"Peran NT-proBNP sebagai penanda biologis untuk mengetahui terjadinya sindrom curah jantung rendah pada pasien pediatrik dengan penyakit jantung bawaan sianotik pascabedah jantung terbuka belumlah diketahui. NT-proBNP diharapkan dapat menjadi penanda sindrom curah jantung rendah sehingga dapat mengurangi morbiditas dan mortalitas. Penelitian cross sectional ini melibatkan 40 pasien pediatrik dengan penyakit jantung bawaan sianotik yang menjalani pembedahan jantung terbuka di Rumah Sakit Jantung dan Pembuluh Darah Harapan Kita, selama bulan Maret 2019-April 2019. Terdapat perbedaan bermakna antara kadar NT-proBNP prabedah, 4 jam pascabedah, 24 jam pascabedah dan 72 jam pascabedah terhadap kejadian sindrom curah jantung rendah (p<0,001). Kadar NT-proBNP tertinggi pada 24 jam pasca bedah dengan perbedaan bermakna terhadap kadar NT-proBNP prabedah (p<0,001), 4 jam pascabedah dan 72 jam pascabedah (p<0,001). Diperoleh pula variabel lain yang berhubungan secara bermakna dengan NT-proBNP yaitu usia, berat badan, jenis penyakit jantung bawaan sianotik, lama aortic cross clamp, lama cardiopulmonary bypass, lama ventilasi mekanik dan lama rawat PICU. Dapat disimpulkan bahwa kadar NT-proBNP yang tinggi sebagai penanda kejadian sindrom curah jantung rendah.

The role of NT-proBNP as a biological marker to determined the occurrence of low cardiac output syndromes in pediatric patients with cyanotic congenital heart disease after open heart surgery was unknown. NT-proBNP was expected to be a marker of low cardiac output syndrome so that it can reduce morbidity and mortality. This cross-sectional study involved 40 pediatric patients with cyanotic congenital heart disease who underwent open heart surgery at National Cardiovascular Centre Harapan Kita, during March 2019-April 2019. There were significant differences between pre-operative levels of NT-proBNP, 4 hours postoperatively, 24 hours postoperatively and 72 hours postoperatively with the incidence of low cardiac output syndrome (p <0.001). The highest NT-proBNP level was 24 hours postoperatively with a significant difference in preoperative levels of NT-proBNP (p <0.001), 4 hours postoperatively and 72 hours postoperatively (p <0.001). Other variables that were significantly associated with NT-proBNP were age, body weight, type of cyanotic congenital heart disease, duration of aortic cross clamp, duration of cardiopulmonary bypass, duration of mechanical ventilation and length of stay of PICU. It can be concluded that high NT-proBNP level as a marker of low cardiac output syndrome."

"Latar belakang: Penyakit jantung bawaan merupakan jenis kelainan bawaan lahir paling umum, dan merupakan penyebab kematian tersering pada bayi. Sindrom curah jantung rendah masih merupakan masalah yang dihadapi pada subjek pediatrik pascaoperasi jantung terbuka. Deteksi sindrom curah jantung rendah dengan kriteria klinis dan indikator laboratorik masih dirasa belum cukup, yang terbukti dengan masih adanya angka morbiditas dan mortalitas. Peranan penanda biologis NT-proBNP diharapkan dapat digunakan untuk dapat mendeteksi sindrom curah jantung rendah pada pediatrik.Metode: Penelitian pendahuluan kohort retrospektif dengan jumlah 47 subjek yang memenuhi kriteria inklusi dan eksklusi yang menjalani pembedahan jantung terbuka paliatif; PA banding, Bidirectional cavopulmonary shunt, BT-shuntdan Fontan, pada periode Oktober 2019 hingga Maret 2020 di Rumah Sakit Jantung dan Pembuluh darah Nasional Harapan Kita, Indonesia. Data prabedah, intrabedah dan pascaoperasi termasuk kejadian sindrom curah jantung rendah dicatat. Kadar NT-proBNP akan diambil prabedah, 4 jam, 24 jam dan 72 jam pascaoperasi. Analisis data menggunakan uji Mann-Whitney. Hasil: Kadar NT-proBNP pada prosedur palitif khususnya Fontan pada prabedah (137 pg/ml), 4 jam pascaoperasi (685 pg/ml), 24 jam pascaoperasi (5.715 pg/ml), dan 72 jam pascaoperasi (970 pg/ml). Kadar NT-proBNP prabedah, 4 jam pascaoperasi, 24 jam pascaoperasi, dan 72 jam pascaoperasi tidak berbeda bermakna dengan kejadian sindrom curah jantung rendah (nilai p >0,05). Kesimpulan: Ditemukan peningkatan nilai NT-Pro BNP pada subjek pascaoperasi jantung paliatif khususnya Fontan dan bidirectional cavopulmonary shunt yang mengalami sindrom curah jantung rendah pada jam ke-24.

