Input: For the 2013 update, we identified and excluded one new clinical trial. This updated review includes 14 trials, randomizing a total of 8033 women. The unstratified analysis found early intervention with amniotomy and oxytocin to be associated with a modest reduction in the risk of caesarean section; however, the confidence interval (CI) included the null effect (risk ratio (RR) 0.89; 95% CI 0.79 to 1.01; 14 trials; 8033 women). In prevention trials, early augmentation was associated with a modest reduction in the number of caesarean births (RR 0.87; 95% CI 0.77 to 0.99; 11 trials; 7753). A policy of early amniotomy and early oxytocin was associated with a shortened duration of labour (average mean difference (MD) - 1.28 hours; 95% CI -1.97 to -0.59; eight trials; 4816 women). Sensitivity analyses excluding four trials with a full package of active management did not substantially affect the point estimate for risk of caesarean section (RR 0.87; 95% CI 0.73 to 1.05; 10 trials; 5165 women). We found no other significant effects for the other indicators of maternal or neonatal morbidity. In prevention trials, early intervention with amniotomy and oxytocin appears to be associated with a modest reduction in the rate of caesarean section over standard care.
Output:

This review includes 14 trials, randomizing a total of 8033 women, and showed that a policy of early routine augmentation for mild delays in labour progress resulted in a modest reduction of the caesarean section rate compared with expectant management. The reduction in caesarean sections was most evident in the 11 trials looking at prevention of abnormal progression, rather than therapy (three trials). In these women, the time from admission to giving birth was also reduced (mean difference 1.3 hours). The trials did not provide sufficient evidence on indicators of maternal or neonatal health, including women’s satisfaction and views on the experience. Documentation of other aspects of care, such as continuous professional support, mobility and positions during labour, was limited as was the degree of contrast between groups. Women in the control group also received oxytocin but often later than in the intervention group. The severity of delay which was sufficient to justify interventions remains to be defined.
