In addition to fluid resuscitation and supportive care, a common antibiotic regimen in infants with suspected sepsis is a beta-lactam antibiotic (usually ampicillin) in combination with an aminoglycoside (usually gentamicin) or a third-generation cephalosporin (usually cefotaxime—ceftriaxone is generally avoided in neonates due to the ...
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.

Cefotaxime is an antibiotic used to treat several bacterial infections in humans, other animals, and plant tissue culture. [3] Specifically in humans it is used to treat joint infections , pelvic inflammatory disease , meningitis , pneumonia , urinary tract infections , sepsis , gonorrhea , and cellulitis . [ 3 ]
Ceftizoxime is a third-generation cephalosporin available for parenteral administration. [1] Unlike other third-generation cephalosporins, the whole C-3 side chain in ceftizoxime has been removed to prevent deactivation by hydrolytic enzymes.
In severe cases, cefotaxime and ceftriaxone delivered directly into the bloodstream are the elected antibiotics, and, for the less severe cases, an association of ampicillin and sulbactam, cephalosporins of the second and third generation, or fluoroquinolones are preferred.
Neonatal meningitis is a serious medical condition in infants that is rapidly fatal if untreated.Meningitis, an inflammation of the meninges, the protective membranes of the central nervous system, is more common in the neonatal period (infants less than 44 days old) than any other time in life, and is an important cause of morbidity and mortality globally.
Ampicillin/sulbactam should be given with caution in infants less than a week old and premature neonates. This is due to the underdeveloped urinary system in these patients, which can cause a significantly increased half-life for both drugs.16 Based on its elimination, ampicillin/sulbactam is typically given every 6 to 8 hours.