Background: Congenital heart disease is the most common type of birth defects, and is the most common cause of death in infants. Cardiac syndrome is still a problem faced by pediatric patients after heart surgery. Detection of Low Cardiac Output Syndrome with clinical criteria and laboratory indicators is still considered insufficient, which is proven to still contain morbidity and mortality rates. The role of NT-proBNP biological markers is expected to be used to support the detection of low cardiac output syndrome in pediatrics.

Methods: A Preliminary retrospective cohort with 47 subjects fulfilling the inclusion and exclusion criteria who underwent palliative open heart surgery PA banding, Bidirectional cavopulmonary shunt, BT-shunt and Fontan from October, 2019 to March, 2020 at the Harapan Kita National Heart and Vascular Hospital, Indonesia. Preoperative, operative and postoperative data including the incidence of low cardiac output syndrome were recorded. NT-proBNP levels will be taken pre-surgery, 4 hours, 24 hours and 72 hours after surgery. Data analysis using the Mann-Whitney test.

Results: NT-proBNP levels in the cardiac palliative surgery especially Fontan procedure at pre-surgery (137 pg/mL), 4 hours after surgery (685 pg/mL), 24 hours after surgery (5,715 pg/mL), and 72 hours after surgery (970 pg/mL). NT-proBNP levels at pre-surgery, 4 hours after surgery, 24 hours after surgery, and 72 hours after surgery were not significantly different from the incidence of low cardiac output syndrome (p value> 0.05).

Conclusion: There is an increase in NT-Pro BNP values ​​in subjects with Fontan palliative heart surgery and bidirectional cavopulmonary shunt. However, the above conclusions are still based on the number of samples with research powers<80% and can only be taken as a provisional conclusion based on preliminary studies."

ABSTRACTObjective : The benefits of the transatrial-transpulmonary (TA-TP) without transannularpatch (TAP) correction of tetralogy of Fallot (TOF) are preservation of pulmonary valveannulus and right ventricular function. However, TA-TP without TAP correction of TOFhad a higher incidence of low cardiac output syndrome (LCOS) because of the high rightventricle and pulmonary artery (RV-PA) pressure gradient and right ventricle and leftventricle pressure (pRV/LV) ratio. The purpose of this study were to analyze the cut offvalue of RV-PA pressure gradient dan pRV/LV ratio as the best predictor value forpostoperative LCOS in TA-TP without TAP correction of TOF.Methods : Between Oktober 2012 and Maret 2013, 30 patients with TOF underwent TATPwithout TAP correction (mean age 8,37±7,90 years, range 1-27 years). At the end ofcorrection, all patients underwent intraoperative direct measurement of RV-PA pressuregradient and pRV/LV ratio. The patients were evaluated for postoperative LCOS at theIntensive Care Unit (ICU). All the patients underwent echocardiographic examinationbefore hospital discharge. This included investigation of the presence RV-PA pressuregradien, RV function, residual VSD, pulmonary and tricuspid valve insufficiency.Results : Thirty patients with pulmonary valve annulus z-value ≥ -1, underwent TA-TPwithout TAP correction of TOF. Mean intraoperative RV-PA pressure gradient was21,13±10,60 mmHg and mean intraoperative pRV/LV ratio was 0,53±0,14. Mean RV-PApressure gradient measured 24 hours after correction at the ICU was 20,83±7,10 mmHgand mean pRV/LV ratio measured at 24 hours after correction at the ICU was 0,49±0,10.No patient had LCOS, we could not analyze the cut off value of RV-PA pressure gradientand pRV/LV ratio as the best predictor value for postoperative LCOS in this study. Nopatient had residual VSD. Mean RV-PA pressure gradient before hospital discharge was23,47±6,95 mmHg. Fifteen (50%) patients had mild pulmonary valve insufficiency and16 (53%) patients had trivial-mild tricuspid valve insufficiency. Three (10%) patients hadmild RV dysfunction. Postoperative mean TAPSE was 1,03±0,19. No patient hadarrhythmia, reoperation and mortality in this study.Conclusions : The TA-TP without TAP correction of TOF was applied successfully in 30patients with pulmonary valve annulus z-value ≥ -1, post-correction RV-PA pressuregradient < 25 mmHg and pRV/LV ratio < 0,5."

