Korelasi antara Doppler-Based Renal Resistive Index dan Nilai Kreatinin pada Pasien Sakit Kritis
Dedi Tanto, Erwin Pradian, Erias Erlangga
Abstract
Indeks resistriksi renal/renal resistive index (RRI) merupakan pemeriksaan ultrasonografi non invasif untuk menilai renovascular dan dapat dilakukan dengan prinsip point-of-care testing (POCT) RRI merefleksikan perubahan aliran darah arteri intrarenalis, yang dapat terganggu pada pasien dengan gangguan fungsi ginjal, yang tercermin dalam peningkatan nilai kreatinin serum. Penelitian ini bersifat observasional analitik dengan desain potong lintang, bertujuan untuk mengetahui hubungan antara RRI dan nilai kreatinin serum pada pasien sakit kritis di ICU RSUP Dr. Hasan Sadikin, Bandung, dari Mei hingga Agustus 2023. Sebanyak 51 pasien berusia 18–65 tahun menjalani pemeriksaan RRI dan kreatinin serum pada 24 jam pertama dan kedua setelah masuk ICU. Analisis korelasi menunjukkan nilai R sebesar 0,538, koefisien determinasi (r²) sebesar 0,298, dan nilai p<0,001. Hasil ini menunjukkan korelasi positif moderat antara RRI dan nilai kreatinin serum.
