Imbang Nitrogen dan Hubungannya dengan asupan energi dan protein pada usia lanjut usia kritis dalam 48 Jam Perawatan di ICU = Nitrogen Balance and Its relation with Energy and Protein Intake in Critically Ill Elderly Patients within 48 Hours in ICU.

Imbang nitrogen pada pasien sakit kritis selalu negatif akibat respon stres. Pada lansia perubahan metabolismenya berisiko memperburuk imbang nitrogen. Tujuan penelitian ini adalah untuk mengetahui imbang nitrogen dan hubungannya dengan asupan energi dan protein pada lansia sakit kritis dalam 48 jam pertama di ICU. Penelitian ini menggunakan metode potong lintang, consecutive sampling. Subyek penelitian adalah 26 lansia sakit kritis. Hasil penelitian pada 24 jam I dan II adalah; imbang nitrogen -5,2 (-31,2 − -4,1) g dan -4,5+4,6; asupan energi 78,8+45,0% dan 91,1+50,2% terhadap target; asupan protein 0,57+0,35 g/kgBB/hari dan 0,71+0,37 g/kgBB/hari serta terdapat korelasi positif bermakna antara imbang nitrogen dengan asupan energi; r=0,6 dan r=0,5 dan korelasi positif bermakna antara imbang nitrogen dengan asupan protein; r=0,5 dan r=0,4. Kesimpulan penelitian ini adalah terdapat hubungan bermakna antara imbang nitrogen dengan asupan energi dan protein pada lansia sakit kritis.

Nitrogen balance in criticaly ill patients tend to be negative due to stress response. In the elderly patients, the metabolic changes risk to worsening nitrogen balance.The aim of this study is to determine nitrogen balance and its relation with energy and protein intake in critically ill elderly patients within 48 hours in ICU. The study was cross sectional, consecutive sampling on 26 subjects. The nitrogen balances were -5.2 (-31.2 − -4.1) g and -4.5+4.6 g; energy intakes were 78.8+45.0% and 91.1+50.2% target; protein intakes were; 0.57+0.35 g/kgBW/d and 0.71+0.37 g/kgBW/d. There were positive correlation between nitrogen balance and energy intake; r=0.6 and r=0.5, and between nitrogen balance and protein intake; r=0.5 and r=0.4 in 24 hours I and II respectively. The conclusion is there were positive correlation between nitrogen balance with energy and protein intakes.