"Latarbelakang : Defek septum atrium sekundum (DSAS) adalah salah satu penyakit kongenital yang paling sering dijumpai pada pasien anak dan dewasa. Prevalensi DSAS sebanyak 80 kasus menurut database Bedah pediatrik dan kongenital PJNHK. Salah satu morbiditas pascaoperasi penutupan DSAS yaitu LCOS. LCOS akibat dari volume overload dari atrium-ventrikel kanan dan underload pada atrium-ventrikel kiri. Hal ini mengakibatkan ventrikel kiri akan lebih smallish dibandingkan ventrikel kanan. Kurangnya volume pengisian ke ventrikel kiri yang smallish menyebabkan gangguan fungsi diastolik kiri. Setelah dilakukan penutupan DSAS, aliran darah dari atrium kiri ke atrium kanan akan berhenti dan aliran darah dari atrium kiri ke ventrikel kiri akan meningkat. ventrikel kiri yang smallish akan menerima darah lebih banyak secara tiba-tiba sehingga dapat menyebabkan gagal sirkulasi. Maka dari itu penting untuk mengetahui ukuran volume ventrikel kiri sebelum dilakukan penutupan DSAS untuk menghindari LCOS. MRI merupakan pemeriksaan gold standar untuk mengukur volume ventrikel. Metode : Dilakukan studi kohort retrospektif pada pasien DSAS yang berumur >5 tahun yang memilikidata preoperasi MRI LVEDVi untuk menilai volume ventrikel kiri periode waktu Januari 2018-Desember 2019. Analisis bivariat menggunakan uji student t-test tidak berpasangan. Uji diagnostik menggunakan ROC untuk mendapatkan nilai AUC. Penentuan cut-off point berdasarkan nilai sensitivitas dan spesifisitas yang seimbang kemudian dinilai positive predictive value dan negatif predictive value. Hasil : Terdapat 62 subjek dari penelitian ini Subjek yang mengalami kejadian LCOS di ICU mempunyai rerata LVEDVi 45±7,42mL/m2. Subjek yang tidak mengalami kejadian LCOS rerata LVEDVi 64,15±13,37mL/m2 (p< 0,001). Nilai AUC 96% (95% CI: 92-100%). Nilai cut off LVEDVi terbaik terhadap kejadian LCOS pascaoperasi penutupan DSAS yaitu ≤53,3mL/m2. Memiliki sensitivitas 87,1%, spesifisitas 87,1%, positive predictive value 87,1%, negative predictive value 87,1% dan diagnostic accuracy 87,1%. Simpulan : LVEDVi terbukti dapat dijadikan prediktor kejadian LCOS pascaoperasi penutupan DSAS dengan titik potongyang baik.  Nilai cut off LVEDVi terbaik terhadap kejadian LCOS pascaoperasi penutupan DSAS yaitu 53,3mL/m2.

