Decreased cardiac output: an integrative review

ABSTRACT Objective: to identify, in the scientific literature, the defining characteristics and contributing factors (related factors, associated conditions and populations at risk) for nursing diagnosis decreased cardiac output. Method: an integrative literature review, conducted between September and October 2020, with an update in March 2022, in the MEDLINE via PubMed, LILACS, SciELO, CINAHL and EMBASE databases. Using acronym PEO, studies published in the last 10 years in Portuguese, English and Spanish were included. A descriptive analysis was carried out to present the elements mapped in the literature. Results: analysis of 31 articles identified different elements, highlighting 4 new related factors: hyperglycemic stress, prone position, left lateral position, sleep deprivation. Individuals with a history of cardiovascular disease and males were identified as possible populations at risk. Final considerations: the elements for decreased cardiac output, identified in the literature, add evidence that justifies the permanence of this diagnosis in the NANDA-I classification.

摘要 研究目的：旨在从科学文献中明确护理诊断"心输出量减少"的核心特征及相关影响因素（含相关危险因素、关联病症及高危人群）。研究方法：本研究为整合性文献综述，于2020年9月至10月开展，并于2022年3月进行更新，检索数据库涵盖MEDLINE（PubMed平台）、LILACS、SciELO、CINAHL及EMBASE。采用PEO缩略框架，纳入近10年以葡萄牙语、英语及西班牙语发表的相关研究。通过描述性分析对文献中梳理得到的要素进行呈现。研究结果：对31篇文献的分析共识别出多类相关要素，其中新增4项相关危险因素：高血糖应激、俯卧位、左侧卧位及睡眠剥夺。同时明确合并心血管疾病病史人群及男性为高危人群。研究结论：本次从文献中梳理得到的与心输出量减少相关的要素，可为该护理诊断保留在北美护理诊断协会（NANDA-I）分类体系中提供证据支撑。
