Residual ventricular septal defect was also a risk factorfor major adverse events (odds ratio: 12.4, 95% confidence interval1.5-99.9, p=0.02).Conclusion: Preoperative and operative factors such as highpreoperative hematocrit, low preoperative oxygen saturation, lowpulmonary annulus Z-score, Down syndrome, residual ventricularseptal defects, and the use transannular patch were found to beassociated with prolonged length of hospital stay, prolongedmechanical ventilation, prolonged intensive care unit stay, andincreased development of major adverse events.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Background: In this study, we aimed to evaluate the patient andsurgical factors affecting prolonged hospital stay and major adverseevents after surgical repair of tetralogy of Fallot and to identify thepredictors of a complicated course after surgical repair.Methods: A total of 170 consecutive patients (96 males, 74 females;median age 12 months; range, 1 to 192 months) who underwentsurgical repair of tetralogy of Fallot between January 2015and April 2018 were retrospectively reviewed.
📊
Key Findings & Data:A mechanicalventilation duration of >24 h, an intensive care unit stay of >3 days,and a hospital stay of >7 days were considered as prolonged.Unplanned reoperation, complete heart block requiring apermanent pacemaker implantation, renal failure, diaphragmaticparalysis, neurological deficit, sudden circulatory arrest, need forextracorporeal membrane oxygenation, and death were consideredas major adverse events.Results: The median time to hospital discharge was 8.0(range, 5.0 to 40.0) days.
💡
Conclusion & Impact:Residual ventricular septal defect was also a risk factorfor major adverse events (odds ratio: 12.4, 95% confidence interval1.5-99.9, p=0.02).Conclusion: Preoperative and operative factors such as highpreoperative hematocrit, low preoperative oxygen saturation, lowpulmonary annulus Z-score, Down syndrome, residual ventricularseptal defects, and the use transannular patch were found to beassociated with prolonged length of hospital stay, prolongedmechanical ventilation, prolonged intensive care unit stay, andincreased development of major adverse events.

Abstract

Background: In this study, we aimed to evaluate the patient andsurgical factors affecting prolonged hospital stay and major adverseevents after surgical repair of tetralogy of Fallot and to identify thepredictors of a complicated course after surgical repair.Methods: A total of 170 consecutive patients (96 males, 74 females;median age 12 months; range, 1 to 192 months) who underwentsurgical repair of tetralogy of Fallot between January 2015and April 2018 were retrospectively reviewed. A mechanicalventilation duration of >24 h, an intensive care unit stay of >3 days,and a hospital stay of >7 days were considered as prolonged.Unplanned reoperation, complete heart block requiring apermanent pacemaker implantation, renal failure, diaphragmaticparalysis, neurological deficit, sudden circulatory arrest, need forextracorporeal membrane oxygenation, and death were consideredas major adverse events.Results: The median time to hospital discharge was 8.0(range, 5.0 to 40.0) days. Higher preoperative hematocrit levelsprolonged the length of hospital stay (odds ratio: 1.12, 95%confidence interval 1.1-1.2, p<0.001). A total of 28 major adverseevents were observed in 17 patients (10%). Lower pulmonary arteryannulus Z-score (odds ratio: 0.5, 95% confidence interval 0.3-0.9,p=0.01) and residual ventricular septal defects (odds ratio: 54.6, 95%confidence interval 1.6-1,874.2, p=0.03) were found to increasemortality. Residual ventricular septal defect was also a risk factorfor major adverse events (odds ratio: 12.4, 95% confidence interval1.5-99.9, p=0.02).Conclusion: Preoperative and operative factors such as highpreoperative hematocrit, low preoperative oxygen saturation, lowpulmonary annulus Z-score, Down syndrome, residual ventricularseptal defects, and the use transannular patch were found to beassociated with prolonged length of hospital stay, prolongedmechanical ventilation, prolonged intensive care unit stay, andincreased development of major adverse events.

Özet

Amaç: Bu çalışmada Fallot tetralojisinin cerrahi onarımından sonra hastanede uzayan kalış süresini ve majör advers olayları etkileyen hasta ve cerrahi faktörler değerlendirildi ve cerrahi onarım sonrasında komplike seyrin öngördürücüleri belirlendi. Ça­lış­ma pla­nı: Ocak 2015-Nisan 2018 tarihleri arasında Fallot tetralojisinin cerrahi onarımı yapılan toplam 170 ardışık hasta (96 erkek, 74 kız; medyan yaş 12 ay; dağılım, 1-192 ay) retrospektif olarak incelendi. Yirmi dört saatten fazla mekanik ventilasyon süresi, >3 günlük yoğun bakım ünitesinde kalış ve >7 günlük hastanede kalış süresi uzamış olarak kabul edildi. Planlanmamış tekrar ameliyat, kalıcı kalp pili takılmasını gerektiren tam kalp bloku, böbrek yetmezliği, diyafram paralizisi, nörolojik defisit, ani dolaşım arresti, ekstrakorporeal membran oksijenasyon gereksinimi ve ölüm majör advers olaylar olarak kabul edildi. Bulgular: Medyan hastaneden taburculuk süresi 8.0 (dağılım, 5.0-40.0) gün idi. Ameliyat öncesi yüksek hematokrit düzeyleri, hastanede kalış süresini uzattı (olasılık oranı: 1.12, %95 güven aralığı 1.1-1.2, p<0.001). On yedi hastada (%10) toplam 28 majör advers olay gözlendi. Alt pulmoner arter anülüs Z skoru (olasılık oranı: 0.5, %95 güven aralığı 0.3-09, p=0.01) ve rezidüel ventriküler septal defektlerin (olasılık oranı: 54.6, %95 güven aralığı 1.6-1874.2, p=0.03) mortaliteyi artırdığı tespit edildi. Rezidüel ventriküler septal defekt de, majör advers olay açısından bir risk faktörü idi (olasılık oranı: 12.4, %95 güven aralığı 1.5-99.9, p=0.02). So­nuç: Ameliyat öncesi yüksek hematokrit, ameliyat öncesi düşük oksijen satürasyonu, alt pulmonar anulüs Z skoru, Down sendromu, rezidüel ventriküler septal defektler ve transannüler yama kullanımı gibi ameliyat öncesi ve ameliyat sırası faktörler, hastanede kalış süresinde uzama, mekanik ventilasyonda uzama, yoğun bakım ünitesinde kalış süresinde uzama ve majör advers olay gelişiminde artış ile ilişkili bulundu.
