Latar belakang: Pada tahun 2016, Divisi Perinatologi RS dr. Cipto Mangunkusumo(RSCM) menerapkan panduan asuhan nutrisi terbaru untuk mencegah weight faltering,yang sangat rentan dialami bayi sangat prematur (<32 minggu) atau berat lahir sangatrendah (<1.500 gram). Penelitian ini bertujuan mengevaluasi luaran panduan tersebut.Metode: Penelitian kohort prospektif dilakukan di RSCM sejak Juli 2018 hingga Juni2019. Subyek merupakan bayi lahir hidup dengan usia gestasi <32 minggu atau berat lahir<1.500 gram. Bayi dengan kelainan metabolisme bawaan, kelainan genetik, ataumalformasi kongenital mayor dieksklusi. Data antropometrik mingguan dan komplikasi(enterokolitis nekrotikans, hipertrigliseridemia, kolestasis, dan sindrom refeeding) dicatatsecara berkala. Extrauterine growth restriction (EUGR) adalah berat badan saat pulangkurang dari persentil 10 kurva Fenton 2013 pada kelompok bayi yang lahir sesuai masakehamilan.Hasil: Sebanyak 111 subyek lahir dengan kesintasan hingga pulang sebesar 42,3% danmedian lama rawat 37 (8-89) hari. Median usia mulai diberi nutrisi enteral, mencapai fullenteral feeding, dan durasi nutrisi parenteral adalah 2, 9, dan 6 hari. Insidens EUGRadalah 32%. Rerata kenaikan berat badan pada bayi yang pulang adalah 15 (SB 5,4)g/kg/hari, dan pada bayi kecil masa kehamilan adalah 17 (SB 5,5) g/kg/hari. Insidenshipofosfatemia, enterokolitis nekrotikans, hipertrigliseridemia, hipokalemia, kolestasis,dan hipomagnesemia pada minggu pertama adalah 61,7%; 14,4%; 13,9%; 11,9%; 9,3%;dan 8,2%.Kesimpulan: Bayi sangat prematur dan berat lahir sangat rendah memiliki tingkatmortalitas yang tinggi, terutama pada kelompok ekstrem prematur dan ekstrem rendah.Panduan asuhan nutrisi terbaru dapat mencapai target kenaikan berat badan, dengankomplikasi terbanyak adalah hipofosfatemia.

Background and aim: In 2016, a nutritional care guideline was implemented in Cipto

Mangunkusumo Hospital to prevent weight faltering, which was prevalent in very preterm

(< 32 weeks) or very low birth weight/VLBW (<1,500 grams) infants. The objective of

this study was to evaluate its outcome.

Methods: This prospective cohort study was conducted in a national referral hospital

since July 2018 until June 2019. Subjects were live-born infants with gestational age <32

weeks or birth weight <1,500 grams. Infants with inborn errors of metabolism, genetic

abnormalities, and major congenital malformation were excluded. Weekly

anthropometric data and complications (necrotizing enterocolitis, hypertriglyceridemia,

cholestasis, and refeeding syndrome) were recorded. Extrauterine growth restriction

(EUGR) was defined as weight at discharge less than 10th percentile of Fenton 2013

chart.

Results: Among 111 subjects, the survival rate at discharge was 42.3% and median length

of stay was 37 (8-89) days. Median time to start enteral feeding, reach full enteral feeding,

and duration of total parenteral nutrition were 2, 9, and 6 days, respectively. EUGR

incidence at discharge was 32.1%. Mean weight gain among survivors and those who

were small-for-gestational-age were 15 (SD 5.4) and 17 (SD 5.5) g/kg/day, respectively.

The incidence of hypophosphatemia, necrotizing enterocolitis, hypertriglyceridemia,

hypokalemia, cholestasis, and hypomagnesemia were 61.7%, 14.4%, 13.9%, 11.9%,

9.3%, and 8.2%, respectively.

Conclusions: Very preterm and/or VLBW infants had high mortality rate, especially in

extremely preterm and/or extremely-low-birth-weight subgroup. The latest nutritional

care guideline reached the target weight gain. The most common complication was

hypophosphatemia.
