The systematic review on preventive interventions for the mother in the postnatal period
identified four randomized trials addressing prevention of sepsis in the postnatal period
(88–91). These studies, carried out in Denmark, France, the USA and Zambia, included
1961 women who had delivered vaginally. In three of the trials, women with a gestational
age of at least 37 weeks were eligible for inclusion (89–91); the remaining trial did not state
gestation at trial entry (88). Two trials included singleton pregnancies (89–90); Fernandez
and colleagues (91) included multiple pregnancies also, while this information was not
provided by Duggal and colleagues (88). The sample size of the studies ranged from 107
to 1291 participants
