"Ruang Lingkup dan Cara penelitian : Selama kehamilan, untuk memenuhi kebutuhan pertumbuhan janin yang optimal diperlukan adaptasi ibu. Salah satu di antaranya terjadi perubahan kadar hormon pertumbuhan plasenta (hPGH), diduga akan menyebabkan kadar glukosa dan asam amino ibu meningkat. Penelitian ini dilakukan untuk melihat perbedaan kadar glukosa dan asam amino ibu dan bayi dengan berat lahir rendah (BBLR) dan berat lahir normal (BBLN). Penelitian ini berupa studi eksploratif pada dua kelompok ibu hamil aterm (38 - 40 minggu). Kelompok I, 15 ibu hamil yang mempunyai taksiran berat janin antara 2000 - 2500 g. Kelompok II, ibu hamil yang mempunyai taksiran berat janin antara 2501 - 3500 g. Pengambilan percontoh darah dari vena kubiti ibu dan darah talipusat untuk pemeriksaan kadar glukosa dan asam amino total. Selain itu juga diukur berat plasenta. Dilakukan perbandingan nilai rata-rata antara dua kelompok dengan batas kemaknaan α = 5%.Hasil dan Kesimpulan : Kadar glukosa serum ibu kelompok BBLR = 112,4 mg/dl. Kelompok BBLN = 110,93 mg/dl. Kadar asam amino serum ibu kelompok BBLR = 5,62 mg/dl. Kelompok BBLN = 4,45 mg/dl. Kadar glukosa serum talipusat (bayi) kelompok BBLR = 97,13 mg/dl, kelompok BBLN = 107,33 mg/dl. Kadar asam amino serum talipusat kelompok BBLR = 6,33 mg/dl, kelompok BBLN = 4,79 mg/dl. Berat plasenta BBLR = 416,66 g. Berat plasenta BBLN = 483,33 g. Kadar glukosa dan asam amino ibu dan bayi dengan berat lahir rendah tidak berbeda dengan berat normal.

Serum Levels Of Glucose And Amino Acids Of Mothers And Babies Of Low Birth Weight And NormalScope and Method of Study : During pregnancy, the mother supplies all essential nutrients for fetal growth and development. Maternal adaptations occur to meet the need of optimal fetal growth. Metabolic function changes represent one of the remarkable maternal adaptations. Maternal serum levels of glucose and amino acids increase as a result of the increasing serum levels of human placenta growth hormone (hPGH). The purpose of this study was to compare the glucose and amino acids levels in the serum of mothers with low birth weight (LBW) and normal birth weight (NBW) babies and the cord blood serum of the LBW and NBW babies. The method used in this study was exploration on two pregnant women groups of 38 - 40 weeks of pregnancy. The first group consisted of 15 pregnant women with LBW babies (2000 - 2500 g), and the second group was a group of 15 pregnant women who have NBW babies (2501 - 3500 g). Placenta weight were also taken.

Result and Conclusion : The result of the study showed that, the mean serum glucose level of mothers with LBW babies was 112.4 mg/dl, while that of mothers with NBW babies was 110,93 mg/dl. The mean serum amino acids level of mothers with LBW babies was 5.62 mg/dl, and that of mothers with NBW was 4.45 mg/dl. The mean glucose value in placental cord of LBW babies was 97.13 mg/dl, while that of NBW babies was 107.33 mg/dl. While the mean serum amino acids levels of LBW babies were 6.33 mg/dl, and that of NEW babies was 4.79 mg/dl, The mean placenta weights of LBW babies was 416.66 g and that of NBW babies was 483.33 mg/dl. There was no significant difference in serum levels of glucose and amino acids in both low birth weight and normal."

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."

"Preterm low birth weight (PLBW) infants are more likely to die during the neonatal period and PLBW survivors face neurodevelopmental problems, respiratory problems, and congenital anomalies. It is said that the poor periodontal health of the pregnant woman is a potential risk factor of PLBW. This investigation aims to study the oral hygiene and gingival inflammation condition of 2nd and 3rd trimester of pregnancy women and relate to the putative periodontal pathogen bacteriae as the probable cause of PLBW. The plaque index (Pll), calculus index (CI), and bleeding on probing (BOP) of the subjects ofboth groups were measured and compared. Maternal infection during pregnancy has been demonstrated to perturb cytokines and hormone- regulated gestation because of the translocation of the infection. The level of gingival cervicular fluid prostaglandin E2 (PG E2), interleukin 1β (lL-1β), lL-6, tumor necrotizing factors a (TNF-a) are usually highly correlated with those in amnion fluid of pregnant women withoutbacterial vaginosis (BV) and with intact placental membrane. It is concluded that the periodontal health of pregnant women must be in good condition to prevent the risk of having PLBW still need to beanticipated due to the presence of the inflammation signs."