Background : SecundumAtrial Septal Defect (ASD) is one of the most common congenital diseases in pediatric and adult patients. The prevalence of secundum ASDis 80 cases according to the NCCHKPediatric and Congenital Surgery database. One of the postoperative morbidity of secundum ASDclosure is LCOS. LCOS results from volume overload from the right atrium-ventricle and underload in the left atrium-ventricle. This results in the left ventricle being smaller than the right ventricle. The lack of filling volume to the smallish left ventricle causes impaired left diastolic function. After secundum ASDclosure, blood flow from the left atrium to the right atrium will stop and blood flow from the left atrium to the left ventricle will increase. The smallish left ventricle will receive more blood suddenly so that it can cause circulation failure. Therefore it is important to know the size of the left ventricular volume before secundum ASDclosure to avoid LCOS. MRI is a gold standard examination to measure ventricular volume. Method : A retrospective cohort study was performed on secundum ASDpatients aged >5 years who had MRI LVEDVi preoperative data to assess the volume of the left ventricle during the January 2018-December 2019 period. Bivariate analysis usingan unpaired student t-testwas done. Diagnostic test uses ROC to get the AUC value. Determination of cut-off points was done based on balanced sensitivity and specificity values, after that we assesspositive predictive value and negative predictive value. Results : There were 62 subjects from this study. Subjects who experienced the occurrence of LCOS in the ICU had an average LVEDVi 45±7,42mL/m2. Subjects who did not experience an LCOShad an averageLVEDVi 64,15±13.37mL/m2 (p <0.001). AUC value of 96% (95%CI: 92-100%). The best LVEDVi cut off value for the incidence of LCOSpostoperative secundum ASDclosureis ≤53.3mL/m2.Ithas a sensitivity of 87,1%, specificity 87,1%, positive predictive value 87,1%, negative predictive value 87,1% and diagnostic accuracy 87,1%. Conclusion : LVEDVi is proven to be a predictor of the occurrence of LCOS events postoperative secundum ASDclosure with good cut points. The best LVEDVi cut off value for the occurrence of LCOS events postoperativesecundum ASDclosure is 53,3 mL/m2."

"Manuver rekrutmen paru (MRP) adalah strategi mencegah kerusakan paru saat bayi menggunakan ventilator mekanis (VM). Dengan meningkatkan tekanan akhir ekspirasi (TAE) secara bertahap, MRP membuka alveolus, menurunkan kebutuhan oksigen hirup (FiO2) sekaligus meningkatkan ambilan oksigen paru. Hingga kini, belum cukup bukti ilmiah terkait pengaruh MRP menggunakan VM terhadap luaran bayi prematur. Penelitian ini adalah uji klinis tidak tersamar, dilakukan di RS Cipto Mangunkusumo dan RSIA Bunda Menteng, bertujuan mencari hubungan MRP dengan kejadian DBP dan atau kematian, curah jantung, cedera alveolus-endotel, penurunan diameter duktus arteriosus (DA), dan mikrosirkulasi kulit. Penelitian berlangsung Maret 2021–April 2022. Subjek penelitian adalah bayi prematur 24–32 minggu yang menggunakan ventilator mekanis saat usia < 48 jam. Protein surfaktan-D (SP-D) diukur menggunakan metode ELISA, mikropartikel endotel (CD-31+/CD-42–) menggunakan flowsitometri, curah jantung dan diameter DA menggunakan ekokardiografi, TcCO2–PaCO2, TcO2/PaO2 menggunakan monitor gas darah transkutan dan gas darah arteri, strong ion difference (SID) menggunakan elektrolit darah arteri. Pada usia koreksi 36 minggu, tidak terdapat perbedaan bermakna kejadian DBP atau kematian antara kelompok MRP dan tanpa MRP 38 (69,09%) vs. 43 (78,18%), p = 0,216. Pada 72 jam pasca-penggunaan VM, tidak didapati perbedaan kadar SP-D, CD 31+, Diameter DA, curah jantung, TcCO2 gap dan SID antara kelompok MRP dan tanpa MRP . Terdapat perbedaan bermakna TcO2 indeks 1,00 (1,00; 1,02) vs. 1,00 (0,99; 1,00), p = 0,009* antara kelompok MRP dibanding tanpa MRP. Pada bayi penyintas, MRP mempercepat waktu untuk mencapai FiO2 ter-rendah 60,0 (54,00; 75,00) vs. 435,00 (375,00; 495,00) menit, p < 0,0001 dan lama penggunaan alat bantu napas 25,0 (19,00; 37,00) vs. 36,83 (SB 19,11) hari, p = 0,044.Simpulan, MRP bayi prematur tidak terbukti mengurangi kejadian DBP dan atau kematian pada usia 36 minggu. Tidak ada perbedaan cedera alveolar-endotel, curah jantung kiri-kanan, dan diameter DA pada usia 72 jam. Tindakan MRP meningkatkan mikrosirkulasi. Pada kelompok penyintas, MRP mempersingkat waktu mencapai FiO2 terendah dan penggunaan alat bantu napas.

