Latar belakang : Anemia akut sering terjadi pada anak sakit kritis yang dirawat diPICU, memiliki konsekuensi hipoksia global yang dapat mengakibatkan disfungsimiokardium. Transfusi PRC masih menjadi salah satu pilihan dalam rangkamemperbaiki oksigenasi dan kinerja jantung saat terjadi anemia. Bukti-bukti pengaruhtransfusi pada perbaikan performa jantung masih terbatas.Tujuan : Mengevaluasi kadar NT-proBNP, pasokan oksigen, indeks inotropi dan rasioenergi potensial:energi gerak pada jantung sebelum dan sesudah transfusi PRC padaanak sakit kritis yang mengalami anemia akut.Metode : Penelitian analitik observasional potong lintang sejak April sampai Agustus2019 pada anak usia 1 bulan-18 tahun dengan sakit kritis yang dirawat di PICURSUPN Dr. Cipto Mangunkusumo. Penilaian hemodinamik menggunakan USCOM.Hasil : Penelitian ini melibatkan 31 subyek dengan median umur 3,6 tahun (rentang0,1-17,5 tahun). Kadar Hb naik sebesar 29,1±15,9% setelah mendapat transfusi PRC9±3,3 mL/KgBB. Rerata kadar hemoglobin sebelum dan sesudah transfusi adalah7,94±1,46 dan 10,17±1,92 g/dL (p<0,000 IK 95%: 1,80-2,64). Kadar NT-proBNPmeningkat tak bermakna sebesar 12% (-77,0-199) setelah transfusi dari 4214±6678menjadi 5182±8327 pg/mL (p=0,186 IK 95%: -493-2428). Tidak terdapat korelasiantara persen perubahan Hb dan NT-proBNP (Spearman correlation r=0,124; p=0,505).Terdapat kenaikan pasokan oksigen pasca transfusi sebesar 20,7±38,9% dan berkorelasidengan kanaikan hemoglobin (Pearson correlation r=0,39; p=0,029). Uji Chi-squaremenunjukkan adanya hubungan bermakna antara kelompok yang mengalami kenaikanDO dengan perbaikan indeks inotropi (uji Chi square, p=0,031) dan perbaikan PKR(p=0,008), namun tak ada hubungan dengan perubahan NT-proBNP (p=0,511).Simpulan : Tidak terdapat perubahan bermakna kadar NT-proBNP sebelum dansesudah transfusi PRC pada anak sakit kritis yang mengalami anemia akut. Peningkatanpasokan oksigen pasca transfusi PRC berkorelasi dengan peningkatan indeks inotropi(Smith-Madigan Inotropy Index) dan perbaikan potensial to kinetic ratio (PKR)

Background: Acute anemia often occurs in critically ill children in PICU, which hasglobal hypoxic consequences resulting myocardial dysfunction. Transfusion of PRC isstill choosen in order to improve oxygenation and cardiac performance during anemia.Evidence of the effect of transfusion on improving cardiac performance is still limited.Objective: To evaluate NT-proBNP levels, delivery oxygen (DO2), inotropy index andthe potential to kinetic energy ratio (PKR) of heart before and after PRC transfusion incritically ill children with acute anemia.Methods: A cross-sectional observational analytic study conducted from April toAugust 2019 in children aged 1 month-18 years cared in PICU Dr. CiptoMangunkusumo Hospital. Hemodynamic assessment using USCOM.Results: This study involved 31 subjects with a median age of 3.6 years (range 0.1-17.5years). Hb levels increased by 29.1±15.9% after receiving a 9±3.3 mL / KgBBtransfusion PRC. The mean hemoglobin levels before and after the transfusion were7.94±1.46 and 10.17±1.92 g / dL (p <0.000; CI 95%: 1.80-2.64). NT-proBNP levelsslight increased but not statistically sgnificant by 12%(-77.0 - 199) after PRCtransfusion from 4214±6678 to 5182±8327 pg/mL (p = 0.186; CI 95%: -493 - 2428).There was no correlation between percent change in Hb and NT-proBNP (Spearmancorrelation r=0.124; p=0.505). There was increasing in DO2 after transfusion by20.7±38.9% and correlated with increased hemogolobin (Pearson correlation r=0.39;p=0.029). Chi-square test showed a significant relationship between groups thatexperienced an increase in DO2 with an improvement in the inotropy index (Chi squaretest, p=0.031) and improvement in PKR (p=0.008), but there was no relationship withNT-proBNP changes (p=0.511) .Conclusions: There was no significant change in NT-proBNP levels before and afterPRC transfusion in critically ill children who had acute anemia. Increased DO2 afterPRC transfusion correlates with an increase in the inotropy index (Smith-MadiganInotropy Index) and improvement in potential to kinetic ratio (PKR).
