Objective. This study examines the effects of the 3S2E nursing management mode on patients with severe pneumonia in the intensive care unit’s respiratory function, psychological status, and quality of life (ICU). Methods. According to a random number table, 82 ICU patients with severe pneumonia who were admitted between March 2021 and March 2022 were enrolled and assigned to the control and observation class (n = 41, respectively) in a 1 : 1 ratio. The observation class added 3S2E manner in addition to ordinary breastfeeding, whereas the control class received treatment in the usual nursing mode. The two groups’ preintervention and postintervention times for mechanical ventilation, white blood cell count (WBC) recovery, duration of hospital stay, problems, respiratory function, psychological state, and living quality were compared. Results. Fever time abatement, mechanical ventilation time, WBC recovery time, and length of hospital stay in the observation category were found to be shorter in comparison with the control class (). In contrast to the other group, the observation group had fewer issues (). Both teams’ oxygenation indices and SaO₂ were higher after the intervention (), with the observation team’s index being higher than the control group’s index. The total SAS and SDS scores of the two groups were less in the postintervention period than in the preintervention period, with the observational class having lower postintervention SAS and SDS ratings than the comparison group (). The postintervention ratings in the observation class were higher than those in the control, and the World Health Organization Quality of Life (WHOQOL) scale scores in the 2 categories were greater after the intervention than they were before (). Conclusion. 3S2E nursing management model improves respiratory function, alleviates negative emotions, and improves living quality in ICU patients with severe pneumonia.

3S2E护理管理对ICU重症肺炎患者呼吸功能心理状况及生活质量的影响


客观的。本研究探讨3S2E护理管理模式对重症监护病房重症肺炎患者呼吸功能、心理状态、生活质量（ICU）的影响。方法。根据随机数字表，纳入2021年3月至2022年3月期间收治的82例ICU重症肺炎患者，按1：1的比例分配至对照组和观察组（各41例）。观察班在普通母乳喂养的基础上增加3S2E方式，对照组则按常规护理模式进行治疗。比较两组干预前后机械通气时间、白细胞计数(WBC)恢复情况、住院时间、问题情况、呼吸功能、心理状态及生活质量。结果。与对照组相比，观察组的退烧时间、机械通气时间、白细胞恢复时间和住院时间均较短（）。与其他组相比，观察组的问题较少（）。干预后两队的氧合指数和SaO ₂均较高（），观察组的指数高于对照组的指数。两组干预后的 SAS 和 SDS 总分均低于干预前，其中观察组干预后 SAS 和 SDS 评分低于对照组（）。观察组的干预后评分高于对照组，世界卫生组织生活质量（WHOQOL）2个类别的量表得分在干预后高于干预前（）。结论。 3S2E护理管理模式改善ICU重症肺炎患者呼吸功能、缓解负性情绪、提高生活质量。
