Evaluation of neonatal sepsis screening in a tropical area. Part I: Major risk factors for bacterial carriage at birth in Guadeloupe.
This prospective study reports on screening for neonatal sepsis among 3,372 live births out of 6,060 consecutive deliveries at the University Hospital of Pointe-à-Pitre, Guadeloupe, during a 30-month period. Group B Streptococcus (GBS) was the most common pathogen, representing 46% (89/194) of positive blood cultures and 52% (335/637) of positive gastric aspirates. Although only 3,372 (55%) of all live births were screened, 637 (10%) had gastric bacterial carriage at birth; of those, 335 (5.5%) involved GBS. Similarly, there were 194 (3.2%) positive blood cultures, of which 89 (1.5%) involved GBS. In this report, all newborns who presented with a positive GBS blood culture had at least one of the external tests positive for GBS (gastric, ear canal, rectum and placenta). Thirty-seven per cent (14/38) of positive neonatal blood cultures occurred in newborns with foetid liquor while in deliveries with intrapartum fever 16.5% (32/195) of blood cultures were positive. In our clinical practice, characteristics that were evident in the delivery room (without knowledge of prenatal follow-up) such as foetid liquor, intrapartum fever, prolonged rupture of membranes, foetal tachycardia and meconium staining were associated with the great majority of neonatal sepsis.
