Yenidoğan Döneminde Akut Böbrek Yetmezliği: İnsidans, Risk Faktörleri Ve Prognoz

Year 2007, Volume: 1 Issue: 1, 11 - 17, 01.06.2007

Abstract

Amaç: Akut böbrek yetmezliği (ABY) böbrek fonksiyonlarının ani olarak bozulması sonucu sıvı- elektrolit ve asit-baz dengesinin yeterince sağlanamaması, kan basıncının iyi regüle edilememesi ve nitrojen yıkım ürünlerinin vücuttan atılamaması ile karakterize bir klinik tablo olup, yenidoğan yoğunbakım ünitelerinde (YYBÜ) prevalansı %6-11 olarak bildirilmektedir. Bu çalışmada YYBÜ' mizde yatırılarak izlenen yenidoğanlarda ABY gelişenler, ABY gelişiminde altta yatan risk faktörleri ve mortalitesinin belirlenmesi amaçlandı.Olgular ve Yöntem: Hastanemizde 2005 yılında yatırılarak izlenen yenidoğanlar retrospektif olarak değerlendirildi. Serum kreatinini >1,5 mg/dL bulunanlar ile serum üre değeri >55 mg/dL olup serum kreatinini günde 0,2 mg/dL' den fazla artanlar çalışmaya alındı.Bulgular: YYBÜ' mizde 2005 yılında yatan 1053 hastadan 84' ünde (% 7,98) ABY saptandı. Olguların kız/erkek oranı 30/54=0.56, ortalama doğum ağırlıkları 2896,1 ±100,2 gr (650-4820 g), yaşları 5,1±5 (0-27) gün olup 30' u (% 35,7) prematüreydi. Ortalama serum üre, kreatinin, sodyum, potasyum, ürik asit düzeyleri sırasıyla 99,2±60,3 (55-382) mg/dL, 1.24±1.02 (0,1-6,5) mg/dL, 144,5±13,1 (117-190) mEq/L, 5,2±1 (2,6-8,2) mEq/L ve 7,1±4,6 (0,4-22,5) mg/dL idi. Risk faktörleri ağırlık kaybı % 10' dan fazla olanlar (%10), aminoglikozid tedavisi (%51,2), diğer ilaç tedavileri (%52,4), sepsis (%26,2), mekanik ventilasyon uygulaması (%26,2), parenteral beslenme (%15,5), asfiksi (%9,5), nekrotizan enterokolit (%9,5) ve konjenital kalp hastalığı (KKH) (%8,3) idi. Olguların %77,4' ü prerenal azotemi, % 22.6' sı intrensek ABY tanısı aldı. Mortalite oranı %22,6, en sık mortalite nedenleri prematürite (%14,3), sepsis (%3,6), KKH (%2.49) ve perinatal asfiksiydi (%2,4). Mortaliteyi etkileyen faktörler prematürite, intrensek ABY ve mekanik ventilasyon uygulaması olarak saptandı (p<0.05).Sonuç: Akut Böbrek Yetmezliği morbidite ve mortalitesi yüksek bir hastalıktır. Şüpheli yenidoğanlar hızla değerlendirilmeli, gerekli tetkikler ile prerenal-intrensek-postrenal ayrımı yapılarak uygun tedavi gecikmeden başlanmalı, altta yatan risk faktörleri hızla belirlenerek mümkünse ortadan kaldırılmalıdır.

ACUTE RENAL FAILURE IN NEONATES: INCIDENCE, RISK FACTORS AND PROGNOSIS

Year 2007, Volume: 1 Issue: 1, 11 - 17, 01.06.2007

Abstract

Aim: Acute renal failure (ARF) is characterized by a sudden impairment in renal function, leading to inability of the kidneys to excrete nitrogenous waste. Acute renal failure is a frequent clinical condition in neonatal intensive care units (NICU), with a reported prevalence of 6-11%. In this study we aimed to define incidence of ARF among hospitalised neonates in our NICU, the risk factors related to ARF, and the outcome of the neonates with ARF treated in the NICU of our hospital.Method: A retrospective study was designed during 2005, to identify the neonates with ARF (serum creatinine level over 1.5 mg/dL, or urea over 55 mg/dL plus creatinine level increased over 0.2 mg/dL daily) in the NICU of our hospital.Results: There were 84 neonates (7.98%) with ARF among 1053 neonates hospitalized in our hospital neonatal intensive care unit with following characteristics: mean weight of 2896,1±100,2 gr (650-4820 g), postnatal ages of 5.1±5 days, female/male ratio of 30/54=0.56, prematurity ratio of 35,7% (n=30). The mean blood urea, creatinine, sodium, potasium and uric asit levels on admission were 99.2±60.3 mg/dL, 1.24±1.02 (0.1-6.5) mg/dL, 144.5±13.1 mEq/L, 5.2±1 (2.6- 8.2) mEq/L, and 7.1±4.6 (0.4-22.5) md/dL, respectively. Risk factors were as follows: dehydration over 10% (61,9%), aminoglycoside therapy (51,2%), other drugs (2,4%), sepsis (26,2%), mechanical ventilation (26,2%), parenteral nutrition (15,5%), asphyxia (9,5%), necrotising enterocolitis (9,5%), and congenital heart disease (8,3%). The ratios of prerenal azotemia and intrinsec ARF were 77,4%, and 22,6% respectively. Mortality ratio was 22,6% (n=19). Prematurity related disorders (n=12) and sepsis (n=3) were the most common reasons for exitus. We found significant relation between prematurity, intrensec ARF, mechanical ventilation and mortality.Conclusion: Acute renal failure is a frequent clinical condition in NICU’s characterized by significant morbidity and mortality. The suspected neonates should be evaluated as soon as possible, and differentiation of prerenal, renal, and postrenal ARF should be decided. Besides supportive initial treatment, physician should identify the underlying risk factors, which could be corrected

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
