No mortality was seen in either group.Conclusion: Acute normovolemic hemodilution may preserve plasma levels of fibrinogen and reduce the need for allogeneic transfusion of blood products in patients with adequate preoperative fibrinogen level.

Objective & Hypothesis:Background: This study aims to investigate the effect of acute normovolemic hemodilution on reduced plasma levels of fibrinogen.Methods: We retrospectively evaluated data of a total of 101 adult patients (68 males, 33 females; mean age 61±8 years; range 46 to 84 years) who underwent elective coronary artery bypass grafting surgery between January 2014 and December 2015.
📊
Key Findings & Data:A comparison was made between patients who received acute normovolemic hemodilution (ANH group, n=49) and patients who did not (control group, n=52) matched by predictors of mortality and postoperative bleeding.Results: The mean decline in fibrinogen in ANH group (27.4±13.8%) was significantly lower, compared to the control group (43.7±9.5%, 95% CI: -21.4 to -11.3, p<0.0001).

Abstract

Background: This study aims to investigate the effect of acute normovolemic hemodilution on reduced plasma levels of fibrinogen.Methods: We retrospectively evaluated data of a total of 101 adult patients (68 males, 33 females; mean age 61±8 years; range 46 to 84 years) who underwent elective coronary artery bypass grafting surgery between January 2014 and December 2015. A comparison was made between patients who received acute normovolemic hemodilution (ANH group, n=49) and patients who did not (control group, n=52) matched by predictors of mortality and postoperative bleeding.Results: The mean decline in fibrinogen in ANH group (27.4±13.8%) was significantly lower, compared to the control group (43.7±9.5%, 95% CI: -21.4 to -11.3, p<0.0001). The mean decline in platelet count in ANH group (33.1±10.1) was similar to control group (35.6±8.9) (p=0.21). The whole blood was not re-transfused to 10 patients (20.4%) in ANH group at the end of surgery and preserved to be used in the intensive care unit. During intensive care unit stay, only eight patients (16.3%) in ANH group received allogeneic red blood cell, while 41 patients (78.8%) in the control group (p<0.0001). Only 14 patients (28.6%) in ANH group received allogeneic fresh frozen plasma, while all patients in the control group received (p<0.0001). No mortality was seen in either group.Conclusion: Acute normovolemic hemodilution may preserve plasma levels of fibrinogen and reduce the need for allogeneic transfusion of blood products in patients with adequate preoperative fibrinogen level.

Özet

Amaç: Bu çalışmada, akut normovolemik hemodilüsyonun, fibrinojen düzeylerindeki düşüşe etkisi araştırıldı. Çalış­ma­ planı:­ Ocak 2014 - Aralık 2015 tarihleri arasında elektif koroner arter baypas greftleme yapılan toplam 101 erişkin hastanın (68 erkek, 33 kadın; ort. yaş 61±8 yıl; dağılım 46-84 yıl) verileri retrospektif olarak incelendi. Akut normovolemik hemodilüsyon uygulanan hastalar (ANH grubu, n=49) ile uygulanmayan hastalar (kontrol grubu, n=52), mortalite ve ameliyat sonrası kanama belirteçlerine göre eşleştirilerek karşılaştırıldı. Bul­gular:­ Fibrinojen düzeyinde ortalama düşüş ANH grubunda (27.4±13.8%), kontrol grubuna kıyasla (43.7±9.5%) anlamlı düzeyde düşüktü (%95 GA: -21.4 ve -11.3, p<0.0001). Trombosit sayısında ortalama düşüş ANH grubunda (33.1±10.1), kontrol grubu ile (35.6±8.9) benzerdi (p=0.21). Cerrahi sonunda ANH grubunda 10 hastaya (%20.4) tam kan yeniden transfüze edilmedi ve yoğun bakım ünitesinde kullanılmak üzere saklandı. Yoğun bakım ünitesinde yatış sırasında, ANH grubunda sadece sekiz hastaya (%16.3) allojenik kırmızı kan hücre verilirken, kontrol grubunda 41 hastaya (%78.8) verildi (p<0.0001). ANH grubunda yalnızca 14 hastaya (%28.6) allojenik taze donmuş plazma verilirken, kontrol grubunda tüm hastalara verildi (p<0.0001). İki grupta da mortalite izlenmedi. Sonuç:­ Akut normovolemik hemodilüsyon, yeterli ameliyat öncesi fibrinojen düzeyine sahip hastalarda, plazma fibrinojen düzeylerini koruyabilir ve allojenik kan ürünü transfüzyonuna olan ihtiyacı azaltabilir.
