At present, the treatment of laryngeal cancer is mainly surgical treatment or postoperative radiotherapy. The surgery is delicate, complex, time-consuming and traumatic. Postoperative patients are prone to dysphagia, leading to an increase in the incidence of malnutrition. Malnutrition can cause a series of negative effects, including weight loss, increased incidence of infection, reduced tolerance of anti-tumor treatment, and extended length of hospital stay. Therefore, how to effectively improve the nutritional status of laryngeal cancer patients through nursing intervention has become an important topic of nursing research. Objective: Investigate the effect of individualized nutrition intervention care combined with swallowing training on postoperative nutritional status in patients with laryngeal cancer. Methods: A total of 120 consecutive patients who underwent laryngeal surgery at our hospital for the first time between May 2018 and May 2021 were selected for the study and equally divided into the control group and the study group by the random number table method, with 60 patients in each group. Patients in the control group were given swallowing function training and health counseling, and the study group adopted individualized nutrition intervention care based on the control group. The nutritional status, swallowing function, and quality of life (QOL) of the patients were assessed using the Patient-generated Subjective Global Assessment (PG-SGA), MD Anderson Dysphagia Inventory (MDADI), and Quality of Life Questionnaire-Core30 (QLQ-C30) before the intervention and three months after the intervention. Results: Before the intervention, the scores of MDADI, PG-SGA, and QLQ-C30 were not significantly different between the two groups (P > 0.05), and three months after the intervention, the scores of MDADI and QLQ-C30 increased and the score of PG-SGA decreased in the study g展开更多

Methods: 146 patients with oral cavity malignancies admitted to our hospital from January 2019 to July 2021 were selected as the research subjects. 73 patients treated with midline catheters during the treatment were the experimental group, and another 73 patients were treated with indwelling needles as the control group. The indwelling time, total number of puncturing times, and incidence of adverse reactions of two catheterization methods were compared between the two groups. Meanwhile, each patient was investigated for treatment satisfaction. Result: The indwelling time was significantly longer in the experimental group than in the control group (P < 0.0001), and the total number of puncturing times in the experimental group was significantly lower than that in the control group (P < 0.0001). The incidence of adverse reactions in the experimental group (χ<sup>2</sup> = 4.960, P = 0.0259) was significantly lower than that in the control group in terms of catheter occlusion (χ<sup>2</sup> = 12.56, P = 0.0004), catheter detachment (χ<sup>2</sup> = 8.46, P = 0.0036), drug extravasation (χ<sup>2</sup> = 3.27, P = 0.0011), phlebitis (χ<sup>2</sup> = 3.62, P = 0.0003), and bleeding from the puncture point (χ<sup>2</sup> = 14.98, P = 0.0001). The satisfaction rate (χ<sup>2</sup> = 33.45, P < 0.0001) and fundamental satisfaction rate (χ<sup>2</sup> = 16.57, P < 0.0001) in the experimental group were significantly higher than those in the control group, while the dissatisfaction rate was significantly lower than that in the control group (χ<sup>2</sup> = 11.38, P = 0.0007). The difference is statistically significant. Conclusion: Compared with indwelling needle, the application of midline catheters in patients with oral cavity malignancies during perioperative period can effectively reduce the number of puncturing times and the incidence of c展开更多
