Abstract
Objective: To examine the association between the duration of intrapartum antibiotic exposure (IAE) and the risk of culture-negative early-onset neonatal sepsis (EONS) and any late-onset neonatal sepsis (LONS) in the first week.
Methods: Preterm neonates (≤ 34 weeks) were enrolled into: Group A (no IAE; n = 282), Group B (IAE < 24 h; n = 204) and Group C (IAE ≥ 24 h; n = 84). The risk factors for EONS and LONS were noted and all neonates were followed up for culture-negative EONS (primary outcome). Secondary outcomes included culture-positive EONS, culture-negative and culture-positive LONS, and multidrug-resistant sepsis. A univariable followed by multivariable analysis of risk factors to predict culture-negative EONS and LONS was performed. The cut-off (Youden's index) of IAE associated with various outcomes was determined.
Results: From group A through C, gestation and birth weight declined, and the proportion at risk of EONS increased. Culture-negative EONS incidence increased (9.57% vs. 12.74% vs. 36.90%, respectively, Ptrends < 0.001), but its proportion among all EONS did not. Culture-positive LONS incidence declined (Ptrends = 0.038). The proportion of culture-negative LONS among all LONS increased (Ptrends = 0.024). Threshold values of 13.5 h and 4.5 h were associated with culture-negative EONS and culture-positive LONS in the first week, respectively. However, on adjusted analysis, IAE duration had no association with culture-negative EONS or LONS in the first week.
Conclusions: Duration of IAE is not independently associated with increased incidence of culture-negative EONS or any LONS.
期刊介绍:
The general objective of Indian Pediatrics is "To promote the science and practice of Pediatrics." An important guiding principle has been the simultaneous need to inform, educate and entertain the target audience. The specific key objectives are:
-To publish original, relevant, well researched peer reviewed articles on issues related to child health.
-To provide continuing education to support informed clinical decisions and research.
-To foster responsible and balanced debate on controversial issues that affect child health, including non-clinical areas such as medical education, ethics, law, environment and economics.
-To achieve the highest level of ethical medical journalism and to produce a publication that is timely, credible and enjoyable to read.
