Objective: We aimed to retrospectively evaluate perioperative blood loss and allogeneic blood transfusion in child and adolescent patients who were given different doses of tranexamic acid (TXA) for adolescent idiopathic scoliosis surgery between 2011 and 2018. Material and Methods: After obtaining hospital's ethic committee approval, retrospective data were evaluated from anesthesia and medical files. Results: Ninety patients were included in the study. Two groups were identified: Group I (n=49) received intravenous TXA with 10 mgkg-1 bolus dose and 1 mgkg-1h-1 maintenance. Group II (n=41) received 20 mgkg-1 bolus and 2 mgkg-1h-1 maintenance. Mean estimated blood loss (EBL) and EBL per body weight were higher in Group I than Group II (933.8±161.2 vs. 846.3±94.1 ml; p=0.019) and (21.2±10.3 vs. 14.7±8.8 mlkg-1; p=0.011). More patients in Group I were transfused packed red blood cell (28.6% vs. 17.0%, p=0.036; 2.0±0.9 vs. 1.6±0.7 U; p=0.041) and fresh frozen plasma than Group II (12.2% vs. 7.3%; p=0.021, 1.6±0. vs. 1.0±0.4 U; p=0.033). Four patients in Group I and 3 in Group II (p=0.101) were admitted in the intensive care unit (ICU) for 12.0±3.3 hours. Major complications were not observed. Hospital discharge time was similar (3.5±1.2 vs. 3.2±0.9 days; p=0.801). Conclusion: A bolus TXA dose of 20 mgkg-1 and 2 mlkg-1h-1 maintenance was more effective in reducing blood loss and blood transfusion compared to a bolus dose of 10 mgkg-1 and 1 mlkg- 1h-1 maintenance. ICU admission rate, complications, and discharge time were similar between groups.

Amaç: Bu çalışmanın amacı 2011 ve 2018 yılları arasında adölesan idiopatik skolyoz cerrahisi uygulanan çocuk ve adölesan hastalarda farklı dozlarda traneksamik asit (TXA) uygulanmasının perioperatif kanama miktarı ve kan transfüzyonu üzerine etkisinin geriye dönük olarak incelenmesidir. Gereç ve Yöntemler: Hastane etik komite onayının alınmasını takiben, hastane veri tabanı, anestezi kayıtları ve hasta dosyaları incelendi. Bulgular: Çalışmaya 90 hasta dahil oldu ve iki grup tanımlandı: Grup I (n=49)'e intravenöz TXA 10 mgkg-1 bolus ve 1 mgkg-1sa-1 idame dozlarında, Grup II (n=41)'ye ise 20 mgkg-1 bolus ve 2 mgkg-1sa-1 idame dozlarında uygulanmıştı. Rtalama tahmini kan kaybı (ml) ve vücut ağırlığına göre kan kaybı (mlkg-1) Grup I'de Grup II'den fazlaydı. (933,8±161,2'ye karşı 846,3±94,1 ml; p=0,019) ve (21,2±10,3'e karşı 14,7±8,8 mlkg-1; p=0,011). Eritrosit süspansiyonu ve taze donmuş plazma transfüzyonu uygulanan hasta sayısı ve miktarı Grup I'de Grup II'den fazlaydı (%28,6'ya karşı %17,0; p=0,036 ve 2,0±0,9'a karşı 1,6±0,7 ünite; p=0,041); (%12,2'e karşı %7,3; p=0,021 ve 1,6±0,5'e karşı 1,0±0,4 ünite; p=0,033). Grup I'den 4 ve Grup II'den 3 hasta (p=0,101) yoğun bakım ünitesinde (YBÜ) 12,0±3,3 saat takip edildiler. Önemli bir komplikasyon gözlenmedi. Hastaneden taburcu edilme süreleri her iki grup arasında benzerdi (3,5±1,2'e karşı 3,2±0,9 gün; p=0,801). Sonuç: TXA'in 20 mgkg-1 bolus ve 2 mlkg-1sa-1 idame dozlarında uygulanmasının 10 mgkg-1 bolus ve 1 mlkg-1sa-1 idame dozlarına kıyasla kanama miktarı ve kan ürünleri transfüzyonu uygulanmasının azaltılmasında daha etkilidir. YBÜ'ne hasta alınma oranı, komplikasyonlar ve hastaneden taburcu edilme süreleri bakımından gruplar arasında farklılık gözlenmemiştir.
