前馈控制管理在Stanford B型主动脉夹层患者急诊转运中的作用

The role of feedforward control management in emergency transport of patients with Stanford B aortic dissection

目的 探讨前馈控制管理在Stanford B型主动脉夹层患者急诊院内转运中的应用效果,为急诊危重症患者转运风险管理提供参考依据。方法 选取2021年2—11月天津市某三级甲等医院急诊院内转运的Stanford B型主动脉夹层患者102例为研究对象,将2021年2—6月51例Stanford B型主动脉夹层急诊院内转运患者设为对照组,实施常规转运流程;2021年7—11月51例Stanford B型主动脉夹层急诊院内转运患者设为观察组,基于前馈控制理论对患者疾病、护理人员、仪器设备、组织管理4项潜在高危因素实施超前管理。比较两组患者疼痛缓解率、心率控制达标率、血压控制达标率、转运前准备总耗时、转运过程总耗时、交接过程总耗时。结果 观察组疼痛缓解率、心率控制达标率、血压控制达标率均高于对照组(P<0.05),观察组转运前准备总耗时、转运过程总耗时、交接过程总耗时均短于对照组(P<0.05)。结论 前馈控制管理应用于Stanford B型主动脉夹层患者,可提高患者转运安全,缩短转运时长,减少转运安全隐患的发生。

Objective To explore the application effect of feedforward control management in emergency hospital transport of patients with Stanford B aortic dissection, and provide reference for transport risk management of emergency critical patients. Methods We selected 102 patients with Stanford type B aortic dissection who were transferred in the emergency hospital of a Grade III A hospital in Tianjin as the study subjects from February to November 2021. A total of 51 patients with Stanford B aortic dissection who were transferred in emergency hospital were set as a control group from February to June 2021, and the routine transfer process was implemented;another 51 patients with Stanford B aortic dissection who were transferred in emergency hospital were set as an observation group From July to November 2021, based on the feedforward control theory, advance management was carried out on the four potential high-risk factors of patients’ disease, nursing staf f, equipment and organization management. The pain relief rate, the rate of reaching the standard of heart rate control, the rate of reaching the standard of blood pressure control, the total time for preparation before transfer, the total time for transfer and the total time for handover were compared between the two groups. Results The pain relief rate, the rate of reaching the standard of heart rate control and the rate of reaching the standard of blood pressure control in the observation group were higher than those in the control group(P<0.05). The total time for preparation before transfer, the total time for transfer and the total time for handover in the observation group were shorter than those in the control group(P<0.05). Conclusion The application of feedforward control management in patients with Stanford B aortic dissection can improve the transport safety of patients, shorten the transport time, and reduce the occurrence of transport security risks.
