestinal system, known as gastroenteropapillary neoplasms, are very uncommon yet have a high propensity to progress to cancer. Thromboembolism of the veins (VTE) is a potentially deadly complication of surgery. In the vast majority of cases, deep vein thrombosis (DVT) in the lower extremities is the primary symptom of VTE (DVT). Deep vein thrombosis is more common in critical care units, where the prevalence ranges from 18 to 50 percent. DVT is a common complication after gastrointestinal tumor surgery, and proper nursing care is essential to lowering the risk of VTE. This research was thus done to examine if intensive nursing interventions may reduce the risk of lower limb DVT in elderly patients who had undergone surgery for gastrointestinal malignancies. The data is separated into two categories: control and treatment. As a self-care theory-based intervention strategy, we propose a hybridized KAP (knowledge, attitude, and practice) approach. Using the twin-bound decision tree algorithm (TBDTA), clinical outcomes including survival and patient satisfaction are examined. There was a considerable improvement in the treatment of DVT compared to the control group and a decrease in typical postoperative conditions. The bundles of care treatment have made a significant increase in the quality of nursing care.