"Bayi berat lahir rendah (BBLR) merupakan salah satu faktor risiko yang mempunyai kontribusi terhadap kematian bayi khususnya pada masa perinatal. Defisiensi besi merupakan salah satu penyebab utama anemia dalam kehamilan dan risiko kejadian BBLR.

Penelitian dilakukan pada September - Desember 2015. Disain penelitian ini adalah kasus kontrol dengan subyek penelitian adalah ibu yang melahirkan di RSUD Kota Depok dan Bekasi. Jumlah sampel sebanyak 56 kasus ibu yang melahirkan bayi dengan berat <2500 gram dan 112 kontrol ibu yang melahirkan bayi >2500gram. Pengumpulan data dilakukan dengan wawancara terstmktur menggunakan kuesioner dan rekam medik. Data dianalisis dengan uji bivariat chi-square dan uji multivariat regresi logistik. Hasil penelitian menunjukkan ibu yang selama kehamilannya cukup mengkonsumsi tablet tambah darah sebesar 53% dan yang kurang sebesar 47%. Hasil sekunder dari penelitian ini menemukan keluhan mual berkenaan dengan konsumsi tablet tambah darah terjadi pada 13,0% responden. Ibu yang selama kehamilannya kurang mengkonsumsi tablet tambah darah berisiko 6,04 kali lebih tinggi melahirkan bayi berat lahir rendah (BBLR) dibanding ibu yang selama kehamilannya cukup mengkonsumsi tablet tambah darah setelah dikontrol variabel usia kehamilan, kadar hemoglobin saat melahirkan, berat badan sebelum hamil dan pemeriksaan antenatal. Kesimpulan dari penelitian ini adalah kecukupan konsumsi tablet tambah darah pada ibu hamil secara signifikan menurunkan risiko kejadian BBLR......Low birth weight (LBW) is one of the risk factors that contribute to infant mortality, especially in the perinatal period. Iron deficiency is a major cause of anemia in pregnancy and low birth weight. The puipose of this study is to evaluate the effect of deficiency of iron-folic acid tablet consumption during pregnancy to the risk of low birth weight (LBW). The study was conducted in September-December 2015. The design of this study was case-control study with subjects were women giving birth in Depok and Bekasi Regional Public Hospital. Samples were 56 cases are mothers who gave birth to babies weighing <2500 g and 112 controls, the mother who gave birth >2500gram. The data was collected using a structured interview questionnaires and medical records. The data was analyzed by using chi-square and multivariate logistic regression. The results showed mother who consume enough iron-folic tablet during pregnancy of 53% and less consuming of 47%. The secondary result found 13,0% respondent experience nausea in the matter of iro n-folic acid consumption. Mothers who less consuming iron-folic acid tablet during pregnancy have 6,04 times greater risk of having low birth weight (LBW) than mothers who consume enough iron-folic acid tablet during her pregnancy after controlled by gestational age, hemoglobin at delivery, pre-pregnancy weight, and antenatal care. Conclusion in this study is consumption of iron-folic acid during pregnancy significantly reduce the incidence of low birthweight infants."

"Penulisan karya ilmiah akhir ini bertujuan untuk mengaplikasikan teori Konservasi melalui pendekatan asuhan perkembangan dalam perawatan tiga bayi berat lahir rendah (BBLR) yang mengalami penundaan pemberian nutrisi enteral dini. Nutrisi enteral dini memfasilitasi adaptasi saluran cerna sehingga tercapai maturasi yang penting bagi penerimaan nutrisi enteral bayi selanjutnya. Penyebab penundaan pemberian nutrisi enteral dini pada BBLR ini adalah intoleransi minum dan perdarahan saluran cerna. Kebutuhan nutrisi BBLR tetap terpenuhi melalui pemberian secara parenteral. Adapun pendekatan asuhan perkembangan yang digunakan bertujuan agar energi yang dimiliki bayi dapat digunakan secara optimal untuk tumbuh dan berkembang melalui pencapaian konservasi, dalam hal ini konservasi energi. Selama menjalani perawatan, BBLR dalam uraian karya ilmiah akhir ini menunjukkan status oksigenasi yang baik, instabilitas suhu tidak terjadi, dan penurunan berat badan masih dalam kisaran rentang normal yaitu 10-15% dari berat badan lahir.

