If neonatal sepsis is left untreated, it can greatly disrupt the child’s life. Treatment should be based on blood culture results and bacterial sensitivity tests, using antibiotics. Typically, a combination of a penicillin and an aminoglycoside antibiotic is chosen as the first-line medication. Since the patient has jaundice, blue light therapy should be administered. At the same time, attention should be paid to maintaining warmth, hydration and electrolyte balance, promptly correcting acidosis and dehydration, and treating local infection sites such as the umbilicus and skin.
