目的 研究“三定”（定位、定责、定流程）急救模式在宫外孕大出血患者急诊抢救中的应用效果。方法 选取2021年1月—2023年5月期间收治的87例宫外孕大出血患者,根据护理方式不同分为常规组（n=45）和三定组（n=42）。常规组给予常规急诊护理模式干预,三定组给予“三定”急救模式干预。记录两组患者急救时效性评价指标、休克指数、急诊护理满意度,评价干预前后护士压力程度、急救医生满意度及护理人员技能评分,并进行统计学分析。结果 三定组抢救时间及总救护时间均短于常规组,总出血量低于常规组,差异具有统计学意义（P<0.05）;三定组干预后休克指数情况优于常规组,差异具有统计学意义（P<0.05）;三定组护理满意度为97.62%,高于常规组（82.22%）,差异具有统计学意义（P<0.05）;常规组护士压力程度得分高于三定组,急救医生满意度得分低三定组,差异具有统计学意义（P<0.05）;三定组护理人员个人基本能力、专业急救技能等各项技能较常规组均明显提升,差异具有统计学意义（P<0.05）。结论 对宫外孕大出血患者实施“三定”急救模式有助于提高医护人员急救效率,改善患者休克情况,降低护理人员急救压力,提高患者及急救医生满意度,临床上值得推广。

Objective To study the application effect of "three fixed" emergency mode in emergency rescue of patients with ectopic pregnancy and massive bleeding. Methods A total of 87 patients with ectopic pregnancy and massive bleeding admitted from January 2021 to May 2023 were selected and divided into a routine group （n=45） and a three fixed group （n=42）. The routine group received routine emergency nursing, while the three fixed group received “three fixed”emergency nursing.The evaluation indicators of emergency response timeliness, shock index, emergency nursing satisfaction of the two groups of patients were recorded, and the stress level of nurses before and after intervention, satisfaction of rescue medics, and skill scores of nursing staff were compared. Results The rescue time and total rescue and nursing time of the three fixed group were shorter than those of the routine group, and the total bleeding volume was lower （P<0.05）. The shock index of the three fixed group after intervention was significantly better than that of the routine group （P<0.05）. The nursing satisfaction of patients in the three fixed group was 97.62%, which was higher than 82.22% in the routine group （P<0.05）. The stress score of nurses in the routine group was higher than that in the three fixed group, while the satisfaction score of rescue medics was lower （P<0.05）. The basic abilities, professional first aid skills, and other skills of the nursing staff in the three fixed groups were significantly improved compared to the routine group（P<0.05）. Conclusion The implementation of the“three fixed” emergency mode for patients with ectopic pregnancy and massive bleeding can help improve the efficiency of medical staff's emergency response, relieve shock of patients, reduce the pressure of nursing staff on emergency response, and increase the satisfaction of patients and rescue medics, which is worthy of promotion.