This scientific assignment aimed to applying the Conservation theory by approach of developmental care in nursing care of three cases of low birth weight (LBW) infants who experienced the delayed early enteral nutrition. Early enteral nutrition facilitated the adaptation of gastrointestinal tract in order to reach maturation which is important for LBW infants to receive enteral nutrition later. The causes of delayed early enteral nutrition in these LBW infants were feeding intolerance and gastrointestinal bleeding. Nutritional needs of these LBW infants was fulfilled by parenteral nutrition. The using of developmental care approach aimed to strive the energy of LBW infants could be optimally utilize for growth and development through attainment of energy conservation as one of conservation principles in Conservation theory. During treatments, LBW infants in this scientific assignment showed normal oxygenation status, stability of body temperature, and weight loss was still within normal range was 10-15% of birth weight."

"Angka kematian Bayi di Indonesia tahun 1999 masih merupakan masalah karena masih tinggi dibandingkan negara tetangga (40 / 1000 kelahiran hidup). Salah satu penyebab tingginya angka kematian bayi atau neonatal adalah berat badan bayi lahir rendah (BBLR). BBLR adalah bayi yang dilahirkan dengan berat badan lahir kurang dari 2500 gram yang mempunyai risiko tinggi dan harus mendapatkan pengawasan ketat dari dokter / perawat.Faktor risiko yang berhubungan dengan kejadian BBLR pada penelitian ini adalah umur, paritas, jarak kelahiran, umur kehamilan, status gizi, status sosial ekonomi dan layanan antenatal. Upaya yang di lakukan untuk menurunkan BBLR antara lain adalah dengan meningkatkan pelayanan antenatal, mengurangi faktor risiko BBLR, meningkatkan dan memperbanyak materi atau isi pelayanan antenatal.Tujuan penelitian ini adalah untuk mengetahui faktor risiko yang berhubungan dengan kejadian BBLR dalam konteks keperawatan maternitas di RSU PMI Kota Bogor. Metode penelitian yang digunakan adalah cross sectional dengan data primer. Sampel penelitian adalah semua ibu yang melahirkan bayi dengan berat badan lahir kurang dari 2500 gram selama periode Agustus - September 2002. Analisis data yang digunakan adalah melalui tiga tahap yaitu analisis univariat, bivariat dengan menggunakan uji Chi - Square dan mutivariat dengan menggunakan uji Regresi Logistik.Hasil penelitian pada analisis univariat dari variabel dependen menggambarkan bahwa kejadian BBLR di RSU PMI Kota Bogor tahun 2002 adalah 18,1 % dan variabel independen menggambarkan bahwa sebagian besar ibu umur 20 - 35 tahun (81,16 %), paritas 2 - 4 tahun (48,60 %), jarak kelahiran kurang dari 2 tahun (54,30 %), umur kehamilan lebih atau sama dengan 37 minggu (89,90 %), pendidikan SMU (48,60 %), pekerjaan IRT (81,90 %), penghasilan keluarga tinggi (66,70 %), tinggi badan lebih atau sama dengan 145 cm (95,65 %), penambahan BB lebih atau sama dengan 10 kg (63,77 %), kadar Hb lebih atau sama dengan 11 gr % (58,70 %), kuantitas ANC 1 - 3 kali (82,61 %) dan kualitas ANC lebih atau sama dengan 5 jenis pemeriksaan (88,40 %). Berdasarkan uji Chi - Square didapatkan bahwa dari kedua belas faktor yang diteliti ada sebagian kecil yang terbukti mempunyai hubungan bermakna terhadap kejadian BBLR yaitu umur ibu dengan nilai p = 0,023 dan odds ratio sebesar 3,176, umur kehamilan dengan nilai p = 0,0001 dan odds ratio sebesar 10,031 dan penambahan BB dengan nilai p = 0,012 dan odds ratio sebesar 3,343. Variabel yang masuk analisis multivariat adalah faktor umur ibu, umur kehamilan dan penambahan berat badan. Hasil analisis multivariat dengan uji regresi logistik ganda didapatkan hasil bahwa ada hubungan yang bermakna secara statistik antara umur ibu dengan nilai p = 0,016 dan odds ratio 3.966, umur kehamilan dengan nilai p = 0,0001 dan odds ratio 10,989 dan penambahan BB dengan nilai p = 0,024 dan odds ratio 3,118. Setelah dilakukan uji interaksi ternyata tidak ada interaksi antar variabel umur ibu, umur kehamilan dan penambahan BB.Kesimpulannya adalah bahwa faktor risiko yang paling berhubungan dengan kejadian BBLR adalah variabel umur kehamilan dengan nilai odds ratio sebesar 10,989 yang mempunyai arti bahwa umur kehamilan kurang dari 37 minggu akan terjadi risiko BBLR sekitar 11 kali lebih besar dibandingkan dengan umur kehamilan lebih dari 37 minggu sehingga disarankan kepada ibu untuk melahirkan anak pada usia kehamilan lebih atau sama dengan 37 minggu dan kepada para pemeriksa kehamilan supaya dapat menekankan pada setiap ibu hamil untuk memeriksakan kehamilannya secara teratur dan sesuai jadual pemeriksaan sehingga bila ada kelainan akan segera terdeteksi dan akan segera mendapatkan pertolongan.

