Does saline enema during the first stage of labour reduce the incidence of Clostridium difficile colonization in...

Maternal rectal enemas may reduce neonatal bacterial exposure during labour, which may reduce the risk of neonatal colonization with Clostridium difficile. The aim of this study was to determine the effectiveness of a saline enema during the first stage of labour in reducing neonatal colonization with C. difficile.

This study was conducted at Cairo University Hospital, Egypt from January 2016 to July 2016. Asymptomatic mothers with uncomplicated vaginal delivery and their neonates without diarrhoea were included. The study group underwent saline enema, and the control group had no intervention. Stool samples were collected from neonates one week after delivery. The primary outcome was the detection of C. difficile in stool culture and direct detection of C. difficile Toxin A and Toxin B by enzyme-linked immunosorbent assay.

The two groups were comparable (P>0.05) in terms of age, gravidity, parity, body mass index and gestational age. C. difficile was detected in 13.54% and 37.63% of stool cultures from the enema group and the control group, respectively (P<0.001). Direct detection of Toxins A and B was positive in 22.92% of cases in the enema group and 53.76% of cases in the control group (P<0.001).

This study suggests that a saline enema for the mother during the first stage of labour may be useful in reducing the risk of neonatal gut colonization by C. difficile.
