This paper introduces the airway care of a patient with motor neuron disease treated with mechanical ventilation for eight years. The airway care for the patient focused on individualized suctioning,measures to prevent atelectasis such as lung hyperinflation,adjustments of ventilator parameters,regular weaning exercise,as well as measures to prevent ventilator-associated pneumonia such as prevention of aspiration,strict disinfection and isolation,wound care of tracheotomy. The ventilator-associated pneumonia was effectively prevented. Effective nursing care for patients with long-term mechanical ventilation can prevent atelectasis and ventilator-associated pneumonia.

Objective:To construct the enteral nutrition nursing scheme of ICU patients with abdominal hypertension based on internal abdominal pressure classification, and provide reference for effectively preventing enteral nutrition intolerance of ICU patients with abdominal hypertension.Methods:According to the "6S" evidence pyramid model, searched from top to bottom for relevant literature on enteral nutrition support for ICU patients with abdominal hypertension in databases such as BMJ Best Practice, Cochrane Library, Guidelines International Network, Medlive, UpToDate, PubMed, Ovid, Web of Science, Embase, China National Knowledge Infrastructure, VIP, Wanfang Medicine, Chinese Biomedical Literature. Developed an enteral nutrition care plan for ICU patients with abdominal hypertension based on intra-abdominal pressure grading, with a search date from database establishment to January 25, 2023. The Delphi expert letter consultation method was used to conduct two rounds of letter consultation with 20 experts to solicit expert opinions and determine the intervention plan.Results:The age of 20 experts was (43.75 ± 5.28) years old, with a working experience of (22.00 ± 6.98) years. The effective recovery rates of the two rounds of Delphi expert correspondence questionnaires were 100%(20/20), the expert judgment basis coefficients were 0.945 and 0.970, the familiarity coefficients were 0.865 and 0.895, and the authority coefficients were 0.905 and 0.932, respectively. Kendall coordination coefficient of importance of the first, second and third level items in the two rounds of expert correspondence were 0.100, 0.093, 0.098 and 0.200, 0.165, 0.119. The Kendall coordination coefficients of operability for the first, second and third level items were 0.117, 0.130, 0.115 and 0.200, 0.184, 0.154, respectively. Finally, an enteral nutrition nursing scheme for patients with abdominal hypertension in ICU was formed, which included 5 primary items, 30 secondary items and 51 tertiary items.Conclusions:The Delphi method in this study has a high degree of authority and enthusiasm of experts, and a good degree of coordination of expert opinions. The established enteral nutrition nursing scheme for ICU patients with abdominal hypertension based on intra-abdominal pressure classification is reliable and scientific, and can provide reference for clinical nursing practice of enteral nutrition for ICU patients with abdominal hypertension.