The Analysis of Risk Factor That Relate To the Baby Who Has Low Weight in the Context of Maternities Nursery in PMI General Hospital, BogorThe infant mortality rate in Indonesia in 1999 still become problem for it was still high compare with neighbor countries (40/1000 alive birth). One of the causal factors of high infant mortality or neonates is the infant who has low weight in birth. The infant who has low weight in birth is the infant who was born with the weight less than 2500 gram and it has high risk and has to be cared intensively by the doctor/nurse.

In this study the risk factor that relation to the infant who has low weight in birth was the age, paritas, pregnancy range, the age of pregnancy, the condition of nutrient, social economic status and the antenatal service. The efforts to decrease the infant who has low weight in birth are done by increasing antenatal services, decrease the risk factor of the infant who has low weight in birth, increase and multiply the material or the content of the antenatal services.

The purpose of this study was to obtain the risk factors in relation to the infant who has low weight in birth in the context of maternity nursing in PMI general hospital, Bogor. The research method used was Cross Sectional, with primary data. The sample of research was all of mothers who delivered the infant with in the weight under 2500 gram in period August - September 2002. The data were analyzed by using 3 phases: univariat analysis, bivariat by using Chi - Square exam and multivariat used regression logistic exam.

The result of the study in univariat analysis of independent variable described that the infant who has low weight in birth in PMI general hospital, Bogor in 2002 showed 18, 1% and independent variable described that most of mothers in the age of 20 - 35 years old (81,16%), paritas 2 - 4 years old (48,60%), pregnancy range less than 2 years (54,30%) the age of pregnancy more or equal to 37 weeks (89,90 %), education : senior high school (48,60%), house wives (81,90%), income : high enough (66,70%), the height of body is more or equal to 145 an (95,65%), increasing the weight of body is more or equal to 10 kg (63,77%), hemoglobin is more or equal to 11 gr % (58,70%), the quantity of ANC is 1 - 3 times (82,61%) and the quality of ANC is more or equal to 5 kinds of examination (88,40%). Based on the exams of Chi - Square, it is found that among 12 factors that are researched, there is only small numbers can be proved have meaningful relationship to the infant who has low weight in birth i.e. the age mother with p = 0,023 and odds ratio 3,176 , the age of pregnancy with p = 0,0001 and odds ratio 10.031 and gaining weigh with p = 0,012 and odds ratio 3,343. Variable belongs is multivariat analysistis the factor of mother's age, the age of pregnancy and gaining the weight, The result of multivariant analysis together with double logistic regression exams will be found the result that shows that there is meaningful relationship in statistic way between the age of moth with p = 0,016 and odds ratio 3, 966, the age of pregnancy with p = 0.0001 and odds ratio 10,989 and gaining weight with p = 0,024 and odds ratio 3,118. After intersection examining, so we find that there is no interaction among the variable of mother's age, the age of pregnancy and gaining weight.

The conclusion is the risk factor that has the most relationship the infant who has low weight in birth is the variable of the pregnancy's age with the value of odds ratio 10,989 it has meaning that the pregnancy's age less than 37 weeks will have the risk of the infant who has low weight is birth about 11 times more than compare to the pregnancy's ages more 37 weeks, so it is advised to the mother to give a birth in the age of pregnancy more than or equal to 37 weeks, and those who examine the pregnancy should force to the every pregnant woman to examine her pregnancy regularly and follow the time schedule of examination, so that if there is improper of the pregnancy can be detected soon and can be helped soon."
