dc.description.abstractAmaç: İkili antiagregan (ASA+ Klopidogrel) ilaç kullanırken acil koroner bypas cerrahisi uygulanan hastalarda kanama önemli bir morbidite sebebidir. Bu klinik çalışmanın amacı sözkonusu hasta grubunda traneksamik asit ve desmopressin asetat kullanımının perioperatif hemostaz üzerine etkilerini incelemektir.Materyal ve metod: Çalışma prospektif, randomize ve çift kör bir klinik çalışma olarak planlandı. KTÜ Tıp Fakültesi Kalp Damar Cerrahisi Anabilim Dalında ikili antiagregan kullanmaktayken acil koroner bypass ameliyatı yapılan 54 hasta çalışmaya dahil edildi. Tx grubundaki hastalara (n=18) cilt insizyonuyla beraber sadece Traneksamik asit (10mg/kg 30dk+1mg/kg 10 h iv), Tx+Des grubundaki hastalara (n=16) aynı şekilde traneksamik asit ve heparinin protamin ile nötralizasyonu sonrasında desmopressin asetat (0.3 ?g/kg dozunda 20 dk iv), Des grubundaki hastalara (n=10) sadece desmopressin asetat (0.3 ?g/kg dozunda 20 dk iv) verildi. Kontrol grubuna ise (n=10) hiçbir ilaç verilmedi. Bütün hastaların cerrahi uygulamaları aynı standartlarda yapıldı. Gruplar çeşitli kanama ve transfüzyon parametreleri bakımından karşılaştırıldılar.Bulgular: Gruplar arasında risk faktörleri, Euroscore puanları, preoperatif hematolojik ölçümler, distal anastomoz sayıları, CPB ve Kros klemp süreleri bakımından anlamlı farklılık yoktu (p>0.05). Ortalama kapatma süreleri (Protamin ile heparin nötralizasyonundan sternum kapanana kadar geçen süre) Tx grubunda 33 dk, Tx+Des grubunda 32dk, Des grubunda 45 dk, Kontrol grubunda 48 dk idi (p< 0.016). Preoperatif, ameliyattan 1 gün önce (T1), İntraoperatif, protamin ile haparin nötralizasyonu sonrası (T2), Postoperatif, YBÜ'ne gelişin 6. saatinde (T3) ve Postoperatif, YBÜ'ne gelişin 30. saatinde (T4) zamanlarında kan alınarak vWF (%) ve PAP(ng/ml) değerleri ölçüldü, vWF değerleri açısından farklılık gözlenmedi (p>0.016). Ortalama PAP değerleri T1 ve T2 zamanlarında farklılık göstermiyordu. T3 zamanında Tx grubunda 191 iken kontrolde 167 (p< 0.016), Des grubunda 92 iken Tx+Des grubunda 101 olarak ölçüldü (p>0.016). T4 zamanında ise Tx grubunda 282 iken Kontrol grubunda 155 idi (p<0.016). Postoperatif toplam drenaj miktarları Tx grubunda 535 ml, Tx+Des grubunda 574 ml Des grubunda 1430 ml ve Kontrol grubunda 1767 ml olarak bulundu (p< 0,016). Ortalama kan ürünü kullanımı incelendiğinde Eritrosit süspansiyonu miktarı Tx grubunda 0,56 Ü, Tx+Des grubunda 0,42 Ü, Des grubunda 3,06 Ü ve Kontrol grubunda 4,09 Ü idi (p<0.016). Ortalama TDP miktarı Tx grubunda 0,11 Ü, Tx+Des grubunda 0 Ü, Des grubunda 2,30 Ü ve Kontrol grubunda 3,40 Ü olarak bulundu (p<0.016). Ortalama kan ürünü maliyetleri hesaplandığında Tx grubunda 66 TL, Tx+Des grubunda 44 TL, Des grubunda 479TL ve Kontrol grubunda 842 TL olarak bulundu (p< 0,016).Sonuç: İkili antiagregan ilaç kullanırken acil koroner bypass cerrahisi uygulanması gereken hastalarda Traneksamik asit kullanımı intraoperatif kapatma süresini kısaltmış, postoperatif drenaj miktarını, kan ürünü kullanımını ve maliyeti azaltmıştır. Desmopressin asetatın böyle bir etkisi gözlenmemiştir.
dc.description.abstractObjective: Bleeding is an important morbiditiy occasion that the patients who are operated emergency coronary bypass surgery that they are using dual antiplatelet drugs (ASA+ Klopidogrel ). The aim of this clinical study is to investigate the effects using tranexamic acid and desmopressin acetate on preoperative hemostasis in these patients.Methods: The study is planned as a prospective, randomised, double blind study. 54 patients who are using dual antiplatelet that they are operated emergency coronary bypass in the Department of Cardiovascular Surgery, KTU Medicine Faculty, were included. Tx group patients (n=18) received only tranexamic acid with skin incition (10 mg/kg, 30 min. + 1mg/kg, 10 h. iv); Tx+Des group patients (n=16) similarly received tranexamic acid and desmopresin asetate that neutralized with heparin protamine ( 0.3 µg/kg, in 20 min. iv infusion); Des group patients (n=10) only received desmopressin acetate (0.3 µg/kg, in 20 min. iv infusion). The control group (n=10) received nothing. All patients were operated under same surgical standards. Groups were compared with bleeding and transfusion parameters.Results: There was no statistical difference between groups in regards to risk factors, Euroscore points, preoperative hematalogical parameters, distal anastomosis numbers ,CPB and cross clamp times (p>0.05). The average closure time was 33 minutes in the Tx group; 32 minutes in the Tx+Des group; 45 minutes in the Des group and in the control group it was 48 minutes (p< 0.016). Preoperative, one day before operation (T1), intraoperative, after protamine and heparine neutralization (T2), postoperative in the 6 th hour that the patients came intensive care unit (T3) and postoperative in the 30 th hour that the patients came intensive care unit (T4) and these different times vWF (%) ve PAP (ng/ml) values were measured by getting blood from patients and no differences was observed in the vWF values (p>0.016). The average PAP parameters showed no difference between T1 and T2 times. While the difference between Tx group compared to Tx+Des and Des groups was statistically significant at T3 time Tx; 191ng/ml, Tx+Des;101 ng/ml, Des; 92 ng/ml, (p<0.016), the difference between the Tx and control group was not sigificant (p> 0.016). At T4, however, only the difference between the Tx and Control group was significant 282;155 ng/ml (p<0.016).The total amounts of postoperative drainage was found 535 ml for the Tx group; 574 ml for the Tx+Des group; 1430 ml for the Des group and 1767 ml in the control group (p< 0,016). The avarage of blood products was investigated that erytrocyte suspansion amount was found 0,56 U for the Tx group; 0,42 U for the Tx+Des group; 3,06 U for the Des group and 4,09 U in the control group (p< 0,016). Avarage Tdp amount was found 0,11 U for the Tx group; 0 U for the Tx+Des group; 2,30 U for the Des group and 3,40 U in the control group (p< 0,016). Avarage of blood products costs was found 66 TL for the Tx group; 44 TL for the Tx+Des group; 479 TL for the Des group and 842 TL in the control group (p< 0,016).Conclusions: The patients, who are operated emergency coronary bypass surgery while they are employing dual antiplatelet (ASA+Klopidogrel), using tranexamic acid shortened intraoperative closure time, decreased the postoperative drainage amounts, blood products using and cost. However, desmopressin acetate infusion has no effects like that.en_US
