Different antibiotic strategies in transient tachypnea of the newborn: an ambispective cohort study.

UNLABELLED

The purpose of this study is to determine the outcome and infection-related events in neonates with transient tachypnea of the newborn (TTN) managed with an antibiotic initiation strategy. An ambispective cohort study was carried out to compare two different antibiotic strategies in of TTN patients. The first strategy is based on clinical risk evaluation, in which antibiotics are initiated according to clinical signs, while the other is a combined strategy that integrates information regarding clinical signs, perinatal risk factors, and lab-based surveillance of infectious indicators. The antibiotic use in the combined strategy group (n = 716) was lower than that of the control group (n = 769) (35.06 vs 54.75 %, P < 0.01). Outcomes including total duration of antibiotic therapy (5.45 ± 4.17 vs 5.18 ± 3.45 days, P = 0.36), mortality (0 vs 0), length of hospital stay (7.78 ± 4.20 vs 8.14 ± 3.62 days, P = 0.07), and hospital readmission (4.89 vs 4.94 %, P = 0.94) did not differ; nor did infection-related events such as nosocomial infection (2.93 vs 2.99 %, P = 0.95), infectious pneumonia (18.30 vs 19.90 %, P = 0.43), septicemia (1.96 vs 1.95 %, P = 0.99), and necrotizing enterocolitis (0.14 vs 0.26 %).

CONCLUSION

The combined strategy effectively reduces antibiotic usage during incidences of TTN with no negative impact on the clinical outcome.

WHAT IS KNOWN

• TTN is easy to be confused with infection only based on clinical signs. • Many TTN patients had been treated with unnecessary antibiotics.

WHAT IS NEW

• Our combined strategy for TTN can reduce antibiotics usage. • New strategy did not increase the incidence of infection and adverse outcomes.
