"Latar belakang: Renjatan merupakan masalah utama di ruang emergensi dan rawat intensif anak. Resusitasi cairan pada renjatan hanya memberikan repons pada 50% pasien. Pemberian cairan yang berlebih akan meningkatkan morbiditas dan mortalitas. Indeks dinamis memiliki keterbatasan dalam memprediksi fluid responsiveness. Left Ventricular End Diastolic Volume Index (LVEDVI) belum banyak diteliti dan dapat mengatasi keterbatasan indeks dinamis.Tujuan: Mengidentifikasi peran LVEDVI sebagai prediktor fluid responsiveness terhadap pemberian cairan resusitasi pada anak dengan renjatan.Metode: Ini adalah penelitian uji diagnostik-potong lintang pada anak dengan renjatan di ruang emergensi dan rawat intensif anak RSUPN Cipto Mangunkusumo Juni hingga November 2018. Pengukuran LVEDVI dilakukan menggunakan USCOM dan dibandingkan dengan peningkatan isi sekuncup ≥15% setelah fluid challenge sebagai kriteria fluid responsive. Sampel dimasukkan ke dalam kelompok fluid responsive dan fluid nonresponsive.Hasil: Dari 40 subyek penelitian, didapatkan 60 sampel fluid challenge. Terdapat 31 sampel di kelompok fluid responsive dan 29 sampel di kelompok fluid nonresponsive. Tidak terdapat perbedaan bermakna rerata LVEDVI pada kedua kelompok (p=0,161). Nilai AUROC LVEDVI 40,9% pada titik potong 68,95 mL/m², dengan sensitivitas 45,16% dan spesifisitas 44,83%.Simpulan: Penelitian ini tidak dapat membuktikan LVEDVI dapat berperan sebagai prediktor fluid responsiveness.

Background: Shock is a major problem in the Pediatric Emergency and Intensive Care Unit. Fluid resuscitation for shock only provides response in 50% of patients. Excessive fluid administration will increase morbidity and mortality. Dynamic indexes have limitations in predicting fluid responsiveness. Left Ventricular End Diastolic Volume Index (LVEDVI) has not been widely studied and can overcome the limitations of dynamic indexes.Objective: To identify LVEDVI as a predictor of fluid responsiveness in children with shock.Method: This was a cross-sectional diagnostic study in children with shock in the emergency room and pediatric intensive care unit of Cipto Mangunkusumo Hospital RSUPN from June to November 2018. The LVEDVI measurements were performed using USCOM and compared with an increase in stroke volume ≥15% after fluid challenge as fluid responsiveness criteria. Sample then categorized into fluid responsive and fluid nonresponsive group.Results: Of 40 subjects, 60 fluid challenge samples were obtained. There were 31 samples in the fluid responsive group and 29 in the fluid nonresponsive group. There was no significant mean difference of LVEDVI in the two groups (p=0.161). The AUROC of LVEDVI is 40,9% with cut off value of 68,95mL/m². The sensitivity and specificity are 45,16% and 44,83% respectively.Conclusion: This study cannot prove LVEDVI can act as a predictor of fluid responsiveness."

"Latar belakang: Penilaian fluid responsiveness merupakan masalah dalam tatalaksana pasien, terutama pasien dengan penyakit kritis. Stroke volume variation (SVV) adalah parameter hemodinamik untuk menilai fluid responsiveness. Pengukuran SVV dapat dilakukan dengan USCOM, yang merupakan alat pemantauan hemodinamik non invasif berbasis ekokardiografi DopplerTujuan: Mengetahui nilai cut-off point (titik potong optimal) SVV dengan USCOM sebagai prediktor fluid responsiveness pada pasien yang bernapas spontan maupn dengan ventilasi mekanik.Metode: Penelitan dilaksanakan di Pediatric Intensive Care Unit (PICU) dan UGD (Unit Gawat Darurat). Penelitian ini merupakan uji diagnostik dengan menggunakan peningkatan stroke volume (SV) setelah challenge cairan ringer laktat 10 ml/kg berat badan selama 15 menit sebagai indek. Subyek penelitian baik yang bernapas spontan maupun dengan ventilasi mekanik. Peningkatan nilai SV ≥10% disebut responder dan < 10% disebut non responder. Pengukuran SV dengan USCOM dilakukan sebelum dan setelah challenge, dan pengukuran SVV dilakukan sebelum challenge cairan.Hasil: Sebanyak 73 pengukuran terhadap subyek di PICU dan UGD. Area under curve (AUC) untuk seluruh subyek adalah 85,6% (95% IK 77,1% - 94,1%), p < 0,05. Titik potong optimal SVV adalah 28,5%, dengan sensitivitas 81,8% dan spesisifitas 75,9%. AUC subyek ventilasi mekanik adalah 76,6% (95% IK 60,1%-93,1%), p < 0,05. Titik potong optimal SVV adalah 30%, dengan sensitivitas 72,7% dan spesisifitas 70%. AUC subyek dengan pernapasan spontan adalah 93,7% (95% IK 84,6% - 100%), p < 0,05. Titik potong optimal SVV 28,5%, dengan sensitivitas 90,9% dan spesisifitas 84,2%.Simpulan USCOM memilki validitas yang baik untuk menilai SVV baik pada pasien bernapas spontan maupun dengan ventilasi mekanik.

Background: Assessment of fluid responsiveness is a problem in the management of patients, particularly patients with critical illness. Stroke volume variation (SVV) is a hemodynamic parameter to assess fluid responsiveness. Measurement of SVV could be done by USCOM, which is a non-invasive hemodynamic monitoring tool based on Doppler echocardiography.Objective: To determine the optimal SVV cut-off point measured by USCOM as a predictor of fluid responsiveness in spontaneously breathing and mechanically ventilated patients.Methods: Research was conducted in the pediatric intensive care unit (PICU) and emergency room (ER). This study is a diagnostic test based on the increment of stroke volume (SV) after fluid challenge using Ringer's lactate 10 mL / kg body weight for 15 minutes as an index. The subjects are both spontaneously breathing and mechanically ventilated patients. Responders are those who experienced increment ≥10% from baseline SV, and non-responders are those who did not meet the criteria. Measurements of SV using USCOM were performed before and after fluid challenge, meanwhile SVV measurement was performed before fluid challenge.Results: A total of 73 measurements were performed at the PICU and ER. Area under the curve (AUC) for all subjects was 85.6% (95% CI 77.1% - 94.1%), p value <0.05. Optimal SVV cut-off point was 28.5%, with sensitivity of 81.8% and specificity 75.9%. In mechanically ventilated subgroup, the AUC was 76.6% (95% CI 60.1% -93.1%), p value <0.05. The optimal SVV cut-off point of this group was 30%, with sensitivity of 72.7% and specificity of 70%. Lastly, the AUC of subjects with spontaneous breathing was 93.7% (95% CI 84.6% - 100%), p value <0.05. The optimal SVV cut of point in this group was 28.5%, with sensitivity of 90.9% and specificity of 84.2%.Conclusion: USCOM is valid for assessing SVV as a fluid responsiveness predictor, in patients with spontaneous breathing and mechanical ventilation."