Lung recruitment maneuver (LRM) is a strategy during mechanical ventilation which aim to open collapsed alveolus in order to increased oxygenation. This maneuver could be done by application of a stepwise increments of positive end expiratory pressure (PEEP) until lowest FiO2 (< 30%) is achieved. There is still lack of evidence regarding relationship between LRM and neonatal outcome. This study aimed to evaluate effectivity of LRM in order to reduce chronic lung disease and it’s influence to neonatal hemodynamic as well. This was unblinded randomized clinical trial which aimed to investigate relationship between LRM and neonatal death, bronchopulmonary dysplasia (BPD), cardiac output, reduction of ductus arteriosus (DA) diameter, skin microcirculations and alveolar-endotel injury. The study was conducted on March 2021 until April 2022 in Cipto Mangunkusumo and Bunda Menteng Hospital. Plasma surfactant protein-D (SP-D) was measured with ELISA, Microparticel endotel (CD-31+) with flowcytometri, left and right cardiac output (LVO and RVO) and DA diameter were measured by echocardiography, TcCO2–PaCO2, tcO2/PaO2 were measured form arterial blood gas and transcutaneous monitor and strong ion difference (SID) from plasma electrolyte. At 36 weeks follow up, there ware no significant difference of incident of DBP and/or death between MRP vs. without MRP groups 38 (69.09%) vs. 43 (78.18%), p = 0.216 (CI 95% 0.141–0.295). There were no difference between MRP and without MRP group at 72 hours, regarding : plasma SP-D, microparticle endotel, cardiac output, DA diameter, tcCO2 gap and SID. At. 72 hours, tcO2 index was better in MRP compared to control group 1.00 (1.00; 1.02) vs. 1.00 (0.99; 1.00), p = 0.009. There were no significant difference regarding other neonatal morbidity between the two group. Among survival subject, LRM reduced time to achieved lowest FiO2 60.00 (54.00; 75.00) vs. 435.00 (375.00; 495.00) hours, p < 0.0001 and length of respiratoy support 25.0 (19.00; 37.00) vs. 36.83 (SD 19.11) days, p=0.044.

Conclusion When applied to 24–32 weeks preterm baby with invasive mechanical ventilation, LRM could not reduced DBP or death at 36 weeks of age. There was no any difference at 72 hours regarding alveolar and endothelial injury, left and right cardiac output and diameter DA. LRM was associated with better microcirculation. Among the survivor, LRM reduced high oxygen concentration exposure time and length of respiratory support."

"Latar belakang: Penurunan curah jantung merupakan masalah yang penting dalam penatalaksanaan pasca-bedah jantung terbuka karena penurunan curah jantung ini meningkatkan morbiditas dan mortalitas pasien. Modalitas untuk pemantauan curah jantung bergeser dari invasif ke non-invasif. Alat ultrasonic cardiac output monitor (USCOM) dan ekokardiografi menjadi alat baru yang non-invasif. Bila dibandingkan dengan alat ekokardiografi yang membutuhkan keahlian khusus, alat USCOM dapat dijadikan alat pengukuran indeks curah jantung alternatif secara intermiten oleh tenaga medis terlatih.Tujuan: Untuk mengetahui kesesuaian hasil pengukuran indeks curah jantung dengan alat USCOM dibandingkan ekokardiografi pada anak pasca-bedah jantung terbuka dengan pintasan jantung paru.Metode: Studi potong lintang (cross sectional) pada anak pasca-bedah jantung terbuka dengan PJP dengan metode pengukuran simultan indeks curah jantung dengan alat USCOM dan ekokardiografi di Rumah Sakit Cipto Mangunkusumo, Jakarta, dari bulan Juni-Juli 2014.Hasil: Tiga belas pasien yang menjalani bedah jantung terbuka berhasil diukur dengan alat USCOM dan ekokardiografi secara simultan. Subyek terdiri atas 8 laki-laki dan 5 perempuan dengan median usia 3 tahun (1-12 tahun). Median berat badan, tinggi badan, dan luas permukaan tubuh berturut-turut 11 kg (5,5-29 kg), 82 cm (63-133 cm), dan 0,53 m2 (0,32- 0,98 m2). Diagnosis terbanyak berturut-turut adalah tetralogi Fallot (5 subyek), defek septum ventrikel (3 subyek), dan DORV (2 subyek).

