摘要Background Objective To summarize the nursing experience of 9 cases of double-hole thoracoscopic aortic valve replacement.Methods From February 2021 to February 2022,9 patientsdiagnosed with severe aortic valve disease were enrolled,including 6 males and 3 females,with an average age(50.89±5.3)years,all of whom used double-hole thoracoscopic aortic valve replacement.Implement targeted surgical nursing plans,strengthen condition monitoring,surgical nursing cooperation,and take effective nursing interventions to urgently respond to intraopera-tive complications.Results Among the 9 patients,7 patients underwent mechanical valve replacement and 2 patients underwent biovalve replacement,of which 2 patients underwent aortic root enlargement surgery at the same time,and none of the patients underwent intraoperative emergency transfer orthothoracotomy.The extracorporeal bypass time was(137.56±27.99)min,the aortic occlusion time was(95.33±17.96)min,and the surgical survival rate was 100％;All patients had well-placed aortic valves,and 2 had mild(＜2 cm2)perivalvular leakage.The postoperative recovery time was short,the ventilation time was 6.13(4.43,19.99)h,of which 8 patients were extubated within 24 hours,and the ICU length of stay was(2.68±1.3)days,and no deaths and complications occurred.Conclusion For patients with simple aortic valve disease,double-hole thoracoscopic aortic valve replacement is a safe and effec-tive surgical treatment with good early clinical results.Implement a scientifically based nursing plan during surgery to effectively prevent complications,promote early recovery,and improve the quality of nursing.[S Chin J Cardi-ol 2023;23(2):85-90]
