An exploratory study was designed to determine whether data made available by a pulmonary artery catheter or data obtained by nonivasive clinical evaluation were used as a basis for fluid management decisions in stable coronary artery bypass graft patients approximately 18 hours postoperatively and beyond. The sample consisted of 40 fluid management decisions made on 33 patients. The data were collected on all of the factors that influenced the decision. In no instance was information provided by the pulmonary artery catheter used as a basis for a fluid management decision; only noninvasive clinical measures were influential. The study questions the prolonged use of this medical technology with its attendant cost and risk. Nurses' roles in managing technology are highlighted.
一项探索性研究旨在确定，肺动脉导管提供的数据或通过无创临床评估获得的数据，是否被用作术后约18小时及以后稳定的冠状动脉搭桥患者液体管理决策的依据。样本包括对33名患者做出的40项液体管理决策。收集了所有影响该决策的因素的数据。在任何情况下，肺动脉导管提供的信息都未被用作液体管理决策的依据；只有无创临床测量有影响。该研究对这种医疗技术的长期使用及其附带的成本和风险提出了质疑。强调了护士在管理技术方面的作用。