"Panduan resusitasi anak umumnya menganjurkan pemberian cairan dalam jumlah besar. Beberapa penelitian memperlihatkan bahwa penggunaan cairan yang agresif meningkatkan mortalitas. Penelitian pada hewan menunjukkan tekanan vena sentral yang tinggi memicu pelepasan atrial natriuretic peptide ANP , sementara penelitian invitro memperlihatkan ANP meluruhkan glycocalyx endotel vaskular dan meningkatkan permeabilitas endotel. ANP juga memicu vasodilatasi. Hemodilusi berpotensi menurunkan pasokan oksigen tubuh DO2 . Penelitian bertujuan untuk melihat pengaruh resusitasi cairan terhadap kadar ANP serum, peluruhan glycocalyx endotel vaskular, extravascular lung water index ELWI , mean arterial pressure MAP , kadar hemoglobin dan pasokan oksigen. Hewan model renjatan adalah 11 ekor Sus scrofa jantan, usia 6-10 minggu. Renjatan dilakukan dengan metode fixed pressure hemorrhage. Resusitasi pertama dilakukan dengan jumlah cairan sesuai darah yang dikeluarkan resusitasi normovolemik , dilanjutkan dengan 40 mL/kg resusitasi hipervolemik . Pengukuran hemodinamik dilakukan dengan PICCO. Serum ANP dan Syndecan-1, petanda peluruhan glycocalyx, dilakukan dengan teknik ELISA. Hasil penelitian menunjukkan terjadinya peningkatan ANP pasca resusitasi normovolemik p = 0,043 , yang kemudian menurun kembali dalam 30 menit. Peluruhan glycocalyx tidak terjadi. Perbedaan ELWI pada 60 menit pasca resusitasi secara statistik bermakna, dengan perbedaan 0,93 mL/kg 95 IK:0,19 -3,62 . Terdapat korelasi kuat antara SVRI dan CI pasca resusitasi hipervolemik r = -0,587 . Tidak ada perbedaan MAP pasca resusitasi normovolemik dan hipervolemik. Kadar hemoglobin pasca resusitasi hipervolemik lebih rendah daripada pasca resusitasi normovolemik p = 0,009 . Pasokan oksigen tubuh pasca resusitasi hipervolemik lebih tinggi daripada pasca resusitasi normovolemik p = 0,012 . Simpulan: Resusitasi cairan pada renjatan akibat perdarahan tidak mengakibatkan peluruhan glycocalyx endotel vaskular. Peningkatan ELWI amat terbatas. SVRI berkorelasi terbalik dengan CI. Tidak ada perbedaan MAP antara resusitasi normovolemik dan hipervolemik. Resusitasi hipervolemik menyebabkan hemodilusi yang diimbangi dengan peningkatan curah jantung.

