Yenidoğanlarda Beslenme İntoleransı ve Gastroözofageal Reflü
Özet
Yenidoğan döneminde, özellikle prematüre bebeklerde beslenme intoleransı ve gastroözofageal reflü, yenidoğan yoğun bakım pratiğinde sık karşılaşılan ve klinik olarak birbirine karışabilen durumlardır. Gastrointestinal sistem immatüritesi; motilite koordinasyonunun yetersizliği, mukozal bariyer immatüritesi, mikrobiyota gelişimindeki gecikme ve enteral beslenmeye adaptasyon güçlüğü ile beslenme intoleransına zemin hazırlar. Gastroözofageal reflü ise yenidoğanlarda çoğu zaman fizyolojik olup prematürelerde daha sık gözlenir; ancak reflü varlığı tek başına hastalık anlamına gelmez. Kusma, regürjitasyon, gastrik rezidü artışı, irritabilite, apne ve bradikardi gibi bulgular özgül değildir ve objektif ölçümlerde reflü olayları ile semptomlar arasında her zaman zamansal veya nedensel ilişki gösterilememektedir. Bu nedenle tanısal yaklaşımda dikkatli klinik değerlendirme esastır; rutin gastrik rezidü izlemi ve gereksiz farmakolojik tedavilerden kaçınılmalıdır. Yönetimde temel yaklaşım, anne sütünün öncelenmesi, erken fakat kontrollü enteral beslenme, standardize beslenme protokolleri ve seçilmiş olgularda hedefe yönelik destekleyici uygulamalardır. Amaç, fizyolojik süreçleri hastalık gibi tedavi etmek yerine gerçek patolojiyi ayırt ederek güvenli beslenme ve gastrointestinal adaptasyonu desteklemektir.
During the neonatal period, particularly in preterm infants, feeding intolerance and gastroesophageal reflux are common conditions in neonatal intensive care practice and may clinically overlap. Gastrointestinal system immaturity predisposes to feeding intolerance through inadequate motility coordination, immature mucosal barrier function, delayed microbiota development, and difficulties in adaptation to enteral feeding. Gastroesophageal reflux is often physiological in neonates and is observed more frequently in preterm infants; however, the presence of reflux alone does not indicate disease. Findings such as vomiting, regurgitation, increased gastric residuals, irritability, apnea, and bradycardia are nonspecific, and objective measurements do not always demonstrate a temporal or causal relationship between reflux events and symptoms. Therefore, careful clinical assessment is essential in the diagnostic approach; routine gastric residual monitoring and unnecessary pharmacological treatments should be avoided. The main principles of management include prioritizing human milk, initiating early but controlled enteral feeding, using standardized feeding protocols, and applying targeted supportive interventions in selected cases. The aim is not to treat physiological processes as disease, but to distinguish true pathology and support safe feeding and gastrointestinal adaptation.
