Primary outcomePrimary: The Change in the Number of CRE (Extracted From Printed Monitoring Tracings Compared to Noted Nurses' Surveillance) Following the First Dose of Pentavalent Vaccine in Preterm Infants Born < 32 Weeks Gestation After Administration of Ibuprofen. — 0.1; 5.4 events/patient/24hours

Summary

Background: Inflammation may depress respiration in neonates. The aim of this study was to establish a link between post-immunization inflammation and cardio-respiratory events (CRE). Methods: Randomized double-blind controlled study of infants born <32 weeks gestation receiving the 2 months vaccine. Infants were randomized into an ibuprofen treatment group and a placebo control group. C-reactive protein (CRP) and prostaglandins E2 (PgE2) levels were assessed before and after immunization. CRE were recorded for 72 hours. Heart rate variability (HRV) was assessed by polysomnography.
