Transient Tachypnea of the Newborn Medication
- Author: KN Siva Subramanian, MD; Chief Editor: Ted Rosenkrantz, MD more...
Medication Summary
The use of medications in transient tachypnea of the newborn (TTN) is minimal. Empiric antibiotics are often used for 48 hours after birth, until sepsis has been ruled out. Diuretics have not been shown to be beneficial.
Antibiotics
Class Summary
These agents are used when sepsis is clinically suggested. Antibiotics generally consist of a penicillin (usually ampicillin) and an aminoglycoside (usually gentamicin). Choices are based on local flora and antibiotic sensitivities. Dosage amounts and intervals are based on postmenstrual age (PMA), measured in weeks, and postnatal age, measured in days.
Ampicillin (Omnipen-N)
A penicillin antibiotic with activity against gram-positive and some gram-negative bacteria. Ampicillin binds to penicillin-binding proteins (PBPs), inhibiting bacterial cell wall growth.
Gentamicin
Provides gram-negative aerobic coverage. Gentamicin also provides synergistic activity with penicillins against gram-positive bacteria including group B Streptococcus and Enterococcus. Gentamicin inhibits protein synthesis by irreversibly binding to bacterial 30S and 50S ribosomes.
Given as IV infusion by syringe pump over 30 min. Administer as separate infusion from penicillin-containing compounds.
IM injection is associated with variable absorption, especially in VLBW infants.