Many pediatric guidelines recommend liberal fluid resuscitation, but recent studies showed that aggressive fluid resuscitation might increase mortality. Animal studies showed that high central venous pressure induced ANP secretion. Invitro studies showed convincing evidence that ANP induced glycocalyx shedding. ANP also induced vasodilatation through cGMP signal transduction pathways. Hemodilution due to a large amount of resuscitation fluid potentially decreasing oxygen delivery.The objectives of this study were investigating the effect of fluid resuscitation, in the animal model, with special concern on serum ANP, glycocalyx shedding indicate by serum Syndecan-1 , changes in extravascular lung water, systemic vascular resirtance and mean arterial pressure, hemoglobin level and oxygen delivery DO2 . The animal models were 11 male domestic pigs, 6 -10 weeks old. The shock was induced with fixed pressure hemorrhage method. Fluid resuscitation was done in 2 phases. On the first attempt, we replaced total numbers of blood that withdrawn normovolemic resuscitation . On the second attempt, we gave 40 mL/kg resuscitation fluids hypervolemic resuscitation . The hemodynamic measurements were done with PICCO. Serum ANP and Syndecan-1 were measure with ELISA method.We found that serum ANP increased after normovolemic resuscitation p = 0.043 and immediately back to base level in 30 minutes. Glycocalyx shedding did not occur. Extravascular lung water index minimally increased. There was a strong correlation between SVRI and CI at hypervolemic resuscitation r = -0.587 . There was no difference in mean arterial pressure between normovolemic and hypervolemic resuscitation. Hemoglobin level after hypervolemic resuscitation was lower than after normovolemic resuscitation p = 0.009 . Oxygen delivery was higher after hypervolemic resuscitation p = 0.012 .Conclusions: Hypervolemic resuscitation in this hemorrhagic shock model did not induce glycocalyx shedding, extravascular lung water index minimally increased. Systemic vascular resistance index negatively correlated to cardiac index. Fluid resuscitation may induce hemodilution, but oxygen delivery can be compensated by increasing cardiac output. "

"Posisi tubuh semi fowler 30° lateral kanan yang dianggap upaya proteksi mandiri yang memiliki efek positif terhadap hemodinamik pada pasien gagal jantung, namun belum diketahui dampaknya terhadap curah jantung. Penelitian ini bertujuan untuk mengetahui pengaruh posisi semi fowler 30 lateral kanan terhadap curah jantung. Uji klinis crossover pada 20 subjek gagal jantung akut dengan teknik non randomisasi berdasarkan riwayat gagal jantung. Parameter hemodinamik diukur menggunakan alat LiDCO CNAP. Analisa dilakukan untuk menilai efek residual dan efektifitasnya menggunakan SPSS 26 & NCSS. Rentang usia subjek adalah 26-72 tahun. 75% tidak memiliki riwayat gagal jantung. 85% memiliki penurunan fraksi ejeksi ventrikel kiri <40%. Durasi washout 30 menit tidak menimbulkan efek residual dan tidak bermakna secara statistik (p>0.05). Perbedaan rerata stroke volume (p<0.05), variasi stroke volume 20.1±7.6 vs 43.3±19. Rerata curah jantung 4.88 sedangkan semi fowler 4.20, tidak signifikan secara statistik (p>0.05). Semi fowler 30 lateral kanan menurunkan variasi stroke volume dan meningkatkan rerata curah jantung. Dipertimbangkan sebagai strategi optimalisasi beban awal pada pasien gagal jantung preload dependent.

The right lateral semi fowler 30° body position is considered a self-protective measure that has a positive effect on hemodynamics in heart failure patients, but the impact on cardiac output is not yet known. This study aimed to determine the effect of positioning the right lateral 30 semi fowler on cardiac output. A non randomized Crossover clinical trial on 20 acute heart failure subjects based on history of heart failure. Hemodynamic parameters were measured using the LiDCO CNAP. Statistical analysis was performed to assess the residual effect and assess its effectiveness using SPSS 26 & NCSS software. The age range of subjects is 26-72 years. 75% had no history of heart failure. 85% of subjects had a decrease in left ventricular ejection fraction <40%. The washout duration of 30 minutes caused no residual effect and was not statistically significant (p>0.05). The average stroke volume differs significantly, stroke volume variation in SF30RL was 20.1±7.6 vs 43.3±19 in SF group. The mean cardiac output SF30RL was 4.88 while the semi fowler was 4.20 but not statistically significant (p>0.05). The right lateral 30 semi fowler can increase cardiac output values. Considered as a volume optimization strategy in a preload dependentt patients."
