总结1例罕见左心室壁瘤胎儿要新生儿的围手术期护理体会。 针对胎儿期高风险、术前心功能不全及术后循环不稳定等情况，采取胎儿期紧密追踪，新生儿期术前改善心脏功能、防止血栓脱落、预防瘤体破裂，术后根据年龄特点设定目标血压、早期容量管理调节体液平衡、做好镇静镇痛管理以降低心肌耗氧量、阶段性护理干预促进心肺康复、严密观察预防并发症，出院阶段完善宣教和随访等措施。 患儿经过32 d精心护理后，病情稳定出院，出院后随访1个月余，患儿心功能恢复良好。

To summarize the fetal-neonatal perioperative nursing experience of a case of rare left ventricular aneurysm. In view of the high risk in the fetal period，preoperative cardiac insufficiency and postoperative circulatory instability，close follow-up in the fetal period was adopted，and we improved cardiac function，prevented thrombus shedding and tumor rupture before the operation in the neonatal period. We set target blood pressure according to age characteristics after the operation，regulated body fluid balance through early volume management， did a good job in sedation and analgesia management to reduce myocardial oxygen consumption，promoted cardiopulmonary rehabilitation through phased nursing intervention，and strictly observed and prevented complications. We improved the health education and follow-up measures at the discharge stage. After 32 days of intensive care，the patient was discharged from the hospital in a stable condition. After more than 1 month of follow-up after discharge，the patient’s cardiac function recovered well.
